Leucistic Rough-legged Hawk

Posted by Matthew Sim

We’ve done posts here on this blog about leucism before, which is when a bird has reduced pigmentation, meaning it has more white in it’s feathers than normal for the species. We’ve had some examples before, including a leucistic House Finch, American Robin, Ruby-throated Hummingbird and others. For the past few months, Calgary has had a very neat leucistic bird in the area. This Rough-legged Hawk frequents the area around Highway 40, just west of Calgary.

Now compare this with a more normal Rough-legged Hawk.

On January 1rst, I found this leucistic hawk on Highway 40 near its intersection with Range Road 40.

A walk in the Weaselhead

Posted by Matthew Sim

While currently back in Houston, Texas, I spent a very enjoyable 2 weeks in Calgary over Christmas. Despite the cold (!), I got out a couple times, including an afternoon walk in the Weaselhead Natural area, taking photos of the local bird life as I walked.

A couple of Ravens announced their presence with distinctive loud croaks; as well as some more unfamiliar vocalizations.

It was quite a nice walk and good to see so many waxwings.

 

 

Postcards from Texas: Yardbirds

Posted by Matthew Sim

As I’m sure many of you know, there can be some very busy points in our lives; right now I’m preparing for semester finals at school, keeping up with sports, preparing for a return to Calgary over Christmas and trying to keep up with the birding. While I can’t always get out, there is always time to notice the birds in my backyard. Here are some of the regulars.

By the time you see this I will be back in Calgary for 2 weeks; I’m looking forward to some good northern birding again!

Impressionism

 Posted by Matthew Sim

It was a bright, sunny winter afternoon in Calgary, nearly two years ago to the day. I had just retreated from a chilly walk around my neighborhood and was warming up when I happened to glance out the upstairs window. Upon doing so, I noticed a strange shape down on the snow. It took me a minute to figure it out, but once I realized what I was looking at, the story began to come together piece by piece. See what you come up with.

When you looked at this shot, you might have said that you see a bird’s impression in the snow. You would have been right. Now, you might have been a little more specific and described seeing a raptor’s impression. If you got this far, you did great. It’s not very easy to deduce much else. However, some may have gone even further, observing the shape of the raptor, comparing with descriptions in field guides and creating a list of possible suspects based on the fact that this was taken in Calgary, during the winter. If you came up with a few possible suspects, great work. But did you go any further?

If you did, you might have come up with a Sharp-shinned Hawk. You would be right. The wings are too rounded for Merlin or any other falcon, shape too small and body shape not to the right proportions of a buteo such as a Rough-legged or Red-tailed Hawk and the shape is once again far too small for either an eagle or a goshawk. Therefore it must be a Sharp-shinned Hawk. My neighborhood in Calgary has a healthy population of 4-6 Sharp-shinned Hawks so this make sense. From here, we can piece together a story,

Imagine a Sharp-shinned Hawk flying maybe 30-40 feet high, perhaps a little lower, circling at times. From its vantage, the raptor notices a small movement in the fresh snow below. Diving down, it attempts to nab a vole caught out in the open, plunging deep into the unmarked snow. Then what? Tough to say, and it will be a great mystery; we can only speculate at the final result but here is a breakdown of the photo.

I still wonder about the impression in the top right; what happened? Did the vole escape the hawk’s clutches the first time only to succumb to the second attempt? Did the hawk attempt to lift off without getting enough momentum the first go? Or was the impression in the corner caused  by snow falling off a tree limb?

It was quite interesting to see all the same, regardless of what the result was.

Nooks and crannies; the process of saving seeds

Posted by Matthew Sim

I maintain bird feeders in my yard in Calgary all the time when I am around. Suet feeders, a tray feeder for millet, a peanut feeder, a niger feeder for siskins and goldfinches, a feeder for sunflower seeds; you name it. I enjoy watching the regular species of birds (and squirrels!) come in to eat and the occasional unusual species. When I watch “my” birds, I often notice intriguing behavior; the way that the Red-breasted Nuthatches stored food is particularly interesting. The nuthatches take a seed from the feeder, head to my fence and hide the seed there in a nook or cranny. Later, whether it be days, weeks or months, they would eventually come back looking for the seeds, providing some entertainment as we observe their antics.

Is it down here, perhaps?

Maybe if I come at it from this angle…

Certainly is amazing what you can see from your backyard!
