Re: [cobirds] Blue Morph Ross's Goose at Monte Vista NWR

Ooops could have sworn Sterling had that labeled a Ross'

Here's some info I was sent back in 2014 from a birder in SD:

Story and photos: http://wildphotosphotography.com/WildPhotos/RossGoose/BMRoss.htm

And comment: "The dimorphism of Snow Geese is pretty well understood and is a result of a single gene locus where the dark allele is incompletely dominant to the light. In the Ross's Goose, it is not known whether there is a true blue morph or whether these birds are all hybrids or hybrid/backcrosses with blue morph Snow Geese."

Looks like the same type of bird that turned up at Sloan's Lake in 2014 (and spent some time at Wash Park ) that was deemed a hybrid (though some lucky birders got to count it as a Ross'!)

John Sterling found a 'true' blue-Ross' recently out in California:

I have seen only one or two. They are somewhat  unusual.

Yesterday morning (3/13) while admiring the multitudes of Sandhill Cranes at Monte Vista NWR, I came across what I believe is a "blue" morph of a Ross's Goose in my scope. I'm curious what this group thinks. Are these unusual?
