The whistling kite (Haliastur sphenurus) is a medium-sized diurnal raptor found throughout Australia (including coastal islands), New Caledonia and much of New Guinea (excluding the central mountains and the northwest). Also called the whistling eagle or whistling hawk, it is named for its loud whistling call, which it often gives in flight. Some authorities put this species in the genus Milvus, despite marked differences in behaviour, voice and plumage between this species and other members of that genus.
It is one of three birds that intentionally sets or spreads fires to catch prey. The other two are the black kite and brown falcon. The whistling kite ranges in size from 50 to 60 cm (20 to 24 in), with a wingspan between 123 and 146 cm (4 ft 0 in and 4 ft 9 in). Weights range from 380 to 1,050 g (0.84 to 2.31 lb) an average of 600 to 750 g (1.32 to 1.65 lb) for males and 750 to 1,000 g (1.65 to 2.20 lb) for females. As with most raptors, females are larger and heavier than males; though there is considerable overlap between the sexes, females can be up to 21% larger and 42% heavier.
Southern birds are also larger than those found in the tropics. Male and female... Wikipedia →

Rare
Under 5% of wildlife watchers report a Whistling Kite sighting in Sydney on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 197th 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 Whistling Kite in Sydney on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Whistling Kite sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 cities where we can rate Whistling Kite sightings, Sydney ranks 4th at under 5%. The best odds are in Perth (Australia, about 10%), Brisbane (Australia, under 5%) and Melbourne (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Whistling Kite is recorded against all the birds logged in Sydney (39 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.
