Wilson's Phalaropes are generally much more common than the Red-necked
Phalaropes, and will occasionally spend the winter at Obsidian Butte at
the Salton Sea. Wilson's are usually seen in the early spring
and summer before the Red-necked. Look for
Wilson's in April and July in shallow water ponds surrounding the Salton Sea,
like those at Obsidian Butte and Red Hill Marina, and in sewage lagoons, like
the ones s. of Yuma Proving Grounds.
