Stacked Snow Geese

Stacked Snow Geese
Originally uploaded by Fort Photo

"50,000 Snow Geese winter at the Bosque del Apache National Wildlife Refuge in NM. Seeing them at a distance they may look like identical white birds but upon closer inspection there is a great deal of variety such as the slightly darker juvenile (white morph-immature) flying on top in this image. Also roughly 5-10% are not Snow Geese at all but are the very similar looking Ross's Geese. "
