Video clip of the intermediate plumaged phoebe singing

I took this video clip yesterday (and it has taken me until today to get it in a format for uploading) of the possible hybrid Black X Eastern Phoebe that I posted about in my last posting. The song the bird sings is consistent with the primary song of the Black Phoebe and the calls it emits also sound like Black Phoebe calls. As it flies off I lose it briefly then get on it again. At the end it flies after it's apparent mate which seems likely the reason for the fluttering of it's wings in the display before it takes off. SeEtta
