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 Stilt chick.
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.

This looks like a young LeConte’s Sparrow.
And some mammals: North American Beaver…
… and White-tailed Deer fawn.

Tony LePrieur has been generously sharing photos with us every week, and I sometimes get a little behind in posting them. Today I want to catch up a bit by posting several sets of his summer pictures of birds from the Calgary region.
The first set is of young birds and their parents from Fish Creek Provincial Park, taken on July 16.
Juvenile Western Wood-Pewees waiting to be fed.
Western Wood-Pewees, three young with an adult.
I think this is another Western Wood-Pewee.
Eastern Kingbird parent with three juveniles.
Eastern Kingbirds.
I think this is a VERY young Yellow Warbler.
And this Warbling Vireo may be even younger – just fledged!
Judi Willis took these photos of a Great Blue Heron fishing in the Stormwater pond in Votier’s Flats, Fish Creek Park, in early August.
A determined-looking heron looking for food.
Success! A good-sized meal.
Does anyone know what species the fish is? The down-turned mouth suggests a sucker or other bottom-feeder.
Bonus photo: an American White Pelican landing on the water:

Here are some more photographs, taken by Colin Nakahara, of the Swainson’s Hawk and chicks at a nest in SE Calgary. This post from last week showed the downy young in the nest. Today’s photos, taken on July 14, 21, and 29, show the growing chicks. Unfortunately one chick didn’t make it.

July 21. Another week older, and a little closer to leaving the nest.

This one looks just about ready to fly. July 29.

Swainson’s Hawks commonly nest right in the city, but since the nests are high in the treetops it is usually difficult to see the young birds before they fledge. Here are some photos taken from the rooftop of a business in the Highfield industrial area of Calgary. They were sent to me by Mark Dann, and the photographer is Colin Nakahara.

The adult bird is aware of Colin when he is on the roof and keeps an eye on him but has not been threatening or agitated. I hope to post more photos to show the growth of these beautiful birds!
Photos taken by Tony LePrieur on the weekend of June 26, 2016, at Fish Creek park and Bridlewood Wetlands in Calgary, at Frank lake, and in the Priddis area. There are lots of juvenile birds being fed out there right now!

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!

Calling for food from the host Song Sparrow.
Another cowbird being fed by a Western Wood-Pewee, not far from the Song Sparrow and chick at Sikome, Fish Creek Park. This could very well be a biological sibling of the bird being fed by the Song Sparrow.
The Western Wood-Pewee adult, probably a little worn out from trying to provide for the cowbird chick.
Two cowbirds were being fed by a pair of Savannah Sparrows at Frank Lake, also on Canada Day.
A close-up taken from the above photo.
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.
