Over 4,000 Birds Banded
The seventeenth consecutive year of fall banding at the
Kaiser-Manitou Beach Banding Station began on 13 July and
ended on 13 November 2002. Banding was conducted by licensed banders Elizabeth
Brooks, Jon Dombrowski, Kristina Hannam, Erin Karnatz, Robert
McKinney, David Semple, Susan Smith, John Waud, and Martha
Zettel.Banding
assistants were Jessie Barry, Chara Batchelder, Kelly Dockery,
Luke Donius, Charley Eiseman, Pat Lovallo, Anna Ludi, Cindy
Marino, Doug Smith, and Chris Villone.
Banding was carried out every day between 26 August and
11 October, except for 27 September when the remnants of
Hurricane Isidore dumped heavy rain on the area. Banding was also conducted on nine days prior to and 13
days after the intensive banding period, for a total of 67
days.
There were 4,098 birds banded of 90 forms. Three male and five female Ruby-throated Hummingbirds
were released unbanded. The season’s capture rate was 30.1 birds/100 net
hours, barely half what it was last fall (58.1 b/100 nh). Yellow-billed Cuckoo, Yellow Palm Warbler, and
Nelson’s Sharp-tailed Sparrow were new species for the
cumulative fall list that now stands at 120 forms.
The best day was 8 October with 291 birds banded, 75%
of the total being Ruby and Golden-crowned Kinglets, Hermit
Thrush, and White-throated Sparrows. Days with 150+ birds banded were 184 on 29 September,
184 on 6 October, 183 on 9 October, 170 on 25 September, 164
on 3 October, and 156 on 4 October. By contrast, there were eight days in fall 2001 when
over 200 birds were banded, including one with over 300 and
one with over 400 birds handled. The greatest species diversity occurred on 4 October
when 33 species were banded.
Up to 45 twelve-meter nets and four six-meter nets were
used, most in the same locations as in previous years. Included in the 44 twelve-meter nets were six
double-high net assemblies. Capture time (hour after sunrise to the nearest 0.5
hour) and net location were recorded for each bird handled. Total net hours (13,623.15) was the second highest in 16 years (range 714 in 1988 to 14,518
in 1999). The birds/100 net hour capture ratio in fall 2001 was
30.1 (15-year average = 64.6; range 40.0 in 1994 – 98.0 in
1988).
The hatching year percentage of all birds banded was
81.5% (eight-year average = 83.6, range 74.5 – 92). Species banded in record-high numbers in fall 2002
included Brown Creeper, Gray-cheeked / Bicknell’s Thrush,
Gray Catbird, Western Palm Warbler, Ovenbird, Mourning
Warbler, Fox Sparrow, Song Sparrow, Lincoln’s Sparrow, and
Baltimore Oriole. Northern Mockingbird was captured for only the second
time ever in fall. On the negative side, Rusty Blackbird was missing after
being captured in 15 of the past 16 years and House Finch was
missing for the first time since 1989.
It was a frustrating fall with day after day of hot,
sunny weather with winds from the southwest – fine spring
banding conditions! Nets had to be closed within 3.5 hours of sunrise on
many days because of the heat and humidity. And when a cold front came through, it was short-lived
and birds seemed to move right on past the lakeshore.
EDUCATION
AND RESEARCH
Four students from the Rochester Institute of
Technology successfully completed a five-week, 1-credit Bander
Training Course at the Observatory. They were: Bryan Correa-Berger, Ruthanne Hoffner, Brian
McGrath, and Peter Mulroy.
Dr. Kristi Hannam, Assistant Professor of Biology at
SUNY Geneseo, and SUNY Brockport graduate student Brendan
McCabe conducted pilot research projects at the banding
station this fall.
From 13-15 September, the Observatory hosted a North
American Banding Council Bander Certification Evaluation
Session for the Eastern Bird Banding Association. The successful candidates were David Hauber (Coudersport,
PA), Erin Karnatz (Batavia, NY), and David Semple (Rochester,
NY). Participating Trainers were Betsy Brooks, Mary Doscher,
Sara Morris, Bob Mulvihill, and Bob Yunick.
Students from Kristi Hannam’s “Animal Behavior”
course at SUNY Geneseo spent a half day at the banding
station, as did students from John Waud’s “Great Lakes”
course at RIT. Girls from Girl Scout Troop #814 of Hilton as well as
many individuals visited the banding station on an informal
basis. Pat
Lovallo presented a program on bird banding as part of the
Preserving the Earth Through Education workshop at Brighton's
French Road School.
RECAPTURED BIRDS
There were over 1,028 birds recaptured during fall
2002, and they were all measured, fat-scored and re-weighed. Twenty-two percent of the same-season recaptures were
White-throated Sparrows.
ECTOPARASITES AND ABNORMALITIES
Avian
Pox lesions were found on three Hermit Thrush, an American
Robin, a Magnolia Warbler, a Black-throated Blue Warbler, a
Common Yellowthroat, and six White-throated Sparrows. Hypoboscid flies were found on a Hermit Thrush, a Song
Sparrow, and two White-throated Sparrows. Ticks were discovered on a Gray-cheeked Thrush and a
Lincoln’s Sparrow. A
12.5 mm diameter tumor was found on an American Robin’s
abdomen and a pea-sized tumor was found on the foot of a Field
Sparrow. Three
White-throated Sparrows, a Gray Catbird, and a Warbling Vireo
had bill abnormalities.
SEASON
HIGHLIGHTS
Highlights of the fall 2002 season included long walks
with Delaney in her stroller; Ann Adams’ expert electrical
work; all the gasps over the freshly housecleaned banding lab;
releasing a Monarch Butterfly tagged by Cindy Marino; a visit
from Bander Training Class grads Julie Freeman and Bill
Michalek; watching Karen Taylor revive a Blackpoll Warbler
with her sugar water feeder; Chris Villone’s sprint to the
net for the Yellow-billed Cuckoo; dry net lanes; the beautiful
Red Bat; the excellent captures in the field nets; a Marsh
Wren and Nelson’s Sharp-tailed Sparrow in the same morning;
the excellent Rockafellow digital photography; the
Sharp-shinned Hawk that was the first bird for the RIT class;
Greta’s good humor over her ‘catching net’; and the
eagerness to learn and enthusiasm of all the new scribes.
