Rare Warblers on the CBC Take 2

The following have been seen in this past week within the Tucson Valley CBC circle:

A Black-and-white Warbler at Sweetwater Wetlands in the winter of 2010-11

Black-and-white Warbler
Chestnut-sided Warbler
Yellow Warbler
MacGillivray's Warbler
Townsend's Warbler
Black-throated Gray Warbler

Wow!

And I guarantee that hasn't been all of them. There's quite possibly a Wilson's Warbler at the Reid Park Zoo, as one has wintered there in recent years and an adult male was eBirded from the exact same location on a suspiciously late date in November.

We've recently had some nice warblers discovered on count day, such as Ovenbird (two years ago), Palm Warbler (last year).

Also consider the warblers discovered only in the few days or weeks after the CBC in past years: Black-throated Blue Warbler, Hooded Warbler, Pine Warbler – almost all certainly birds that had been on winter territories for some time.

So get out there and bird all over the place – parks, alleys, pockets of trees around apartment complexes and office buildings, washes, and all along the Santa Cruz River. Your scouting efforts don't have to be in your assigned area. And have fun!
