I've got some trimming to do, and I don't want to disturb them. I'm in SW Washington state.
Do you know which species is nesting there? Rufous Hummingbirds should fledge in the next couple of weeks. Anna's Hummers are opportunistic breeders, and often raise more than one brood per year. I've seen fledgling Anna's anywhere from April through November.
I'm pretty sure I've got both. Maybe I'll just spend the time to look for a nest and see if they are still in it.
