More Birds of Bowmont Park

In May we posted some photos taken by Lorraine Glass in Bowmont Park in NW Calgary (see this post). Gord Smith was inspired by these photos to go and see what he could find. Here are his photos from May 22 and May 27, 2017.

Great Gray Owl with Pocket Gopher

Correction: The unfortunate rodent is a Northern Pocket Gopher, not a Meadow Vole. Pocket Gophers are the ones that make mounds of  loose soil above their underground burrows. The soil mounds are commonly seen, but the animals themselves rarely venture above ground. When they do, it is usually at night and they don’t go more than a few feet from the mound. Hence they are rarely seen – this is the first photo of one from the Calgary area that I’ve seen. – Bob Lefebvre

Tony LePrieur got this great shot of a Great Gray Owl with a captured Northern Pocket Gopher recently near Calgary.

Weaselhead Bridge – Ring Road Petition

Posted by Bob Lefebvre

Most Calgary birders are aware by now that the ring road construction adjacent to the Weaselhead Nature Area in SW Calgary is well under way. A huge area has been cleared in preparation for building a bridge over the Elbow River.

This project has been discussed for decades, and birders have been very concerned about building a bridge and highway through such an environmentally sensitive area. I think it has long been assumed that when the time came, if it did, the builders would be sure to follow best environmental practices to minimize the impact on this area. In particular, it was hoped that a clear span bridge like the Stoney Trail bridge over the Bow River would be built. Instead, the plan is to build an earthern berm or cut-and-fill bridge, which will fill in the valley up to the road level for most of the span, essentially forming a dam across the floodplain. This design will have many negative consequences for the birds and other wildlife in the valley, and create a great many problems during flood events.

The Weaselhead Nature Area is on the right, and the ring road construction showing the diversion of the Elbow River on the left. As you can see, there has already been a stunning amount of disturbance, cutting off the Weaselhead from the ecologically diverse Elbow Valley to the west. Photo from the website http://www.yyccares.ca/recent_pictures.

A concerned group of local citizens is petitioning the Alberta Government to build a better bridge over the Elbow. Please visit their web page YYC Cares. There is a great deal of information on their site, and you can sign the petition there.

Birdboy Birdathon

Posted by Bob Lefebvre

In May, Ethan Denton completed his 2017 Great Canadian Birdathon to raise money for bird research and conservation. He was part of a team with Gavin McKinnon, called the Saw-it Owls. Here are just a few photos of birds the team saw on their birdathon.

You can read about Day One of their birdathon on Ethan’s blog, Bird Boy.

The Great Canadian Birdathon (formerly called the Baille Birdathon) is a program of Bird Studies Canada. Participants are sponsored to count as many birds as they can every May. You can contribute to Ethan’s personal donation page here. Gavin McKinnon’s page is here. Please help them to reach their fundraising goals!

Furry Friday: Rodents of Carburn Park

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

Beaver, Carburn Park, May 23, 2017. Photo by Tony LePrieur.

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.

Nature Calgary’s Big Week of Birding

Posted by Bob Lefebvre

For many years Nature Calgary has held a Big Day on the Victoria Day holiday – an attempt to find as many species as possible in one day, in this case all of them inside the Calgary city limits (we had 116 species this year). During the 2015 Calgary Birding Competition we decided to add a Big Day in the Calgary Region–the 80-km diameter circle centred in Calgary. We did the trip again last year. In both cases we saw lots of good birds (151 species in 2015, and 132 in 2016) but it is a long day with quite a few dead stretches of driving.

For this year, we decided to try something new: A Big Week instead of a Big Day in the 80-km circle. There will be a series of field trips offered from June 4 to 10, and we will try to reach a cumulative total of 175 species on these trips.

Most of the trips will be led by myself, Andrew Hart, and Rose Painter. We will kick it off with a day-long trip to the northwest corner of the circle, around Water Valley, on Sunday June 4. The final day will feature another long trip to the south and southwest. Both of these trips require registration because car-pooling will be required and spaces will be limited.

There will also be several field trips offered during the week, including trips inside the city to the Weaselhead and Inglewood Bird Sanctuary. A couple of other trips will be Twitch ‘n’ Tours, our term for for a field trip with a known starting point but for which the destinations are not decided until the last minute, so that we can chase rare birds or ones we have not been able to find so far.

If you want to see how many species you can find in the Calgary region in one week in June, join us for some or all of these outings. See the Nature Calgary field trip page for details and to register.

Migrant Sparrows: White-throated and Chipping

Posted by Bob Lefebvre

More birds from my backyard. The White-throated Sparrows were around for just a couple of days in the first week of May (although I heard one singing in the neighbourhood this morning, possibly a late migrant grounded by the strong winds and rain we had yesterday). Chipping Sparrows passed through last week, and I counted up to thirty in my yard one day, along with a few of the closely-related Clay-colored Sparrows.

The above photo shows the sharply contrasting white throat patch and the yellow lores that are keys to identifying this species. Some White-throated Sparrows have tan and black rather than white and black head stripes, but they should always show the white throat and a least a little yellow on the lores.

The tan and black variation is a colour morph which some White-throated Sparrows have throughout their lives. It is not a juvenile characteristic, like the tan and gray head stripes of the White-crowned Sparrow. All White-crowns have tan stripes as juveniles, and white stripes as adults. Here is an old photo of an adult White-crowned Sparrow. Besides the lack of a white throat and yellow lores, note the clean gray breast and spotted back feathers which are quite different from the White-throated Sparrow. The pale bill (pink or yellow) also stands out.

Below are a few of the Chipping Sparrows that were in my yard. There were thousands in yards all over the city that week.

Both of these species breed in the city. White-throated Sparrows are common in the Weaselhead, the west end of Fish Creek Park, and other parts of the city where the boreal forest intrudes. You can hear their beautiful song there right now. Chipping Sparrows breed throughout the city, even in suburbs in low numbers. Their song is a long, dry, steady trill, which is sometimes mistaken for an insect sound.

Other birds I’ve had pass through my yard recently on migration include White-crowned Sparrows (in pretty low numbers this year) around the end of April and first week of May, Ruby-crowned Kinglet at about the same time, and a Baltimore Oriole briefly on May 21.
