Eighteen birds captured on the first net round made Mattie and I think that we may be in for a good morning. Well . . . the 2nd net round yielded only 2 birds and the 3rd only one. But, we ended up the day with 32 new birds and 8 recaptures of 7 different species. Of the 32 new birds banded 31 of them were Yellow-rumped Warblers. Yellow-rumps will be the majority for the remainder of the season.
Last year I did a post on how we age and sex Yellow-rumped Warblers. Rather than reinventing the wheel and replicating that post I will just provide a link to it. It shows a very detailed description on molt limits used in ageing and the plumage characteristics that we look at in order to determine the sex of individuals.
