This is an interesting nest that I suddenly noticed right out side my door last week. It just suddenly appeared. At first I couldn't tell if it was made recently or left over from last year, but I I would have noticed it if it had been there for awhile. It's a Bushtit nest and active. Hopefully the local cats will keep out of it and my noisy boys won't scare them away. When the nest is occupied you can see it shaking and hear the couples twittering (or tittering). I plan to continue photographing it in situ with both color and true gray scale film and later when the nest is abandoned ,if it still is whole, I can do a more serious photographic study of it downstairs in my "studio".
