Sunday 1 April 2012: Progress: Bushtit nest
We haven't seen any babies poking their beaks out of the nest yet, nor heard any desperate cheeping. But the nest is decidedly fatter. The parents continue to bring lichen and moss and feathers home. I do hope we'll be able to see the babies - it seems they'll be so far down in the "tube" of the nest.
Slideshow here with a few more photos, the nest, the pair and a photo of the nest two weeks ago for comparison.
