The Black Kite is a medium-sized bird of prey that glides and spends extensive time in the air. Its long-angled wings and long forked tail give it a “gangly” appearance. Plumage is a relatively uniform dark brown. The underside of the wing has pale panels on the inner primary feathers and the outer “finger” primaries are dark. Many individuals have grey heads and dark eye rings. Juvenile Black Kites are a bit paler and have spotted backs and heads. Black Kites are omnivorous and frequent garbage dumps and landfills. They also catch flying insects, and thus spend much of their time airborne.
A common winter visitor and passage migrant. No nesting has been observed during the past two decades. A single pair was seen in courtship display on the Mt. Hermon slopes in the summers of 1998-2000 (Ohad Hatsofe, pers. comm.). Until the mid-20th century, tens of pairs nested in Northern and Central Israel, south to Mikve Yisrael. The breeding population, like the wintering population, was decimated by pesticide poisoning during the 1950s. Nesting resumed in the 1980s, and a number of pairs (five at the most) nested in the northern Hula Valley and the Mt. Hermon slopes (Paz 1986, Shirihai 1996). The nesting sites were abandoned in the 1990s (Ohad Hatsofe, Efraim Ezov, pers. comm.), once again probably due to secondary poisoning (Mayrose and Alon 2001).
The Black Kite probably became extinct as a breeder due to secondary poisoning from agricultural pesticides. Kites are particularly susceptible to poisoning because they are omnivorous and feed on carrion, making them vulnerable to both insecticides and rodenticides.
The Black Kite has received low priority for active restoration management (Hatsofe & Mayrose 2015) for the following reasons:
Some of its extinction factors are still present.
The global population is increasing
The probability that the species will naturally return to breed in Israel is estimated to be high, because the species is expanding in Eastern Europe and the number of migrant and wintering Black Kites in Israel is continuously rising.

Occupancy 1990-2020
The map shows differences in the species breeding distribution between the 1980's breeding map and the current weighted breeding evaluation. Negative value - species previously bred in the grid and is not presently breeding; positive value - species has not previously bred in the grid and is currently breeding.

Change in Relative Abundance 1990-2020
The map shows the changes in the relative abundance of a species in each of the distribution grids between the breeding map of the 1980s and the weighted current breeding evaluation. Negative values - decline in abundance; positive values - increase in abundance; zero - no change in abundance.
