A Home for Kestrels

Laudato Si’ Project has ambitious goals for 2018 to help this species recover.

A Male American Kestrel

Few birds of prey in WI can rival the beauty of the American Kestrel. At roughly the size of a Mourning Dove, it is North America’s smallest falcon. Unfortunately, it has declined nearly 50% over much of its range since the 1960’s.  Reasons for the decline are varied

but include continued clearing of land and felling of the standing dead trees these birds depend on for their nest sites. The American Kestrel is also losing prey sources and nesting cavities to so-called “clean” farming practices, which remove hedgerows, trees, and brush. An additional threat is exposure to pesticides and other pollutants, which can reduce clutch sizes and hatching success. For kestrels in North America, a larger problem with pesticides is that they destroy the insects, spiders, and other prey on which the birds depend.

Laudato Si’ Project is responding to kestrel decline the same way we responded to blue bird decline- the installation of nesting boxes (See past blog post Bluebird Nest Boxes). LSP has already begun the construction and hanging of Kestrel nest boxes. Kestrel’s prefer open habitat where they hunt for rodents, grasshoppers, and other insects. This presents great opportunities for LSP to work with landowner’s in Southeastern Wisconsin installing nest boxes and increasing nest success. Nest boxes can be placed 10-25 feet up on non-utility telephone poles, lone trees or barns. Farm’s, pastures, and preserves managed by our partners provide countless opportunities to help a species in need. These nest boxes also create monitoring and educational opportunities for both students and adults.

Cool Kestrel Facts from the Cornell Lab of Ornithology

  • It can be tough being one of the smallest birds of prey. Despite their fierce lifestyle, American Kestrels end up as prey for larger birds such as Northern Goshawks, Red-tailed Hawks, Barn Owls, American Crows, and Sharp-shinned and Cooper’s Hawks.
  • Unlike humans, birds can see ultraviolet light. This enables kestrels to make out the trails of urine that voles, a common prey mammal, leave as they run along the ground. Like neon diner signs, these bright paths may highlight the way to a meal—as has been observed in the Eurasian Kestrel, a close relative.
  • Kestrels hide surplus kills in grass clumps, tree roots, bushes, fence posts, tree limbs, and cavities, to save the food for lean times or to hide it from thieves. 
  • The oldest American Kestrel was a male and at least 14 years, 8 months old when he was found in Utah in 2001. He had been banded in the same state in 1987.
