Staging for Migration

Over the last couple of weeks I have been observing certain species of birds that are congregating into flocks, fattening up on seeds and insects, preparing for winter migration.

This morning we had 50+ Western Meadowlarks in the wildflower field on the north side of Avimor Drive. I have never seen so many together. I can only assume that they gather for migration. Based on location maps, it appears that Western Meadowlarks don't go too far as they can be found along the west coast and the southwestern states year round.

I also watched a flock of Red-winged Blackbirds in the tall cottonwood trees along Spring Valley Creek. Their plummage looked pristine, especially compared to the rough looking bunch I saw a couple weeks ago. Red-wings do winter in Idaho, but they appear to flock together and to be found in only certain locations.

The Brewer's Blackbirds still seem to have a couple of flocks around Avimor.
