Annual Banding Events Capture New Records
This year’s two bird banding events held on
Saturday, 10 May, 2003 (the official International Migratory Bird Day),
and our annual Bird Banders’ Jamboree on the weekend of May 17 – 18, were
very successful in obtaining birds and educating the public about the
needs of neotropical migratory birds. Pat Fisher and Ginny Halverson were
again invited to bring their "educational birds of prey",from The
Feather, our local wildlife rehabilitation center, located just north of
New London, Wisconsin. Children aged 3 to 84 years were able to see
permanently handicapped birds of prey including an Eastern Screech Owl,
Barred Owl, Great Horned Owl, Red-tailed Hawk, and Turkey Vulture. About
125-150 people attended these events in 2003. Those two weekends reported 127 and 156 birds netted during our annual spring migration banding events
during the month of May. The constant gusty winds prevented us from doing
any netting on May 31, however by the afternoon of June 1, the winds had
dropped to allow us to finish off this spring’s activities and setting new
capture records.
Total captures jumped from 360 in 2002, to
606 in 2003. New banded birds moved from 279 in 2002 to 467 in 2003. As
with most banding activities, as your capture rate increases, so does your
returns and recaptures (R/R). In 2002, we had 81 birds R/R, and in 2003 we
jumped to 139. Our species list also increased from 38 to 48 within this
two-year period. Most of these positive changes can be attributed to the
fact that we increased our effort considerably this year, increasing our
netting days from 4 to 7.5, and our total net hours from 331 to 1425.25.
With the regular participation of our guest banders and their field
assistants, we were able to net mostly from dawn to dusk. The average
number of nets deployed each day also jumped from 12 in 2002 to 15.5 in
2003.
Only 8 species captured in 2002 were not
represented in our nets in May 2003. These included three wood warblers
(N. Waterthrush, Chestnut-sided Warbler, Black and White Warbler), one
Sylviid (Blue-gray Gnatcatcher), one Icterid (Brown-headed Cowbird) and
three flycatchers (Eastern Phoebe, Yellow-bellied Flycatcher, Willow
Flycatcher) Eighteen new species captured during this season include five
Fringillids (Lincoln’s Sparrow, White-crowned Sparrow, Grasshopper
Sparrow, House Finch, Dark-eyed Junco), Tree Swallow, four wood warblers
(Nashville Warbler, Canada Warbler, Palm Warbler, Golden-winged Warbler),
Ruby-crowned Kinglet, four thrushes (Eastern Bluebird, Swainson’s Thrush,
Wood Thrush, and American Robin), Alder Flycatcher, and two vireos
(Solitary and Red-eyed). The most numerous new bird captures include
American Goldfinch (166), Black-capped Chickadee (43), Northern Oriole
(31), Rose-breasted Grosbeak (26), Downy Woodpecker (21), White-throated
Sparrow (19), Blue Jay (17), Chipping Sparrow (16), Common Yellowthroat
(14), Indigo Bunting and Gray Catbird (both 13), and Ruby-throated
Hummingbird (12).
