Our 16th fall banding season took place on 43 days from 21 August to 3 November. An average of 16.5 nets (12 meter equivalent1) were open an average of 4.75 hours per day. The head bander was ill for several days early in the season, but this period coincided with very hot, dry weather with little bird movement. In fact, it was the unseasonably hot weather 2 which extended well into October, that was the hallmark of fall 2007. August, September, and October all had above-normal temperatures, with October averaging over 7 degrees above normal, the 6th warmest on record for Detroit. Rainfall was below normal for every month from June through October, with the exception of August. However, a large percentage of August’s rainfall fell in one day (19th-20th), and subtracting that, rainfall was normal. For more on weather effects, see numbers and trends, below.
We ended up banding 1230 new birds and had 163 recaptures of 69 species (includes three species released unbanded: Ruby-throated Hummingbird, House Sparrow, and European Starling). A total of 1499 birds were netted (this includes birds released unbanded). Our capture rate was 46.7 birds per 100 net-hours our fourth lowest.
