The Peregrine Falcon is a Species of Special Concern in Ontario.

Why? What is being done about it?

Peregrine Falcons, although never common, were once widely distributed in Ontario. Their population declined drastically between the 1940s and the 1960s and they disappeared completely from Ontario in 1963. This was due to reproductive failure caused by exposure to the pesticide DDT. Concerns that the species could become extinct led to a breeding program in which 600 captive-raised young were released in Ontario from 1977 to 1996. Peregrine Falcons have adapted to life in cities, where food is plentiful and tall buildings provide high perches and nest sites. Volunteer Falcon Watches are established in many cities to keep an eye on chicks as they learn to fly above busy streets. Peregrine Falcons are also returning to formerly occupied wilderness areas in Ontario.

Under the Ontario Endangered Species Act, 2007 a special concern species is one that "lives in the wild in Ontario, is not endangered or threatened, but may become threatened or endangered because of a combination of biological characteristics and identified threats." The peregrines have made an amazing comeback from being an endangered species in Ontario, but they are still at risk. So our monitoring efforts continue.
