Watch Birds in Your Yard for the Calgary Christmas Bird Count

Posted by Bob Lefebvre

There has been a great deal of interest this year in the annual Calgary Christmas Bird Count. Matt Wallace, the Count Coordinator, and his leaders already have enough people registered to fill all the field teams. But if you’d like to participate by counting birds in your yard on Sunday December 19th, you are welcome to join us. You can count for as little as 30 minutes over the course of the day, or as long as you are able to – all at once, or intermittently.

White-throated Sparrow and Dark-eyed Junco (Slate), two species you might see in your yard in December.

For your observations to be added to the official count, you must live within the Calgary Count Circle:

The Calgary Christmas Bird Count Circle.

If you are interested in taking part, just fill out the registration form below (it is a Google form, but you do not have to be signed into a Google account to fill it out). Matt Wallace or myself (the Feeder Watcher Coordinator) will verify that you are in the circle, and contact you with everything you need to know in order to participate in this long-running Citizen Science activity. We can also send you information on common winter backyard birds of Calgary, with photos.

We are particularly interested in trying to get more complete coverage of the city with our Feeder Watchers. There are a few neighbourhoods which are under-represented, as you can see in the map below, which shows the approximate locations of all of our participants.

We would especially like to fill out this map in northeast Calgary, and there are a few other areas without much coverage, a shown below.

So if you live in one of these areas, please consider registering for the count. But we will accept you wherever you are!

Hummingbirds are Back! Put out Your Feeders!

Yesterday Marion Smolinski decided to put up her Hummingbird feeders in her yard in SW Calgary. This morning, a Rufous Hummingbird was at the feeder. It is really early but Marion thought she would put out her feeders early due to the mild spring we’ve had.

In Calgary the hummingbirds (Rufous, Caliope, and Ruby-throated) usually arrive back on about May 10. The way to remember when to put your feeders up is to do it on Mother’s Day. Maybe if you have a feeder you should put it up now.

Of course we can still have hard frosts for quite a while yet so you may have to bring your feeder inside overnight if frost is forecast.

Due to their fast metabolism (the fastest of any animal that maintains a constant temperature), Hummingbirds are always just a few hours from death if they don’t have a food source. To conserve energy they enter a state of torpor when food is scarce and at night when not actively feeding, slowing their metabolism to 1/15 of its normal rate and dropping their body temperature to 18 degrees C from 40 degrees.

Rufous Hummingbirds breed much farther north than the other species and are able to tolerate overnight freezing temperatures. If the birds are here, they have likely followed the blooming of flowering plants and the availability of insects, and unless we get a prolonged cold spell with daytime temperatures below freezing, they will be able to survive. Putting a feeder out is mostly for the enjoyment of humans and is not necessary for the bird’s survival.

If you do have a feeder out, it is important to remove any perches so that the birds have to feed while hovering. I know it is nice to see them perched but it poses a danger this early in the year. When a bird comes out of its nighttime torpor and goes to a feeder, if it rests on a perch its metabolism may drop again, and since it can be much colder at an exposed feeder than at their nighttime roost, they can die of hypothermia.

The bird in the above photo is perched on a ring on the feeder. I have one of these and have cut off the perching ring. Hummingbirds don’t need perches to feed.

The solution you put in your feeder should be made by boiling water and mixing one part white sugar (never brown sugar or honey) to four parts water, and then cooling it. It is not necessary to colour the liquid and that may actually be harmful. You don’t have to buy commercially available Hummingbird food, which is usually coloured red and can have nutrients added. Hummingbirds get all their nutrients from eating insects.

Good luck!
