Last week, as Matt reported here, came the great news that male Kirtland's Warblers had returned to the site in Adams County here in Wisconsin where they fledged 10 young last year. Now we've received the even better news that at least four females have arrived as well.
According to Joel A. Trick of the U.S. Fish & Wildlife Service and Kim Grveles of the Wisconsin Department of Natural Resources, the presence of three females was confirmed on Tuesday, and the presence of a fourth was confirmed yesterday, May 22. Two of the females have been observed carrying nesting material.
At least five males were present at the Adams County site at the end of last week. Two additional males arrived this week, bringing the total number of males to seven.
Incredibly, five of the males showed up this year wearing colored leg bands that they received in Adams County last year. A total of seven warblers were banded in Adams County in 2008. Most of the five now occupy territories close to the areas they occupied last year.
Trick and Grveles also announced that through yesterday a total of 223 cowbirds have been captured and removed from the site. USDA-Wildlife Services has had three cowbird traps in operation in Adams County since April 22. --C.H.
