Online Film – Avian Summer

Jul19

Posted by Bob Lefebvre

Photographer and filmmaker Rick Andrews has produced a wonderful wildlife documentary about some of our local birds. Avian Summer has fantastic high-resolution video of birds that migrate into Southern Alberta each spring, where they come to find a mate and raise the next generation, before migrating south again in the fall. Watch the trailer below.

Avian Summer by Rick Andrews – trailer.

The full film is available to rent or purchase on the Vimeo platform. The cost is $8 for a three-day rental, and $25 to buy. You can watch it on your phone, tablet, or computer. (I played it on my phone and streamed it to our TV, and it looked fantastic.) Proceeds from Avian Summer will benefit the Growing the Grassroots Endowment Fund in support of nature-based interpretive programming at the Helen Schuler Nature Centre in Lethbridge.

I really enjoyed this thirty-seven minute film. It focuses mostly on waterfowl, raptors, herons, and cranes, and a few songbirds. There are a lot of great sequences of birds raising their young.

Rick Andrews is a conservation wildlife photographer and filmmaker from Southern Alberta. He has many other excellent films available for free on Vimeo, so be sure to check them out. (It is free to sign up on Vimeo.) Rick’s collection of films showcases resident wildlife in Southern Alberta, including the full-length documentary Wildlife of the Oldman River Valley (2018), as well as several documentary shorts including Great Horned Owls (2020), Country Club Marmots (2019), and Lethbridge Wild Turkeys (2018).

Here is the poster from the film’s online premier, which was on June 25. The question & answer session with Rick is available to view on the Helen Schuler Nature Center Facebook page here.

Tree Swallows Leaving a Backyard Nest

Jul8

Posted by Bob Lefebvre

Beryl Isaacs has been watching a pair of Tree Swallows that nested in McKenzie Lake in SE Calgary. The nest hole was in an old  post in her neighbour’s yard. All photos by Beryl Isaacs.

There were four baby Tree Swallows in the nest on July 4, 2018.

As the swallows fledged, one begged for food from the House Sparrow.

The House Sparrow attacked the young swallow, but no damage was done.

The House Sparrow, judging by its plumage and the yellow gape at the corner of its mouth, is a recently fledged bird itself. Adult House Sparrows sometimes kill young birds of other species if they get the chance.

Beryl was lucky to see Tree Swallows successfully nest in the city. Since House Sparrows and Tree Swallows are about the same size, they use the same size of nest holes. Aggressive House Sparrows usually harass Tree Swallows that try to nest in backyard boxes or nest holes. Tree Swallows are far more successful when nesting in city parks or outside the city, away from House Sparrows, which are almost always found near human structures.

By the end of the day the young swallows had all fledged and were not seen again at the nest.

Wild Bird Store Event – 20th Anniversary and Grand Re-opening

Oct19

Posted by Bob Lefebvre

The Wild Bird Store is one of the few places in Calgary where you can buy good quality bird seed, feeders, and houses, and the only store that specializes in products for birders. Recently they have moved to a new location, and this Saturday, October 21, they will have an all-day 20th anniversary and grand re-opening event at their new location, 5901-3 Street SE (on 58 Avenue, three blocks west of Blackfoot Trail).

Besides the savings for backyard birders, there will be several interesting presentations throughout the day that should interest all local birders: Chris Fisher’s All-Star Critters, Myrna Pearman on Bird Feeding Behavior, and Gus Yaki on Attracting Birds to Your Backyard. At the end, Gus will also do a presentation on the ten-day walk he led this spring from the Saskatchewan border to Writing-On-Stone Provincial park.

The Calgary Wildlife Rehabilitation Society will also be there (with live birds of prey), as will the Alberta Institute for Wildlife Conservation. So there will be plenty going on to interest birders of all ages!

The new Wild Bird Store is located at 5901-3 Street SE.

Cowbird and Yellow Warbler

Jul18

Tony LePrieur took these great photos of a huge Brown-headed Cowbird fledgling being fed by its foster parent, a male Yellow Warbler.

The warbler is off to find more food for its demanding foster child.

Brown-headed Cowbirds lay their eggs in other birds’ nests and often the other species does not recognize the difference and raises the young cowbird. For more photos of cowbirds with some other host species see these posts:

Peregrines at the U of C: An Update

May10

Posted by Bob Lefebvre

In this recent post about local bird nest cameras, I mentioned that the camera at the Peregrine Falcon nest at the University of Calgary was no longer available online, and that most of the historical data was no longer available either. I have been told by the Media Relations department at the U of C that the decision to remove support was not a budget issue (as I stated), but a resource one. Libraries and Cultural Resources at the U of C are now working with Alberta Conservation Association and Biological Sciences (UCalgary) to partner and take over the project.

The good news is that the historical data about the Peregrines nesting at the U of C has been permanently archived and is available online at this link. We will have a link on our right-hand sidebar under “Calgary Nest Cameras” also.

The bad news is that the Peregrines did not return to nest at the U of C this year. The nest camera continues to be monitored by U of C staff, and if they return the camera link will be restored. (This page would have a link to the camera feed if it was live.) But since the birds are usually back here by the end of March, if they are not here yet, they are not coming. Either something happened to one of the adults, or they are nesting elsewhere.

If you know of any Peregrine Falcons nesting in Calgary, either at the Foothills Hospital, Downtown, or elsewhere, please leave a comment.

Brown Thrasher

May4

Posted by Bob Lefebvre

Brown Thrashers are rather late migrants, usually arriving in the Calgary area in mid-May or even late May, as do their Gray Catbird cousins. The bird shown here was one that actually overwintered here this year. It was first noticed before Christmas 2016 in Airdrie by Heinrich Lohmann.

The bird was coming to a feeder in Heinrich’s yard and continued to do so into March of this year. The photo below was taken on March 10th, and the bird was last seen on March 11th. It may have moved on to its summer territory then, getting a big jump on its migratory rivals (although if so, it will have a bit of wait for any females to arrive back).

It’s not unheard-of for Brown Thrashers to overwinter in Alberta. One was seen in Calgary in December 2015 and (I believe) one in Canmore later that winter. One was seen north of Edmonton in February 2015. Of course, these birds are at high risk when spending the winter so far north. Their normal winter range is in the SE United States. As I said, a bird that successfully overwinters here will get first choice of breeding territories. But it’s also possible that birds that overwinter are only doing so because they were sick or injured during the migration period, and were unable to head south.

In any case it’s always interesting to see a “summer” bird here in mid-winter.

Bird’s-Eye View of Local Nesting Birds

Apr21

Posted by Bob Lefebvre

It’s always fun during breeding season to watch live video of nesting birds from nest cameras around the world. There are some local ones that we provide links to each spring. The links given below are always also visible on our right-hand sidebar.

Calgary Zoo Osprey Nest Cam: This camera has been operating for many years. This year, the nest platform and camera were moved a bit downstream from its usual location, but the Ospreys are back and refurbishing the nest right now.

An April 18th still from the nest camera. From the Twitter feed of boooneill (@ koniell57).

Gray Jay Nest at Ellis Bird Farm: This was the first ever live view of a Gray Jay nest, so this one, operated by the Ellis Bird Farm north of Red Deer, attracted a lot of attention. Unfortunately the nest recently failed. There are still some videos at the link. If the birds re-nest this year and it can be located, new video may be available. The nest was located about 100 km north of Calgary. Information about this and other cameras operated by the Ellis Bird Farm can be found on their website here.

___________________________________________________________

Please note the following correction to the three italicized paragraphs below, about the Peregrine Falcons at the University of Calgary (added May 10, 2017):

According to Drew Scherban, the Acting Manager of Media Relations for the U of C, the removal of the web pages was a resources issue, not a budget one. Libraries and Cultural Resources  are now working with Alberta Conservation Association and Biological Sciences (UCalgary) to partner and take over the project. The historical observations of the Peregrine Falcons have been permanently archived and are available on this page, which we will also link to on our right-hand sidebar.

Unfortunately, there is not a live stream of the nest site right now, because the falcons did not return this year. Staff will continue to monitor the camera feed and if the birds appear they will put it up on this page.

Since the birds usually arrive back here in late March or early April, I think it’s safe to say they will not be returning to the U of C this year. One or more of the adults may have died, or they have found another spot to nest.

___________________________________________________________

Here are the original three paragraphs at the end of this post:

Normally we have a link to the popular University of Calgary Peregrine Falcon nest camera, but this year, the camera is no longer online. In addition, the recent pages with all of the observations from 2010 on have been removed. All that is left online are the historical observations from 1995-2009, so we have a link to that.

I have tried to find out more about this, but haven’t heard back from anyone about who operated the camera or if the link will ever be restored. But the web page was maintained through the U of C’s library and and cultural resources, and they have decided to remove that support as part of their 2017-2018 budget cuts.

The university prides itself on its community outreach, so it’s a shame that they decided to cut this. Perhaps if they got feedback from people who valued the project they would reconsider; if not this year, then next. You can contact the Community Engagement Team on this page, or Thomas Hickerson, Vice-Provost (Libraries) here.

Please leave a comment here if you have any information about this camera or any others in the Calgary area. In 2016 there was a nesting box installed at the top of the Foothills Hospital in the hopes of attracting more Peregrines, but again, I haven’t been able to find out if there is a nest camera or website this year, or if any birds are nesting there.

Battling Bluebirds

Apr15

Tony LePrieur photographed these two male Mountain Bluebirds having a bit of a tussle near Priddis, SW of Calgary, on April 8.

The birds may have been battling over a good territory. Many bluebirds are back in the area now, but some of the females have not yet returned. Primarily an insect-eater, Mountain Bluebirds can get into real trouble when we get heavy snowfalls (like we’re having tonight), especially if it stays cold for an extended period. They will also eat berries.

One bluebird gets the upper hand!

The victorious male. Both birds were OK, but only one gets the territory.
