In late 2005, it was discovered that a pair of Peregrine falcons had taken up residence on the Cathedral Tower.

Its relationship to other falcons is not clear ; the issue is complicated by widespread hybridization confounding mtDNA sequence analyses ; for example a genetic lineage of the Saker Falcon ( F. cherrug ) is known which originated from a male Saker producing fertile young with a female Peregrine ancestor, and the descendants further breeding with Sakers.

Up to 80 % of the diet of Peregrine Falcons in several cities that have breeding falcons is compromised by feral pigeons.

Peregrine falcons have recently returned to the Monument to breed also, but in far fewer numbers.

Studies by the Swedish Society for Nature Conservation found for the first time very high levels of higher brominated PBDEs ( BDE-209 ) in eggs of Peregrine falcons.

The site is well known for its resident breeding pair of peregrine falcons, which are protected during the breeding season by Operation Peregrine, providing security for the birds and a chance for the public to view the birds through scopes and CCTV.

Peregrine falcons and ravens nest near the waterfall and derelict military structures, probably pump-houses supplying water for the Blue Streak rocket site at RAF Spadeadam, can be seen just upstream.

Quarries on the Bristol side of the gorge are now popular with climbers and are a habitat for Peregrine falcons and other wildlife.

Foxes and once-endangered Peregrine falcons, which frequent large outdoor structures such as the EOT gantry cranes at the ore docks, thrive on the island and offshore at the bottom of the Detroit River is a man-made bed of coal cinders which serves as a rare spawning site for Lake Sturgeon, a threatened species.

Peregrine falcons are sometimes sighted on the top of this building.

Birds of prey in the park include snowy owls, rough-legged hawks, gyrfalcons, and Peregrine falcons, who feed on the lemmings.

Peregrine falcons nest in the high bluffs overlooking the river, while the rolling hills that make up the preserve are home to an abundant array of wildlife.

The four houses are named after four falcons: Kestrel, Merlin, Peregrine, and Saker.

In one instance, a Golden Eagle flying in towards a Peregrine Falcon ( Falco peregrinus ) nest was struck and killed by a swooping parent falcon, a reversal of fortune for the falcon given that the much larger eagle is usually dominant over ( and a potential predator of ) them.

The Peregrine Falcon ( Falco peregrinus ), also known as the Peregrine, and historically as the Duck Hawk in North America, is a widespread bird of prey in the family Falconidae.

The area supports substantial populations of upland birds including raptors, such as the Hen Harrier ( Circus cyaneus ), Merlin ( Falco columbarius ), and Peregrine ( Falco peregrinus ) ( about 14 – 18 breeding pairs of each species, 1 %– 2 % of the total British population ), and for this reason it is a Special Protection Area classified in accordance with the European Union's Birds Directive.

Predators of adults include the Peregrine Falcon ( Falco peregrinus ), Snowy Owl ( Bubo scandiacus ), Bald Eagle ( Haliaeetus leucocephalus ), Golden Eagle ( Aquila chrysaetos ), Red-tailed Hawk ( Buteo jamaicensis ), Great Horned Owl ( Bubo virginianus ), Eurasian Eagle Owl ( Bubo bubo ), and Cooper's Hawk ( Accipiter cooperii ).

However, this is implausible for reasons of biogeography, and more recently, Falco mexicanus is considered an early aridland offshoot of the Peregrine Falcon lineage, much as the hierofalcons represent a later divergence that similarly adapted to arid habitat.

The Peregrine Fund began reintroducing captive-bred Northern Aplomado Falcons ( Falco femoralis septentrionalis ) to the refuge in 1985, which had been nearly extirpated from the Southwestern United States ; today, it is home to 40 pairs.
