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!

Two cowbirds were being fed by a pair of Savannah Sparrows at Frank Lake, also on Canada Day.

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.

Rare Backyard Bird: Lesser Goldfinch

May26

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.

Fish Creek Provincial Park HQ and Sikome Lake – Spring on the horizon

Mar21

Posted by Dan Arndt

Our outing on February 28 took us to the area surrounding Fish Creek Provincial Park’s headquarters and administration building, and then down near Sikome Lake. Our main goal was to find two pairs of resident Great Horned Owls, but also to check some of the ponds and the river for newly arrived waterfowl, and we weren’t disappointed!

Fish Creek Provincial Park HQ – February 28, 2016

Great Horned Owl (male)

[exif id=”15402″]

Our brief walk around the headquarters led us to flush a male Great Horned Owl from the spruce trees, where he perched right out in the sun on some low willows. This is likely the male from the pair that roost here all winter long, and his mate is certainly somewhere nearby!

White-tailed Jackrabbit

[exif id=”15403″]

We headed down the pathway to the west with little to see or hear, and on our return trip we headed over to the brush near where the owl had flushed to only to find a pair of White-tailed Jackrabbits doing their best to stay completely still. They’ve had a rough winter staying camouflaged, with very little snow for much of the season, and now that they’re starting to turn brown, the snow we’ll be getting with our usual spring squalls will be just as difficult on them.

Sikome Lake area – February 28, 2016

After parking near the boat launch and checking the river, we turned up next to nothing nearby. The well above seasonal temperatures had boaters and fishermen up and down the river long before we arrived, so much of the waterfowl had already flown off.

Black-capped Chickadee

[exif id=”15404″]

[exif id=”15405″]

Leave it to the chickadees and nuthatches to brighten up the day! As we crossed the road to take a closer look for another well known pair of owls, we found a small mixed flock of birds foraging in the low brush, and they were more than happy to pose nicely for us all to get a good look at them.

European Starlings

[exif id=”15410″]

While there are often a few European Starlings that can be found in this area all winter long, there were nearly thirty of them inspecting cavities, calling, and doing their best impersonations of Red-tailed Hawks, Sora, Killdeer, and a number of other birds all morning long.

Great Horned Owl

[exif id=”15408″]

We found the new mate of the female Great Horned Owl guarding the nest in a little more open area than her past mate usually sat, but I have no doubt that he’s got just as good an eye on mom and the eggs. Given that this was three weeks ago, it won’t be much more than another week or two before they begin to hatch.

[exif id=”15407″]

You can barely see her in the corner of the nest here, but that’s just their natural camouflage at work!

Canada Geese on nest

[exif id=”15411″]

It wasn’t just the Great Horned Owls who had decided it was time to get on their nest! This pair of Canada Geese were nesting nearby in a hollowed out tree top that these, or other Canada Geese use every year without fail. It’s always weird to see them nesting so high up, but they know what they’ve been doing it for years!

Downy Woodpecker with dilute plumage

[exif id=”15409″]

A couple of the flight feathers of this female Downy Woodpecker that look brown rather than the usual black. This type of plumage variation is known as “dilute plumage”, which is different from both albinism and leucism in that it’s simply a reduction in the normal amount of melanin that is expressed, rather than an entire lack of it. She had been seen there the entire week leading up to our outing, and it looks like she’ll be breeding nearby. It’ll be interesting to see if her offspring have similar plumage as she does!

Cackling (left) and Canada Geese (right)

[exif id=”15412″]

With the Canada Geese getting on nests, and actively feeding on the fresh grass shoots all throughout the park, there were huge numbers of them around the edge of Sikome Lake. Whenever there are large numbers of Canada Geese around, it’s always worthwhile to try to scan for Cackling Geese, and we managed to find at least one that day. The bird on the far left has that diagnostic short, triangular bill, very tiny head, short neck, and was much smaller overall than the nearby Canada Geese.

Common Goldeneye

[exif id=”15413″]

These Common Goldeneye were happily paired up in the storm water ponds south of Sikome Lake, and were keeping a sharp eye on us as we watched them. Their numbers have diminished a little bit right along the river, but as more and more small water bodies open up, pairs of them will start showing up at each little pond and slough throughout the province.

Green-winged Teal

[exif id=”15414″]

Green-winged Teal

[exif id=”15415″]

There were also a pair of male Green-winged Teal who had also showed up on the small ponds and sat quite nicely for us to watch, and we got very good looks at their beautiful greens, browns and grays in their breeding plumage.

Bufflehead

[exif id=”15416″]

Our last new birds of the day was this pair of Bufflehead, and it seemed that the female of this pair was chasing around her mate, a bit of a role reversal to the usual situation, but they’re always nice to see in the late winter, as they also disperse throughout the prairie potholes to breed and raise their young.

Next week, we’ll cover our outing on March 6 to Mallard Point, with our first gulls of the new year!

Have a great week, and good birding!

Spring Birding Course 2016

Mar5

The Friends of Fish Creek Provincial Park Society is now taking registrations for its popular Spring Birding Course. This 12-week course starts March 28 and runs until the end of June. You can choose to go out one or two days per week. Field trips, which take place in a variety of parks throughout the city, last 2.5 to 3 hours.

Fall Birding Course Begins – Carburn Park

Oct9

Posted by Bob Lefebvre

The Friends of Fish Creek Provincial Park Society Fall birding course began again on August 31, 2015. Many of our readers look forward to Dan Arndt’s posts every Monday with a narrative of the previous week’s outing accompanied by his outstanding photos of some of the birds seen. As usual Dan is scheduled to lead the Sunday morning group, one of the fifteen weekly outings that are needed to accommodate the 196 registered participants. However, work commitments will keep Dan away for many of the fall outings. With the help of Rose Painter and George Best, I will fill in for him when he is away.

I don’t usually carry a camera when helping to lead a group, but George does, and he is an excellent photographer as many of you know. I will try to summarize our walks and illustrate them with George’s photos.

For the first week of the course we went to Carburn Park, which had been a great spot for fall warblers in the weeks leading up to the start of the course. Many of the earlier-migrating species had more or less finished passing through Calgary by the beginning of September, but we hoped to see quite a few Wilson’s, Yellow-rumped, and Orange-crowned Warblers on our outing on September 6.

Carburn September 6

Carburn Park walk, 6 September 2015.

We did see about 30 Yellow-rumped and possibly one Yellow Warbler, but none of the other warbler species. However, we did see huge numbers of birds of the river, including the largest concentrations of Common Mergansers and Double-crested Cormorants that many of had ever seen. (All photos by George Best.)

Mergansers

A few Common Mergansers (55 by my count) and two Canada Geese.

Cormorant in tree

We counted about 100 mergansers and 150 cormorants on the day. Most of them were concentrated at the north end of the park, just south of the Glenmore Trail Bridge over the Bow. This is the area that used to be the northernmost pond in Carburn park, before the flood of 2013 turned it into a major river channel, gravel bars, and an island. It is usually a very birdy part of the river.

Cormorant on Branch

Double-crested Cormorants resting on a partially-submerged tree in what used to be the north pond at Carburn Park. The birds with light breasts are juveniles, hatched this year.

Cormorant

We also saw about 65 American White Pelicans in this area. They no longer go to the old weir in Pearce Estate to feed, and Carburn Park is about as far upriver as the big groups usually go. (The Sunday afternoon FFCPP group counted 106 pelicans that day, and an incredible 225 Common Mergansers!)

Other highlights in Carburn Park in September are the usually-reliable Wood Ducks, often seen in the quiet channel between the big island and the river shore in the central part of the park, and raptors like Bald Eagles, Osprey, and Swainson’s Hawks. We saw three of each that day, as well as this Merlin:

We counted 38 species of birds for the day, and three mammal species: the usual White-tailed Deer and Eastern Gray Squirrels, and a less-commonly-seen American Mink.

Next post: In week two of the course we returned to the Inglewood Bird Sanctuary for the first time in over two years.

Autumn Birding Course 2015

Jul25

The Friends of Fish Creek Autumn Birding Course will be starting up on August 31. You now have the option of signing up for either one outing a week or two. Youths accompanied by a registered adult can attend the whole 15-week course (over 40 hours in the field) for only $5. These outings are a lot of fun and are great for beginners, and for anyone wanting to explore Calgary’s natural areas.

Go to the Friends of Fish Creek site to register.

The Beautiful Birds of Bowmont

Jun8

Posted by Dan Arndt

Two weeks ago our group visited Bowmont Park, one of the few parks we often visit in the northwest quadrant of Calgary with the Friends of Fish Creek birding courses. It’s a bit of a special park, as it borders on the Bow River, but also a gravel quarry which is home to a pair of Osprey in the summer, a few small ponds, and a south facing slope allowing for a wide variety of songbirds.

Bowmont Park – May 24, 2015

This was the first week of outings where Yellow Warblers were the most visible. All spring and summer long, these little yellow fireballs will be singing all over the place until they manage to find a mate and raise their young. They’re really quite fun little guys to watch, and it’s always nice when they’re so easy to photograph, like they were that morning!

I mentioned the Osprey nest earlier, and this is one area where Enmax has set up an Osprey platform to prevent the Osprey from nesting inside the gravel quarry on the power lines. When we rounded the corner to check out the nest, we were greeted to this sight:

Canada Goose

The platform had been taken over by a family of Canada Geese, but thankfully the Osprey had found another location to nest nearby. We walked over to the river a little before coming out underneath the Osprey nest, and found this Tree Swallow picking up nesting material right off the pathway.

On our way out to the main pathway, we spotted this Clay-colored Sparrow finishing up his shift at the gravel quarry and heading out for the day. They’re such industrious little workers! This was just after 8:00 in the morning and already he’d put in a full day of work.

Speaking of hard workers, this Osprey was taking trips to and from the new nest all morning, each time taking more and more branches in to build up the nest to an appropriate size, wedging them into the nest each time.

The pond at the back of the quarry which is usually unbelievably productive turned up next to nothing for us. It seemed rather unusual, so we headed further up the north slope, and found this perched Swainson’s Hawk waiting for us up there.

While we had some good looks at a few birds on the northwest hill, we had much better looks at them a bit later on, but thankfully we did manage to get a nice close look at a Northern Rough-winged Swallow on the river near the pathway on our way back. These birds can be somewhat hard to find around the city, but often along the Bow River.

We gave the pond a second chance to redeem itself, but sadly it was just as empty as it had been on our first visit, so we walked along the back end of the quarry and were treated to another great view of a male Yellow Warbler singing his heart out.

Our last good bird of the day was a lone Gray Catbird, of which we had seen a few earlier in the day but at a bit further distance. This beautifully drab bird was singing his heart out over and over again from the aspens and willows nearby. The cinnamon undertail and jet black cap are the only real splashes of color on these birds, but their song is unmistakable.

And that was another great week of birding. Have yourself a wonderful week, and good birding!

Sparrows, waterfowl, and warblers at South Glenmore Park

May18

Posted by Dan Arndt

Our outing on May 3 took us to South Glenmore Park. Following our second week at Carburn Park, I headed over to the Glenmore Reservoir to try to find some water birds, and was able to get a couple photos of a distant female Red-breasted Merganser and White-winged Scoter, spurring on the visits for the following week. While we didn’t get either of them on our official outing, we did get a whole bunch of other great spring migrants, and had an amazing time finding all the new birds.

For the past few years, a family of Common Ravens has nested right near the parking lot. Apparently this adult Raven has decided that peanut butter is a perfect breakfast treat. I like his thinking.

As we walked around the point, we found Red-necked, Western, and Horned Grebes but sadly we couldn’t pick out a single Clark’s among over 75 Western Grebes. At least we had a couple Horned Grebes that were willing to let us get close.

Horned Grebe

The view from the top of the hill above the main pathway allowed us to get even better looks at some of the Western Grebes out on the reservoir.

In the trees along the ridge there were Tree Swallows and Northern Rough-winged Swallows hawking for insects above the canopy, but the most numerous songbird of the day was the Yellow-rumped Warbler. Along this stretch, there must have been at least 20 of them!

Yellow-rumped Warbler

Another new bird of the season was the Savannah Sparrow. This one seems to have a little less yellow in the lores than I’m used to, but his song was unmistakable!

We then circled out to the west through the boreal and aspen parkland areas on the west end of the park, but came up with very little. We didn’t even see a single Common Loon on the entire reservoir that day, I think mostly because of how open the water was, and how many water bodies outside of the city were open after such a mild winter.

On our way back to the parking lot, we did have a close fly-by of this Swainson’s Hawk, one of our first ones of the season for the Sunday morning group!

As we returned to the parking lot, I decided that we hadn’t really had much luck with the sparrows on the pond, so sat in the grass and waited for them to pop out. I was welcomed very shortly after by both a White-crowned Sparrow as well as a Lincoln’s Sparrow. Well worth the effort!

Carburn Park, Part 1 – South of the Sue Higgins Bridge

Apr27

Posted by Dan Arndt

Our walk last week took us to Carburn Park once again. We actually headed there this week as well, so I’ll cover the birds we found on the south end of the park this week, and the north end in next week’s post.

Carburn Park – April 19, 2015

The Sue Higgins Bridge south of the parking lot in Carburn Park is a regular roost (and nesting location) for any number of Rock Pigeons, and you can usually find at least a few here. It was really nice to find this rather beautifully colored bird, and in great light to show off some of the iridescence on the neck.

Rock Pigeon

On the gravel bar just south of the bridge were over a hundred Franklin’s Gulls, and also a few Ring-billed Gulls flying by eating the freshly hatched insects flying up from the river. One of the advantages of being out so early is that the insects aren’t too high up, and neither are the gulls and swallows yet either.

Ring-billed Gull
Pentax K-5 + Sigma 150-500@500mm
1/1000sec., ƒ/8.0, ISO 500

Did I say swallows? Yes indeed, the Tree Swallows have really started showing up in big numbers too, and we had flocks overhead almost the whole time, wheeling and darting around and getting their fill of hatching mayflies and midges.

Tree Swallow
Pentax K-5 + Sigma 150-500@500mm

We followed the river edge south and came across some interesting sights, as well as the real first returning migrant Song Sparrows. We also found lots of American Robins foraging about, posing, and searching for nesting materials in preparation of the coming breeding season.

One of the most amazing finds last week was a group of four Wood Ducks perched high up in a tree, set exactly at the wrong angle for our approach. By the time I got around to have the light in at least a little bit of a helpful angle, three of them had moved into hiding, but at least I got this lone female! Yes, Wood Ducks are tree nesting ducks. How crazy is that? They’re one of the few ducks that have strong feet and claws capable of gripping branches and bark.

At the far south end of our walk we found another large group of Franklin’s Gulls, many showing quite a bit of pink in the breast and bright red bills typical of fresh breeding plumage. Their raucous cacophony followed us all throughout the park these past two weeks, often drowning out some of the more subtle songs and chip notes of other returning birds, but it is really great to have these birds back!

Franklin’s Gull
Pentax K-5 + Sigma 150-500@500mm

On our way back we came across a couple of active nests as well, one containing a pair of Northern Flickers (and presumably their eggs), as well as a Black-billed Magpie nest, with either mom or dad standing guard and keeping a sharp eye on us.

So that was another week with the Friends of Fish Creek. Next week we’ll see how the north end of the park treated us!

Have a great week, and good birding!

Spring Birding Course 2015
