Weekend avian visitors ...

I've been doing an abysmal job maintaining my Birdstack Dashboard (follow the link, or see my sidebar). I know I've seen some interesting birds, but I've neglected to record the observations. I've tried to make up for it by recording this weekend's visitors:

• A pair of green herons, which chased each other around the pond on Saturday evening. I'm not sure, but I think one of them might have been trying to get the other to vacate the premises. The attempt was not successful.
• A sharp-shinned hawk, first heard early Sunday morning in some kind of fracas with some crows. Later, I saw the hawk in a tree and it disappeared after swooping in on its prey.
• A ruby-throated hummingbird, which made numerous visits to the hummingbird feeder today. Sometimes he even stopped to sit on the hook holding the feeder. We only put up the feeder last weekend, and have missed most of hummingbird season. So it's nice to have this visitor before they migrate.

Now I just wish I had a super-duper camera to capture photos of all these! Sigh.
