Rare but annual winter visitor on larger lakes and reservoirs in Maricopa County.

Broad, smooth rounded head, lacked peaked crown of Lesser Scaup, also a relatively broader bill. Observed in flight briefly, during which it showed extensive white extending into the primaries. Also showed wider white stripe in the secondaries than Lesser Scaup.
