The National Geographic Field Guide to North American Birds reports that Greater White-fronted Geese occasionally hybridize with Canada Geese. This photo of a goose seen feeding with a flock of Canada Geese in Dean Park on Wednesday would seem to fit the description of such a hybrid. Is it a rare wild hybrid? Not likely, given the fact that there were two present - as can be seen in the photo- that fit the description. (report and photo from Bob Ricci).
