Backyard Birds: White-throated Sparrow

Posted by Bob Lefebvre

White-throated Sparrows are a common summer bird of the boreal forest, and in Calgary you can see them and hear their beautiful song in places like the Weaselhead and the west end of Fish Creek Park, where they breed. Their wintering grounds are in the eastern and southern United States and on the west coast from Washington to California, a long way from Calgary. Nevertheless, it isn’t unusual for a few to overwinter here, and if you feed birds in your yard they will come looking for seeds. I have had one coming to my yard all winter. Gus Yaki has also had one in his yard all winter, and a couple of others have been reported around the city.

I first saw this bird in November 2017, feeding with a small flock of Dark-eyed Juncos. I have seen it periodically up to as recently as March 2018. It is always with Dark-eyed Juncos, another native sparrow species (the two sometimes interbreed and produce infertile offspring). These native sparrows prefer to feed on a flat surface like a tray, or on the ground.

The distinguishing features of the White-throated Sparrow include the white throat which has a sharply defined lower border, the yellow lores (the spot in front of the eye), and the alternating dark and light head stripes. In this individual, an adult, the stripes are black and white. First-year birds have tan and brown head stripes, and there is also another adult colour morph which has tan and brown head stripes. The two adult colour morphs occur in roughly equal numbers. Interestingly, each adult almost always mates with the opposite colour morph, so both traits persist.

In the above photo you can see the rufous colour in the wing of the White-throated Sparrow and the blurry streaks on the sides of the breast.

Sometimes a White-throated Sparrow will be feeding on the ground with a flock of House Sparrows. Even without binoculars you can usually pick them out by their feeding behavior. Like other native sparrows (the Dark-eyed Juncos and Lincoln’s Sparrows, for example) they tend to scratch for seeds with both feet simultaneously, jumping quickly ahead and back. House Sparrows (which are not native sparrows but an introduced European species) never do this. The White-throated Sparrow also has a longer tail than the House Sparrow.

Here is the song to listen for in the spring:

Late Winter Birds

Apr1

Posted by Bob Lefebvre

It’s spring on the calendar and new migrants are arriving daily. Some of our winter birds have departed, and some of our resident birds are beginning to nest. Here are some photos of birds of late winter in Calgary. All photos by Tony LePrieur.

Bohemian Waxwing, Calgary, February 19, 2017.

Bohemian Waxwings are only here in the winter. Since mid-March only small flocks have been reported. Most have departed to the north and to higher elevations. By the end of April they all will be gone.

Mountain Chickadee, Weaselhead, Calgary, March 12, 2017.

Mountain Chickadees are only occasionally seen inside the city, and most often in the west end where the boreal forest creeps in. This winter there were several seen in the Weaselhead and in Fish Creek Park. They are usually absent in the summer, as they breed west of the city.

Pine Grosbeak (female), Calgary, February 19, 2017.

Pine Grosbeak are one of our winter finches and they were here in low numbers this winter. They move to higher elevations and to the north in the summer.

Downy Woodpecker, Weaselhead, Calgary, March 12, 2017.

Downys are one of our resident woodpeckers and they have been paired up for at least a month, and are now beginning to nest.

Northern Flicker (male intergrade Yellow-shafted/Red-shafted), Calgary, February 19, 2017.

Northern Flickers are also woodpeckers, but are migratory. However, many overwinter here, which may include local birds or ones from farther north. They are currently pairing up for nesting, and it is common to hear their calls and drumming (they often drum on metal chimneys or street lights).

Most of the local flickers are intergrades of the two subspecies (Red-shafted and Yellow-shafted) and they often show mixed field marks, as this bird does.

American Robin, Fish Creek Park, Calgary, March 4, 2017.

Robins are of course migratory, but there are always some (a few dozen to a couple hundred) that overwinter in the city. This bird, seen on March 4 with seven others, probably overwintered since it was a little too early for the migrants to return. Unusually, this looks like a female – most overwintering birds are males, trying to get an advantage in getting to breeding grounds earlier. Now, in early April, there are many migrating robins back, but they are almost all males, either passing through or claiming territories here. The females arrive later.

Dark-eyed Junco (Slate-colored subspecies), Calgary, March 4, 2017.

These native sparrows overwinter here in good numbers, and for a few weeks more there will be many migrants passing through. They breed here in the boreal forest and are far more common west of the city and farther north in the summer.

Pine Siskin, Calgary, March 4, 2017.

Siskins usually breed in coniferous forests (including in parts of Calgary), but when not breeding they move erratically around the continent in search of food. They are sometimes here in large numbers in the summer, and sometimes completely absent.

Black-capped Chickadee, Calgary, March 4, 2017.

A resident bird, they are paired up and beginning to nest now.

Finally, here are three shots of the immature Northern Goshawk from Queen’s Park Cemetery.

Northern Goshawk, Queen’s Park Cemetery, Calgary, February 12, 2017.

Northern Goshawk, Queen’s Park Cemetery, Calgary, February 19, 2017.

Goshawks are not common in Calgary but can be seen year-round. However, they breed in high-canopied mixed forests so adults are usually found at higher elevations and farther north in the summer. They are more commonly seen here in the winter.

Birding Locations: Queen’s Park Cemetery

Feb4

Posted by Bob Lefebvre

One of the smaller and perhaps underappreciated birding locations in Calgary is Queen’s Park Cemetery, located just northwest of Confederation Park near 4th Street and 40 Avenue NW.

Queen’s Park Cemetery.

The cemetery contains a great number of spruce trees, so it attracts many of the species that prefer to feed in or on those trees, such as the winter finches. Many other species of birds and mammals can also be found there, due to the presence of a creek which stays open year-round. The creek runs along the north end, and is bordered by the thickest growth of trees in the cemetery, both coniferous and deciduous.

Detail, north end of Queen’s Park Cemetery, showing the trees which border the creek.

Within the cemetery parking is limited, and it is best to park outside and walk in, or pull completely off one of the roads to park while allowing other vehicles room to pass. Stay away from funeral processions and ceremonies, of course.

The best birding tends to be where the trees are thickest, though you can find Black-capped Chickadees and Red-Breasted Nuthatches wherever there are trees. Crossbills also tend to move around the park (and into the surrounding neighbourhoods). In some years, Brown Creepers and Golden-crowned Kinglets are very common. A stroll along the roads can usually turn up a few of these in the winter.

Golden-crowned Kinglet, November 1, 2015.

Black-capped Chickadee, November 1, 2015.

The water that flows through the north end draws many birds to drink, feed, and bathe.

Sharp-shinned Hawk, January 15, 2017.

Another Sharp-shinned Hawk (or the same one from ten months before?), March 6, 2016.

Queen’s Park is one of the best places to find crossbills. This year there are few in the city, but White-winged Crossbills have been reported there recently.

Black-billed Magpie and Great Horned Owl, October 25, 2015.

This may be the same young Northern Goshawk as in the first photo, taken a week earlier, January 22, 2017.

Queen’s Park Cemetery is home to several mammal species as well. Coyotes den there, and White-tailed Jackrabbits and Eastern Gray Squirrels are common.

White-tailed Jackrabbit, December 18, 2016.

White-tailed Jackrabbit, January 22, 2017.

Coyote, January 15, 2017.

So far, eighty-two bird species have been reported here on eBird. That is a pretty good total for a park that isn’t on the river. Sightings in the past week include Rough-legged Hawk, Golden-crowned Kinglet, Brown Creeper, White-winged Crossbill, and Pine Siskin. Get out and add to the total!

Winter Birds of the Weaselhead

Jan29

Posted by Bob Lefebvre

Many local birders have been heading down to the Weaselhead Nature Area recently to see several owl species, notable a Barred Owl, which is a species not often seen in the city.

Barred Owl, Weaselhead (South Glenmore Park), January 24, 2017. Photo by David Mitchell

The Barred Owl is usually seen on the north-facing slope of South Glenmore Park just above the Weaselhead. In the Weaselhead proper there have been sightings of a Northern Pygmy Owl, Great Horned Owls, and a Northern Saw-whet Owl this month.

The Weaselhead is a great place for winter birds as it attracts the visiting winter finches as well as many of our resident birds, and it has a variety of mammals as well. Below are some birds and mammals of the Weaselhead photographed by Tony LePrieur.

Pine Grosbeak, male, Weaselhead, January 8, 2017.

Pine Grosbeak, female/immature, Weaselhead, January 8, 2017.

Pine Grosbeak, male, Weaselhead, January 21, 2017.

Pine Grosbeaks are here in small numbers this winter and the Weaselhead is probably the best place to find them. They readily come to the feeding stations along the main path.

Bohemian Waxwing, Weaselhead, January 21, 2017.

Bohemian Waxwings roost overnight in the Weaselhead in huge numbers but might be found there at any time of the day in winter.

Common Redpoll, Weaselhead, January 8, 2017.

Common Redpoll, Weaselhead, January 21, 2017.

Another of our visiting winter finches, redpolls (common and Hoary) are here in small numbers this winter. They are easy to find in the Weaselhead as they also go to the feeders.

Black-capped Chickadee, Weaselhead, January 8, 2017.

Black-capped Chickadees are one of the most common songbirds in the Weaselhead year-round. You can also find Boreal Chickadees and occasionally Mountain Chickadees there.

Downy Woodpecker, Weaselhead, January 21, 2017.

Hairy Woodpecker, male, Weaselhead, January 21, 2017.

Other resident woodpeckers are the Pileated Woodpecker and Northern Flicker (Flickers are migratory but we have some here year-round). In winter you can sometimes find Black-backed and American Three-toed Woodpeckers as well.

Blue Jay, Weaselhead, December 6, 2015.

Dark-eyed Junco (Oregon subspecies), Weaselhead, December 6, 2015.

These sparrows are more commonly seen in the winter, and it is far more common to see the Slate-colored subspecies of Dark-eyed Junco.

Pine Siskin, Weaselhead, February 28, 2016.

Siskins are erratic in their movements and there are very few in the city right now. When there are big flocks around you will find them in the Weaselhead.

White-throated Sparrow, Weaselhead, December 6, 2015.

White-throated Sparrows are common breeders in the Weaselhead and you can hear them singing loudly there in the spring. Usually a few overwinter in Calgary, but I haven’t heard of any in the Weaselhead this winter.

American Tree Sparrow, Weaselhead, February 28, 2016.

Tree Sparrows pass through on migration but we often have some overwinter here. They will come to seeds under the feeders in the Weaselhead. Again, I haven’t heard of any this winter.

And now for a few mammals.

Coyote, Weaselhead, January 21, 2017.

Coyote, Weaselhead, December 6, 2015.

Meadow Vole, Weaselhead, February 28, 2016.

Meadow Vole, Weaselhead, January 28, 2017.

I seem to see more Meadow Voles in the Weaselhead than anywhere else. In the winter look for them scurrying under feeders to quickly grab a seed. They are the preferred prey for Northern Pygmy-Owls.

Bobcat, Weaselhead, December 13, 2015.

Bobcats are seen more often in the Weaselhead than anywhere else in the city. To see more photos of this one and the rest of its family, see this post.

The Weaselhead is also one of the best places in the city to see Snowshoe Hares and, in the summer, Least Chipmunks. Red Squirrels are also common, and it is one of the few places in the city where you can reliably find Northern Flying Squirrels.

Fall Migration on the Glenmore Reservoir

Nov3

Posted by Dan Arndt

Before the 2013 flood, the Glenmore Reservoir was always a great place to see hundreds of migrating autumn waterfowl and waders. In 2013 and 2014 though, the birds did not return in large numbers. One of the primary contributing factors to this was that with the sheer volume of water pulsing through the reservoir in late June of 2013, the bottom of the reservoir would have been either completely scoured of vegetation, or covered with silty and sandy sediment, killing the vegetation and invertebrate life that would otherwise thrive there. By the fall of 2015 though, the birds began to return in fairly decent numbers, and this fall was once again extremely productive. In the wake of any natural disaster, eventually things return to some level of stability and normalcy, and it was great to be back birding in South Glenmore Park and along the edges of the reservoir.

As per usual, we headed over to the ridge overlooking the reservoir to see what we could find out there. While we did see a few hundred American Coots at the far west edge of the reservoir, and a few Eared, Horned, and Western Grebes in close, there wasn’t anything close enough to really get good looks at without a scope. Thankfully we heard the tell-tale chipping of some American Tree Sparrows and Dark-eyed Juncos feeding below the spruce trees nearby.

We had a pretty good-sized turnout that morning, and so we split up, with my group taking the top pathway up away from the reservoir first. Given the slight chill in the air, we were all thankful to be off the water’s edge until it warmed up later in the day!

Roosting near its usual nesting spot, and after having a decent discussion about the ways to best distinguish between a Common Raven and American Crow, we found this fellow sitting atop a favored perch. It gave a few calls of different types as we watched it, and then finally flew off to join another Common Raven as it flew into the nearby neighborhood.

[exif id=”16227″]

As we explored the park, we heard the wheezy, raspy call of a Boreal Chickadee, which seemed quite out of place this far from the Weaselhead and the dense spruce cover of the slopes of the reservoir. Upon our investigation though, we found it stashing plenty of seeds in a small cavity near one of the homes with bird feeders set out.

[exif id=”16220″]

We also stumbled across a pair of young Mule Deer bucks, foraging in the low willows that were numerous throughout the upper slope of the park. Both looked to be only a year or two old, with only brow antler tines. They didn’t seem particularly disturbed by us walking nearby, which allowed us to notice one particular… anomaly.

He didn’t appear to be in any discomfort or distress, but this fairly well “endowed” deer did seem quite unusual. I welcome any suggestions or explanations on what might have caused this particular anomaly to this young deer. My suspicions are that it’s some type of tumor or cyst that’s caused the swelling.

American Tree Sparrow

[exif id=”16222″]

Just as we were meeting up with our compatriots, we managed another good few minutes of looking at a couple of American Tree Sparrows feeding right alongside the pathway. These guys tend to be a lot more shy, so it was a bit surprising seeing them hold still with walkers, joggers and going by fairly regularly.

fish jaw and clavicle

[exif id=”16223″]

Another mystery that we have yet to solve was this jaw and clavicle that we found on the edge of the reservoir. Again, I have my suspicions of its provenance, but would appreciate any comments and suggestions about what species was predated here on the edge of the Glenmore Reservoir. For scale, the clavicle was about 6-7 cm across, and the jaws were about 5-6 cm from back to front.

One of the birds that I had the hardest time identifying for the first few years of fall birding were the fall plumage Eared and Horned Grebes. I can’t tell you the number of times I would misidentify one or the other, and it wasn’t until the last year or so that I finally became comfortable telling them apart.

I’m going to leave these photos unlabelled for now, and I invite comments on what the putative IDs are on each of the birds below.

Fall Plumage Grebe 1

[exif id=”16225″]

Fall Plumage Grebe 2

[exif id=”16226″]

Fall Plumage Grebe 1 and 2 together

[exif id=”16217″]

When I look at a fall plumage grebe now, I look for four main features. First, I look at the head shape. Eared Grebes have a head that has a high crest at the front of the head, and slopes downward towards the back. Horned Grebes have a head that is more peaked at the back, and slopes up to that peak from the base of the bill. The second feature to look for is the shape of the bill. Eared Grebes have a pointed, dagger-shaped bill, that is ever so slightly curved upwards. Horned Grebes, on the other hand, have a thicker, more bullet-shaped bill, tipped with a very tiny white point.

Next I look at the plumage on the neck, back, and sides. An Eared Grebe has a much darker neck and face, with less distinct transition between white and black, and a more graduated blending between the back and the sides. The Horned Grebe, once again, is very sharply divided white and black on the face, neck, and usually on the back and sides. Lastly, the Eared Grebe has a light orange iris, and the Horned Grebe has a blood-red iris.

Sunday Showcase: Autumn in Calgary’s Parks

Catching up with some great autumn photos of Calgary Birds and Mammals, taken by Tony LePrieur from September 25 to October 16, 2016. The locations were the Inglewood Bird Sanctuary, Carburn Park, Fish Creek Provincial Park, and the Weaselhead Nature Area.

Boreal Chickadee, Bebo Grove, FCPP, September 25, 2016. The bird has no tail. Birds don’t molt all their tail feathers at once, so this indicates it probably survived an attack of some kind.

unnamed-1

Great Horned Owl, Bebo Grove, FCPP, September 25, 2016. These resident owls are fairly common it the city. Pairs will be spending the days resting on their winter roosts now, and by February (or sometimes even January) they will be on their nests, incubating eggs.

Great Blue Heron, Inglewood Bird Sanctuary, October 16, 2016. The herons have usually all migrated by mid-October, but a few may stay later.

Harris’s Sparrow, seen at the south end of the big bridge over the Elbow River in the Weaselhead on October 16, 2016. The bird was seen for at least a week, from October 16 to October 25. These Sparrows mostly migrate well east of Calgary and are a bit of a rarity here. They sometimes overwinter, so it is worth looking for.

American Tree Sparrow. These arctic breeders are passing through here now and some overwinter here.

Dark-eyed Junco. These sparrows are pretty common here in the winter and can be seen in residential areas right now, often feeding on the ground under bird feeders.

American Robin bathing.

American Robin. They passed through here on migration in huge numbers a few weeks ago, but there are always quite a few that overwinter here, mostly in the river valleys.

Northern Flicker (male). A migratory woodpecker, but again there are always lots in Calgary in the winter – either some local breeders that overwinter, or birds that bred farther north and migrated this far. They will readily come to suet and nut feeders.

Downy Woodpecker (male). A year-round resident that also will come to feeders.

Coyote.

Black-backed Woodpecker. A bit of a rarity in the city, they are occasionally seen in the west end of Fish Creek Park, from Bebo Grove to Shannon Terrace. This one was photographed there on October 23, 2016.

Pileated Woodpecker (male). Another resident woodpecker.

Rough-legged Hawk. This is the common buteo in our region in the winter. They have arrived in good numbers from their northern breeding grounds. Most commonly seen outside the city, especially west of the city.

Black-capped Chickadee. Year-round resident.

Muskrat. They are active all winter in open water.

Mule Deer buck.

Another no owl day at Griffith Woods Park

Feb17

Posted by Dan Arndt

Our walk this week returned to Griffith Woods, in search once again of the Great Gray Owl that had been a regular visitor there for well over a month now, as well as the Great Horned Owls and even a Northern Pygmy Owl that had been seen and heard there recently. The week got off to a good start, with Monday’s group having no trouble finding the Great Gray Owl, and the Tuesday group only missed it by a less than an hour before it flew off deeper into the dense spruce forest that are the hallmark of Griffith Woods.

Griffith Woods
February 16, 2014

The story throughout the day was that of distant birds and minimal photo opportunities, but I was very pleased that I was able to snap the shots that I did. When I downloaded my camera card at home, I found that I had only taken 31 shots in the course of the outing, so to have a 25% “keep” rate I think is pretty good!

The first real opportunity came when we spotted a small flock of Bohemian Waxwings high up in a spruce tree, and I was able to capture a pair of them breaking off from the group showing their rufous undertail coverts and the bright lemon yellow on the tip of the tail feathers.

We hunted along the trail under the power lines for any sign of the Great Gray Owl that was our quarry, but the only evidence we were able to find of it was this hunting impression in the deep snow, showing the impression of the head and wings as the owl hunted one of many unfortunate voles that had become its dinner.

Never let it be said that I know everything there is to know about all of the parks we visit. This week’s surprise was the discovery of another small pond on the north-west end of Griffith Woods Park. All it really would have taken was for me to look at one of the many maps that I’ve published even here on this website to actually notice its presence, but thankfully Gus Yaki came to the rescue again and showed us where all the Canada Geese we had seen all morning were flying to. Also on this pond was a lone Common Goldeneye, and much to our surprise and delight was a solitary, and very uncharacteristically quiet, Blue Jay along the hedgerow behind one of the nearby houses.

Another nice surprise was a pair of Dark-eyed Juncos feeding underneath a spruce on the way back into the park after we had finished exploring the pond.

And then the wind picked up, and everything got quiet. While we retreated deeper into the wooded trails, the birds came fewer and further between, and only stayed in sight for mere moments at a time. Even our last species of the day, this Rough-legged Hawk, disappeared a few seconds after I spotted it soaring high above the nearby homes, but enough to positively identify it with its distinct dark wrist patches.

And so wraps up another week of the Friends of Fish Creek Winter Birding course. Next week we head back to Bebo Grove in search of last week’s quarry, the American Three-toed Woodpecker, along with another Great Gray Owl, a Barred Owl or three, and hopefully a Northern Saw-whet Owl!

Have a great week, and good birding!

Birding at South Glenmore Park never fails to impress

Oct21

Posted by Dan Arndt

Before I start this post, I want to mention that this week’s entry is going to include some photos from a visit I took to the park a week ago as well, partly because there was a significant paucity of expected birds here this week, but also to highlight a local rarity that passed through late last week as well. The usual map will also indicate the location of the older photos.

This week’s location was South Glenmore Park, with the goal in mind to see some migrating waterfowl and other associated water birds, and to highlight that with some of the boreal and parkland birds along the north-facing slope of the Glenmore Reservoir. While we did have some incredibly memorable experiences with the latter, the uncannily quiet morning in general led to my decision to include some photos from last week as well.

South Glenmore Park and Glenmore Reservoir

Our morning started off on a high note, with one species I don’t know if I’ve ever actually posted a photo of to this blog. While House Sparrows are invasive, and by far my most numerous feeder bird at home, they’re more often heard than seen out on our walks, and even then, not one we get more than four or five times a season, since our walks are in more natural areas. I do think they’re quite an attractive bird overall, and one of the few sparrows where one can easily tell the males and females apart.

As we scanned the Glenmore Reservoir a few minutes later, it was clear just how quiet the day was going to be. The only bird on the water was a single Common Loon off in the distance. I mentioned in a previous post that the floods this summer flushed all the vegetation, and as such, all of the aquatic life out of the reservoir, meaning that any birds that touch down on the reservoir overnight typically are gone either before or shortly after dawn, as there’s next to nothing around for them to eat. One exception was a Sabine’s Gull that stuck around for three days last week. A hatch-year bird, by all indications, and as such, was incredibly unwary of people. When I took this photo, a group of workers at the Sailing Club to the left of the frame was moving around a few boats, and at the shop a hundred meters or so away, repairs were well underway with the constant din of saws, hammers, and lathes hard at work.

Early in our walk, the Common Loon was quite far off, but after we scanned the reservoir and began our walk down the slope to the lower pathway, it took off and flew into one of the bays a bit further west, sitting only a few dozen meters off shore.

Along the lower pathway, we heard the brief calls of an American Tree Sparrow, and a few Dark-eyed Juncos, but didn’t get very good looks at them. It also seemed that their numbers were far fewer than they had been the week prior, for one reason or another.

The distant Common Loon flight was quite reminiscent of the Sabine’s Gull of the week prior, flying along an almost identical path. In this photo of the Sabine’s Gull, you can see two very distinct field marks for identifying the species: both the jet black primary flight feathers, and the bold, pure white triangle formed by the secondaries and tertials are great identifying marks for the Sabine’s Gull.

Our first looks at the Common Loon up close were fairly satisfying, but if you look closely in the photo of it in flight above, it appears to have suffered some damage to its flight feathers, which was pronounced when we were able to view it closer as it spread its wings twice to dry them off. Whether the damage is from an injury, or a late molt, one way or another this little bird is in for a rough few weeks.

And then came the quiet. For the next twenty or so minutes we walked along, feeding some Black-capped Chickadees, hearing a Golden-crowned Kinglet or two, but seeing almost nothing close on the reservoir. The most excitement we had was watching a Bald Eagle harass an unseen water bird (likely an American Coot) for a good ten minutes before tiring of the chase and perching nearby, just before we headed up and away from the reservoir.

Walking along the upper pathway was just as eerily quiet. We passed through at least three small flocks of Black-capped Chickadees on the upper trail before hearing the distinct call of a Pileated Woodpecker, a nice surprise on any walk. It appeared that a Cooper’s Hawk was harassing a small family of Pileated Woodpeckers. No less than three of them were flying back and forth along the upper ridge, until a flock of about ten Black-billed Magpies came in and flushed the hawk away. Unfortunately, the Pileated Woodpeckers stayed well away from the trail we were on, allowing very few photo opportunities.

And to add insult to injury, that was our last good sighting of anything for the day. We did have a really nice view of the Calgary skyline from the pathway as we approached the parking lot, and a surprise visit by a Common Raven that flew in close to us as we prepared to leave.

It’s not often you get close looks at Common Loons on the reservoir, so after the group left, I made an attempt to get close to the loon we’d seen earlier, and I was not disappointed. It seemed to not be particularly wary of my approach, and I spent a good 10 minutes with the bird before it swam out away from shore.

Thanks again for reading! Have a good week, and good birding!

Backyard Birds: Dark-eyed Junco

Dec8

Dark-eyed Juncos are one of the last native sparrows to migrate through Calgary each fall, and many of them often overwinter here. I have at least eight that have been coming to my yard regularly for the last three weeks. They will come to feeders, but like other sparrows, they prefer to feed on the ground or on a flat, open surface like a tray. They can often be seen scratching in the snow to expose seeds.

Juncos can be identified by their dark hoods, white bellies, and white outer tail feathers that flash when they fly. There are two common subspecies in Calgary; “Slate-colored” which are all grey and can look almost black, and “Oregon” which have rusty back and sides. In the spring, males have a very distinct black hood.

I have a non-native apple tree in my yard that stays green and fully leafed out until the end of November, so I often only become aware of juncos in the yard when I hear their soft “chip” call coming from the tree. The video below includes a soundtrack with this call, courtesy of the xeno-canto website.
