Furry Friday: Rodents of Carburn Park

Here are a couple of the largest rodents you can see in Carburn Park in SE Calgary.

These two species can sometimes be confused for each other, especially when they are swimming. Of course the Beaver is much larger but sometimes size is hard to judge in the field. Beavers have big flat tails but they are not always visible. Muskrats have long tails without fur. These photos show some of the differences that help with identification when the other traits aren’t clear: the big wide head with large nose and prominent ears of the Beaver, and the small face and often hidden ears of the muskrat. Fur colour can vary but around here muskrats seem to usually be reddish like this one.

Birds of Bridlewood and Carburn Park

Photographs of spring birds, by Tony LePrieur.

Yellow-rumped Warblers are usually among the first warblers to pass through Calgary on Spring migration, along with Orange-crowned Warblers. Most of the ones we get here are the Myrtle subspecies, the eastern and northern form, which have a white throat and a more prominent black mask. They breed in the boreal forest. The Audubon subspecies, shown here, breeds in the western mountains. This year, quite a few Audubons were reported here. There is talk that the two subspecies will be split again into two separate species, so it is important to note which one you see, especially if you are recording your sightings on eBird.

The Bridlewood Wetland is located just north of Spruce Meadows, on James McKevitt Road in SW Calgary. It is a small wetland but has a trail around it and a bridge from which to view the birds.

The rest of the photos were taken in Carburn Park on the Bow River in SE Calgary.

On spring migration, we get more Lesser Yellowlegs than Greater Yellowlegs in the city. But we do get both species. The Lesser is slighter, with a smaller head, and the bill is about the length of the head from front to back, as with this bird. The Greater Yellowleg’s bill is about one and a half times the head length, and often slightly curved upwards.

This Song Sparrow is missing its tail. Birds don’t molt their tail feathers all at once, so a missing tail probably indicates that the bird narrowly survived an attack by a predator.

Sunday Showcase: Summer in Alberta, Part 2

Tony LePrieur took these photos on the weekend of July 23-24, 2016. The Stilts were at Frank Lake; the rest in Fish Creek Provincial Park in Calgary.

Black-necked Stilts are a relatively new arrival in Alberta. They were first observed to breed in Canada in 1977, and are now found in several provinces. They breed as far north as the Edmonton area now. We are lucky to be able to see them breeding at many areas in the region, including at Frank Lake and Weed Lake.

Carburn Park – Part 1: The Ponds

Posted by Dan Arndt

My last two outings with the Friends of Fish Creek Spring Birding course were at Carburn Park, both on Thursday, April 17 and Sunday, April 20. Both days had their high points, and so I’ll be mixing and matching photos from each of those days here.

While each day we did the route a little differently, the best birds were always in the same spots. On Sunday, we headed down to the Eric Harvie Bridge then walked back along the river with the sun behind us. While there weren’t too many birds near the bridge itself, as we moved northward we found our first Common Goldeneyes, an American Beaver, and shortly thereafter, a lone Muskrat above the beaver’s dam!

We were also treated to some vigorously displaying Downy Woodpeckers, chasing each other up and down from tree to tree. These two especially were really going at it!

We headed up the river, seeing a few Tree Swallows, a few Ring-billed and Franklin’s Gulls, and even heard a lone Song Sparrow calling from across the river before we headed back into the denser foliage. Most interestingly though was a little spot we had found on Thursday which was host to half a dozen Ruby-crowned Kinglets was still holding one little one singing away while the sun shone bright…. unlike Thursday, which was cloudy, gloomy and rather snowy!

Up on the north end of the park we saw the local nesting pair of Bald Eagles in the distance, and both days it appeared that the female was still on the nest, brooding her eggs, while dad hunted for dinner.

The real highlight of the trip on Thursday though was seeing this flock of nearly a hundred swallows, both Violet-green (look for the ones with the white rump band above the tail) and Tree Swallows (all the rest of them, with the bluish-black backs) flying low over the river chowing down on their lunch of freshly hatched insects. While I had initially guessed that we had seen about four or five Violet-green Swallows, looking back over at my photos I was able to find at least 10 individuals, the largest number of that species I’ve seen in Calgary at once!

Of course, they weren’t there in any great numbers on Sunday, which was much warmer, and much nicer weather, but there was a beautiful Mourning Cloak butterfly, my first of the season, sunning itself near the second of the large ponds. It was a great end to a great day!

Thanks again for reading, and good birding!

Birds of the Weaselhead

Last week we went for a walk through the Weaselhead area of SW Calgary.  It was very wet and the rivers were high, but we did manage to find some nice birds.

The creek near the junction with the Elbow River.

Eastern Phoebes are nesting under both of the wooden bridges…

There are lots of Least Flycatchers in the area…

It appears that Beavers have chewed through this retaining wall, just to make it easier for them to get from the forest to their pond…

We saw this male Calliope Hummingbird do its spectacular U-shaped display flight, where it climbs to a height of about 80 feet, and then dives rapidly towards the ground, and up again…

We never saw any Pileated Woodpeckers, but there is evidence of their activities on many of the big trees…

Cliff Swallows at their mud nests under the bridge over the Elbow River…

A Spotted Sandpiper was feeding on top of some logs in the river…

Cedar Waxwings were busy flycatching along the waterways…

And there were several Red Squirrels, looking for handouts…

Coyote and Beaver

Guest Post: Coyote and Beaver

The amazing sequence of photographs below was taken last week by Rob English, who kindly shared them with us.  This interaction between a Coyote and a Beaver took place at the large pond just North of the highway 22X bridge, on the west side of the Bow River in Fish Creek Park.  The photos were taken on two consecutive days, so this is a persistent Coyote (assuming it is the same one both days).

Although this is a birding blog, we are interested in all aspects of nature, and we particularly love mammals.  One just doesn’t get the chance to see and photograph mammals as often as birds.  And one is rarely lucky enough to see an encounter like this.

If you have interesting nature photos that you’d like to share, please send them to us and we may post them here.

Thanks again to Rob English.

He got away.

Maybe if I sneak up from this angle…

He looks pretty big…

How about a sudden attack from this side?

Pretty big from this side, too.

Back to Meadow Voles…

Coyotes are very opportunistic feeders, and have been known to eat Beavers.  But a lone Coyote would have quite a bit of trouble with a full-grown Beaver like this one.  As you can see, the Coyote is quite hesitant to attack.
