THIS WEEK at HILTON POND |
12th ANNUAL YORK/ROCK HILL an 11-year average of 998. Sponsored locally by Hilton Pond Center for Piedmont Natural History, the annual York/Rock Hill Christmas Bird Count (CBC) began early on 21 December 2002--the first day of winter--with a magnificent full moon setting against a crystal-clear sky. For this 12th year of the count, six intrepid birders met before dawn in Rock Hill before scattering across central York County. Veteran participants Susan Holland (6th year) and Faye Metzl and Bob Olson (8 years each) joined Count compiler Bill Hilton Jr. (12 years) and newcomers Lloyd Moon and Bill Powell to inventory all the birds they could find in a 15-mile diameter circle with its center near Northwestern High School. Joe DePriest, reporter for The Charlotte Observer, accompanied one of the field parties for the morning hours. In all the survey teams counted 2,334 individual birds--well below the 12-year average of 6,843--and 70 different species, compared to an average of 65. The 12th annual count turned out to be the third best in species totals; the highest was 2000 with 80 species. (Approximately 125 species of birds might reasonably be expected in York County in winter.) The individual total was the second lowest over the 12-year span of the count, due largely to the absence of any large flocks of blackbirds or American Robins. (Last year's total of 1,915 individual birds was the lowest ever.) The 2002 count produced no new species, but record highs were tallied for seven species: Ring-necked Duck (19), Southern Bald Eagle (2, one adult and one immature), Gadwall (3), and Osprey (3), plus--thanks in part to a newly discovered power-line right-of-way--three sparrow species: Chipping (103), Field (58), and Song (47). Two species--Horned Grebe (4) and Eastern Phoebe (10)--tied records for total individuals seen. This is only the second year the count has produced Ospreys, and Southern Bald Eagles were seen for just the fourth time. One of this year's surprises was an immature Red-headed Woodpecker eating acorns near the extreme eastern edge of the count circle in a York subdivision; this species is seldom seen except at the Winthrop University farm in Rock Hill. We continue to lament the demise of our local Turkey Vultures and Black Vultures, which used to be two of the most commonly reported species on the York/Rock Hill CBC. A visit to the York County landfill was sure to produce several hundred of these scavengers, but when the county moved to a containerized garbage transport system in the mid-1990s, the bottom fell out of the resident vulture population. Even garbage-picking Ring-billed Gulls were few and far between at the landfill in 2002; only 30 were seen--compared to about 3,000 in the count's first year (1991). Also missing in 2002 were any vagrant hummers; two Rufous Hummingbirds spent the entire winter of 2001-2002 within the count circle and one was tallied for last year's CBC. We are still amazed that over the York/Rock Hill count's 12-year history we have never spotted a Northern Bobwhite, and that we almost never hear or see any owl species. If you're interested in helping survey and learn about Piedmont birds, our count is always the Saturday before Christmas (unless that day is Christmas Eve), so get out next year's calendar and pencil it in for 20 December 2003. Maybe you'll be the person that spots that elusive bobwhite at Hilton Pond Center or hears a Great Horned Owl elsewhere within the territory that makes up the York/Rock Hill Christmas Bird Count.

SIGHTINGS OF INTEREST --A heavy half-inch of rain on 19 Nov created enough run-off to further relieve drought-depleted Hilton Pond. It is now only about 18" from capacity, after being down almost four feet at late summer.
