"work work"
The Wilson's Phalarope was first described in 1819 by Louis Jean Pierre Vieillot, a French ornithologist. Its common name commemorates the American ornithologist Alexander Wilson.
The draining of prairie wetland breeding habitat and the diversion of water from major staging areas pose threats to this colorful shorebird.
This bird is the largest of the phalaropes, and is often very tame and approachable. Unlike the other phalaropes, this species does not have fully lobed toes and so rarely swims, spending no time at sea.
A group of phalaropes has many collective nouns, including a "dopping", "swirl", "twirl", "whirl", and "whirligig" of phalaropes.
