WHITE-WINGED TERN Chlidonias leucopterus
The photos show adult White-winged Tern at Arcata HUM 25 June 1996 (above left)
and the first-summer White-winged Tern at Moss Landing MTY 21 Sep 1999 (above right)

The WHITE-WINGED TERN is an exceptional vagrant to California with but two records to date (2003). The first was an alternate plumaged tern in Humboldt Co., the second a first-summer bird in Monterey County. I've seen and photographed both of them.

All of my California records are listed below. Those preceded by H were found or co-found by me personally; those preceded by K receive some partial credit (e.g., I was involved in sorting out i.d. of a previously discovered bird or refound a vagrant that had been thought to have left). These are my personal White-winged Tern records:

6/25/96    Arcata marsh HUM     adult in alternate plumage; details in notes, photos.
9/6&11&21/99    Elkhorn Slough, Moss Landing MTY    first-summer bird in wing molt present on "pond #3" adjacent to Moonglow Dairy since August, but not identified until 6 Sep (by Ed Kwater; who called me to come verify it) and then it remained to mid-October. I studied it at length three times and took photos; by my 21 Sep photos it had mostly completed wing molt [photo sequence on "Monterey highlights 1999" page]. I have extensive field notes as well.
