Small and in great numbers.
(Seattle, WA, USA)
I live in Western Washington. The birds I saw are often in our yard and dart around in an almost un-bird like manner. They tend to stay very close to the ground and there are usually quite a few of them out at one time. They are very small, small enough to fit into the palm of my hand. Their color is a grayish brown and they have small curved beaks. Their bodies are very round. I believe their eyes are black or brown, but I may be wrong.
