观察细节
Observed in field with large flock of Canada Geese. Birds have characteristics of Ross Goose: smaller in size than the CAGE (see picture for size comparison), very white body, stubby bills, round heads and lack of grin. Details attached to pictures. Birds did not move noticeably for over two hours (observed twice). Were not seen walking or flying. No vocalization NOTE: Pictures could be better (especially bills). When taking pictures I was only considering Snow Geese. Photos have not been edited NOTE #2: Changed designation to Snow/Ross's Goose, per recommendation of reviewer, as blue caruncle is not readily visible in photographs. Birds are definitely not Snow Geese, but may be hybrid
