Migration Monitoring at TTPBRS-Oct 7-13

October 7-13 was one of our busiest 7 day periods ever at TTPBRS. North winds and rain on the 7th kept the nets closed but census revealed some high activity. Even in the midst of a steady downpour after census it was clear that a substantial movement had occurred. The next day showed that as impressive numbers of kinglets, Hermit Thrush, Yellow-bellied Sapsucker, Myrtle Warbler and several species of sparrow were evident during the morning and afternoon. A total of 205 birds were banded of 28 species and another 135 birds were released unbanded. Birds continued to move through in massive numbers on the 9th as 238 birds were banded and another 124 were released. Only 10 recaptures were recorded on the day which indicated a high rate of turnover and another influx. Intermittent drizzle on the 10th limited our net hours to just 1.5 out of a possible 90 although birds were still much in evidence including the first Pine Siskin of the fall. Continued north winds on the 11th yielded 131 banded and the first flocks of migrant Black-capped Chickadee. We had expected some sort of break at this point but found high numbers once again on the 12th which included 33 Yellow-bellied Sapsucker (2 banded) and 220 Ruby-crowned Kinglet (58 banded). A total of 137 birds were banded on the day. Remarkable numbers of birds were again detected on the 13th with a total of 205 birds banded. There is some early indication that Ruby-crowned Kinglet will surpass Golden-crowned as the most commonly captured bird at the station this fall which would be a first in our three-year history. Overall it was a tremendous week at the Tommy Thompson Park Bird Research Station and we still have a month to go yet!
