11/20/2011 Color-banding

Summary from the Southwick Site, written by Chris Southwick, edited by Mary Huff

Despite the fact that we didn’t start banding until 0920 due to the cold–it finally warmed up to 38 degrees F–we still managed to catch 37 birds with less than two full hours of open nets.

Highlights included a Hatch Year (HY) Downy Woodpecker (DOWO) male; a HY Hairy Woodpecker (HAWO) male; and a male and a female Red-breasted Nuthatch (RBNU) caught at the same time, which enabled us to take great comparison photos of both birds side by side–see below. For both woodpecker species, note the dull brown primary coverts as compared to the rest of the wing. Also look at the difference in bill length in the profiles. The tails are also distinctly different colors–not that you can see the open tails as they are hitching up a tree…

The species list and totals for the day:
Bushtit: 6 new (1 Female)
Black-capped Chickadee: 2 new, 4 recaptures
Chestnut-backed Chickadee: 1 recap
Oregon Junco: 11 new, 8 recaps
Red-breasted Nuthatch: 2 new
DOWO: 1 new
HAWO: 1 new
Purple Finch: 1 new

We had a fifteen minute period of nets closed due to quantity of birds waiting after bagging a flock of Bushtits and a flock of Oregon Juncos virtually back-to-back.

Another note: I have seen a dramatic decline in the Song Sparrows using my yard, and a smaller decline in the Spotted Towhees using my yard since my next-door neighbor stripped his yard. The plus side is that I now have two Pacific Wrens that have moved into my inner back yard, and are using the ferns and other natural cover.  I can’t hardly wait until spring to hear them sing!
