For willow flycatchers, an endangered species that relies fairly heavily on wetlands and riparian systems, it is often thought that beavers are very important. The picture below is from Carmen Valley in Tahoe National Forest in California. This was a picture I took of a willow flycatcher territory in 2007--he never acquired a female but it seemed like a pretty sweet place to hang out.

Most of the willow is gone or dead, and at least 3 beavers were seen swimming in the area at the same time. So in this case, it seems the beavers did some damage. Maybe its just too many beavers for one area.
Where's the willow flycatcher you ask? Hes still here--I saw him (or at least someone) flycatching like crazy over his new lake front property and hes taken up residence behind where I stood for the photo where there are a few willows in some kind of drainage ditch. I'm curious to see if he stays--but I have no idea why he would. Carmen Valley, in my opinion, has several other great places with more willow that he could occupy. If he is really the same bird--is he that site faithful that he won't move after these drastic changes?
