This photo from the gallery is the Opus image for http://www.birdforum.net/opus/Grey-crowned_Warbler. The possibility has been raised that it might instead be Bianchi's Warbler.
To my mind, the split probably happened after the upload of this image, so the original id might not mean that much. I have no experience with either species, nor do I have a field guide showing any of these. Any good answers
