Hidden in Plain Sight

May16

Canada Geese are abundant in Calgary year-round, and for the last month or so they have been nesting in various spots around the city.  Like all birds, they try to find nesting sites that are secure from predators like coyotes.  They will often nest on top of flat-topped buildings, and one of the best locations a goose can find is the top of a large broken tree.

Another good location is an island in a pond or the river.  I’m always amazed at how difficult it can be to see the nesting goose even if it’s in the open like this…

Above, the male Canada Goose stands watch near the nest and is fairly conspicuous on the left-hand side of the gravel bar, but can you see the female on her nest?

There she is, on the right-hand side.

As seen below, it’s amazing how the colour pattern of a Canada Goose can allow it to blend in to its surroundings so that it is nearly invisible…

There are still plenty of geese on their nests in the city.  I just saw my first goslings on Saturday, May 14, about ten days later than usual.  For the next couple of months we will be treated to scenes like this:

Swainson’s Hawk

May15

While we were at Inglewood Bird Sanctuary doing our Big Sit, we came across a very interesting sight. There, perched on the ground, maybe ten feet off the path, was a dark-morph Swainson’s Hawk. The dark-morph Swainson’s Hawk has a dark-brown colour over most of its body; the more common light morph has a brown bib contrasting with white underparts. This particular hawk had a Richardson’s Ground Squirrel clutched in his claws and was regarding all the photographers and interested visitors with a haughty look.

This Swainson’s Hawk intrigued many visitors to Inglewood Bird Sanctuary.

And there he sat; for over an hour we were told, he had stayed in the same spot. He finally got tired of all this hustle and bustle, deciding to try to find a quieter place to enjoy his meal in peace. However, he had not counted on catching such a heavy meal…

 Attempted take-off

After he couldn’t achieve lift-off by taking a running leap, he tried a different tactic: taking off from the spot where he stood.

Flap!!!

Well that didn’t work either…

The hawk then decided that, seeing as he wasn’t going anywhere with his meal, he might try to eat it right then and there. And that’s what he did. He hopped back a couple of feet with his meal, to a slightly more secluded area and began to eat.

 Here, he shields his meal from potential thieves.

Hopefully his meal didn’t weigh him down too much after he ate it; otherwise, he might not be able to take off again!!!

Big Sit results

May14

A very windy morning was spent down at Inglewood Bird Sanctuary by us three bloggers; several people came by to join us. The large gusts of wind kept the birds down and hard to hear but we still had some great birds. From 8 -10 a.m., we counted birds down at the river recording 24 species of birds.

  1. Canada Goose
  2. American Wigeon
  3. Mallard
  4. Common Goldeneye
  5. Common Merganser
  6. Double-crested Cormorant
  7. Osprey
  8. Swainson’s Hawk
  9. Merlin
  10. Spotted Sandpiper
  11. Franklin’s Gull
  12. Rock Pigeon
  13. Belted Kingfisher
  14. Northern Flicker
  15. American Crow
  16. Common Raven
  17. Tree Swallow
  18. Northern Rough-winged Swallow
  19. European Starling
  20. Yellow-rumped Warbler
  21. Song Sparrow (heard 5 minutes before 8a.m.)
  22. Red-winged Blackbird
  23. Common Grackle
  24. Brown-headed Cowbird

At 10a.m., due to the frigid wind, we moved base to the Walker house ( we were there 10:30-12:15) where we added:

  1. Cooper’s Hawk
  2. Red-tailed Hawk
  3. Black-capped Chickadee
  4. Chipping Sparrow
  5. House Finch

All and all, not a bad morning to celebrate World Migratory Bird Day; a grand total of 29 species of birds from within the count circles. There were also some good birds from outside the circles; right after we called it a morning and took down the circle, an American Kestrel showed up. We also saw White-crowned Sparrow, White-throated Sparrow, House Wren, Warbling Vireo, Northern Pintail and a Barn Swallow. One of the highlights was a Swainson’s Hawk less than twenty feet off the path, with a kill. A story will follow shortly!

Bird Songs 101

May14

Ever heard that beautiful song coming from deep inside a dense bush, but don’t know what exactly is the source of that amazing sound?  You can check out this great site to help you match the song with the bird.

http://www.natureinstruct.org/dendroica/

The Blackpoll Warbler gives a very high-pitched song that can be inaudible at times.

Dendroica.com is a great site; whether you are a novice and just learning the songs, or you are a seasoned pro and brushing up for the spring migration. Photographs of the bird are provided on this site, as well as a description of the song or call and then the song itself. Once you have gotten familiar with the sounds, you can go out into the field with this newly-found or rediscovered knowledge, and be able to identify that beautiful song coming from deep inside the bush.

Down at the pond

May13

Ponds can be a great place to see birds. They provide a home to not only birds, but many plants, mammals, insects, fish; the list could go on forever! The key factor is the water. Water attracts birds almost without fail; they need it to bathe, to drink and to keep cool. You can see birds at big lakes, such as Frank Lake, or you can see birds at small ponds, like the one close to my house.

 A male Red-winged Blackbird calling. These birds are common at ponds that have rushes and reeds along the banks.

At my local pond, which sits on the Willow Park golf course, you can just about always see Mallards, Common Goldeneye, American Wigeon, Redheads and Red-winged Blackbirds. Lately, there has been a pair of Canvasbacks on the pond as well. Ponds where you are likely to find birds need to be the right types of ponds. Several characteristics define a good pond, including: moderately deep water, plenty of vegetation, both on and under the water, reeds around the banks and good, fairly undisturbed nesting spots. These factors can make ponds irresistible to many birds.

The male Redhead is a striking duck with its rust red head and dusky grey back.

Do you have a pond near you? If you do, go check it out, you never know what you might see!

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.
