There are no birds (almost!)

HI . . .
Regular readers of CarolinaBirds, BirdBand, and/or BirdChat will
recollect that I have made several postings over the past few months
lamenting the dearth of birds at Hilton Pond near York, South
Carolina, and in the central Piedmont.
Some of you poopoohed me privately and said it was just all the mild
weather we were having and that the birds were out dining on natural
foods and that they'd be flocking to the feeders at the first sign of
bad weather (see below). Nonetheless, I was confident the weather was
only part of the problem and felt somewhat vindicated when I compiled
the York/Rock Hill Christmas Bird Count. This year's count had only
2,890 individuals--by far the all-time lowest number of individuals
(7,673 is average, 12,000+ is the high).
What I haven't revealed until now is that my 1999 banding totals at
Hilton Pond were also miserably low and bore out my contention that
"there are no birds." My 18-year average for birds banded in a
calendar year is 2,008 individuals and 71 species, and I only managed
to capture 1,359 birds from 71 species in 1999. (My record high is
4,061 individuals and 95 species in 1991.) Some of this drop was due
to severe declines in "winter finches" (House Finch, Purple Finch,
American Goldfinch, and Pine Siskin), which make up 44% of the 36,170
birds banded since 1982 but that have not occurred in big numbers in
several years. In addition, the migratory warblers were drastically
under-represented in both spring and fall migration in 1999, and even
common residents like Blue Jays, Northern Mockingbirds, and Eastern
Towhees were well below their average annual numbers.
So the bad news is that bird numbers really do appear to be down, as
documented by observation AND banding results. The predicted droughts
of 2000 and a possible return of the dreaded El Nino certainly won't
help bird life in the Carolina Piedmont--nor will the global warming
trend that is being coming more evident with every valid data set.
The good news is that last week I finally got my first Purple Finches
of the winter, and now I'm up to seven for 2000. (I get my rays of
sunshine where I can and choose to ignore that my annual average for
PUFI is 269, with a record of high of 697 back in 1987!)
And, just to admit that "bad" weather can sometimes be "good," last
night's sleet storm did indeed bring in the first American
Goldfinches of the year (six of them), and, even more exciting, the
very first Pine Siskin since I banded six of them back on 10 January
1996. (The last "big" siskin year was 1988, when I banded 252, but
the record was 482 in 1987.)
Even more exciting is the fact that along with these "new" finches,
I've retrapped several "old" ones in the past week, including Purple
Finches (two fifth-year, two after-fifth-year, and one sixth-year),
Dark-eyed Juncos (one after-third-year, and one fifth-year),
White-throated Sparrows (one third-year, one fourth-year, and one
sixth-year), and an American Goldfinch (fifth-year). Several of these
had been retrapped one or more times after their original bandings
that occurred as early as October 1995.
So, for those of you who've read this far, my news is a mixed bag.
Let's hope the bag is half-full instead of half-empty! :-)
Happy Birding & Banding!
BILL
