Our Elders and their ancestors have cared for our Traditional Lands for over 6,000 years.

Protecting Pimachiowin Aki, which over 200 bird species rely on for survival, is an important example of how we care for the land,” says Poplar River First Nation Lands Councillor Eddie Hudson.

Since 2016, Poplar River Lands Guardian Norway Rabliauskas has been collaborating with scientists from Audubon’s Boreal Conservation program to better understand how songbird populations are changing in the face of climate change.

The first results of the ‘Songmeter Project’ are in.

“Songmeters record bird sounds,” says Guardian Brad Bushie, Poplar River Lands Guardians Program. Using knowledge of the land, Poplar River Lands Guardians placed the recording units at four sites across the traditional territory, he explains.

The number of bird species recorded allows us to analyze population changes over time,” adds Dr. Jeff Wells, Vice President for Boreal Conservation at National Audubon Society.

Guardians placed Songmeters in four survey sites in Poplar River First Nation throughout the spring of 2016

71 bird species were detected

At least 18 of the species detected have more than 70% of their breeding range confined to the Boreal Forest biome, meaning their survival relies heavily on healthy landscapes like Pimachiowin Aki

Two species were detected on more than half of all recordings:
- White-throated Sparrow
- Swainson’s Thrush

Five species were detected on more than 30% of all recordings:
- Blackburnian Warbler
- Ovenbird
- Song Sparrow
- Bald Eagle
- American Crow

At least 20 species listed as special concern, threatened, or endangered by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) are believed to occur within Pimachiowin Aki. The Songmeter project captured recordings of three of the bird species listed by COSEWIC:
- Common Nighthawk
- Eastern Whip-poor-will
- Canada Warbler

National Audubon Society’s recent study, Survival by Degrees, found that over two-thirds of North American birds are moderately or highly vulnerable to a global average temperature increase of 3°C by 2080. This includes many species detected at Poplar River First Nation, such as:
- Bay-breasted Warbler
- Cape May Warbler
- Canada Warbler
- Blackburnian Warbler

How the collaboration began

“We first talked with the Guardians and community, and asked if they would be interested,” says Jeff.

Norway says the project is a good fit for his community. “One of our goals is to develop new research partnerships. Plus, the project builds on the monitoring work we have already been doing.”

Indigenous Knowledge and Western Science come together

The Songmeter project relies heavily on Guardians, and the process of collaborating starts with listening and respect.

Listening to Guardians’ advice is crucial in a project like this, where Indigenous Knowledge and Western Science combine to create strong, respectful conservation efforts, says Jeff. “Things always overlay with Indigenous knowledge.”

Guardians serve as stewards and scientists and are central to a program that pairs data collection with Indigenous ecological knowledge to track changes across the site over time.

Guardians have a good understanding of the land and decide where to install Songmeters.

“Our Guardians’ hard work and understanding of the land have contributed to the project’s success,” says Councillor Eddie Hudson. “We are proud of the work they do.”

The project continues

This past year, Guardians installed Songmeters in the same four locations as 2016. The 2017-2021 recordings have yet to be formally processed but since the start of the project, the number of species the team has identified has “greatly expanded,” Jeff says.

Thousands of hours of song

Analyzing bird sounds can be a difficult and time-consuming task.

“What happens with this kind of work is that you can get thousands of hours of recordings, and you can imagine someone sitting down and listening… You can only get through so much,” says Jeff.

The relatively small team picked random samples, listening to four 10-minute recordings from each day collected in 2016.

187.3 hours of recordings were sampled between May 27 and July 1, 2016

New technology to speed up the process

Recently, the team implemented BirdNET in their identification process. BirdNET is an artificial intelligence algorithm developed by the Cornell Lab of Ornithology. This bird identification machine can quickly go through recordings to identify specific bird species.

The team will use BirdNet to help identify the recordings taken in Poplar River First Nation from 2017–2021.

Looking forward

In the upcoming year, National Audubon Society and Poplar River First Nation Lands Guardians Luke Mitchell, Brad Bushie and Youth Guardian Aiden Heindmarch will work together to expand the areas where Songmeters are placed. They plan to set up Songmeters in deeper and more remote areas of the forest.

“One place takes a couple of days to get to by boat,” Jeff says. “It’s exciting to see what we might find in these places.”

He hopes that over the years more First Nation communities can use Songmeters when developing their monitoring programs. He also hopes for more collaborative initiatives with communities in Pimachiowin Aki.

“If that’s what communities want to be a part of,” he says, “there are a lot of interesting things to discover.”

Species of Conservation Concern: Boreal Woodland Caribou

December 20, 2021

Across Canada, industrial activity and wildfires are changing forests and habitat for boreal woodland caribou. Pimachiowin Aki’s large stretch of intact boreal forest offers a rare haven for this majestic species—four groups of boreal woodland caribou live in the protected area, including one of Manitoba’s largest groups.

Boreal woodland caribou have been on the threatened species list in Manitoba since 2002. They were listed as a threatened species across Canada in 2003.

How Pimachiowin Aki meets the needs of boreal woodland caribou

Caribou Biologist Dennis Brannen, Wildlife, Fisheries and Resource Enforcement Branch of Manitoba Agriculture and Resource Development, explains that boreal woodland caribou thrive in Pimachiowin Aki, in part, because the vast landscape allows them to avoid predators. Boreal woodland caribou inhabit Pimachiowin Aki’s remote islands, peat bogs, and mature forest, which are typically not desirable for predators like wolves and species wolves prey upon, such as moose.

“Caribou exist in older mature forested areas where there is limited food types. Wolves have less reason to go into those areas because there’s less to feed them,” explains Dennis. Caribou are able to travel more easily in Pimachiowin Aki’s deep, persistent snow and wet peat bogs compared to wolves, he adds.

Pimachiowin Aki provides boreal woodland caribou with their preferred winter foods—lichens that grow on trees and the ground, typically found in spruce, pine and tamarack forests.

The human–predator domino effect, explained

Predators are not the root threat to Canada’s populations of boreal woodland caribou. “The general decline that we are seeing essentially comes back to human-caused landscape change,” says Dennis. Pimachiowin Aki has limited roadways and is protected from commercial mining, logging and peat extraction. In contrast, human activity across the country “has pushed the [caribou] population to the edges and restricted them to broken up patches of forests,” says Dennis.

Pimachiowin Aki is free from the adverse effects of industrial development.

When forest is broken into segments, it creates multiple issues for boreal woodland caribou. Dennis explains the domino effect.

“When forests are disturbed through human activity or natural causes like wildfire, regrowth is initially dominated by leafy shrubs, herbs and grasses—that new generation of vegetation is a surplus of food that leads to more primary prey species for wolves, such as moose.” Wolves follow and ultimately prey upon caribou, too.

Developments such as roads and trails also pose a threat. Dennis describes these linear features as “highways for predators.” They allow wolves to get into areas that were once less accessible, pick up speed, and prey on boreal woodland caribou.

Industrial development creates open areas in the forest, making boreal woodland caribou more vulnerable to predation.

Wolves are not caribou’s only predators. Other species will prey on them “when an opportunity presents itself,” says Dennis. “Across the boreal forest, black bears will prey on boreal woodland caribou calves. Out west in the Rocky Mountains, cougars prey on caribou, especially younger caribou,” he adds.

The climate change-predator domino effect, explained

Boreal woodland caribou travel well in wetlands. “When you bring climate change into the scenario, those wetlands become dryer,” says Dennis. In dryer times, wolves can get into those areas more efficiently. “This has implications for predation on caribou as well.”

Caribou birth rates

Another factor contributing to Canada’s declining boreal woodland caribou populations is that caribou don’t have as many young as other wildlife.

“Moose, elk and deer often have twins,” says Dennis, noting that this is rare in the caribou world. “Caribou will only have one offspring per year, so you end up in a situation where more [caribou] are being removed than added to the population in many cases.”

Ghosts of the forest—Caribou sightings in Pimachiowin Aki

Pimachiowin Aki Guardian Dennis Keeper reports seeing few caribou in Little Grand Rapids First Nation. “Fifteen to 20 years ago, we used to see hundreds and hundreds of them while traveling winter roads.” That is no longer the case. “I saw 14 of them two springs ago—a group of females. You don’t even see tracks now.”

Dennis Brannen suspects that caribou have started to avoid busier areas, like the winter roads. “Caribou are known as shadows or ghosts of the forest. They’re a secretive animal, so they don’t always show themselves when they’re around that landscape. They just shy away from where people are.”

Living with wildfire in Pimachiowin Aki

“Caribou have learned to live with fire [in Pimachiowin Aki] through time,” says Dennis Brannen. Fire is an opportunity for land to renew itself and create new and future habitats. “It’s only when we start increasing the amount of human disturbance on the landscape in combination with fire that we start seeing negative impacts on caribou populations,” he says.

But climate change could change that, warns Dennis. “With climate change, we potentially see an impact with the size of fires and frequency and intensity of those fires on landscapes. So, there are likely to be negative impacts to available habitat and population through time.”

Pimachiowin Aki is the largest protected area in the North American boreal shield. At more than 29,000 sq. km, it provides boreal woodland caribou with room to withstand the impact of fire-related habitat loss.

The future of boreal woodland caribou

Across Canada, people are combining western and Indigenous ways of knowing to protect boreal woodland caribou and their habitat.

“Our desire is to do a better job as we move forward to bring Indigenous knowledge into caribou conservation here in Manitoba,” Dennis shares.

Manitoba’s boreal woodland caribou recovery strategy sets out goals that align with Canada’s recovery strategy. A key goal is to manage and protect boreal woodland caribou habitat to sustain populations across the land. However, results will not happen quickly.

It’s a long-term process and we have to keep that in mind,” says Dennis. “We can’t just say, okay, we’re protecting undisturbed landscape and expect caribou to start doing well tomorrow. We need to look at opportunities and ways in which we can move disturbed habitat back into a state that is suitable for boreal woodland caribou use in the future.”

Research from across Canada indicates that when a habitat is disturbed by industry, for example, it takes roughly 60 years for that habitat to become useful to caribou again.

“We are constantly reviewing developments and proposals, and looking at how they may or may not impact caribou directly,” says Dennis.

There is hope for boreal woodland caribou. Last year, it was reported that the George River population (Labrador and Quebec) increased for the first time in 25 years. That area banned hunting of caribou in 2013. However, woodland caribou are not protected across the country. Their survival is tightly woven into the long-term health of boreal ecosystems, such as those of Pimachiowin Aki.

Anishinaabeg continue to provide wildlife, including threatened species like boreal woodland caribou, with healthy habitat. Here caribou will continue to feed in both winter and summer months and find safe spaces to calve and raise their young.

Boreal Woodland Caribou: Fast Facts

December 20, 2021

Anishinaabeg in Pimachiowin Aki generally do not hunt boreal woodland caribou—they are smaller than moose and harder to find as they are always on the move
Caribou hair is hollow, providing insulation in winter and buoyancy while swimming in summer
Boreal woodland caribou spread out to calve alone in remote areas, unlike barren ground caribou who calve in groups of females
Woodland caribou have a wide-ranging lifespan of eight to fifteen years
Caribou are the only deer species among which both males and females have antlers
Male antlers are broader and larger in size. Female antlers are generally shorter and slender and typically have only one point
Males shed their antlers in late winter and start re-growing them in spring
Females shed their antlers after calving
Caribou make a characteristic clicking sound when they move which is caused by tendons slipping over bones in their feet
Boreal woodland caribou have crescent shaped hooves that are wide and long— ideal for swimming (they act as paddles), walking on top of snow (they’re like snowshoes) and traveling across soft ground like bogs
Boreal woodland caribou prefer winter foods—throughout winter, they use their sharp-edged hooves to uncover and feed on Pimachiowin Aki’s abundant ground lichens
In summer, boreal woodland caribou thrive on Pimachiowin Aki’s diverse plant species, including grasses, lichens, shrubs and sedges
Boreal woodland caribou have been on the threatened species list in Manitoba since 2002. They were listed as a threatened species across Canada in 2003
Four groups of boreal woodland caribou live in Pimachiowin Aki

Historical Uses for Caribou

When thousands of caribou roamed, First Nation communities hunted them for a variety of reasons:

Clothing

“Some people use the hide for clothing,” explains Pimachiowin Aki Guardian Dennis Keeper. “It’s softer than moose hide.” Antlers are used to make buttons for clothes. Caribou hides were used for moccasins (makizinan). Caribou dew claws, adikwaganzhiig, were used in ceremonial regalia.

Drum-making

“Many years ago, the only reason we would hunt caribou would be for drum-making,” Dennis Keeper says. Caribou hide is thin and makes an excellent cover for a drum.

Tools

Antlers found in the forest are used to make scrapers, needles, and knife handles. Caribou bones are used to scrape off fat from beaver, otter and moose hides.

Lake sturgeon is the largest fish species in Pimachiowin Aki. An adult sturgeon can be 2.5 metres long and weigh up to 140 kilograms. Their ancestors date back millions of years.

Lake Sturgeon: Species of Conservation Concern

Today, this prehistoric giant is endangered. You can help protect lake sturgeon by recognizing its appearance and releasing it upon catch.

Who can legally fish lake sturgeon?

Only First Nations can harvest lake sturgeon in Manitoba. Lake sturgeon are protected in Manitoba and Ontario—both provinces ban sport and commercial fishing. Sport fishing is strictly catch and release.

In Canada, consult provincial and territorial websites to find out where lake sturgeon is protected by law. In addition, consult your local anglers’ guide for current sport fishing regulations.

How to identify lake sturgeon

The appearance of this evolutionary ancient fish has remained relatively unchanged for 200 million years. Here’s what to look for:

Adult lake sturgeon

Lake sturgeon vary in colour. Adults tend to appear olive-brown or slate grey with a white belly
Lake sturgeon have a row of bony plates known as “scutes” on their sides and back

Young lake sturgeon

Young lake sturgeon often have black blotches on their sides, back, and snout to help them camouflage with the lake or river bottom

Would you recognize a lake sturgeon if you caught one? Here is more identifying information.

Do lake sturgeon have teeth?

No, lake sturgeon have no teeth. They have barbels that dangle by the mouth. The barbels look like teeth but, in fact, are tube-like whiskers that help lake sturgeon detect bottom-dwelling prey such as snails, mussels, clams, crayfish, insect larvae and fish eggs.

Identifying lake sturgeon by location

Lake sturgeon are found in rivers and lakes ranging from Alberta to the St. Lawrence River in Quebec, and from the southern Hudson Bay region to lower Mississippi and Alabama. While lake sturgeon prefer to spawn in fast-flowing water, they are more commonly found in murky water where they bottom feed.

Identifying lake sturgeon by behaviour

Lake sturgeon have unique behaviours. The behaviours may be feeding strategies or just playfulness:

Tail walking
Lake sturgeon are known to stand above water on their tails and move backwards, especially in warmer weather.

Jumping
You may see lake sturgeon jump out of the water and twirl around like a dolphin.

Swimming upside down
Lake sturgeon have been seen swimming mouth up, on their backs, possibly to feed on insects on the surface of the water.

Are all lake sturgeon populations endangered?

The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) designates the following lake sturgeon populations at risk:

Population	Range	Status	Definition
Western Hudson Bay	Saskatchewan, Manitoba	Endangered	Lives in the wild but faces imminent extinction or local extinction (extirpation)
Saskatchewan-Nelson River	Alberta, Saskatchewan, Manitoba, Ontario	Endangered
Great Lakes – Upper St. Lawrence	Ontario, Quebec	Threatened	Lives in the wild and is likely to become endangered if steps are not taken to address the factors that threaten the species
Southern Hudson Bay – James Bay	Manitoba, Ontario, Quebec	Special concern	Lives in the wild and may become threatened or endangered due to a combination of biological characteristics and identified threats

Why are lake sturgeon endangered?

Several conservation issues have threatened lake sturgeon over the years:

1. Over fishing

Lake sturgeon reproduce only once every four to six years, so it takes them a long time to increase in population. If people are overfishing, sturgeon can’t keep up. This is exactly what happened, starting in the mid 1800s.

Mid 1800s

Caviar’s popularity was soaring. There was intense commercial fishing for female lake sturgeon and their eggs. Commercial fishers used nets to catch lake sturgeon as they swam toward spawning grounds.

Late 1800s

A lucrative commercial lake sturgeon fishery on Lake Winnipeg was developed under non-Indigenous control and largely for export to Europe. In the early days of this fishery, lake sturgeon was sold for its oil, not its meat. Lake sturgeon harvests were substantial. By 1891, overfishing became a serious threat to the species.

Early 1900s

Commercial fishing of lake sturgeon peaked. Over 445 tonnes of lake sturgeon were harvested in Lake Winnipeg, devastating the population.

1930s and 1940s

As lake sturgeon populations declined in Lake Winnipeg, non-Indigenous commercial harvesting began to take place in parts of Pimachiowin Aki. Commercial harvesting of lake sturgeon was largely unregulated. It took place mainly in spring, during spawning time. This had a significant impact on lake sturgeon populations. The species was unable to withstand the level of harvesting being done.

2. Loss of habitat

Migratory fish like lake sturgeon depend on the whole river, travelling long lengths of free-flowing water to reach shallow areas where they spawn. Climate change, poor water quality and construction of dams have all contributed to loss of habitat for lake sturgeon.

Dams and other manmade obstructions on rivers disrupt water flow and can slow or block access to spawning areas—lake sturgeon are strong swimmers but dams can cause currents that make it difficult for them and other fish to swim upstream. Dams can also contribute to changes in water temperature which affect reproductive success of lake sturgeon.

Climate change causes rising water temperatures, which in turn, decrease the quantity and quality of spawning areas.

How does Pimachiowin Aki protect lake sturgeon?

Pimachiowin Aki follows customary stewardship practices and Manitoba and Ontario laws. In addition to limited fishing, Pimachiowin Aki protects lake sturgeon by protecting its habitat from industrial development.

Pimachiowin Aki is a place where lake sturgeon can hide from predators, find food, grow to maturity, mate and spawn, and thrive. Food is plentiful, and waters are clean.

Plus, Pimachiowin Aki has many undammed and free-flowing riffle and rapid habitats, which are critical spawning areas for lake sturgeon.

Every plant and animal is a gift from the Creator and plays an important role in the ecosystem. In Pimachiowin Aki, we are monitoring the condition of habitat for species at risk, such as lake sturgeon. Lake sturgeon habitat is an important indicator of ecosystem health in Pimachiowin Aki.

Cultural significance of lake sturgeon

When we protect lake sturgeon, we are also protecting cultural heritage. Lake sturgeon provided a great source of protein for Indigenous families. A single sturgeon yielded twelve times more meat than most fish species.

Indigenous peoples cleverly used every part of the fish:

Parts of lake sturgeon	Use
Meat	Food source – cooked or preserved (dried on racks, cured by the sun or smoked)
Back bone	Used to make soup
Inner membrane of the swim bladder	Used as glue
Bones and cartilage	Shaped into needles
Tail bones	Shaped into spearheads and arrows
Oil	Burned in lamps, used to soften homespun wool, mixed with red ochre to create paint used for pictographs

Sturgeon is also an important clan emblem in Pimachiowin Aki. In Ojibwe, the Sturgeon Clan and its totem are called Name (pronounced Nah-MAY).

How Name Inawemaaganag, the Sturgeon Clan, came to be

A long time ago there was a couple. They were destitute. They had nothing but a baby boy. The couple was too hungry and weak to hunt. They decided to put their baby on a tree on the shoreline, hoping that someone would see the baby and help them. The couple changed into sturgeon. A group of people passed by and took the baby to raise as their own. Years later the child liked to play on the shoreline, near the water. One day he was sad and crying. Two big fish swam up to him. He knew they were his parents. Later in a shaking tent ceremony, the child learned that they were indeed his parents. This is how the Sturgeon Clan came to be.

What Birds in Pimachiowin Aki Can Tell Us

March 15, 2021

Pimachiowin Aki is the largest protected area in the North American boreal shield. It is home to millions of trees, pristine waters, and over a thousand plant and animal species—making it a paradise for songbirds, shorebirds and waterfowl.

The Natural Resources Institute (NRI) at the University of Manitoba and Pimachiowin Aki Guardians are working together to observe birds and discover what they can tell us about the health of the land.

During our first virtual meeting in 2020, these people shared their thoughts:

Melba Green, Guardian, Bloodvein River First Nation
Dennis Keeper, Guardian, Little Grand Rapids First Nation
Dr. Nicola Koper, Professor, NRI
Chris De Ruyck, PhD Student, NRI
Alison Haugh, Executive Director, Pimachiowin Aki

What do you hope to learn from this project?

Melba: My hope is for us to understand birds’ ways of living and the messages that they bring about weather and climate. If we see birds dying there is a problem.

Nicola: I am particularly interested in how lands managed by First Nation communities contribute to the conservation of birds. How are the birds we find in Pimachiowin Aki different or similar to birds outside the World Heritage site?

Chris: Bird species you find on the land can also tell you things about the land. Our goal is to examine how birds in Pimachiowin Aki are protected in comparison to places where the land has been altered. If species are present in Pimachiowin Aki but missing in other areas, it might point to a specific problem.

Nicola: I think that western science has a lot to learn from the stewardship of Pimachiowin Aki First Nations. By comparing birds in Pimachiowin Aki with how well birds are doing outside of Pimachiowin Aki, we hope the project will help make western-contemporary society better stewards of the land.

What do you mean by conserving birds?

Nicola: Birds can be harvested and populations can still be conserved at the same time. When I talk about conserving birds, I mean trying to protect ecosystems to protect birds that live there. We want to make sure bird populations are high across large areas, including Pimachiowin Aki and other regions, and are not declining.

What is the state of birds today?

Nicola: In most parts of North America, many, many species have declined over the last four to five decades. We don’t know a lot about birds in Pimachiowin Aki yet, but we think that Pimachiowin Aki may be a refuge where bird populations can be successful because the habitat is being protected. There’s a lot of habitat and food, and less noise and disturbance. The land is kept well, and people living on the land have a good relationship with it.

What can we learn from this project?

Melba: One of the rules of being Anishinaabe is to respect every living thing on Mother Earth. That’s why we wanted to create the Bloodvein River First Nation land use plan—it says all living species and their habitats will be protected.

Nicola: I like the idea of documenting the outcome of that respectful interaction with the land. Our hope is that we’ll be able to see how populations are changing over time, compare this to other areas, and show how important it is that birds have the habitat that Pimachiowin Aki is providing.

Why did Pimachiowin Aki choose to collaborate with NRI?

Alison: The project helps Pimachiowin Aki meet the monitoring and reporting requirements of being on the World Heritage List. We must show that we are taking active measures to protect the site’s natural and cultural values. This is just one of the many community initiatives that help keep the land.

Melba: This is a very interesting project and it is another way of being a Guardian. Observing birds is another way for me to learn. I can learn from [NRI]. Birds are fascinating. It’s teaching me something else rather than just the four-legged animals.

Why did NRI choose to collaborate with Pimachiowin Aki Guardians?

Nicola: We know different things—Guardians have knowledge of the area and how birds are using the land while NRI can provide information on how to identify birds and the locations they are likely to be found in. We’re bringing together our knowledge with the knowledge of the community. It wouldn’t work if it were just western scientists coming in.

Why study birds to learn about climate change?

Chris: We focus on birds because there are over 200 bird species in the boreal. We can gather information on many species at the same time, which makes it an efficient way to obtain information about ecosystems.

In addition, we know a lot about birds. Indigenous communities like Pimachiowin Aki have been passing down traditional knowledge about birds for generations. Plus, birds have been studied a lot by western science. This gives us a strong starting point—we know how to identify birds and we know how they typically behave. If their behaviour changes, we can link it to how healthy the boreal ecosystem is.

What kinds of things will Pimachiowin Aki Guardians be watching for?

Nicola: If you see multiple species arriving earlier than normal, that is one indicator that could help us understand if there are changes over time. Also, looking for new species or species that are more abundant than in other years.

Dennis: We’ve started to see new ducks that are black and look like the bufflehead. They’re all black except for a white mark on their bills.

Nicola: Possibly American coots—this is an example of a species that would be interesting to monitor because the community is noticing it and you haven’t expected to see it before.

Chris: New species showing up, and also species that are conspicuous by absence. Ones that disappear are equally important. Even seeing birds that are switching a food source and eating new things could be indicative of climate change.

Nicola: Fire can also change where species are found.

Melba: After a fire, you don’t see wildlife until the land restores itself. The birds will fly by and look around but they won’t go near a place when it’s burned. Once there is grass then you see them come back.

Nicola: Eventually, we want to go to Pimachiowin Aki, meet in person, explore the landscape together and decide what bird species to monitor. Initially, we’ll try to monitor all the species we can, but we will probably end up focusing on 20-40 species that are abundant, and that people see regularly.

Chris: We can also choose species that use different habitats and live in Pimachiowin Aki during different seasons, like summer and winter. Also, species that other animals in the boreal forest depend on, like woodpeckers, which have an effect on the forest. They help control western pine beetles by eating them, and they create cavities in trees, creating homes for insects, flying squirrels, owls and other birds. Even mice have been found in cavities created by woodpeckers.

Melba: There are lots of red-headed woodpeckers in Bloodvein. I have a book here on North American birds, which I take with me when I’m on the land. There are lots of birds! An Elder said that birds are coming back that haven’t been seen in a long time.

Nicola: I love hearing these stories and I hope to have more of these conversations with you.

Dennis: We have golden eagles. They have a nest here that they go back to every year. They look bigger than the bald eagle. On my trapline, where I hunt ducks, there are seven different pairs there. When I first started hunting, there were no eagles there. They anticipate us going there to hunt and they go there to clean up.

We are also seeing some kind of doves.

Is it bad to see exotic bird species in Pimachiowin Aki?

Nicola: It’s not a bad thing if exotic species are not highly abundant, but if they are abundant there’s always a risk that new species will push out native species. In places where there are a lot of house sparrows, there are often fewer chickadees and nuthatches.

How does this relate to climate change?

Nicola: Some birds probably thrive in Pimachiowin Aki because they are tough and able to tolerate cold winters. As weather conditions become milder, new species are also able to live in northern areas like Pimachiowin Aki. There is probably room in Pimachiowin Aki for more birds, but as new birds move in they might push the native birds out, away from a great food source. Populations are declining everywhere, so if birds get pushed out and end up losing refuges like Pimachiowin Aki, they will have even more problems.

How Bird Populations are Changing in Pimachiowin Aki

March 15, 2021

Dr. Nicola Koper, Natural Resources Institute

Selections from telephone interviews and conversations between Pimachiowin Aki Guardians Melba Green (Bloodvein River First Nation) and Dennis Keeper (Little Grand Rapids First Nation), and Dr. Nicola Koper, Professor, and PhD Student Chris De Ruyck of the Natural Resources Institute (NRI).

What birds are you seeing in Bloodvein River and Little Grand Rapids?

Melba: We see a lot of blue jays here in Bloodvein. A lot of people are feeding birds and blue jays come around.

Dennis: We rarely see blue jays. Or ptarmigan. But in the last couple of years, the ptarmigan are coming in huge flocks—200 or more! It used to be 10-20 in a group. We have had them covering this whole area. People are asking if you could eat them. People harvested them and saw that they were carrying some kind of bugs.

Nicola: That is really cool. We’ve had records of a few flocks near Winnipeg. They are not supposed to be here, so far out of their range. If we have species moving out of their natural range, they might be exposed to parasites that they are not tolerant of. If you have a species that evolved in the north, they might not be resistant to parasites in the south. It might be possible that ptarmigan are having problems in Pimachiowin Aki because it’s an area where they are not supposed to be. We could work with a parasitologist on those kinds of things—study where birds are and what health they are experiencing.

Dennis: Last year, the geese went back really early, around the last week of August. It’s usually the middle of September when you start to see the real migration. I don’t think they even nest around here anymore. I found a few eggs. And I didn’t see any snow geese pass by this way this year.

Nicola: I hope we can learn more about that through the type of monitoring we are talking about here. I’m interested in the common nighthawk and Canada warbler because they are species at risk. I’m also interested in exotic species like the house sparrow and European starling, which are starting to move further north because of climate change. It would be interesting to know if they have higher or lower populations in Pimachiowin Aki than in areas that are more influenced by western society.

Dennis: I’m concerned about the Canada jay. They store their food in black spruce. With the warming, their food goes bad and they abandon their nests. We used to see them everywhere. In the last four years, I have only seen one. It was by itself. Usually, we see them in groups.

Nicola: I also think that I have not seen as many [Canada jays] in the last couple of years. This is one of the species that we would be able to monitor. By being on the land, there is so much opportunity for you to make these observations.

Dennis: I’ve also been trying to find out about this one type of bird I’ve been observing for years. It’s dark in colour but when I get closer it’s greenish in colour and has a yellow banana nose. It’s nesting in buildings like the water treatment plant.

Nicola: Maybe the European starling. Look for little specks on them. They are black with iridescent green and purple.

Dennis: Short tail?

Nicola: Yes! The observation you made is really interesting because the European starling is a species that is very closely tied with humans. The fact that you might have them nesting there in buildings, tied with human structures, could mean that it’s what you’re seeing.

Chris: European starlings are not native to North America but I think they helped us out with the canker worms [last summer]. Birds love those outbreaks. Even if adults don’t eat the worms, they feed them to their young.

Nicola: Most species, even if they eat seeds, don’t feed seeds to their young. They feed them insects because insects have more protein than any plant matter would. That’s one of the reasons we don’t want to lose birds—because they perform roles that are good for wildlife and people.

Dennis: This year, I saw an eagle in January. It was a warm day. We usually see spring birds in March—known as the eagle moon month because eagles return to Pimachiowin Aki in March. They come before the geese. They wait for them to bunch up, then they attack them at a certain time of the day.

Chris: It will be really interesting to hear how birds this year are different from next year.

Melba: I can’t wait! I’ll take my camera with me out on the land, and take lots of pictures.

Chris: It can be hard to get a good picture. When you get your camera on them, there’s an idea that the birds might think it’s a large eyeball staring at them, like an owl or something, and they might not like it very much.

Melba: I know birds don’t like you bothering them. You have to stand around for quite a while until they come back.
