On May 16, I heard an Ash-throated Flycatcher calling on the wooded hillside to the east of Fox Pond. About 30m from the trail, I noticed a snaggy-looking, vertical limb with a broken/open top and a woodpecker hole not far below (two different entrances for the same cavity). I wondered if perhaps the flycatcher might be nesting in there. Within a few minutes, an Ash-throated Flycatcher appeared on the rim of the broken top. It had a nice piece of fur in its bill. Eventually, it flew off. Perhaps it was disturbed by my presence. I waited for awhile but there was no more activity at the tree. I revisited the same location on May 22 and saw an Ash-throated Flycatcher perched in the same place. After a few minutes, it dropped down into the limb through the open top. Cool!
The photos I've posted are from May 22. Unfortunately, I only got blurry pictures of the flycatcher when it was carrying the fur. Darn!
