Peregrine Falcon, Mississippi Valley, Bellevue State Park, Iowa
I read that the 17 nest sites of Peregrin Falcons were observed in Iowa and 36 young falcons hatched and were raised last year. As many birds of prey the peregrine was affected by DDT and other biocides in the 1950s and remained an endangered species in Iowa until 2010. The Peregrin Falcon is the fastest bird on record and may reach speeds of 320 km/h, about 200 miles per hour, as it drops towards its prey.
One of the nest boxes is attached to a rock wall in the Mississippi Valley, just south of Bellevue, IA and next to highway 52. Any time I drive by on my way to the Green Island Wetlands I raise my head and have a look if I see any activities at this time of the year. A couple days ago both adult falcons were present, one in the nest box and the other one higher above in a tree. A good reason to stop and take the camera out. Sure, this is not a perfect wildlife photo and I hope to have another chance sometime in April.
