Birds and climate change: can they stay or will they go?

Jump ahead thirty years—will you still find the sights and sounds of your favourite birds in national parks? By 2050, one in four birds in Parks Canada places may need to find new homes as a result of increased greenhouse gas emissions.



Parks Canada and its partners have collaborated on a national study to understand the impacts of climate change on birds—and how we can protect them, and help them adapt.

The messengers

Birds are among the most studied animals, and what they are telling us about climate change is alarming: birds and their habitat ranges are being impacted at local and global scales.

“Climate change is affecting all species. And like many other people, it was through birds that I could begin to see its impacts on species first hand. However, it’s one thing to witness local changes—but it’s staggering when you see the global significance of the impacts to bird populations in the data from countless other birders and research scientists.”

Dr. Scott Parker
Ecosystem Scientist at Parks Canada.

As climate changes, habitat suitability for the different bird species living in a park will either improve, worsen, or remain stable. Birds may colonize new areas, or become extirpated – locally extinct – from places where they are found today. This will depend on the season, the location, and the bird’s ability to adapt to changing conditions.

Field Notes Vlog: The Future of Birds in a Changing Climate

Text transcript

[Darroch] My name is Darroch Whitaker.

[Darroch] I'm an ecologist at Parks Canada.

[Darroch] Just getting ready to head out for a day of ecosystem monitoring at Torngat Mountains National Park.

[Darroch] Our pilot, Kyle, is getting the helicopter ready behind us.

[Darroch] We're leaving here from Torngat Mountains Base Camp and Research Station, which is our base of operations when we're doing fieldwork in the park.

[Darroch] A lot of the work we do in Torngat Mountains National Park has been focused on climate change and the effects of climate change on ecosystems and the environment in the Park.

[Darroch] One of the things we're seeing happen, is what we call shrubification.

[Darroch] It's happening all across the Canadian Arctic, but essentially tundra ecosystems converting to more of a shrub-type ecosystem.

[Darroch] On this hillside here in Nakvak Brook, you can see the green growing up the valley sides.

[Darroch] That's one of the consequences we're seeing, is that the greening of the tundra, the greening of the Arctic, is leading to an increase in expansion of vegetation up into the higher elevations.

[Darroch] I'm a bird biologist; that's my academic background.

[Darroch] So everywhere I go, I carry my binoculars with me.

[Darroch] And basically every bird I've seen, I write down a note on what species it is, how many are there, and whether there's any breeding evidence.

[Darroch] So at the same time, you're seeing shrubs change in this national park.

[Darroch] We're seeing the bird communities respond.

[Darroch] We have a lot of information to suggest that species should be shifting their ranges northward as global warming proceeds, and I've actually seen that with some of the data I've got here.

[Darroch] Some of the observations show that a whole group of boreal bird species are starting to colonize the Torngat Mountains.

[Darroch] This is exactly the kind of habitat that a lot of the boreal birds that are expanding in the national park are using...

[Darroch] ...they're moving into these areas, these thickets.

[Darroch] This is actually interesting because we have some historical photos of this location from a camp that was here in 1990.

[Darroch] These things are alders.

[Darroch] They're about two metres tall now.

[Darroch] These weren't here 30 years ago.

[Darroch] So Holly's measuring the height of the dwarf birch at one of our plots here,

[Darroch] we'll do five of these plots at each site.

[Holly] So, this one's actually, like, a 44. Yep... Catkin...and no browse.

[Darroch] Okay. Done here and we'll go on to the next one.

[Darroch] So we're here at Ramah Bay in Torngat Mountains National Park.

[Darroch] This is our last day of real fieldwork for 2021.

[Darroch] It's been a pretty successful year, although a little bit more damage than usual to some of our monitoring equipment.

[Darroch] We're just downloading a few last air temperature and soil temperature loggers and doing some repairs.

[Darroch] What's the story?

[Holly] So, it should be fine...we just need to put a new bracket on it.

[Darroch] Okay.

[Darroch] So we're all finished at Ramah Bay for this year.

[Darroch] We've got a slightly taller post installed, jerry-rigged with the parts that we had available to us today.

[Darroch] Fingers crossed for 2022 that the bears can't reach our air temperature logger on top and pull it down.

[Darroch] So it's August 13th, our last day in Torngat Mountain's Base Camp and Research Station.

[Darroch] We're just heading out to visit a research site from the doctoral research of Dr. Laura Siegwart Collier, who works for Parks Canada.

[Darroch] She's here behind me and we're going out to visit some "OTCs" or open-top chambers.

[Laura] So these simulate climate change and effects on tundra plants...

[Laura] and we're going to see how they're doing several years after they were put out here.

[Laura] So, what it does, what it's meant to do, is to block wind so that you have less heat loss for the ground vegetation.

[Laura] And it's been shown that these greenhouses increase temperature by about one degree Celsius compared to places where they don't have a greenhouse.

[Laura] The vegetation are growing taller, they're shrubbier, there's just generally more plant biomass inside these little greenhouses when compared to our outside plots.

Torngat Mountains National Park is cooperatively managed between Parks Canada and Inuit from Nunatsiavut and Nunavik. Together, they use Inuit Knowledge and science to track landscape changes and ease potential impacts. Watch the video in Inuktitut.

Birds on the move

Every species of bird needs certain environmental conditions to thrive. These include things like temperature, precipitation, suitable habitat, and landscape connectivity. When conditions are no longer suitable, birds may be forced to relocate—or perish.

A small bird with grey and copper coloured plumage is perched on a tree.
The Boreal Chickadee is expected to lose much of its current habitat due to climate change.

Keeping it fresh

A grey and white coloured bird is perched on the branch of an evergreen tree in the wintertime.
Canada Jays are finding it harder to store their winter food supplies as the climate warms.

Meet the iconic Canada Jay. This songbird is one of the first species to nest in Canada's cold boreal forest each year. They start to build their nests and lay eggs as early as February and March.

Canada Jays survive by hiding small food caches in thousands of spots to get them through the winter and nesting season. They depend on cold winter temperatures to keep this food fresh and nutritious.

Warmer winters are causing these birds to suffer. Their precious food stores are decaying from regular freeze-thaw events. This is reducing the nutritional value of their food. It is also leading to failed nests and lower populations.

[Canada Jay chirping and forest noises]

A Canada Jay sits perched on a branch in front of a boreal forest, moving its head slightly.

[Text on screen: As climate changes, birds’ ranges are shifting.]

[Label: Canada Jay, Perisoreus canadensis]

A dark green map of Canada showing Parks Canada National Parks and Marine Conservation Areas appears, along with an illustration of a Canada Jay in the upper left corner.

The Canada Jay’s summertime range under current temperatures appears as a bright green area that spans across much of Canada. The bright green colour represents a stable range.

The temperature scenario changes to +1.5° C warming. The Canada Jay’s summertime range begins to shift; a small portion of the range in the south turns red, indicating a portion of that range is lost. The middle portion of the range remains bright green, or stable. A small section of blue appears in the north, indicating Canada Jays are predicted to gain range in the north.

The temperature scenario changes to +2° C warming. The Canada Jay’s predicted range shifts further north. The portion of their stable range shrinks, as it loses range in the south and gains range in the north.

The temperature scenario changes to +3° C warming. The Canada Jay’s predicted range shows dramatic losses in the south, very little stable range remaining, and a moderate amount of range gained in the north (though, less range than what was lost in the south).

The range change is repeated three times.

Even minor changes in climate can have major consequences. The negative impacts of climate change will be much less if we can keep global warming to 1.5°C instead of 2°C.

Protecting birds—together

Parks Canada, the National Audubon Society, Birds Canada, and the Canadian Wildlife Service are collaborating to better understand how climate change could affect bird species in protected and conserved areas.

Their research findings predict that if climate change continues, bird communities across all places administered by Parks Canada will be different by 2050. Sites in the Atlantic, Quebec, and Great Lakes regions are expected to see the greatest changes in species composition.

Finding a new home

As the climate continues to change, some birds may need to find new homes. In mountainous regions, that could mean moving up to higher elevations. In most other areas, it will mean a move northward.

Some birds may not find enough or suitable habitat conditions, and therefore would not survive. This could lead to population declines and shrinking ranges.

This search for new homes is a big challenge for birds. In their journey to migrate, birds face risks like predators, bad weather, lack of familiar foods and habitat, and exhaustion. New neighbours may not be welcoming.

The male and female Northern Cardinal are also being spotted in places where they never used to live before.

“We can’t assume that generalist species will do any better than specialized species. But it is fair to expect that those species already experiencing habitat loss, like grassland birds, will continue to suffer the most. Adapting to climate change will be tough for all birds.”

Dr. Scott Parker
Ecosystem Scientist at Parks Canada.

Space for birds to breathe—to adapt

Protected and conserved areas give birds and other wildlife breathing space, allowing them to adapt and survive. These areas are still impacted by climate change. However, they may have fewer stressors, like habitat loss by human encroachment, resource extraction, and pollution.

These areas are becoming “climate refuges”; places where the effects of climate change are less pronounced. In these places, mountains allow species to move upslope to cooler climates. Lakes can absorb heat and produce cooling breezes. Healthy ecosystems may be more resilient to stressors.

Vulnerable bird species, like the endangered Whooping Crane in Wood Buffalo National Park, will depend more on protected areas as their environment changes.

Parks Canada works with partners to conserve bird habitats beyond park boundaries. They create habitat “stepping stones” that improve connections between protected areas. These give birds and other wildlife a chance to move and adapt.

Your role in protecting birds

Fewer birds will need to find new homes if we can work together to reduce greenhouse gas emissions and slow global warming and its impacts. As well, by doing your part to reduce other human caused stresses on bird populations and the environment.

Birds can’t fight climate change, only we can. If we act now, we can reduce the impact of climate change and improve the chances for hundreds of bird species.
