There is little contemporary research or literature
on the ecology and movements of vultures in
Malawi (see, Roxburgh & McDougall 2012,
Galanou 2016, Sievert et al. 2018).
Consequentially, the Convention on the
Conservation of Migratory Species Vulture Multi-
Species Action Plan, has identified Malawi as a
considerable knowledge gap for eastern and
southern African vulture populations (Botha et al.
2017). Historical information on the distribution of
vultures in Malawi is also sparse. However, four
species have been recorded as residents in Malawi,
namely: African White-backed Vulture Gyps
africanus, White-headed Vulture Trigonoceps
occipitalis, Hooded Vulture Necrosyrtes monachus
and Palm-nut Vulture Gypohierax angolensis
(Botha et al. 2017). Additionally, two species have
been identified as non-breeding visitors to Malawi,
the Lappet-faced Vulture Torgos tracheliotos and
the Cape Vulture Gyps coprotheres (Botha et al.
2017).
In the southern region of Malawi, vulture
monitoring in the form of opportunistic road counts
and camera trapping at carcasses, has been
underway in Liwonde National Park (14º50'31.5"S
35º20'59.9"E; Figure 1) since 2017. On the 6th of
November 2018 during monitoring, an adult
Rüppell’s Vulture Gyps rueppelli was spotted
feeding on an impala Aepyceros melampus among
African White-backed Vultures and a Marabou
Stork Leptoptilos crumeniferus (Figure 2). This
was the sole report or record of Rüppell’s Vultures
in Liwonde National Park that year. However, in
2019, a large bull African elephant Loxodonta
africana was found deceased through natural
causes in the central section of the park. Camera
trapping at this carcass took place for 52 days (5th
of May 11th of July) during which time Rüppell’s
Vultures were photographed. Over the course of
2019, a total of eight camera trap days yielded
photos of suspected Rüppell’s Vultures. An
additional report in 2019 totalled the number of
suspected Rüppell’s Vulture sightings in 2019 to
nine. Five of these sightings had high enough
quality images to allow species confirmation
(Figures 3,4,5,6,7), leaving four sightings
inconclusive.
Plumage of the individuals photographed
confirms a minimum of two separate Rüppell’s
Vultures, an adult and an immature, visiting the
park in 2019. However, given the number of
inconclusive sightings the authors cannot rule out
the presence of additional individuals. Initial
species identification was made based on plumage
while referencing Rodriguez & Elorriaga (2016).
Images were then sent to experts with extensive
experience working with the species for final
confirmation.

To the authors’ knowledge, these are the first
records of Rüppell’s Vultures in Malawi. Rüppell’s
Vultures occur throughout the Sahel region and the
East African savanna regions. A recent study of a
satellite tagged adult Rüppell’s Vultures revealed a
range size of 71,990 km2 over ten months (Virani
et al. 2012). Moreover, individuals have been
recorded on several occasions outside of the species
range in both the Iberian Peninsula and southern
Africa (Rodriguez & Elorriaga 2016, Botha et al.
2017, Botha & Román 2018). However, prior to our
report, there has been no definite evidence of the
species in Malawi. The recent sightings in Liwonde
National Park coupled with the recent record in
central Mozambique (Botha & Román 2018),
roughly 443 km southwest of Liwonde National
Park, suggests this species may be an uncommon
visitor to Malawi.
Considering the alarming decline in vulture
populations across Africa and the large multi-
country home ranges that many vulture species
inhabit, the development of cross-country
legislation is vital in the conservation of remaining
populations (Botha et al. 2017, Buechley et al.
2018). However, the large knowledge gaps that
remain must be addressed in order to create
informed conservation initiatives. Since the
initiation of Liwonde National Park’s vulture
monitoring in 2017, five species have been
identified across 241 sightings, including the before
mentioned Rüppell’s Vultures. Although Rüppell’s
Vultures may have occurred sporadically in Malawi
previously, no formal records could be located,
thereby demonstrating the importance of long-term
monitoring in expanding our knowledge of the
ranging behaviour of Africa’s vulture species.

... In the last 4 years, Liwonde National Park saw a recurrence of these four vulture species following an increase in law enforcement and the reintroduction of Cheetah (Acinonyx jubatus) and Lion (Panthera leo) (Sievert et al. 2018). Nevertheless, reporting rates for all vulture species in Malawi remain low (Roxburgh & McDougall 2012, Galanou 2016, Sievert et al. 2018, Sievert et al. 2020, especially regarding breeding sites for the four species listed as breeding residents: Whitebacked Vulture, Hooded Vulture, Lappet-faced Vulture and White-headed Vulture (Botha et al. 2017). Consequently, Malawi represents a considerable knowledge gap for southern and East African vulture populations in the Convention on the Conservation of Migratory Species' Vulture Multi-Species Action Plan (Botha et al. 2017). ...

Vultures comprise the most endangered avian foraging guild (obligate scavengers) and their loss from ecosystems can trigger trophic cascades, mesopredator release, and human rabies epidemics, indicating their keystone species status. Vultures’ extremely large home ranges, which often cross international borders of countries that have differing laws and capacity for wildlife conservation, makes conserving them challenging. However, satellite-tracking data can be used to identify habitat preferences and critical sites to target conservation actions. We tracked 16 Egyptian Vultures, Neophron percnopterus, in the Middle East and East Africa. We used dynamic Brownian bridge movement models to calculate home ranges and core-use areas, and we analyzed habitat use in a resource selection framework. Combined summer and winter ranges (99% utilization distributions) of all birds covered 209,800 and 274,300 km², respectively. However, the core-use areas (50% utilization distributions) in the summer and winter ranges, accounted for only 0.4–1.1% of this area (900 and 3100 km², respectively). These core-use areas are where the home ranges of multiple individuals overlapped and/or where individuals spent a lot of time, such as feeding and roosting sites, and are places where conservation actions could focus. Resource selection models predicted Egyptian Vulture occurrence throughout little-studied parts of the species’ range in the Middle East and East Africa, and revealed strong selection for proximity to highways, power distribution lines, and towns. While providing roosts (e.g. power pylons) and food (e.g. garbage dumps), anthropogenic features may also function as ecological traps by increasing exposure to electrocution and dietary toxins.

Asia and Africa have experienced recent catastrophic declines in populations of most species of vultures (Thiollay 2006, Ogada et al. 2011, Virani et al. 2011). While the declines in Asia have been linked to poisoning by the veterinary drug diclofenac (Oaks et al. 2004), the reasons for the declines across Africa remain poorly understood (Ogada et al. 2011), and are likely to have multiple causes, such as poisoning and a decline in food supply.

Vulture populations have been declining globally and regionally within Africa. Rüppell’s Vulture Gyps rueppellii is currently listed as ‘Near Threatened’ and numbers of the species, along with African White-backed Vultures G. africanus, have declined by 52% in and around the Mara-Serengeti ecosystem. A large breeding colony of Rüppell’s Vulture at Kwenia, southern Kenya, was monitored between 2002 and 2009. Around 150–200 adults were present on each visit, with up to 64 simultaneously active nests. The date of egg-laying differed considerably between years, with two discrete breeding attempts in some years. Nests were not positioned randomly across the cliff face and the number of active nests was related to rainfall in the previous year. The large ungulate migration of the Mara-Serengeti provides a vital foraging ground for the species. Conservation implications of the loss of vultures are discussed.
