The popular Friends of Fish Creek birding course begins its 12-week spring session on April 3, 2017.

Go out on field trips with experienced leaders once or twice a week for twelve weeks, and learn about the birds of Calgary. You can expect to see over 150 species of birds.

Field trips are held in several parts of Fish Creek Park, in Carburn Park, Beaverdam Flats, the Inglewood Bird Sanctuary, the Weaselhead Nature Area, Bowmont Park, Elliston Lake, Griffith Woods Park, and possibly other locations.

It is still only $5 for children (accompanied by a registered adult) for the whole twelve-week course! See this page for details on how to register.

Here are just a few more of the many birds seen on the winter course this year.

Birding Locations: Queen’s Park Cemetery

Posted by Bob Lefebvre

Northern Goshawk, Queen’s Park Cemetery, January 28, 2017. All photos by Tony LePrieur, all taken at Queen’s Park Cemetery..

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.

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

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.

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.

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!

Sunday Showcase: Autumn in Calgary’s Parks

Posted by Bob Lefebvre

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.

unnamed

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.

image1

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

image2

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.

image3

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

image5

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.

image6

American Robin bathing.

image61

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.

image7

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.

image8

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

image10

Coyote.

image1

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.

image2

Pileated Woodpecker (male). Another resident woodpecker.

image3

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.

Terry’s Travels: The Irricana Sloughs

By Terry Korolyk 

On Saturday, September 17, I decided to go birding to the area between Strathmore and Irricana as my wife was otherwise occupied. This included an area known as the Irricana Sloughs, a once well-known birding destination for many birders in the 1980s, 1990s, and, early in the new millennium. Today, it is still visited by some birders, but, these days more areas have been explored and opened up for birders, so, the choices are greater.

Nonetheless, I set out on this beautiful Fall day. I had chosen the large slough at the Cattleland Feedlots at the north end of Highway 817 north of Strathmore as my starting point. On the way out there, I passed a few migrating Swainson’s Hawks some of them following farmers on their machines who were busy cutting their crops, then, driving north of Conrich, as I approached Highway 564, a congregation of Black-billed Magpies and Ravens were gathered along the roadside. I slowed down hoping to see what the reason might be for this gathering, but, could see nothing.

When I arrived at Cattleland, I was hoping to see Greater White-fronted Geese as over 300 of the birds had recently been reported there. This site had become known as the one that almost always had the first birds of that species to arrive in our area in Fall migration usually in late August. The same had held true this year. This location and Namaka and Eagle Lakes southeast of Strathmore were the best White-fronted Geese sites near Calgary.

img_8793-cattleland-islands

Islands at Cattleland Reservoir. Photo Sept. 17, 2016

But, none were there on this day. The water level was high, but, it had been that kind of Summer. The slough has 3 islands which, with the now high water, were not that far above the surface of the water. Birds tend to congregate on them, and, in breeding season, Terns, both Common and Forster’s, and, once, even a pair of Arctic Terns raised their young on them along with other species such as Canada Goose, American Avocet, and, Black-necked Stilt. This nesting of Arctic Terns in the interior of the continent was not a first; it had happened previously in Montana.

In any event, so far this Fall, the islands were being used primarily by Gulls, including all of Ring-billed, California, and Franklin’s, and, Double-crested Cormorant. Today, there wasn’t that much there to interest a birder. A flock of 13 Baird’s Sandpipers was a highlight and flocks of Icterids there such as Brewer’s, Red-winged, Yellow-headed Blackbirds and, Brown-headed Cowbirds had dwindled in numbers. Large numbers are attracted by the Feedlot following breeding season. By the way, those birding the site must be aware that sometimes a repugnant odour may waft over from the feedlot so, be warned.

I moved on from Cattleland driving eastward on Highway 564. A few kilometres on, I turned northward driving past the few residences composing Nightingale. As I turned, a male Common Grackle flew past the car. I kept on northward a few kilometres turning westward on to Township Road 262. Drive a short stretch and a very large wetland appears on the north side. I was in luck today; over 600 Greater White-fronted Geese were at the wetland. Amongst other large numbers of waterfowl were 10 Taverner’s Cackling Geese, and an adult Bald Eagle, and, a juvenile Barrow’s Goldeneye.

img_8806-white-fronted-geese

Greater White-fronted Geese at Range Road 245-Township Road 262 wetland, Sept. 12, 2016.

Whenever I visit this area, I try to visit this location for another reason, that being it is an excellent site for birding for passerines with nearby woodland; a willow swale, and shrub-lined and treed north-south orientation irrigation ditch running under the road to a wooded area. Large numbers of birds can move along the ditch to the woodland and birds found here have included large numbers of Yellow-rumped Warblers with other Warblers being all the common ones plus Chestnut-sided, Magnolia, Cape May, Black-throated Green, Townsend’s, Palm, Blackpoll, American Redstart, Northern Waterthrush, and, Ovenbird. I have found both Hermit and Swainson’s Thrush here along with Rusty Blackbird. Once in November, I found a Swamp Sparrow along the irrigation ditch, and, I have found Long-eared Owl in the woodland.

Driving westward from here, you enter the realm of the Irricana Sloughs starting with Long Lake just west of Range Road 253. Continuing westward will take you to Bruce Lake east of Keoma. One can head into “the Sloughs” from Twp. Rd. 262 going northward on Range Road 253 or by going north on Range Road 261. The heart of “the Sloughs” is generally acknowledged to be the waterbodies from the Range Road 261 junction eastward, and, also north from Township Road 270 north on Range Road 254.

img_8817-heron-and-cormorants

Great Blue Heron and Double-crested Cormorants at Railway Slough.

The Irricana Sloughs offers a variety of birds. In recent years, some of the water bodies have become very popular with Grebes. Pied-billed and Red-necked Grebes both nest in substantial numbers on the large slough on Township Road 270 immediately west of Range Road 261 and on the slough on the east side of Range Road 261 just south of Township Road 270. Immediately east of the slough on Twp. Rd. 270 east of Range Road 261 is a slough called Railway Slough which, next to Namaka and Frank Lakes, is the most convenient place in the Calgary area to find Western Grebe during breeding season. If one continues eastward on Township Road 270, one may find Horned Grebe at some of the smaller marshier sloughs.

img_7611-bittern

Bittern at marsh on Twp. Rd. 270 east of Range Road 261, June 4, 2016.                 

Another specialty of the area is the American Bittern most often found in marshy areas at the slough west of Railway Slough and at the marshy slough on the west side of Range Road 261 directly north of Township Road 270. Upland Sandpiper has often been found in grassland along the roads in the area, and, in the past, “the Sloughs” were a fairly reliable location for finding Baird’s Sparrow, an uncommon species in our area. However, there have not been many reports in recent years, but, the area is not birded as thoroughly as it once was. Both Nelson’s and Leconte’s Sparrows have, in the past, been fairly noticeable by call in some of the wetter, grassier areas. Sprague’s Pipit and Long-billed Curlew is often found in the grassland areas, and, Marsh Wren can be found in Cattail marshes.

The Irricana Sloughs used to be one of the most reliable and nearest sites in our area for watching Loggerhead Shrikes. The species has expanded its range somewhat closer to Calgary, but, Loggerheads are still found in the area. Also, if visiting the Irricana Sloughs watch for the Krider’s subspecies of Red-tailed Hawk which used to be fairly regularly seen. Western Kingbird is also a specialty of the area, but, Eastern Kingbird is also resident. Double-crested Cormorant and American White Pelican can be found on Railway Slough and all the other larger sloughs.

The series of ponds and sloughs on Range Road 254 just south of Township Road 273 are probably the best shorebirding locations in the area being at the north end of the area and with lots of shoreline. All the regular species have been there with rarer species including Hudsonian Godwit, White-rumped Sandpiper, and, Red-necked Phalarope. One of the first occurrences of breeding in the area during the rise of the Black-necked Stilt in southern Alberta in the late 1980s and early 1990s was in this area.

img_1655_22-nesting-stilt

Nesting Black-necked Stilt.

The Irricana Sloughs have for quite a number of years now hosted small numbers of non-breeding Bonaparte’s Gulls during breeding season, mostly on Railway Slough or the slough directly west of Railway Slough. Large numbers of Swans, mostly Tundra, stop off here in migration and the Siberian counterpart to the Tundra Swan, the Bewick’s Swan has been seen here. An adult Whooper Swan paired with an adult Tundra Swan found on April 6, 2000 in “the Sloughs” was seen by many until April 11, but, its provenance was questioned by the Alberta Bird Records Committee. Was it a wild bird or an escapee? To me, the ABRC has shown itself to shy away from making tough decisions. Wild Whoopers have been reported in the Pacific Northwest, but, they are also held in captivity.

2786-whooper-swan

Other sloughs included in the area lie on Township Road 264 west of Range Road 261 and on Range Road 264 south of Township Road 264. The slough on Twp. Rd. 264 is a marshy slough which is one of few water bodies east of Calgary which regularly hosts Common Loon during breeding season. One of the leucistic Great Horned Owls was found in the woodland in the northwest corner of the lake as you drive westward past it. A Tennessee Warbler, a species native to the foothills and mountains in the western part of the province, was heard singing in this woodland one Summer. As you continue westward, you would turn southward on Range Road 264. The large water body on your right is called Spoonbill Slough for a Spoon-billed Sandpiper, a Siberian species of shorebird, that was twice reported there. Alberta’s only Baikal Teal was found here and Greater White-fronted Geese stop off here. This water body usually hosts a good variety of species. Nelson’s Sparrow have been regular in the wet grasses at the south end.

Two other sites included in the sloughs are a marsh and woodland a couple of kilometres north of Township Road 270 on Range Road 252 and Range Road 255 running south from the Range Road 254-Township Road 270 junction. The Range Roads both these locations are situated on supply North-South orientation and, thus, provide excellent movements of migrating passerines. All the basic small songbird migrating species have been found on Range Road 252 with others being Philadelphia Vireo and, also, Broad-winged Hawk. A leucistic Great Horned Owl was found there on  a Field Trip. The same can be said for Range Road 255 with Palm Warblers particularly having favoured this road. One Fall day I found several Palm Warblers in migration along the road, but, this also included 3 birds that were so brightly-coloured, I thought they may have been of the Eastern subspecies, the Yellow Palm Warbler.

img_4352-leucistic-owl

Leucistic Great Horned Owl on Twp. Rd. 264 west of Range Road 264.

Probably the final water body that should be included in the Irricana Sloughs region is Bruce Lake which is on Township Road 262 a short distance west of Range Road 261. The road makes a big bend around the north end of the lake, then continues westward to Keoma with Highway  9 beyond. Black-crowned Night Herons and California Gulls used to be common along the stream at the north end and rarities found include Snowy Egret, Black-legged Kittiwake, and, Pacific Loon. Both White-winged and Surf Scoters have been seen on the lake in the Fall season. The woodlands at the north end of the lake can be good for migrating songbirds with Long-eared Owl also being found there. In the winter, Northern Goshawk has been found there, and, Ring-necked Pheasant may be found in the cattails and other marsh grasses.

img_2396_5-adult-little-gull

Other rarities found in the Irricana Sloughs include Cattle and Great Egret, Little Gull, Sabine’s Gull, Red Phalarope, Sage Thrasher, and Yellow-billed Loon. Sandhill Crane, Townsend’s Solitaire, both Surf and White-winged Scoter, and, Turkey Vulture have all stopped off in “the Sloughs.” One rarity I was astonished to see was a THREE-TOED WOODPECKER flying from tree to tree one Fall day along Range Road 261 just south of Township Road 270. This, of course, is a species native to the CONIFEROUS forests of the foothills and mountains!

Gyrfalcon, Oct. 19, 2013.

Great Horned Owl is resident. Winter sees Snowy Owls and all of Gyrfalcon, Prairie Falcon, and, Rough-legged Hawk found in the area while weedy fields and ditches attract both Common and Hoary Redpolls, while, windswept fields and roads attract both Snow Buntings and Horned Larks. Some winters you may even find a Northern Goshawk out on the prairie there.

————————————————————————————-

Fall Migration, 2016——

Sabine’s Gull, always a much sought after bird in the Fall, was a bit late showing up this year. The birds are usually here by the first week of September, but, this year September 16 was the first date of report with an adult and an immature bird at Calgary’s Glenmore Reservoir. Since then, a single Sabine’s was seen at Tofield and 3 birds were at Frank Lake east of High River. The 2 Glenmore Reservoir birds were joined by a single bird on September 17.

Major highlights so far include an adult hybrid CALIFORNIA GULL-RING-BILLED GULL at the Shepard Landfill at the east end of McIvor Boulevard in southeast Calgary on September 22, and, a juvenile LITTLE GULL at the Chestermere Lake Dam on September 26. Five first-cycle Thayer’s Gulls were at the Peigan Trail Gull Ponds below the City of Calgary Landfill on September 22.

A male BLACK-THROATED BLUE WARBLER was photographed in a yard in Canmore on September 23. While still a vagrant in the province, the species is fairly regular with most reports coming in the Fall in frosty or near frosty weather.

Scoters are starting to hit the Calgary area as of this writing with 5 Surf Scoters at Glenmore Reservoir and another 5 were with a White-winged Scoter at Eagle Lake, all of these birds being seen on September 23. No northern Loons as yet.

There have been more Swamp Sparrow reports than usual in the Calgary area this Fall, and, also a couple of wandering Varied Thrushes. A Harlequin Duck was reported via  E-bird at Wyndham-Carseland PP on September 18.

Snow Geese are slow to arrive this year, but dark and unusual morph Red-tailed Hawks are seen almost daily now in the Calgary area. There are still some Swainson’s Hawks around, while there have been only a couple of Rusty Blackbird reports so far. From Ken Orich, young Barn Swallows fledged from a nest at Tillebrook PP at Brooks on the amazing date of September 19!

Until next time.                                                                      Terry Korolyk

Terry’s Travels: It’s Great Seeing Great Horned Owls!

By Terry Korolyk

IMG_6214

Since starting birding in the Calgary area in 1987, I have had the good fortune to be able to see many Great Horned Owls in my travels. As most people know, the Great Horned Owl is our provincial bird. It is widespread, but, local; common in some areas but not others. I get the impression the species is not as common as it used to be, but, we must remember, it is local. A check of this year’s Calgary area May Species Count data held annually the last weekend in May revealed that of a total of 31 Owls recorded, 18 were recorded in only 6 city territories. Leading the way was the Burnsmead east Fish Creek PP territory which had 6. Mallard Point Fish Creek PP, also along the Bow River, had 3. Baker Park in northwest Calgary had 4. These numbers mean that all the rural territories totaled only 13 birds with South of Strathmore leading with 4, and, the Carbon-Acme areas having 3 birds. That’s a total of 7 birds meaning all the other rural territories totaled only 6. Maybe it isn’t me and the species is not as common as it used to be, at least in rural areas. To be fair, numbers would have to compared against past years.

In the 1990s, and, even in the early stages of the new millennium, you could pretty well expect to drive out on the prairie east or southeast of Calgary and expect to see more than one Great Horned Owl perched on the top of a telephone pole, or, on the crossbars of a telephone pole in the fading light of the afternoon as they were preparing to launch themselves off to begin another night on the hunt. One such bird from those days was this bird I photographed along a road in the Blackie area.

IMG_6159

This particular bird, quite dark brown, appears to be somewhat of a battle-scarred veteran with stubby eartufts, one of them flopped over, and a long scar stretching  from one of the bird’s shoulders down one side of its breast. We can only speculate as to how the bird got that scar. These days, I have much more trouble just chancing upon a Horned Owl than I did in those days. I can recall one afternoon in that area when I observed 3 birds not all that far apart enacting that very scenario.

However, we must remember that the species is local. For instance, there was at least one pair that every winter roosted in the White Spruce trees against the back of the building on the north side of Sikome Lake in east Fish Creek Provincial Park in Calgary. Many people knew about them, and, the birds may have been amongst the world’s most photographed Great Horned Owls. At least  1 pair of the birds nests in the vicinity every year, sometimes in a tree cavity. Just down the road from Sikome Lake, one can walk the pathway between the Coniferous trees at the Fish Creek Park’s Visitor’s Centre, and also have a good chance of seeing at least one, if not more birds there. Long-eared Owls have also been found in these trees. Carburn Park on the other side of the Bow River from Fish Creek PP used to be a reliable site for finding Great Horned Owls, but, this year’s MSC numbers showed only 1 bird there. Refer to the opening paragraph for areas where the birds are most common, at least in May of this year.

In Great Horned Owls, as in all other Raptors, the female is larger than the male as is nicely illustrated by this pair photographed near Lake McGregor at Milo.

This partnership will soon lead to nesting –

– as indicated by one of a pair perched beside the nest, which in this case, was along 146 Avenue near a farm in southeast Calgary before it became the Copperfield and New Brighton subdivisions. Nesting eventually leads to the production of young –

– such as this particular bird which was fledging from a nest near the creek in the Votier’s Flats area of Fish Creek PP. Mummy was down on a rock in the creek at the time hunting in the daytime to feed her youngsters. Once the young have fledged, they are officially Great Horned Owls.

In the immediate Calgary area, Great Horned Owls seem, in my experience, to be predominantly grayish birds such as this particular bird:

However, no 2 things in a species are perfectly alike, so, the degree of grayness and the arrangement of the bars, streaks, and other markings and colours produces no 2 identical individuals. Note the attractive contrast on this Owl between the white tail and the rest of the bird:

While some birds in the Calgary area can be somewhat darker or lighter; birds, in the foothills seem to be, in my experience, to be somewhat darker gray such as this individual:

Remembering that no 2 snowflakes are exactly alike, look at this darker gray individual, but, look at the unusual blackish face.

The city of Calgary sort of lies on the fringe area and some of the birds you see in the area may not be gray and white, but, may have some small degrees of brown, or, reddish-brown tinged feathers. Generally, the further east and south one goes from Calgary, the more liable one is to see birds with brownish, or, reddish-brown tinged feathers and, also, the browner the feathers may be. Look at the scarred veteran of the opening paragraphs and look at these 3 individuals, all photographed at sites east of Calgary:

All these birds show varying degrees of brown and reddish-brown feathers.

But, it doesn’t end there. Aberrant plumages do occur. I photographed a leucistic Horned Owl once while guiding for a birder from Virginia in the United States, and, I have seen at least 2 individuals that were probably Subarcticus, or West Taiga subspecies birds being very, very pale gray and showing a lot of white. One bird was on the Calgary Christmas Bird Count along railroad tracks in open grassland on the eastern edge of the city, while the other was at a marsh in the hills south of Calgary during wintertime.

The moral is—- be on the lookout for a variety of Great Horned Owl plumages in our area.

On the local birding scene, Fall shorebird migration thus far has been rather unspectacular, but it is early, with the “best” bird being a Ruddy Turnstone on a muddy spit seen from the viewing area at the south end of Weed Lake at Langdon. Lesser Yellowlegs have shown up so far in strong numbers. Migrating passerines detected on the move already include Yellow-rumped Warbler, Western Tanager, Swainson’s Thrush, Tennessee and Wilson’s Warblers. The report of up to 3 Purple Martins at the south end of Weed Lake recently is unusual as there are rarely reports away from the species’ local stronghold colony at Chestermere Lake. Caspian Terns are being reported with the most recent report coming from the Carseland Weir. Other recent reports have been from the north access of Langdon Reservoir and the south end of Weed Lake. There have been 2 reports of Grasshopper Sparrows from our area in July with one bird being seen south of the Mallard Point parking lot in east Fish Creek PP, and, the other bird photographed carrying food south of Keoma which is on Township Road 262 a short drive east of Highway 9. These birds are north of their range in the province. Recent rarities include a Northern Mockingbird near the Twin Valley Dam east of Parkland on July 13, and, a Great Crested Flycatcher in the Bearspaw region of northwest Calgary on July 12.

The city of Calgary Rare Bird Alert (RBA) number is 403-221-4519. If you have found a rare or unusual bird, noticed some unusual interesting bird behavior, noticed an unusually large number of individuals of a particular species of bird, or have seen a bird in the province out of season, by all means, report it.
