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.
NatureMapping observations reported by townships throughout the year.
This ibis occurs year-around along both Mexican coasts. It breeds through the mid-section of the United States. This species is a rare but increasing visitor in Washington on both sides of the Cascade Mountains, mostly in May and June. Sometimes it appears in large flocks. Several pairs attempted nesting at Lake Kahlotus (Franklin County) in 2001.Text edited by Gussie Litwer
