Peregrines: Bridge to Bluff – MB&G Gets Back to Nature

MB&G wildlife biologists have supported the peregrine falcon conservation effort for nearly two decades

Peregrine4 2018For over 17 years, MB&G wildlife biologists have surveyed peregrine falcons nesting and habitat near and on Portland’s bridges. In April 2018, MB&G’s team of scientists had the rare opportunity to survey these fascinating birds on the face of a cliff located in Clackamas County, Oregon. 

Peregrine falcons represent a success story of species recovery. Peregrine populations were in steep decline during the mid-20th century, largely due to the extensive use of the insecticide DDT. In 1973, peregrine falcons were listed as Endangered under the Federal Endangered Species Act and later listed as Threatened under the Oregon Endangered Species Act.  A regional recovery program was initiated to assist cooperating agencies in the site-specific management of the few remaining peregrine falcons. The Audubon Society of Portland has recounted that by 1975 there were only two nesting pairs of peregrine falcons in California and none in Oregon or Washington.

Peregrine3 2018Because of a long recovery effort, peregrine falcons are becoming a more common occurrence in the Pacific Northwest. They are reestablishing their natural nesting sites and also inhabit Portland’s bridges. Peregrines were de-listed from the Federal Endangered Species List in 1999 and the Oregon Endangered Species List in 2007. Today there are more than 160 nesting sites in Oregon.

Peregrine 2018Although peregrine is no longer a listed species, ongoing monitoring activities help to track their recovery and can assist in early detection of potential environmental conditions that might threaten the current population.

Peregrine2 2018MB&G wildlife biologists have supported the peregrine falcon conservation effort for nearly two decades and emerged with unsurpassed expertise in surveying and monitoring for this species. The MB&G wildlife team is proud to contribute their skills, passion, and collected data for research, conservation, and outreach to assist in the recovery of the peregrine falcon.
