I'm not sure, I haven't seen him in the bright light, but I think I have a Blackchinned Hummer at my feeders. He just doesn't look like he has the red throat, but the three times Ive seen him he was in the shade turned profile to me so it's hard to tell. I looked him up in my book, it shows we shouldn't have that species here, but the boundry is so close, I'm thinking I may just have a very adventurous one:). I did see a female chase him off the feeder. He flew up in the tree in my garden and sat and watched her at the feeder, and you could tell from the way she turned her head she was keeping an eye on him:)

She will chase that one away. Could it be possibly a migrating bird? I don't know much about them. We only have Ruby's here and I don't even see them often, yet... I'm still working on that. :) Have you seen the bird again, yet?
