Three Possible Cackling Goose, Green
Lane Reservoir (Church Rd.),
Montgomery Co. PA Oct, 17, 2004
At dusk, so light and photos poor. Digi-scoped, so vigneting, and
focus isn't great either.

The three small geese on the left were swimming together the entire
time, more than 30 mins.
Notice short necks, bills, rounder head profile and smaller overall
size.

Three still together.
Here the small top left goose shows some pale breast, slighly squarish
round head.
Good size comparison relative to preening goose immediately in front.

Here one is immediately behind the other. Note stubby bills and
rounder head profiles.
Moving out of sight to the left.
