Backyard Birds: White-crowned Sparrows

May10

It’s a sure sign of spring in my yard when I see the White-crowned Sparrows are back.

A fairly large sparrow at 5 1/2-7″ (14-17 cm), White-crowns don’t fit the miscellaneous sparrow category of LBJ’s – little brown jobs – that are hard to distinguish from one another. These dapper little sparrows are always in bright white and black, and easy to identify.

The white crown has two black stripes, they have a black eye line (a line going to the back of the head from the eye), and a yellow-orange bill. They have white streaking on a brown back and wings, and their underparts are pale grey. Males and females look alike.

Small flocks of White-crowned sparrows pass through Calgary in late April to May, and then again in Sept-Oct. Their spring visits to our city are just a stopover for their trip to their breeding habitat in the northern boreal forest. They prefer open environments with shrubby meadows, alpine and willow shrubs, and build cup nests in shrubs or small conifers.

These sparrows are tireless singers, and are known to even sing under the light of a full moon.

Sparrows forage on the ground, usually in fairly open areas, and fly up into a small tree or hedge when flushed. We have a dedicated bird area at the back of our yard, and spillage from the hanging bird feeders provides an excellent sparrow feeding ground. Like other sparrows, the hyperactive White-crowns make quick jumping back and forth movements, scratching the ground to expose insects and seeds.

If you have White-crowned Sparrows in your yard right now, enjoy them while you can. They won’t be here for long, and then we’ll have to wait for their re-appearance in the fall.

By the way, the bird singing in the video background is a Ruby-crowned Kinglet, which I’m still attempting to capture with my camera.

Free Summer Bird Walks

May10

Last week, the first of Nature Calgary’s Tuesday evening bird walks was held.  For those of you who can’t make it out on weekend mornings, these evening walks may be a good opportunity.  Throughout the spring and summer, a free birding field trip to one of Calgary’s many parks will be offered every Tuesday beginning at 6:30 p.m.

Inglewood Bird Sanctuary

For information on upcoming walks, check the “Free Nature Walks” page on our banner above.  The page is updated regularly.  This evening, May 10, the field trip will be at Edworthy Park in the northwest.  Spring migration is getting into full swing, so get out and see the latest arrivals.

Carburn Park

All Nature Calgary field trips are free and open to all members of the public.  You don’t have to be a member of Nature Calgary to attend.  If you need any more information about a particular walk, you can phone the walk leader at the number listed.  But in general, you just have to show up!  Dress for the weather, have your binoculars and/or camera ready, and have fun while learning about the birds of Calgary and our natural areas.

Migratory Bird Day: The Big Sit

May8

Saturday May 14 is World Migratory Bird Day.  To celebrate this, and to see the birds of Calgary at the peak of our spring migration, Birds Calgary will be doing a Big Sit at the Inglewood Bird Sanctuary.

Sit birding is an activity that requires the birder to count all the birds that are seen and heard while remaining within a circle seventeen feet in diameter.  Essentially, you stay put and let the birds come to you.  On May 14, the Birds Calgary writers will see how many species they can find from a spot in the Inglewood Bird Sanctuary near the Bow River.

Inglewood Bird Sanctuary, 2425 9 Avenue SE, Calgary

We will begin the count at 8 a.m. and go until 11 a.m (noon if the birds keep coming).  Anyone who wants to join us for the count and help out is welcome.  You can also just drop by at any time during the count to see how we are doing.  If you plan to stay, bring a lawn chair, binoculars, water, and either sunscreen or rain gear (or both) as the weather requires.

I hope you can join us next Saturday for a great morning of birding!

Help Us With the May Species Count!

May7

The May Species Count is an event held on the last weekend of May each year, in which birders try to find every species of bird in the Calgary area.  Over the two-day period, teams or individuals scour their assigned areas to identify every bird species they see and hear, and also note the total numbers of each species.  This year the count will be on May 28 and 29.

How many Mallards?

The area covered is huge – a circle 160 kilometres in diameter centred on the Centre Street bridge in Calgary.  Organizers have broken the count circle into many smaller territories, and assigned volunteers to each area.  We need a lot of birders to cover all this territory!

          The Count Circle.  The numbers indicate the territories to which birders or teams of birders are assigned.  Click on the map to enlarge it.

There are still some territories that are not covered, so if you want to contribute to a very worthwhile citizen science project, contact the co-ordinator:

Terry Poulton  –  May Species Count, May 28-29, 2011

phone    403-274-7393        email    tpoulton@yahoo.com

Everyone is invited to participate, whether beginner or seasoned pro.  You can do a whole day, a half day, or both days.  Terry will try to assign you to an interesting route, and try to match new-comers with experienced birders, and drivers with riders.  There are a wide variety of environments, from urban to prairie to foothills habitats. Most years, more than 200 bird species are seen in total within the circle.

This is a great opportunity to get involved in Calgary and area birding, and to see as many as one hundred species of birds in a single day.  If you can identify most birds you see, you can survey an area yourself.  If you are a new birder, you will be assigned to a team with other experienced birders where you can help to spot and count birds, and learn about the process.

If you are at all interested in this, please contact Terry to get more information.  It’s one of the funnest birding experiences of the year, at the birdiest time of the year!

Photo Feathers: Pine Siskin

May6

The Pine Siskin is a familiar, tame little finch. They are often very approachable, enough to see their beautiful feathers. They are quite noisy, even while they feast on niger, black oil sunflower seeds and the seeds of pinecones, among other foods. Pine Siskins are common in Calgary and can be seen year round.

The Pine Siskin is a very curious bird; the bird in this photo is curious as to who is bothering him.

The Osprey Cam – They’re Back!

May3

For over 16 years, a pair of nesting Osprey has built their summer home on a platform constructed by the Calgary Zoo atop a pole erected by ENMAX Power Corporation. The platform is located at the extreme east end of St. George’s Island.

Birdwatchers have access to a bird’s eye view of an Osprey nest via a high-resolution webcam, thanks to an arrangement between the Calgary Zoo and ENMAX Corporation.

The live streaming camera captures in full cycle the birds’ dramatic seasonal milestones, from nest building and mating rituals, to egg laying, incubation, hatching, feeding and fledging, a period of intense activity that is all centred at the nest between April and September.

Watch the Osprey nest camera live, 24 hours a day (If you click the icon in the bottom right hand corner of the video, it will go to full screen size. To leave full screen view, hit the Esc key on your keyboard)

There is also an Osprey Blog following the action in this nest

Bountiful Birding at Frank Lake

May2

Last week I took the short drive out to Frank Lake, east of High River (see the directions under the “Birding Resources” tab above).  I was hoping to see some of the many Short-eared Owls that are often seen there at dusk, and I had about two hours before that to scope out the lake for waterfowl and other birds.  This is a very productive wetland, and I managed to see 24 species of birds, 13 of which were new ones for the year for me.

The water level is very high this year.  As you can see, the path to the observation blind was flooded.  There was also still quite a bit of ice on the lake, but much of Basin 1 was open.

By far the most common bird there was the Franklin’s Gull.  Frank Lake is home to perhaps the largest breeding colony of these gulls in the world, with up to 55,000 pairs.  They build floating nests in the cattails, and if the water levels remain this high they may not be able to breed here successfully.

There were other gulls as well.  This one, which I believe is a California Gull, was having eggs for dinner.

The gull took the egg onto the roof of the blind, and although it almost rolled off at one point, he finally did manage to eat it.

I had good views of Eared Grebes and Ring-necked Ducks…

But the highlight was when a flock of four White-faced Ibises flew in.  I had never seen this large, beautiful bird before.  It has dark, glossy, chestnut and bronze colouration, a long decurved bill, and of course a white face.

(Click on photos to enlarge them.)

The four flew on, but a little later another flock of twelve Ibises arrived…

They landed on the island…

And virtually disappeared in the grass…

(Cinnamon Teal in the foreground.)

At dusk, I started to drive back out on the dirt access road, but I didn’t get far, since I brake for Short-eared Owls…

This owl was right next to the road, so it flew before I could get very close.  However,  I saw another one hunting a little farther down the road…

All in all, a great evening of birding topped off by a fine southern Alberta sunset.

Must-see birds: May

May1

May is a great month for birds here; plenty of migrants, warming weather and leafless trees combine to make this month arguably one of the best months to see birds in the Calgary region. These factors therefore make it extremely hard to make a decision on just 5 birds to make the cut; but it had to be done, so here they are.

1. Horned Grebe    

The Horned Grebe is a small, attractive grebe, a family of aquatic birds seldom seen on land or in flight. The Horned Grebe has a chestnut neck and flanks while its black head is topped with contrasting golden horns. A beautiful bird, the Horned Grebe qualifies easily for the month of May. The Horned Grebe does not breed in Calgary but as it passes through, up to mid-May, you can try to see one at Elliston Park or the Glenmore Reservoir.

2. Black-necked Stilt

A large shorebird that is an erratic and local breeder here in southern Alberta, the Black-necked Stilt has very contrasting colors; black upper parts, white underparts and  very long, geranium-red legs. Its long, slender bill is always probing for food as its sharp eyes scan for both food and danger. This Stilt can be seen in wet pastures and on the grassy shorelines of shallow water, especially where there are plenty of mudflats. The stilt was virtually unknown in Alberta until 1994, but now, you can try to find it at places like Shepard Slough, Chestermere Lake and Weed Lake, Chestermere and Weed Lake being outside of the city.

 3. Western Tanager

The male Western Tanager is a very striking bird, easily making it on our list, with a bright red head, black wings, back and tail and his canary yellow neck, rump and underparts. The Western Tanager eats insects and fruits and feeds among bushes and trees, also hawking insects from the air occasionally. The tanager’s main habitat are boreal and montane forests; often being found in coniferous and mixed wood areas. The Tanager does come through Calgary on migration; I had one in my mountain ash in May of 2009. The best places to see this amazing bird are the north end of Weaselhead and the west end of Fish Creek Provincial Park.

                                                                                                                                                                                                                                                     

 4. American Avocet

A handsome and showy shorebird that can often be seen foraging in shallow water or on the barren mud flats along the edges of lakes. A light cinnamon color adorns the Avocet’s head and neck in the breeding season with the rest of its plumage being black and white. These birds start converging in large flocks in central Alberta usually in early May and can be seen best at locations like Shepard Slough and Frank Lake.

5. Yellow Warbler

The male Yellow Warbler is a brilliant yellow with olive-green wings and reddish breast streaks. This is a common bird and has a wide distribution throughout the province, thanks to its ability to nest in a large variety of areas. The female is similarly colored, but is more green above and drabber below. The male, despite his bright colors, is surprisingly well camouflaged and is best seen when the trees still lack their leaves. The Yellow Warbler arrives in Mid-May and is found in river valleys and wooded urban areas; Inglewood Bird Sanctuary is a good place to find this warbler.

See if you can find all 5 birds for the month of may; and then let us know about it!!!
