American Kestrel Study Update

29 May 2019

More than 70 citizen scientists, including students from the Salt Lake Center for Science Education, are monitoring 435 nest boxes along the Wasatch Front in Northern Utah. As of May 28, we have American Kestrels using 90+ boxes, 80 of these have eggs, with over half of these incubating complete clutches.

American Kestrel clutches range from one to six eggs, with five eggs being most common. Male and female Kestrels share duties during incubation, which lasts about 30 days. Over the past week, eggs have hatched in 21 boxes and we’ll begin nestling banding soon! Along with Kestrels, we also have Western Screech-owls using five nest boxes, and these currently have eggs or nestlings.
