Bird Profile: Tree Swallow

Posted by Matthew Sim

During the summer, Calgary is home to 5 species of swallow; Barn, Cliff, Bank, Northern Rough-winged and Tree Swallows can all be reliably found in the city during the warmer months. The Tree Swallow, perhaps the most common species of swallow here is a favorite bird of mine because of their personality. They always seem to be communicating with one another and I find it humorous to sit back from time to time and watch as a pair on a branch lean back and forth, chattering away to each other.

The Tree Swallow is, of course, a member of the swallow family, (the family is known by the latin name Hirundinidae) small, slender songbirds with small bills and long, pointed wings. A swallow’s sleek form allows it to be an “adept aerialist”, as described in the National Geographic field guides, and they use this form well as they are always darting and swooping about catching flying insects.

The Tree Swallow is separated from other swallows by its blue-green feathers on its upper parts and white plumage below.

Identified by its blue-green upperparts and white underparts,  the tree swallow can be seen flying around meadows and open fields and in wooded habitat near water, such as down along the river in Fish Creek. In fact, just last week as I was exploring some trails in Fish Creek Provincial Park by the river, I came across a Tree Swallow nesting in a cavity right at eye-level in a poplar tree.

Down in that hole, just out of eyesight, is the Tree Swallow’s nest, which is an open cup of grass lined with plenty of feathers- most will likely be from waterfowl on the river. As the Cornell Lab of Ornithology says about these guy’s nests; “the Tree Swallow uses many feathers from other birds in its nest. The feathers help keep the nestlings warm so they can grow faster. They help keep levels of ectoparasites, like mites, low too.”

Now, perhaps, you know a little bit more about these beautiful and graceful birds. I know that I learned quite a lot as I did research for this post. And though you probably see plenty of Tree Swallows during the summer here in Calgary, next time you see one, I want you to stop and just observe it for a while; I’m sure you will see that they have lots of character!

Family Time For The Birds

I had a day off this last Tuesday so I took the opportunity to go biking and birding in Fish Creek Provincial Park. It was a beautiful morning; the sun was out, the sky was blue, the birds were singing and the weather was warm; finally! I got to Fish Creek at around 8:30 a.m. entering the park just off the intersection of Canyon Meadows drive and Acadia . I was preparing to go down the steep hill into the park only to find that the trail was flooded! Instead I followed the trail around the ridge until I entered the park beside the ranch.I did some random wandering on small paths through Fish Creek, finding a pheasant, a kingfisher, several catbirds and 3 Yellow-bellied Sapsuckers, among other birds. I then carried on to bridge number 11, leading to Hull’s Wood. Rounding a bend in the path I was surprised to see a male Pileated Woodpecker, just  meters from the path. Before I could get my camera out of my bag, he had flown further away; apparently he was surprised to see me!

I reached Sikome Lake and rode my bike up the hill, in hopes of finding some Great Horned Owls and their owlets; I was not disappointed! There in their regular tree, was the Great Horned Owl family, two young ones and one adult.

As I continued my circuit, I found some more interesting birds, including some Green-winged Teal.

And the Pelicans! The water is so high in the river that pelicans are everywhere; I was able to count up to 27 pelicans at one time, half in the water, half circling in the sky, their bright white feathers contrasting magnificently with the clear blue sky. Another post on the pelicans will follow this one. However, this day, was truly the day of families. At one secluded spot near the river, I found 4 different nests all within a couple of feet of each other. The first belonged to a Downy Woodpecker, the second to a House Wren and the last two to Tree Swallows.

At the Downy Woodpecker nest, the male would visit the hole every couple of minutes and would be instantly greeted with the call of the hungry young in the inside. He continued his work incessantly, feeding his ever hungry offspring.

The House Wrens hardly ever came in and out of their nest but the male was always nearby, singing very loudly and stopping only for the occasional break.

The Tree Swallows would vigorously defend their nests from potential threats, such as the kestrel that flew over several times. The Kestrel in turn would chase away a Swainson’s Hawk that could have been a potential threat to the Kestrel’s family.

As I was leaving the park in late morning I came across a coyote sitting on a hill, looking very content as well as many Savannah Sparrows singing.

Family time for the birds is a busy time of year; I saw 52 species of birds that morning and I had luck as I got to see  some of them raising their families.

May Species Count – Longview Area

One of the areas that I surveyed for the May Species Count on Sunday May 29 was the Longview area, an hour SW of Calgary.  I was worried that I wouldn’t be able to get to some of the best birding spots due to the wet weather, but the conditions were pretty good.  There was water flowing across some of the side roads but I did get through.

This creek was very high…

There was still quite a bit of snow at high elevations…

The Bar U Ranch road, looking west to the mountains…

I managed to find 75 species, which is a good total for that territory.  I was quite frustrated near the end of the day by my inability to find a House Sparrow anywhere in the town of Longview!  No House Finches there either.  I also saw about 35 Black Terns in a pond that was just out of my territory, and they refused to come over to a perfectly good pond on my side of the boundary.

But I did have some unexpected birds as well, including two Red-breasted Mergansers.  Here are some other highlights (as usual, you can click on the photos to enlarge them).

Mountain Bluebirds are commonly seen near the bluebird boxes…

Female Mountain Bluebird…

Tree Swallows are nesting in many of the Bluebird boxes…

I got a good look at this Red-eyed Vireo…

Male Red-naped Sapsucker…

Because of the high water, there were few shorebirds other than Spotted Sandpipers and a few of these Wilson’s Snipe…

I was pleasantly surprised to find a pair of Harlequin Ducks on the Highwood River at the Green View campground…

I only saw one pair of Green-winged Teal, but this male swam very close to me…

The final surprise of the day was this beautiful Red Fox, which seemed to be completely unconcerned with my presence, and walked right by me…
