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.

Sunday Showcase: Spotless Spotted Sandpiper

Posted by Matthew Sim

Okay, try saying that 10 times fast. Spotted Sandpipers, while spotted in their breeding plumage, do not have spots in winter or when they are juveniles.  Juveniles can be separated from winter plumaged birds by the scaling and barring on their upperparts, which nonbreeding adults do not have. Right around now, we start to see juveniles so look out for them; I recently found this juvenile in Votier’s Flats in Fish Creek Provincial Park.



Birding the Lafarge Meadows ponds

Posted by Matthew Sim

In the last few weeks, I have made several trips on my own down to the sloughs at Lafarge Meadows. There is always action there; be it coots feeding young ones, Pied-billed Grebes fishing, Ruddy Ducks courting, Red-necked Grebe diving or Yellow-headed Blackbirds chasing every other bird.

One of my favorite parts about the Lafarge Meadows sloughs are the Red-necked Grebes. I have counted as many as 4 pairs at a time on the ponds and have also enjoyed watching them court side by side.

Red-necked Grebe

The Red-necked Grebe is not the only grebe that can be seen at the ponds. The smaller Pied-billed Grebe also calls the sloughs home.

So far, I haven’t seen any young Red-necked Grebes but I have seen several families of Pied-billed Grebes.

There are also several other families on the ponds, including Mallards and Common Goldeneyes.

And while I was enjoying these great sights; I couldn’t forget the birds that truly make a southern Albertan slough like the Ruddy Duck, the American Coot, the Yellow-headed Blackbird- and of course, on the mammal side of things, the Muskrat.

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!

A Sharp-shinned in my yard

Posted by Matthew Sim

The other day, I was sitting outside in my yard, soaking up some sunshine when I heard a big commotion coming from the spruce tree in my yard. There were Grackles, Robins, Blue Jays, Pine Siskins, Chickadees and Red-breasted Nuthatches all making as much noise as they possibly could. The reason? Look at the photo below; do you see anything?

How about now?

Though the Sharp-shinned hawk was rather well hidden, it couldn’t hide from the neighborhood birds who know all too well what will happen if they leave this predator undisturbed.

Here are some more photos of this beautiful bird.

Hummingbirds of the Weaselhead

Posted by Matthew Sim

This past Thursday, I went out for a walk in the Weaselhead with local nature expert Gus Yaki and a group of other birders. Our target species were the 2 species of hummingbird that call this park home; the Calliope Hummingbird and the Rufous Hummingbird. Though we saw and heard many great species on our walk, for this post I will concentrate on the hummingbirds.

When we reached the area where Calliope Hummingbirds are usually seen, we scanned around with our binoculars, searching for this tiny bird. The smallest bird in North America at 8cm in length (3.25 inches), this hummingbird can sometimes be passed off as a large bee. After several minutes, somebody found this beautiful male perched at the top of a spruce tree.

Male Calliope Hummingbird

We observed this little guy (the Calliope is the smallest long-distance avian migrant in the world) as Gus told us many neat facts about the species. For example, the pink streaks on the male’s throat form a V-shaped gorget, and these streaks are rather long, so that when the male turns his head, the streaks will actually reach back over his shoulder. This was my first time seeing the species so I was particularly enthralled with the bird. After some time, we moved on, back closer to the river in search of the Rufous Hummingbird.

We had to walk through some muddy spots to get to the habitat where the male Rufous is likely to be seen but was it ever worth it! When we got there, someone soon spotted the male Rufous and we soon all had our binoculars trained on him as he displayed his gorgeous orange-red gorget.

Male Rufous Hummingbird

The Rufous Hummingbird was moving around a lot and we got to see him at various spots; perched and in flight.

At one point, he even came to the bushes right behind us and started feeding.  Gus told us that these bushes were actually Siberian Peashrub, more commonly known as Caragana. They are an invasive species that totally dominates the environment, so that no other flowering plants live in the area ( it covers 10-12 acres on the north side of the Elbow river). Male Rufous Hummingbirds  feed on these plants because of the abundant if  only temporarily nectar, however the females, which raise their families alone without the help of the males, realise that there is not enough nectar to raise a family on and head elsewhere, to richer, more natural environments. The males are then at a biological dead-end and do not have the oppurtunity to pass on their genes. This was quite fascinating and I would not have learned this had I not been on the trip with Gus. Thanks Gus!

He showed off his colors beautifully, revealing how he got his name.

We had a great morning watching these hummingbirds and learning lots about them thanks to Gus’ vast wealth of knowledge.
