We have Anna's, Allen's, and Black chinned hummers here year round, so the feeders are always out. Rufous pass through on their way north, but it's almost impossible to tell them apart from the Allen's. They nest here during the cool months, when flowers are scarce, so they need the sugar water. During the winter I watch a live feed (Phoebe Allen.com) that a gentleman in Irvine (about 15 mi. south) provides. It's fun to watch ,and has some interesting info. Phoebe is sitting on her last clutch of eggs for the season right now.
