Warbler Guy, have Dusky Warbler and Arctic Warbler ever been seen in California?

(above, Arctic Warbler, via wikipedia.com)

Joey (in New York, NY), at least 10 accepted California records exist for the Dusky Warbler, per the judgment of the California Bird Records Committee. The same committee has agreed that at least four past Arctic Warbler sightings are valid.

A good book to obtain for “hovering and gleaning” this information:

Rare Birds of California. 2007. Western Field Ornithologists. See: westernfieldornithologists.org

(Updates for new accepted records are online at:

Warbler Guy, I think I just saw an Orange-crowned Warbler (OCWA) in my yard here in S. Carolina. Is that possible (on October 15, 2013)? Migrating warblers includes Orange-crowned to the East? Orange-crowned remain in the East during the fall-winter?

Josie, indeed, please see the map, below, given the non-breeding season range in ORANGE COLOR, below) from the Field Guide To The Warblers (Jon Dunn and Kimball Garrett, Houghton-Mifflin, 1997), it’s likely your ID was correct. (Please email me and I'll send you a PDF of the OCWA range map that shows its non-breeding season presence in the East/Southeast USA....I will upload this map soon here. My email: danieledelstein at att dot net (You need to type the @ symbol and dot, of course.))

Kudos on you.

Correct me if I’m wrong, readers, but I also have seen OCWA during even later periods (Nov. – Jan.) in the East, including MD and NY.....as it sometimes lingers (and/or overwinters?) into the late fall (and winter?) within the mid-Atlantic and lower N.E. states, based on my experience of living in the East long ago.

(Please feel free to make a “comment,” below, readers, relating to this issue...I’d appreciate feedback.)
