Blue Snow Goose or Hybrid? A Mystery to Me!

A strange white-necked goose swam with the regular Canada geese on Regina's Wascana Lake in late March.

Its head was white, too, and from the shape of its bill, it looked like a Snow Goose to me.

But I know very little about such things...

From what I've read, however, there are two colour patterns of Snow Geese — the white morph and the blue morph.

White is easy: These birds are primarily white.

Blue, less so. These bird are partly white, and partly gray-brown.

(It was the same size as the others on the lake, which looked like small Canada Geese, so perhaps they were Cackling; I don't really know.)

These are my clearest images; not great, but this mystery bird was far across the lake.
