Bluebirds and Cold Rain


Jamie and I arrived at the Blue Ridge Center on Saturday morning, the 14th, ahead of the coming Nor'Easter , in time to check on the Bluebird nest boxes on the Farm Loop trail. We saw Bluebirds perching on wire fences, in the trees and even a pair on a box, but we didnt see any finished nests in the boxes. One box held a single 6" long white chicken's feather...probably brought there by a Tree Swallow. I've wondered...do they collect feathers for their nests off the ground, or do they pluck them out of the air as the discarded feathers of other birds are lifted by wind gusts ? Last year, there were lots of Tree Swallows in the boxes...out of the 12 boxes available, I think 7 were occupied by them. Amazing creatures of the air, and brave defenders of their nests...they'll swoop repeatedly at your head, until you are sure that it is going to take a piece of you ! Kaufman's bird book describes their call as "liquid twittering"......can't think of a better way to describe it. I also read that although most of their diet is flying insects, they will also eat berries.
