What it sounds like
A nasal clunking "took-took" from the male; a low quack from the female.
Behaviour that gives it away
Feeds by swinging its bill side to side at the surface, straining tiny food through comb-like edges rather than tipping up.
Habitat & range
Shallow marshes, flooded fields, sewage ponds and lake edges across North America.
When you'll see it
Depending on where in North America you are, it is a winter visitor and a passage migrant, seen mainly in spring and autumn.
What it eats
Tiny crustaceans, seeds and invertebrates strained from the water surface.
Did you know?
Its bill carries over a hundred fine comb-like projections along the edges, working like a sieve for plankton-sized food.
