I spotted the first hummingbirds of 2011 yesterday. Well, technically the first spring hummers. We had a wintering rufous that was wintering in the garden until the 3rd week of January at which time he took back off for the west coast.
The returning hummers are a little later in arriving this year. Usually I see the first hummers around the first or second week of March. Yesterday was the 26th. I'm positive one was a ruby-throated hummingbird and the other was a black-chinned hummingbird. It's interesting that I first saw them both yesterday, but that's how it was.
I snapped a photo of the black-chinned hummer this morning. Here he is working his way around the newly-blooming orchid tree:
