    2006 September

    Over the course of 25 banding days, and with 7,180 net-hours of effort, we banded 3,379 birds (and recaptured an additional 356) of 87 species in September, for an overall capture rate of 47 birds per 100 net-hours. Our highest daily banding totals during the month occurred on 9/15 (229 birds banded) and 9/16 (245). Forty or more species were banded on 9/19 (42 species), 9/20 (40), and 9/29 (43). Magnolia Warbler easily topped the banding totals in September (401 banded), with the remaining nine of the month's "top ten" as folows: Swainson's Thrush (250); Gray Catbird (188); Common Yellowthroat (184); American Goldfinch (179); Ruby-throated Hummingbird (167); Hooded Warbler (167); American Redstart (150); Red-eyed Vireo (1372); and Tennessee Warbler (102).
