Keeping up with kestrels

‘First-of-its-kind’ falcon tracking program took flight in Rappahannock

It is fast, fierce and flashy, with a plumage of oranges and slate blues for males; reddish-brown hues for females. Chances are you have seen one perched on a fence post or power line, surveying open fields for a meal. About the size of a mourning dove, it hovers like a helicopter before it swoops to catch a small rodent or insect.

American Kestrel Project team members Dr. Joe Kolowski, Caylen Wolfer, and Megan McDaniels (left to right) hold three male nestlings after measuring and attaching small radio transmitters to them. Two birds from each of the ten study nests were given lightweight radio transmitters to aid in tracking their movements and survival after they fledged.
