Breeding information

Breeding season: Jul - Dec Eggs: 2 - 3 Incubation period: ca. 35 days Fledging age: ca. 40 days

The breeding season for Black Kites depends on geographical latitude and weather conditions. In the tropical north, they can breed any time of the year.

Twitcher's tip

Note that, by the time they fledge (i.e., leave their nest), the young of all species of raptors - apart from the tail and wing feathers (which are still growing) - are already full adult-size.

Nest

"bungobittah", "malunna" = nest [Aboriginal]

Type: Basket Material: Sticks; leaves, grass, bark, wool lining Height above ground: 10 - 20(?) m

Eggs

"boyanga", "booyanga", "derinya", "dirandil", "koomura", "ngampu", "nooluk", "pateena" = Egg; "dirundirri" = eggs [Aboriginal]; "gawu" = eggs [gamilaraay]

Size: 52 x 42 mm Colour: Creamy, with light- to mid-brown speckles Shape: Tapered oval

Behaviour

Social behaviour: Communal Mobility: Nomadic/dispersive Elementary unit: Flock

Black Kites are the first bird species to re-enter open grassland after a fire, looking for prey that has been killed by the fire. In more vegetated bushland, this role falls to Brown Falcons.

Black Kites are the only species of raptor known to us that will congregate in large numbers. In the Outback, up to 50 were spotted by us together in one flock. Near the rubbish tip in Darwin, NT, we found a flock of about 1000 Black Kites.

Food, Diet

Adults: Carrion, small mammals, birds Dependents: As adults Water intake: None

All raptors are carnivores. Black Kites mainly feed on carrion. They are often found around rubbish tips. Black Kites have a preference for "deep-fried" prey; they specialize in cleaning up after bushfires.

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.

Although blown to smithereens, this roadkill still holds some attraction for a Black Kite (photo courtesy of M. Mearns)
