A Blue/Dark Morph Ross's Goose at Bosque del Apache NWR?
 

Today I went hunting for the Ross's Goose I saw a couple of days ago. Today, I found another one, but this one is different. It has a white belly and the bill shape is an exact match for a Ross's Goose. I think the goose I saw before is a hybrid and that this one is a true dark/blue morph of the Ross's Goose.

Bill like a Ross's Goose.

This one has a white belly.


Compare bills on white morph Ross's Goose and the blue morph Ross's Goose. Nearly identical, and there are faint tubercles on the blue morph bill.
