Neophron percnopterus
SUBFAMILY
Accipitrinae
TAXONOMY
Vultur perenopterus [sic] Linnaeus, 1758, Egypt. Two subspecies.
OTHER COMMON NAMES
English: Scavenger vulture; French: Vautour percnoptиre; German:
Schmutzgeier; Spanish: Alimoche Comъn.
PHYSICAL CHARACTERISTICS
22.8–27.6 in (58–70 cm); 3.5–4.9 lb (1.6–2.2 kg). Distinctive
contrasting coloration between white head and body and black
flight feathers.
DISTRIBUTION
N.p. percnopterus: Europe to central Asia and northwest India,
south to Tanzania, Angola, and Namibia; also Canary and Cape
Verde Islands and Socotra. N.p. ginginianus: India and Nepal.
HABITAT
Frequents extensive open country of dry, arid regions: steppe,
scrub, desert, pastures, and cereal crops. Also in flat mountainous
areas usually at low to moderate altitudes, cities and towns
(especially Africa and India). Nests in rocky areas.
BEHAVIOR
Usually solitary or in pairs but a hundred or more may congregate
where food is abundant and at roosts on cliffs, trees or on
buildings. In north of range migrate to Africa just south of Sahara
and north of the equator. In India, Arabia, sub-Saharan
Africa, Balearic and Canary Islands apparently sedentary or
make local movements.
FEEDING ECOLOGY AND DIET
Opportunistic feeder, dependent on rubbish dumps and carcass
disposal sites; carrion and refuse is main food. Less often,
catches live prey, usually sick or otherwise vulnerable. Also insects,
crustaceans lifted from the water and birds’ eggs; large
eggs broken by throwing a stone.
REPRODUCTIVE BIOLOGY
Usually, breeds as solitary pair but occasionally two nests in close
proximity. Monogamous. Builds a substantial, untidy nest of sticks
lined with wool, rags and hair in a cleft, cave or narrow ledge at
height on a cliff, often overhung; also on ruins, date palms and
other trees where no cliffs. Typically, lays two eggs in March–
May (earlier in some areas); incubation 42 days; fledges at about
11 weeks. Unlike most raptors, regurgitates food for chicks.
CONSERVATION STATUS
Not threatened. Population has undergone a general decline
but may now be stable. Main European population is now
Spain; main population is Ethiopia. Fewer carcasses, reductions
in small prey species, poisoning and persecution all thought to
be factors in decline.
SIGNIFICANCE TO HUMANS
Its image was carved into Egyptian monuments but apparently
the species was never worshipped, as was the more powerful
Eurasian griffon (Gyps fulvus).
