At the college where I work there is a pond. Canada geese live around the pond year round. There is also a big white goose that lives there. He has big orange feet and an orange beak, in stark contrast to the numerous grey/black Canada geese. I feel sorry for this white goose because there are no other geese like him around. He's big, kind of fat and cannot fly, unlike the Canada geese. I think he is classified as a domestic greylag goose. Greylags are native to Eurasia and were historically raised for meat. According to this website, the greylag males are white with orange beaks and feet.
Anyway, I've noticed that for the last couple of years, the Greylag goose has been like a "good uncle" to a mated pair of Canada geese. He always helps the pair out by babysitting and watching out for the goslings. But this year, after seeing the goslings down by the pond, I think he was up to something more...a motley crew:
This is dad:
And this is mom:
This Cornell website confirms that Greylag geese can mate with Canada geese.
There are 5 goslings. All are different shades of grey:
I think they are quite beautiful.
