Peregrines are capable of gliding and flapping speeds up to 60 mph, and of reaching speeds up to 200 mph in spectacular dives called stoops. This falcon flies with smooth, shallow, powerful wing beats, often soaring high with wings out flat and tail fanned when searching for prey, then diving and maneuvering at high speed to strike birds in midair. Like all other members of the falcon family, the Peregrine has a distinct notch in the upper mandible for cervical dislocation of its prey. Upper parts of the bird are a dark slate-gray and lightly barred underparts are a whitish color at the throat, shading to a buffy color with elongated spots on the chest, and more dark barring across the abdomen legs and feet of the adult are bright yellow. Important Bird Areas New Hampshire Bird Records NH eBird Peregrine Cam Peregrine Cam Since 1981, NH Audubon conservation biologists and a legion of dedicated volunteers have worked tirelessly to advance Peregrine Falcon population recovery in New Hampshire. The Peregrine Falcon has a black hood that extends down along the side of the head in a distinctive wide mustache mark. Plumage is similar between the sexes, but females are larger. 2011).A large, dark, powerful falcon with long, pointed wings and a long, narrow, tapered tail.
2012).Īlthough this species is increasing across many lowland areas of the UK, actions to reduce persecution are required to reverse recent declines in the uplands, where illegal persecution is believed to limit the population (see Causes of Change section).Įlsewhere, there are possible concerns about the risk of genetic introgression from escaped falcons following increases in the numbers of Peregrines and hybrid falcons in captivity ( Fleming et al. In northern England, breeding productivity on grouse moors has been 50% lower than at nests in other habitats, indicating that illegal persecution on land managed for Red Grouse shooting remains an important pressure on the population ( Amar et al. This could at least partly reflect the distributional changes: urban Peregrines have a higher number of fledglings per breeding attempt than rural birds, possibly linked at least in part to higher prey availability ( Kettel et al. Nest record information for the UK as a whole shows a significant rise in the number of fledglings per breeding attempt. Help the Phoenix name the falcons Thank you to the University community for submitting names in response to our call for names for the newly banded peregrine. When hunting, this remarkable bird will fly to great heights, then dive bomb its prey abruptly at sp. Illegal persecution continues to limit numbers in the uplands, and food supply may also be a limiting factor in some areas however persecution in lowland areas decreased during the 20th century, allowing numbers to benefit from the ban on organochlorine agrochemicals and from increased use of human structures as nest sites ( Wilson et al. The Peregrine falcon is not your average avian predator. 2018) and towards lowland regions and the coast Peregrine pairs in England have increased fivefold since 1981 and now, for the first time, outnumber those in Scotland ( Wilson et al. The overall increase between the 20 surveys masks a major distributional shift away from the uplands ( North East Scotland Raptor Study Group 2015, Wilson et al.
Populations and breeding performance have declined, however, in northwest Scotland and the Northern Isles ( Crick & Ratcliffe 1995). Illegal persecution continues to limit numbers in the uplands, and food supply may also be a limiting factor in some areas. The UK population size, distribution and breeding performance have all largely recovered from the poisonous effects of organochlorine pesticides in the 1950s and 1960s ( Newton 2013).
