Quite the act

Posted by Matthew Sim
Recently down here in Texas, the local Killdeer have started nesting and their nests can be found in many open spots, such as open lots and around athletic fields. Down at my high school, there were at least 2 nests around the track, which was quite surprising considering the amount of disturbance this location gets daily. While out for a walk last weekend, I found another nest near a local pond. I chanced upon this nest when the female Killdeer incubating her eggs scurried off her nest and proceeded to preform the Killdeer’s broken wing act to try and lure me away from her nest.


On the alert!

When Killdeer see a potential predator approaching their nests, they try to distract the predators from the nest by dragging one of their wings on the ground as though it were broken. They scamper away, stopping from time to time to make sure the predator is still following and then, when they feel a safe distance away from their nests, they fly off, returning to their eggs to continue incubating. It really is quite the trick!

Quite the convincing act!

Quite the convincing act!


I let myself be led away by this act but before I left I did make a brief attempt to find the Killdeer’s eggs, which I did, snapping a photo from a good distance away so as to ensure I didn’t disturb the Killdeer again before I left.

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.

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.

Sunday Showcase: More Starlings

Posted by Matthew Sim

This summer while I was up in Calgary, I noticed a lot of starlings as well, especially in Fish Creek P.P. On one of my excursions to the park, I positioned myself beneath a Starling’s nest hole and managed to capture a few shots as the bird descended to feed it’s young.

Preparing for landing…

Landing; note food in beak

At nest hole; seems to be startled by the ferocity of its two young!
