The square-tailed kite (Lophoictinia isura) is a medium-sized bird of prey native to Australia. It is in the family Accipitridae, which also includes many other diurnal raptors such as kites, eagles and harriers. German naturalist Johann Jakob Kaup described the square-tailed kite in 1847.
The square-tailed kite is monomorphic with no recorded geographic variations. As an adult the square-tailed kite is a medium-sized raptor, with the following features: Length: 50–56 cm (tail is about half the length of bird)
Wingspan: 130–145 cm Weight: Male-501g, Female-650g As an adult, the squared-tailed kite has a white face, with pale eyes and black streaks across the crown. The breast is also heavily streaked. The ventral surface of the wings has a rufous-brown lining, a dark carpal crescent, and a boldly barred finger. There is also a pale white patch on the ventral surface of the wings, at the base of the primary feathers; the saddle, rump and central upper tail-coverts are blackish, while the upper tail-coverts are grey-brown and fade into a small pale patch above the tail. The tail itself is square with dark sub-terminal band. Square... Wikipedia →

Rare
Under 5% of wildlife watchers report a Square-tailed Kite sighting in Sydney on a given day, based on 159 verified sightings from GBIF citizen-science data. It is the 156th most-seen of the 243 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Square-tailed Kite in Sydney on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Square-tailed Kite sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate Square-tailed Kite sightings, Sydney ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Brisbane (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Square-tailed Kite is recorded against all the birds logged in Sydney (159 verified sightings), 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.
