Thanks so much Marko for choosing my image and thanks to Iggy for nominating it in the Members Choice. I know Marko isn't much of a "birder" so I will cut him a little slack, buts its not a hummingbird, its an Eastern Phoebe
As an update that cowbird chick turned out to be a female who I still see quite often around the feeder and the Eastern Phoebe went on to have another clutch of 4 (but with no cowbirds this time)
