Kelly, I sat by the feeder all day sling-shot in hand but the bird did not
come back today- darn. Maybe yesterday will be its only visit, who knows.
There are plenty of Golden-crowns here but the other half I though was
White-throated so we would have to get an eastern tweeter to help us, given
the winter they are having there maybe the dry ice won't be needed.

Jim Rising, who is writing a book on sparrows told me that there is one
published report of this hybrid in the literature:

>The only record I know of is an
>"apparent hybrid Zonotrichia atricapilla x albicollis, caught...12
>January 1978" at Dowling, Barry Co., Michigan (Payne, Auk 96:595-599,

>Auk.

If the photos are half decent I may try to publish a small note on this
bird somewhere. It was certainly interesting.
