Animals in Summer: Ferruginous Hawk

Animals in Summer: Ferruginous Hawk

posted in: Native animals | 0

Birds of prey are scientifically classified as indicator species, meaning that the health of the entire ecosystem can be affected by their loss. Healthy ecosystems have birds of prey, but ecosystems under pressure rapidly lose these majestic creatures. Hawks are critical because they keep small mammal populations under control and are a top predator in Washington’s prairie habitat.  

The ferruginous hawk is a threatened species, native to the eastern part of our state. This hawk is particularly large, with wingspans reaching up to 60 inches (5 feet) across! Within its more eastern range, the hawk was noted for using bison bones in the construction of its nests. Today, this hawk builds nest similar to those of an eagle – large constructions of twigs, which a bonded, mating pair will return to year after year.  

The major threat to the ferruginous hawk is habitat loss from human encroachment. As prairie is converted into agricultural land, the ferruginous hawk loses its hunting grounds and nesting sites.
