The Washington Gap Analysis Project created breeding bird maps only. The non-breeding birds (e.g., wintering, pelagic (coastal), and birds expanding their ranges) are represented only by NatureMapping sightings.
The Washington Gap Analysis Project could not find any historical research records (i.e., Breeding Bird Atlas, Breeding Bird Survey, Bird Banding and Recovery) for 73 species of birds. The Fulvous Whistling Duck is one of the species.
NatureMapping observations reported by townships throughout the year.
This species is declining in the west and has not been seen in the State of Washington since 1905. It is seen year-around in Mexico, and breeds sparsely in central and southern California. In Washington, one bird shot from flock of ten at Grays Harbor in October 1905.Text edited by Gussie Litwer
