Atlantic Flyway review: Piedmont-Coastal Plain, Region IV, Fall 1999: Robbins Nest, Laurel, MD (390-0765)

Abstract

This is the first of three stations along the Patuxent River. Elevation here at the edge of the Piedmont ranges from 265 ft at the house to 160 ft at the river. In spite of easterly winds and heavily overcast skies from Hurricanes Dennis, Floyd, and Irene, we suffered from drought all summer, not rain. We had only about two inches each in June and July, 4.55 in August, then a whopping 16.03 in September, and a normal 3.46 in October. This station operates all day on weekends, but only before and after work on other days. Net-hours were 5% above the 26-year mean of 3655, but way down from last year because other commitments kept me out of town on several weekends. I had only 14 days when I could net all day. Although the most birds were banded on opening day, the most per net-hour were on 19 and 15 October and 23 September. The nets caught 26 returns from prior years, the oldest being a seven-year-old Blue Jay and a seven-year-old cardinal. To illustrate how biased a sample one can obtain from netting, I captured only one junco in the nets, but caught 47 of them in baited traps on our deck. Other species taken only in the traps (and not included in the totals) were Mourning Dove, Chipping Sparrow, House Finch, Pine Siskin, and American Goldfinch.
