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.

Furry Friday: Hares Changing Colour

Here are three recent photos of Snowshoe Hares taken in the Weaselhead in Calgary, showing the transition from their white winter coat to their brown summer coat.

Weaselhead and North Glenmore Park in Early April

Posted by Bob Lefebvre

For the first week of the Friends of Fish Creek Provincial Park (FFCPP) Society’s spring birding course, the groups birded the Weaselhead from the north parking lot down to the other side of the bridge over the Elbow River, and North Glenmore Park, including the stormwater ponds opposite the canoe club. The goal was to look for some spring migrants such as American Tree Sparrows in the Weaselhead and for Swans on Glenmore reservoir, and possibly Snowy Owls on the remaining ice.

Max Ortiz Aguilar went with the Sunday morning group on April 9th and took photos of some of the birds and mammals they saw, including the Trumpeter Swans shown above. Glenmore Reservoir is a good place to find migrating swans in spring once the ice begins to go out. (All photos taken with a Canon 6D and a Tamron SP 150-600mm.)

In the Weaselhead, the group spotted American Tree Sparrows.

Tree Sparrows are arctic nesters and an early migrant in the spring. Sometimes a few will overwinter here. Note the reddish streak behind the eye, the two-toned bill (black above, yellow below) and the dark central breast spot. These features distinguish it from the similarly rusty-capped Chipping Sparrow, a species which is common here in the summer but which doesn’t arrive back until early May.

The Weaselhead is a great place to find mammals too. Snowshoe Hares are common, and are now mostly in their brown summer coats.

Red Squirrels and Least Chipmunks often are seen at the bird feeders by the path through the Weaselhead.

Late Winter Birds

Posted by Bob Lefebvre

It’s spring on the calendar and new migrants are arriving daily. Some of our winter birds have departed, and some of our resident birds are beginning to nest. Here are some photos of birds of late winter in Calgary. All photos by Tony LePrieur.

Bohemian Waxwing, Calgary, February 19, 2017.

Bohemian Waxwings are only here in the winter. Since mid-March only small flocks have been reported. Most have departed to the north and to higher elevations. By the end of April they all will be gone.

Mountain Chickadee, Weaselhead, Calgary, March 12, 2017.

Mountain Chickadees are only occasionally seen inside the city, and most often in the west end where the boreal forest creeps in. This winter there were several seen in the Weaselhead and in Fish Creek Park. They are usually absent in the summer, as they breed west of the city.

Pine Grosbeak (female), Calgary, February 19, 2017.

Pine Grosbeak are one of our winter finches and they were here in low numbers this winter. They move to higher elevations and to the north in the summer.

Downy Woodpecker, Weaselhead, Calgary, March 12, 2017.

Downys are one of our resident woodpeckers and they have been paired up for at least a month, and are now beginning to nest.

Northern Flicker (male intergrade Yellow-shafted/Red-shafted), Calgary, February 19, 2017.

Northern Flickers are also woodpeckers, but are migratory. However, many overwinter here, which may include local birds or ones from farther north. They are currently pairing up for nesting, and it is common to hear their calls and drumming (they often drum on metal chimneys or street lights).

Most of the local flickers are intergrades of the two subspecies (Red-shafted and Yellow-shafted) and they often show mixed field marks, as this bird does.

American Robin, Fish Creek Park, Calgary, March  4, 2017.

Robins are of course migratory, but there are always some (a few dozen to a couple hundred) that overwinter in the city. This bird, seen on March 4 with seven others, probably overwintered since it was a little too early for the migrants to return. Unusually, this looks like a female – most overwintering birds are males, trying to get an advantage in getting to breeding grounds earlier. Now, in early April, there are many migrating robins back, but they are almost all males, either passing through or claiming territories here. The females arrive later.

Dark-eyed Junco (Slate-colored subspecies), Calgary, March 4, 2017.

These native sparrows overwinter here in good numbers, and for a few weeks more there will be many migrants passing through. They breed here in the boreal forest and are far more common west of the city and farther north in the summer.

Pine Siskin, Calgary, March 4, 2017.

Siskins usually breed in coniferous forests (including in parts of Calgary), but when not breeding they move erratically around the continent in search of food. They are sometimes here in large numbers in the summer, and sometimes completely absent.

Black-capped Chickadee, Calgary, March 4, 2017.

A resident bird, they are paired up and beginning to nest now.

Finally, here are three shots of the immature Northern Goshawk from Queen’s Park Cemetery.

Northern Goshawk, Queen’s Park Cemetery, Calgary, February 19, 2017.

Goshawks are not common in Calgary but can be seen year-round. However, they breed in high-canopied mixed forests so adults are usually found at higher elevations and farther north in the summer. They are more commonly seen here in the winter.

Furry Friday: Deer of Calgary

I still find deer identification tricky. Let me know if I’ve misidentified any of these!

Furry Friday: Snowshoe Hare

Tony LePrieur photographed this Snowshoe Hare in the Weaselhead Nature Area of Calgary on February 20, 2017.

Snowshoe Hare, Weaselhead, February 20,2017. Photo by Tony LePrieur.

Snowshoe Hares (also called Varying Hares) can be found in the city in wooded areas like the river valleys, Fish Creek Park, the Weaselhead, and Griffith Woods Park. They are smaller and have shorter ears and tails than the common White-tailed Jackrabbits you see in residential neighbourhoods and open fields. Jackrabbits have black-tipped ears and a longer white tail. Snowshoe hares have huge hind feet, as their name indicates.

Although they are usually quite common in places like the Weaselhead, they are secretive during the daytime and are rarely seen. You often see their tracks in the snow when birding in these wooded areas. Snowshoe Hares also blend in to their surroundings very well – the white winter coat you see in this photo will soon turn to a rusty brown to help camouflage it during the summer months.
