VIII. Peregrine falcons
DDT was blamed for the decline in the peregrine falcon population.
The decline in the U.S. peregrine falcon population occurred long before the DDT years.

Peregrine falcons were deemed undesirable in the early 20th century. Dr. William Hornaday of the New York Zoological Society referred them as birds that "deserve death, but are so rare that we need not take them into account."
[Hornaday, WT. 1913. Our Vanishing Wild Life. New York Zoological Society, p. 226]
Oologists amassed great collections of falcon eggs.

The decline in falcons along the Hudson River was attributed to falconers, egg collectors, pigeon fanciers and disturbance by construction workers and others.

The 1950's and 1960's saw continuing harassment trapping brooding birds in their nests, removing fat samples for analysis and operating time-lapse cameras beside the nests for extended periods of time), predation and habitat destruction.

(Organochlorines in peregrines and merlins migrating through Wisconsin). Canadian Field-Naturalist 84:247-253]
Changes in climate (higher temperatures and decreasing precipitation) were blamed for the gradual disappearance of peregrines from the Rocky Mountains.
[Nelson, MW. 1969. Peregrine Falcon Populations, pp 61-72]
Falconers were blamed for decimating western populations.
[Herman, S. 1969. Peregrine Falcon Populations, University of Wisconsin Press]
During the 1960's, peregrines in northern Canada were "reproducing normally," even though they contained 30 times more DDT, DDD, and DDE than the midwestern peregrines that were allegedly extirpated by those chemicals.
[Enderson, JH and DD Berger. 1968. (Chlorinated hydrocarbons in peregrines from Northern Canada) Condor 70:170-178]
There was no decline in peregrine falcon pairs in Canada and Alaska between 1950 and 1967 despite the presence of DDT and DDE.
[Fyfe, RW. 1959. Peregrine Falcon Populations, pp 101-114; and Fyfe, RW. 1968. Auk 85: 383-384]
The peregrine with the very highest DDT residue (2,435 parts per million) was found feeding three healthy young.
[Enderson, JH. 1968. (Pesticide residues in Alaska and Yukon Territory) Auk 85: 683]
Shooting, egg collecting, falconry and disruption of nesting birds along the Yukon River and Colville River were reported to be the cause of the decline in peregrine falcon population.

The decline in British peregrine falcons ended by 1966, though DDT was as abundant as ever. The Federal Advisory Committee on Pesticides concluded "There is no close correlation between the declines in populations of predatory birds, particularly the peregrine falcon and the sparrow hawk, and the use of DDT."
[Wilson report. 1969. Review of Organochlorine pesticides in Britain. Report by the Advisory Committee on toxic chemicals. Department of Education and Science]
During 1940-1945, the British Air Ministry shot about 600 peregrines (half the pre-1939 level) to protect carrier pigeons.
Peregrine falcon and sparrow hawk egg shells thinned in Britain prior to the use of DDT.
