Last weekend, Ed, Nick and I traveled to the Alpena area one last time to band Kestrel nestlings. With Arnie Pokorzynski as our guide, we were able to band 20 nestlings, bringing our total to 103 Kestrels. One interesting highlight was discovering 8 eggs in one nest box. American Kestrels usually lay 4-6 eggs, so this clutch was quite large. Although we do not know with certainty, we hypothesize that a female Kestrel may have laid some eggs that for some reason she was unable to return to, at which time another female Kestrel may have taken over the nest box and laid additional eggs. We also banded our 100th Kestrel!
Today, July 7, we visited 2 nest boxes in Emmet County which contained nestlings that had previously been too young to band. Both boxes contained 3 young each, which brought our season total to 109 American Kestrels banded. Only 1 of the 109 was an adult. Today will likely have been our last day of Kestrel banding this summer.
