Bearded Vulture (Lammergeyer) on Mount Kilimanjaro

What Is the Bearded Vulture (Lammergeyer)?

The Bearded Vulture (Gypaetus barbatus, genus Gypaetus) — known as the Lammergeier — is a huge mountain-dwelling bird of prey recognised by its long, wedge-shaped tail, narrow wings, dark facial mask and russet-orange underparts. It feeds mainly on bones and bone marrow from carcasses.

How to Identify It

A huge vulture, approximately 100–115 cm in length, with a wingspan roughly two to three times its body length. Adults have a pale cream, buff or orange-toned head and underparts contrasting with dark grey to slate upperparts and long dark flight feathers. A dark facial mask and short bristly tuft below the bill — the 'beard' — give the species its name. The eye is pale, often with a reddish eye-ring. The long, narrow wings and exceptionally long wedge-shaped tail create a distinctive silhouette in soaring flight. The orange-rust underparts stain is acquired through bathing in iron-rich soil and water, not inherent. Juveniles are much darker and gradually gain adult plumage over several years.

Similar Species

• White-backed Vulture — much paler, very broad wings, gathers at carcasses.
• Rüppell's Vulture — larger, broader wings, often feeds in large groups.
• Lappet-faced Vulture — larger, massive hooked bill, bare red head.

Natural Habitat

High mountains, rugged escarpments, rocky ridges, deep gorges, cliffs and adjoining open grasslands. It favours high cliffs and craggy terrain where rising air allows prolonged soaring while scanning for carrion.

Where to Find It

The Bearded Vulture is included in the current Avibase Kilimanjaro National Park bird checklist. This is park-level checklist evidence; it does not establish sightings on any named climbing route, camp, viewpoint or altitude band. No trekking route is promoted as a confirmed viewing location, and the current local population size is not independently established.

Diet and Feeding Behaviour

Bones and bone marrow from carcasses are its speciality — it may carry large bones into the air and drop them onto rocks to break them. It also consumes meat and other carrion, particularly when feeding chicks. The bone-based diet makes it a specialised and important scavenger.

Behaviour and Daily Activity

A powerful soarer using mountain updrafts and thermals to travel ridges and valleys with minimal flapping. It searches wide areas for carcasses, following mountain slopes and open landscapes. Generally seen alone or in pairs rather than in large feeding gatherings. Its long wings and wedge-shaped tail create a distinctive flight silhouette, often observed from great distances.

Calls and Communication

Generally quiet in flight; a gruff, croaking or wailing call, occasionally given around the nest or in aerial displays. It is not a musical songbird.

Breeding and Nesting

Nests in rugged cliff environments — a substantial stick nest in a sheltered cave, pothole or protected ledge, lined with softer materials such as wool and fur. Pairs may maintain more than one nest site and use different ones in different seasons. Although two eggs may be laid, a pair generally raises only one chick successfully. No Kilimanjaro breeding calendar is published here.

Distribution

Discontinuous African distribution concentrated in highland regions — Ethiopia and parts of East Africa, among other separated mountain ranges. Tanzania lies within its recognised global range. It is not documented as a confirmed route species on Kilimanjaro.

Conservation Status

Near Threatened (NT) globally in the IUCN assessment used for this profile. The same assessment reports a decreasing global population trend — a global figure, not a measured Kilimanjaro population trend. Threats include poisoning, disturbance near nests, collisions with infrastructure and reductions in food availability.

Best Time to Observe

Watch for large soaring silhouettes near cliffs and crags on warm days when thermals lift birds; scan the high sky with binoculars; record date, location, elevation and identification features of any sighting.

Photography Tips

Photograph from a respectful distance with a long lens; never approach nesting cliffs or disturb nest sites; never bait or call the bird.

Ecological Importance

An important scavenger that recycles animal remains and returns nutrients to the ecosystem. An elusive but specialised component of the highland bird community.

Why It Matters in Tanzania

Responsible Birdwatching

Keep respectful distance, never disturb cliff faces or nests, never approach a raptor for a photograph, and report credible sightings to your guide or park authorities.
