ABSTRACT
This study assessed the nesting patterns of lap-
pet faced vulture in Lochinvar National Park, on
the Kafue flats, Zambia. Road drives and foot
patrols were used to identify and take GPS co-
ordinates of lappet faced vulture nests. The
main objectives of the study were: 1) to obtain
basic breeding information of lappet-faced vul-
ture in Lochinvar National Park and the Kafue
Flats in general, 2) to determine size of the
breeding population in the National Park, 3) to
document distribution of the nesting sites, 4)
to facilitate development of a monitoring pro-
gramme that would secure the nesting sites
from human disturbance, and 5) to determine
availability of suitable nesting sites and major
threats that may interfere with breeding. Tree
species on which nests were found were identi-
fied and height of nest above ground was esti-
mated. A total of 22 nests were recorded with 5
(23%) being lappet faced vulture nests on seven
species of trees. The mean height for nest placa-
menet was 10 m above ground. Host tree phy-
siognomy, size and height were important cha-
racteristics in nest placement. Large trees of
10 m and above are critical in facilitating nest
placement and must be protected in identified
breeding sites.

1. INTRODUCTION
Vultures are very special type of raptors. They locate
carcasses by scanning the ground while soaring high in
the air [1]. While they soar, they also observe each other,
so that when one identifies a carcass and descends, oth-
ers would follow. They are large and robustly built (Fig-
ure 1), and due to their large size, they mainly depend on
soaring flight and often congregate in large numbers at a
carcass. After identifying potential food, they usually
perch on nearby trees to be sure that the animal is dead,
and this is why it is important to have large trees with
branches large enough to support their weight. From the
perch, one or few brave birds will take the lead to the
carcass and soon others will follow. Like other raptors,
vultures are on top of the food chain and as such play an
important role in the functioning of ecosystems. Re-
garding its size, the lappet-faced vulture is the largest of
the three dark vulture species, the other two being
hooded (Necrosyrtes monachus) and white headed (Aegy-
pius occipitalis) (Figure 1). It also ranks as the longest
and largest winged vulture in its range behind the close-
ly related cinereous vulture (Aegypius monachus) [1],
although some co-occurring Gyps vultures tend to be
heavier on average, especially the cape vulture (Gyps
coprotheres) and Eurasian griffon (Gyps fulvus). Its hea-
vy yellowish hooked bill and bare red head with its
consipicuous skin folds are a major diagnostic feature
among other raptors (Figure 2).
The Lappet-faced vulture or Nubian vulture (Torgos
tracheliotos) is mostly African Old World vulture be-
longing to order Accipitriformes, which also includes
eagles, kites, buzzards and hawks, but its size and shape
of beak are unmistakenly larger than other raptors (Fig-
ure 2). It is the only member of the genus Torgos. It was
formerly considered monotypical, but has now been
separated into two subspecies: 1) the nominate race
which is found almost throughout Africa, and 2) sub-
