Birds I'm Watching: Odd Bushtit Behavior (March 31, 2014)

Spent the day indoors today (March 31, 2014) because of the rain, but I didn't have to go out to do some bird watching. The birds came to me--one bird, anyway--a female Bushtit that spent several hours flitting back and forth through the dense plant growth near one of my living room windows. I watched the bird on and off for quite some time. No sign of nesting material, but it was clearly occupied doing something--and alone, not in a flock. She pecked at the window repeatedly and for no apparent reason, making a circuit of a fixed number of perches near the glass over and over again. She was loud enough that I could hear her from upstairs. I'm wondering if she's looking for a nesting site? I got some good close-up photos of her. I wonder what she was up to? Perhaps just pecking at her reflected rival in the glass....
