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." -Matt Baker Denver, CO On Monday, March 14, 2016 at 4:27:12 PM UTC-6, Matthew Baker wrote: > > 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: > > https://sterlingbirds.smugmug.com/Recent-Photos/i-NbQ4sVQ > > Matt Baker > Denver, CO > > > On Monday, March 14, 2016 at 1:25:12 PM UTC-6, Ira Sanders wrote: >> >> I have seen only one or two.
