Lights Out For Migration!!

Help migrating songbirds by keeping our night skies dark.

Spring migration is well under way, but as far as songbirds go, it will really pick up steam for the month of May. Songbirds migrate at night, and they can become disoriented by artificial light. This can cause them to be drawn off their normal path and into a more dangerous urban area, where they may collide with windows and other human structures, or be taken by predators.

In 2021, Calgary became one of Canada’s first certified Nature Canada Bird Friendly Cities. Bird Friendly Calgary is the local organization whose mission is to highlight and mitigate threats that have contributed to a decline in bird populations of an estimated three billion over the last fifty years. As part of these efforts, Bird Friendly Calgary has a “Lights Out” initiative they would like to pass on to the local birding community. It is asking for everyone to turn off all unnecessary lights between 11:00 PM and 6:00 AM during the migration periods of spring and fall. For spring they are targeting April 1st to June 15th with special emphasis on the month of May. 

Please try to keep your houses and yards as dark as is safe at these times.

Lighted office towers are also a great threat to migrating birds and bats, and a huge number die or are injured each year in collisions with office buildings across North America. The Calgary Urban Species Response Team is active during migration in searching for such birds and bats in the downtown core, and trying to rescue any injured ones. The hope is that they can find out where the major problem areas are, and find ways to mitigate the loss of bird and bat life. See their site to find out more about this problem and the great work they are doing.

Birds, Bats, and Building Collisions

Window strikes, or birds colliding with windows, is a big problem – not just in residential yards, but in urban downtowns where tall glass structures are a big obstacle to migrating birds (and bats too). Many birds migrate at night, and skyscrapers can cause a lot of bird mortality. You may have seen some of the disturbing photos of hundreds of dead birds of many species that are collected in Toronto’s downtown every year by the Fatal Light Awareness Project (FLAP). A similar effort is undertaken in Ottawa by Safe Wings Ottawa.

Toronto, unlike Calgary, is located on a major migratory flyway. So how big is the problem here, and what can be done to minimize the damage? This is what Kathleen Johnson has set out to discover, by creating the Calgary Migratory Species Response Team.

Kathleen has done an amazing job of assembling a team of experts and setting up a detailed and well-prepared group of volunteers to begin surveys of Calgary’s downtown. The CMSRT will plot the locations of all birds and bats found, to learn where the problem areas are. The Calgary Wildlife Rehabilitation Society is directly involved as well, so that any injured animals can be rescued.

This weekend there will be a two-part orientation session for anyone wishing to volunteer. The first part will be an information and training session at the Central Library downtown, and the second part will be in the field (downtown) early Sunday morning. See the event on Facebook here.

Please visit the group’s Facebook page to learn more about this effort. You can also follow them on Twitter (@CalgaryResponse). If you want to volunteer, email them at calgaryresponse[at]gmail.com.

Tonight, August 22nd, Kathleen will give a brief overview of the project at the Birds & Beers event (6-9 pm, at the Legion at 9202 Horton Road SW) and will have more information available for anyone interested in getting involved. This is a really exciting initiative and I hope everyone can get behind it and help out!

Backyard Birds: White-crowned Sparrows

It’s a sure sign of spring in my yard when I see the White-crowned Sparrows are back.

A fairly large sparrow at 5 1/2-7″ (14-17 cm), White-crowns don’t fit the miscellaneous sparrow category of LBJ’s – little brown jobs – that are hard to distinguish from one another. These dapper little sparrows are always in bright white and black, and easy to identify.

The white crown has two black stripes, they have a black eye line (a line going to the back of the head from the eye), and a yellow-orange bill. They have white streaking on a brown back and wings, and their underparts are pale grey. Males and females look alike.

Small flocks of White-crowned sparrows pass through Calgary in late April to May, and then again in Sept-Oct. Their spring visits to our city are just a stopover for their trip to their breeding habitat in the northern boreal forest. They prefer open environments with shrubby meadows, alpine and willow shrubs, and build cup nests in shrubs or small conifers.

These sparrows are tireless singers, and are known to even sing under the light of a full moon.

Sparrows forage on the ground, usually in fairly open areas, and fly up into a small tree or hedge when flushed. We have a dedicated bird area at the back of our yard, and spillage from the hanging bird feeders provides an excellent sparrow feeding ground. Like other sparrows, the hyperactive White-crowns make quick jumping back and forth movements, scratching the ground to expose insects and seeds.

If you have White-crowned Sparrows in your yard right now, enjoy them while you can. They won’t be here for long, and then we’ll have to wait for their re-appearance in the fall.

By the way, the bird singing in the video background is a Ruby-crowned Kinglet, which I’m still attempting to capture with my camera.
