Iceland: several places, 2012: July.
U.S.A.: Nome, 2015: August.
Distinctive in breeding plumage, with the dark red of the throat being distinctive.
I think this one is on a nest as it was in the same position the previous day.
Their bill is slightly upward pointing.
They're a large bird so it takes a bit of a run to take off.
The underwings are whitish.
Take-off accomplished with a bit of a splash!
