Subject: [MDBirding] Anomalous White-throated Sparrow with pale bill
Reviewing photographs on Saturday afternoon, April 13 I came across one of a White-striped White-throated Sparrow with a pale almost yellow bill. In addition the breast and belly seem strange -certainly not typical. I'm also attaching the photograph of a more typical White-striped adult taken this morning,which shows the normal dark bill.

Any suggestions? Just an anomaly. Perhaps a hybrid. The one shown in Sibley of a Dark-eyed Junco White-throated Sparrow hybrid has a yellow bill. Also there is, I think, of the possibility of a hybrid with a White-crowned Sparrow.
