Jackson Bottom birds: February 27-March 5, 2010

Willows and Osoberry and Salmonberry are blooming, as well as some non-native flowering cherry or plum trees, such as the one in the photo above. The grass is greening up. But most other trees and shrubs are still bare sticks with, perhaps, some buds just starting to form.

TREE SWALLOWS returned in force this week. A single BARN SWALLOW noted at the end of last week was present early this week. It is about 5 weeks early, generally not arriving until the first week of April. A VIOLET-GREEN SWALLOW was spotted March 3.

A EURASIAN-COLLARED DOVE put in an appearance for a few minutes at the bird feeder this week. They are still only occasional visitors to the Preserve; the wetlands habitat is not really ideal habitat for these recent invaders.

Amazingly, MARSH WRENS are singing away and we found a recently built nest. This is probably a "dummy nest" as described in this article in the 1990 issue of the Auk.

The Northern Shrike is still being seen near the Dogwood Viewing Area on Blue Heron Trail (map; key). The patagial marked Red-tailed Hawk seems to have taken up residence. The eggs of the Great Horned Owl must just about be ready to hatch.
