After a wonderful dinner with friends not far from Potter Marsh, we swung by to see what birds we could find. Note the official time of sunset tonight in Anchorage was 10:46. This picture was about ten minutes later.
Here's an arctic tern (as was the first one). They fly between here and Antarctica and back each year. They're such beautiful, sleek birds.
This spot has terns and gulls nesting near each other. Things were relatively calm, when all of a sudden the birds were all in the air screeching and flying this way and that.
And then I heard the unmistakeable croaking sound of a sandhill crane which flew over me, and I'm guessing disturbed the gulls and terns. They're huge birds - wing span about 6 feet, probably a little less than bald eagles (though the
web shows a variety of wingspans for bald eagles.)
[UPDATE May 18, 2014 noon: Edgywytch comments below that sandhills eat tern and gull eggs. The Crane Foundation website linked below says:
"All cranes are omnivorous. Sandhill Cranes are generalists and feed on a
wide variety of plant tubers, grains, small vertebrates (e.g. mice and
snakes), and invertebrates such as insects or worms. Sandhills find
these foods in uplands and in shallow wetlands. Like most cranes,
flightless chicks forage primarily on a diet of insects and other
protein filled foods during their early stages of rapid growth. The
Sandhill's tendency to feed on plant tubers creates conflicts with
farming. Sandhill Cranes are adept at probing in the ground and finding
planted agricultural seeds such as corn. When large flocks of cranes
feed on planted fields, the damage they cause to an unprotected crop can
be severe enough to force the farmer to replant the entire field. "]
Sandhill cranes are another great bird we get to see in Alaska. You can read a lot more about them at the
International Crane Foundation website. I had my telephoto on and finding the bird in my camera and focusing in the fading light was beyond my ability and I'm a little embarrassed by how fuzzy the bird is in the next picture, but it gives you and idea of how big it is. It's the white horizontal line in the picture. I'm guessing it's approach is what upset the gulls and terns. Since its wingspan is close to that of eagles, perhaps they originally thought it might be an eagle. But that's merely a wild guess - you'd think they should have learned to distinguish between the two.
It was pretty far away by the time I got this picture - about 11:05 pm.
