A Perfect Swarm
Snow Geese at Middle Creek, PA

(large-size photos)
March 6, 2011

The March 4, 2011, count of snow geese at Middle Creek Wildlife Management Area, Pennsylvania, was 60,000 (down from the 80,000 of a few days ago), fewer than the two previous years, but magnificent all the same. (Tundra swans at 4500 were up, and I have to put up a Middle Creek tundra swan page.)

Click on a photo to see the small-size version (one quarter the file size).

The following shows how a swarm maintains itself: On the left, rows of snow geese lift off from the lake to join those already flying.

Photo note: I used a Pentax K20D, with the Sigma 150-500mm lens, for these photos, taken on 4 March 2011.
