The brown falcon (Falco berigora) is a relatively large falcon native to Australia and New Guinea. A number of plumage morphs occur, with the primary distinction being between the pale morph and the dark morph. Both morphs usually have dark brown upper parts and wing coverts. Dark morph birds have predominantly dark under parts, although some light streaking is common. Pale morph birds have white underparts that are varyingly streaked with brown, sometimes heavily so. Pale individuals may also have prominently white under tail coverts and these may be diagnostic. A distinctive aspect of their behaviour is shown in the breeding season when brown falcons make a loud, high pitched, cackle call (like a laying hen) and screeching while in flight.
The species name berigora has Aboriginal origins. Adults are usually 40 to 50 cm (16 to 20 in) long. They are found in light and dark forms and a variety of intermediates. Animals typically have red-brown heads with narrow black streaks with a light crown and off-white chin. Wings are a spotted red-brown with dark brown quills. Beaks are light blue/grey; eyes are brown. The falcons make a loud cackle call uttered frequently.... Wikipedia →

Rare
Under 5% of wildlife watchers report a Brown Falcon sighting in Nitmiluk National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 96th most-seen of the 103 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Brown Falcon in Nitmiluk National Park on a given day, against under 5% in October to August, the lowest months. That is one of Nitmiluk National Park's driest months, with about 10 mm of rain against 270 mm in January.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Brown Falcon sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
12th of 18
Of the 18 parks where we can rate Brown Falcon sightings, Nitmiluk National Park ranks 12th at under 5%. The best odds are in Uluru-Kata Tjuta National Park (Australia, about 30%), Flinders Ranges National Park (Australia, about 20%) and Kakadu National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Brown Falcon is recorded against all the birds logged in Nitmiluk National Park (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
