A bright yellow (male) American Goldfinch pull out a bull thistle seedhead
A bright yellow (male) American Goldfinch sits on a bull thistle with thistle down in its beak. A bee with obvious pollen basket is getting nectar from a purple bull thistle in the background
Side view of an American Goldfinch sitting on a bull thistle that's gone to seed. The thistle down forms a comical cone on its beak
There's a reason American Goldfinches are called "thistle birds"! As #granivores, their main food source is seeds; the #bullthistle provides these and also thistle down for their nests right at the time that they are breeding (now!)
