Physical description Click here for a physical description Peregrine Falcons are relatively small raptors. They have a black head with yellow eye-ring, white half-collar, thinly barred grey-brown front (breast, belly and vent) and grey wings with dark-grey tips. The tail is barred grey. The bill is grey, with a yellow cere; the legs and feet are yellow. The underwing pattern is barred grey-brown, similar to the front of the body. Females are much larger than males. Juvenile Peregrine Falcons have a heavily streaked front, with an inconspicuous collar. The overall appearance is browner than an adult's. "Raptors" (or "birds of prey"), most prominently, but also some species of waders, show a pronounced "dimorphism", i.e. a difference between male and female birds - not just in the appearance of the plumage, but in other, important properties, such as size or strength. Here we explain why. Twitcher's tip Compared to Australian Hobbies the contrast between dark and light feathers (in both the facial pattern and general appearance) is more pronounced in Peregrine Falcons.

Taxonomy, classification See Peregrine Falcon at Wikipedia .

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Peregrine Falcon is available HERE . Peregrine Falcons are the species with the most wide-ranging distribution on Earth. For details on the ranges of the currently accepted 19 races, see e.g. a field guide or Wikipedia (also the more detailed range map). Basically, the only areas - apart from Antarctica, Iceland, most of Greenland and other far-northern islands - where they do NOT occur are the greater Amazon basin and Mato Grosso, the major deserts (Sahara, Gobi, central Arabia) and inland areas of central western Africa. Peregrine Falcons, race "macropus", are endemic to Australia. They inhabit the entire Australian continent, including Tasmania and other, especially rocky, coastal islands. They tend to stay away from human interference. In times of sufficient rainfall, and thereby sufficient prey, Peregrine Falcons can be found even in the most arid parts of the continent, i.e. the major sandy deserts of eastern WA, the Nullarbor and the Lake Eyre Basin. Note that there are also very rare reports of one of the far-northern races "tundrius" or "calidus" from Australia. Although primarily found in forest landscapes with escarpments or cliffs, Peregrine Falcons also hunt in more open country, both in the interior of the continent and on coastal islands. They have also been found by us in mountainous terrain of up to 1500 m altitude.

Sightings Click here for sighting information Race "macropus" Peregrine Falcons, race "macropus", are occasionally seen by us in the area of Narrabri, NSW, in northern inland NSW. The first sighting occurred in February 2008 at Eulah Creek, 20 km East of Narrabri, on the western fringes of the Nandewar Range, an area with sandstone escarpments suitable for nesting. Since 2013, Peregrine Falcons are seen semi-regularly by us in the area of Eulah Creek and Deriah Aboriginal Area. Two Peregrine Falcons, race "macropus", probably a pair, have been seen by us several times at the nearby Deriah Aboriginal Area, where we saw them twice in one day taking Bar-shouldered Doves. Peregrine Falcons have also repeatedly been found by us, and also by V. Collins, in Mt. Kaputar NP. B. Hensen reports spotting a pair of Peregrine Falcons, race "macropus", at Royal NP near Wattamolla, NSW, in June 2013. R. Plumtree spotted Peregrine Falcons, race "macropus", at Swan Reach Cliffs, East Gippsland, VIC, in May 2015 and again in July 2018. M. Windeyer reports spotting a Peregrine Falcon, race "macropus", at Gum Swamp, Forbes, NSW, in November 2015. J. Greaves reports spotting a Peregrine Falcon, race "macropus", at Dianella, Perth, WA, in July 2016. M. Eaton found a Peregrine Falcon, race "macropus", at the University of Queensland campus, St. Lucia, Brisbane, QLD, in August 2018. P. Brown spotted a Peregrine Falcon, race "macropus", at the Gooradalng Campground, Keep River NP, NT, in September 2020. In April 2022 M. Eaton observed a Peregrine Falcon, race "macropus", at Point Addis, VIC. In June 2023 M. Eaton found a pair of Peregrine Falcons, race "macropus", in Alice Springs, NT. Another pair was found nesting at Mt. Hypipamee, QLD, in August 2023.

PAIR

The photo shown here, of a pair, was used to determine the sexes of the two individuals (photos shown above from Alice Springs taken in June 2023). Note that the male, on the right, has brighter orange eye-rings, cere, bill and legs/feet than the female, indicating that this pair is breeding.

Food, Diet

Adults: Birds

Dependents: As adults

Water intake: None

All raptors are carnivores. Peregrine Falcons prey on smaller birds, up to the size of pigeons or ducks, which they take in flight.

During the first few weeks, raptors feed their chicks with pieces of meat. Later on in their development, the chicks learn to tear apart their parents' prey.
