Bird Profile: Red-tailed Hawk

Jul26

Chances are you have seen this species before; this large hawk is one of the most widely distributed, numerous and commonly observed raptors in Canada. With a wingspan of up to 1.4m (58”) the Red-tailed Hawk is a highly variable buteo; soaring hawks that have wide tails and long, broad wings. Circling high up in the air, the Red-tailed Hawk can see mice scurrying about on the ground from 30 m (100ft) up .

This particular hawk in the photo appears to have done just that; he saw a mouse and then caught it, bringing the unfortunate rodent away to eat it, flying right over my head in the process of carrying off the mouse.

As mentioned before, the Red-tailed Hawk is a highly variable hawk with at least 14 recognized subspecies; ranging from the dark ‘Harlan’s Hawk’ to the ‘Krider’s Hawk’, a very pale subspecies of the Red-tailed Hawk.

Red-tailed Hawks love woodlands near open country; therefore, their habitat is diverse and they can be seen almost anywhere in Calgary. In summer, we tend to see light-colored morphs of the Western calurus the most and in migration and winter, we usually see dark morph ‘Harlan’s Hawks’. Also, in the southern part of Alberta, we have some krider’s Red-tailed Hawks. However, no matter what subspecies you see, they are still very impressive, especially when you get a good look at those talons!

Autumn Birding Course

Jul23

The best way to learn about birds in Calgary is to get out in the field with an experienced teacher.  The Friends of Fish Creek Park Society offers birding courses throughout the fall, winter and spring.  The weekly two-and-a-half-hour sessions are led by lifelong naturalist Gus Yaki and consist of field trips to various local natural areas.

You can attend Monday, Tuesday or Thursday mornings (the Saturday course is now full).  The cost is $50 for fourteen weekly sessions for Friends of Fish Creek Members, and $75 for non-members.  A membership costs $25.  See the poster here.   For information or to register, email chris@friendsoffishcreek.org  or call Chris at 403-238-3841.

Bird Profile: Red-winged Blackbird

Jul16

Up here in the northern part of the continent, we know when spring is here when the robins arrive. These are not the only harbingers of warmer days however; the Red-winged Blackbird heralds the arrival of spring as well, the males arriving before the females to claim their territory.

One of the most abundant and widespread birds in North America, the male is a striking bird; all-black plumage save for his bright red and yellow wing epaulets. The female is a heavily streaked brown bird with a light streak over the crown and above the eye. Males have harems of females living in their marshes, these harems can sometimes number up to 15, but up to one half of the nestlings turn out to be sired by a male other than the territorial bird. During the breeding season, Red-winged Blackbirds are rarely seen far from water and are communal nesters, often nesting alongside other species of blackbirds. Once nesting is over, the Red-winged Blackbird forms flocks and go out to forage over the countryside, returning to marshes to roost at night.

Red-winged blackbirds are a common victim of the parasitic Brown-headed Cowbird but this does not seem to affect the former`s numbers. The young are mostly fed insects, and this is exactly what the female Red-winged Blackbird pictured above is doing; she is feeding insects to a fledgling hidden in the grass. The male does a remarkable job and helps feed  the fledglings in is territory; there can be quite a few young birds to feed!

Red-winged Blackbirds may be seen at any marsh, lake or pond in Calgary with cattails and bulrushes. Don`t forget to listen; you can always tell if there is a Red-winged Blackbird nearby if you can hear the males distinctive “Conk-la-ree“ song.

Cowbird Catastrophe

Jul15

The Brown-headed Cowbird has become a menace to songbird populations all over North America. A small, stocky blackbird, the males have glossy black plumage and a rich brown head whereas the females are drab brown birds. What makes the Brown-headed Cowbird such a menace to songbirds is the lazy manner in which they raise their young.  Females will use all their energy over the breeding season to produce eggs, sometimes up to 50 a summer. They lay these eggs in the nests of unwary birds; usually at the cost of the smaller bird’s young. The young cowbirds usually hatch earlier than their foster parents chicks and therefore, get most of the food, which can ultimately lead to the death of the foster parent’s young. The Brown-headed Cowbird parasitizes more than 200 species of birds; the Chipping Sparrow being one of the most hard hit species.

In the above photo, there are 4 male cowbirds all looking up from my bird feeder at the arrival of a juvenile Grackle.

There is a history behind the cowbird’s parasitism. At one time, it followed the buffalo herds across the prairies, a nomad, and therefore could not raise its young, resorting to the help of unwitting songbirds. Following herds of buffalo, the Brown-headed cowbird’s range was limited to plains and prairies. Deforestation and forest fragmentation by humans, however, opened up the way for the cowbird and they started to parasitize more and more species. Due to deforestation, the cowbird has expanded significantly, both in range and in number and it now poses a threat to some species.

Several species, such as the Yellow Warbler, have developed defences against cowbird parasitism and recognize the cowbird egg. The female Yellow Warbler will make a roof over all the eggs, including her own, upon recognizing the cowbird egg. She will then lay her eggs again. Other birds will throw it out of the nest or abandon the nest all together.

This one species goes to show how much human actions can change the world around us.

Banff: A National Treasure Part 3

Jul14

Continued from Part 2.

For our final day in Banff, we went to Johnston Canyon, just minutes away from the Johnston Canyon campground. We packed up our trailer under sunny skies and prepared for the hike. As we went along our hike more and more clouds started to roll in…

    Johnston Canyon is one of two places in Alberta where Black Swifts nest and is also home to American Dippers, North America’s only truly aquatic songbirds. We started our hike, looking for Dippers and admiring the rushing water as it raced by us.

We continued on our way until we reached the Lower Falls, where a small tunnel gave us a closer look at the waterfall; spray from the water jumping about.

From the Lower Falls, we hiked up to the Upper Falls, looking for our target birds but failing to see them. We heard some Townsend’s Warblers, a difficult bird to see and we did manage to see a Pacific Wren, a race of the Winter Wren that was recently split and became its own species.

Common Ravens, which are readily seen in the mountains, were seen in several different places along the hike.

By this time, we were almost to the Upper Falls and now a steady drizzle was falling; it became heavier and heavier until it was raining quite hard. We made it to the Upper Falls, enjoyed the view and then beat a hasty retreat to our car, trying not to become wetter than we already were. We made it to our car, wetter than we would have liked before driving down the road several kilometers to the Castle Mountain chalets and stopping in a parking lot for a quick lunch. By this time, the rain had stopped (how convenient) and we stopped to admire a pair of Osprey’s and their nest as well as a Flicker nest right beside the road.

Our trip to Banff was great and I would readily do it again!
