Angry Birds! (…actually just Brown-headed Cowbird fledglings)

Posted by Bob Lefebvre

Brown-headed Cowbirds are obligate nest parasites, so they do not nest or raise their own young – the female cowbird lays her eggs in a number of nests of other species. If the host birds don’t realize that they are incubating a foreign egg, they will feed the cowbird chick until it fledges and for a while afterwards, until it can forage on its own and rejoin its cowbird cousins.

Many of the songbirds that are parasitized in this way are quite a bit smaller than cowbirds, so it makes for a comical sight when the “parents” are feeding their giant “offspring”. It’s no joke for the host parents, though, as this is a great drain on their food-gathering resources, and it has a negative impact on their ability to raise their own biological young.

Tony LePrieur has recently seen a number of young cowbirds being fed by different hosts in the Calgary area. Thanks to Tony for these fantastic photos!

Those of you with teen-aged boys will know how this Savannah Sparrow feels 🙁

Cowbirds also often parasitize Clay-colored Sparrows and even smaller birds like Yellow Warblers and House Wrens, so if you see any of those species carrying food, watch to see if they are feeding cowbirds.

Backyard Birds: Baltimore Oriole

Posted by Bob Lefebvre

Most birders know that Baltimore Orioles will feed on oranges, but have you ever tried this in your yard? Even if you aren’t near their nesting habitat, you may get one on migration, as I did five years ago.

Below is a re-post of something I posted originally on June 1, 2011. Since then, I haven’t had any more Orioles (and still no Catbirds) in my yard – but I’m still trying!

Oranges for Orioles – originally posted June 1, 2011, by Bob Lefebvre.

For the last couple of years I have been putting out slices of oranges in my yard in the hopes of attracting Baltimore Orioles or Gray Catbirds.  I place the oranges on my tray feeder and in suet cages.  So far this has attracted only ants.  Last Friday morning, I thought that perhaps the heavy rain might force some migrants down, so I put out two fresh orange halves on a flower planter.  Within a half hour of arriving home in the afternoon, I looked out to see this bird feeding on the orange.

This first-year Baltimore Oriole stayed around the yard for two days, feeding on all the oranges, including the ones in the suet cage that I had placed there about two weeks before.

So if you want to see a Baltimore Oriole in your yard, putting out oranges really does work.  Now I’m just waiting for that Catbird.

Rare Backyard Bird: Lesser Goldfinch

Posted By Bob Lefebvre

On May 15, 2016, Linda Vick photographed this bird in her yard in Cochrane. It is a Lesser Goldfinch, a very rare bird for Alberta. This is only the second record ever of this species in Alberta, the first being two years ago.

If I saw this bird in my yard and didn’t look too closely I might think it was an American Goldfinch. Lesser Goldfinches breed in  the SW United States, so I’m sure many of you, like me, are unfamiliar with it. Keep an eye out!

Lesser Goldfinch males have a black cap but can be distinguished from American Goldfinches by the greenish back (sometimes black, but unlike the yellow back of an American Goldfinch), the white at the base of the primaries, and the grey rather than pinkish bill colour. The pictured bird looks like a young male, developing its black cap.

The start of spring in the Weaselhead

Posted by Dan Arndt

Our spring birding sessions started off on a bit of a cooler note than the end of our winter course had been, but even though it was a bit duller and colder, the birds did not disappoint. We repeated our previous outing to the Weaselhead almost exactly, with a visit to North Glenmore Park to scope the reservoir and check on the Great Horned Owls we’d found there in late March.

Weaselhead - 4-3-2016

Weaselhead – April 3, 2016

The feeders seemed a little emptier that week, with most of the Common Redpolls, Pine Grosbeaks, and Pine Siskins having departed, but we did find one lone siskin feeding not at the feeders, but on the budding catkins on the trees bracketing the pathway.

All the way down the hill and onto the bridge we were hard pressed to see anything nearby, with little rhyme or reason. The usual deluge of dog walkers, runners, and cyclists down into the Weaselhead was much diminished due to the weather, and yet the birds were still strangely absent. We crossed over the bridge and off to the deeper parts of the park when we quite nearly stumbled across this little Snowshoe Hare in the shrubs beside the path.

We watched it for a little while while it foraged, seeming not too shy of our presence, but attempting to at least stay a little bit hidden from our direct view. We soon headed off to our usual spot to listen for Boreal Chickadees when we were stopped dead in our tracks by the distant sound of a Ruffed Grouse drumming.

I’d been searching for this particular bird for quite a while, as I had found a few drumming logs that he had been displaying on recently on my last solo trip down here. Drumming logs can generally be identified by numerous piles of grouse scat on them, often around an area on the log where the bark has been stripped away. We caught sight of him about a forty meters away, and paused to let him get comfortable with our presence. Sure enough, when he was calm enough, he began his display once again.

Once we were satisfied that we’d all had a good view of his displays, we moved on and let him get back to wooing his grousettes (I’m sure that’s the technical term for it… or maybe it’s hens? I’ll stick with grousettes.) Again, the trees were quiet, and the activity was at a bit of a lull, but as birding often goes, sometimes its those quiet days that give the best experiences!

We did manage to catch a flock of Trumpeter Swans flying west off the Glenmore Reservoir just as we entered a clearing. Lucky for us!

Back to the bridge we went again, and sure enough, our little Snowshoe Hare friend was feeding on the edge of the creek, this time a little bit bolder!

Since we had a few things to check out up at the top of the hill, we decided to bee-line it back to the parking lot to check out the ponds at North Glenmore Park. Along the way though, we did find a couple little highlights to the day.

This Red Squirrel was caught red-pawed at the exact same feeder we had seen a Least Chipmunk feeding from just a few weeks prior. It seems this bird feeder is the preferred site for rodent sightings!

Near the top of the hill, we also came across this American Robin singing away from near the top of a budding aspen.

Back at North Glenmore Park, we found the proud papa Great Horned Owl resting peacefully with his mate nearby. No babies were visible yet, but soon enough those eggs would hatch and become some of the most adorable little fluff balls you’d ever see!

And finally we took a few minutes to scan the Glenmore Reservoir, and boy was I glad we did! Far out on the reservoir one of the common perches for gulls and swallows were four species of gulls, and one of those was our first of the year. Lined up nicely were a California Gull (far left), a couple of Ring-billed Gulls, a Franklin’s Gull, and on the far right was a Herring Gull. It’s too bad these guys were so far off, because they sure were a nice sight to see after our slow day!

The end of Winter in the Weaselhead and North Glenmore Park

Posted by Dan Arndt

For our last outing for our Friends of Fish Creek Winter Birding group, we headed to the Weaselhead and North Glenmore Park to see what winter birds remained, and if any spring migrants had shown up around the Glenmore Reservoir and in the Weaselhead itself. While many of our winter birds had already left, a few die-hards were still around in good numbers, and we definitely were not disappointed with the numbers of spring birds we found all around the park.

Weaselhead - March 20, 2016

Weaselhead – March 20, 2016

We headed down into the Weaselhead first thing, checking the feeders along the way. I had headed down before our group to fill some of the feeders, and managed to spot an overwintering American Goldfinch, but when the rest of our group headed down as a whole all of the feeders were completely devoid of activity. Part of the reason for the vacancy is that now that the weather has turned, the birds were not quite as reliant on the feeders as insects had begun to hatch, and caches stored during the winter would provide plenty of food. We did have one little fellow who turned up, as always, at the tail end of the winter session.

Least Chipmunk

Fresh from his winter hibernation, this Least Chipmunk seemed completely oblivious to our presence as he stuffed his face full of black-oil sunflower, peanuts, and various other seeds I’d placed at the feeder earlier in the morning. I just love how much character these little mammals have, and how single-minded they can be when they first wake up.

While she wasn’t right at the feeder, this Hairy Woodpecker was hanging out nearby, hammering a hole in the side of this tree to pick out a tasty meal.

male House Sparrow

A little further down the path and across the bridge we found this male House Sparrow and his mate picking out some twigs, grass and leaves to make their nest for the coming season. Given where they were loafing about, they may have even been considering setting up shop in one of the Cliff Swallow nests on the bridge!

American Tree Sparrow

Before we turned around to head back up the hill, we stopped and checked the logs and information signs that have been used all winter as a feeding station, and sure enough we found some American Tree Sparrows singing away in the brush, and coming out to feed. These little sparrows have an amazing song, and are just as striking to look at.

American Wigeon

We headed back up the hill and off to the east end of the Glenmore Reservoir to find our returning migrants, and were not disappointed on the first pond. A pair of American Wigeon were floating along the back end of the pond, well away from the Canada Geese and Mallards who were clearly set up on their nesting territories closer in.

While we were scanning the ponds for waterfowl, sparrows, and anything else we could find, we heard a flock of late White-winged Crossbills in the spruce trees to the north, picking through the few remaining cones that had made it through the winter. Both males and females were in fine form, with the majority of the birds being immature, and as always, seemed to be completely oblivious to our presence.

These Canada Geese seemed to have their feathers ruffled by the Mallards (in the shade of the rock on the left). It wasn’t until the Mallards had simply had enough and moved on that the geese left them alone. Seeing these inter-species interactions is always a treat, and late winter and early spring can lead to some great opportunities for this behaviour.

Great Horned Owl

Our best surprise of the day was coming across this male Great Horned Owl high up in a spruce trying to have a nap… until we disturbed him. He wasn’t pleased to see us. At all.

These Common Goldeneye (and a very confused Mallard) were still trying to display for the few remaining single females, though most others of their kind we’d found this late in the winter/spring season. Despite that, at least two of them seemed to making a positive impression!

Dark-eyed Junco

[exif id=”15453″]

One of our last birds of the day, and a great one at that, was this Dark-eyed Junco of the Oregon subspecies that sang a bit for us, but also perched high up in the nearby bushes and allowed everyone very good looks.

The spring course with the Friends of Fish Creek is now well under way, so expect some new posts in the next few weeks from our more recent outings. Have a great week, and good birding!
