What is in this article?
When most people think of raptors, they often picture powerful hunters such as eagles, hawks, or falcons, birds known for chasing and capturing live prey with speed and precision. Vultures, however, are often viewed differently. They are more commonly seen circling high in the sky or gathered around carcasses, feeding on animals that have already died. Because of this scavenging behaviour, many people wonder whether vultures truly belong to the same group as other birds of prey.
Are Vultures Raptors?
In reality, vultures share many of the key characteristics that define raptors. Like other birds of prey, they possess strong hooked beaks designed for tearing flesh, powerful feet, and exceptional eyesight that allows them to detect food from great distances. These features place Vultures firmly within the broader group of birds known as raptors. So yes, Vultures are considered to be Raptors even though they don't hunt for their food but rather prefer to feed on carcasses or dead animals.
What makes vultures unique is not that they are different from raptors, but that they have evolved a specialized role within this group as nature’s primary scavengers.
Vultures are generally divided into two main groups based on where they occur in the world: Old World vultures and New World vultures. Old World vultures are found across Africa, Europe, and Asia, while New World vultures occur in North and South America. Although both groups share similar feeding habits as scavengers and play the same ecological role, they are not closely related. Instead, they evolved similar features independently, a process known as convergent evolution.
Old World vultures, such as the Hooded Vulture, rely mainly on their excellent eyesight to locate carcasses from high in the sky. In contrast, some New World vultures, like the Turkey Vulture, have a well-developed sense of smell that helps them detect carcasses hidden beneath forest cover. Despite these differences, both groups play the same important role in nature by removing dead animals and helping to keep ecosystems clean.
Meet the Hooded Vulture
Common name: Hooded Vulture
Scientific name: Necrosyrtes monachus
Among Africa’s vultures, the Hooded Vulture is one of the most recognizable species. It is widely distributed across sub-Saharan Africa and is often found near towns, villages, markets, and slaughter areas where food is available. Despite this wide distribution and its close association with human settlements, the species has experienced rapid population declines in recent decades.
Threats such as poisoning, habitat changes, and persecution have led to the Hooded Vulture being classified as Endangered. Understanding where this species occurs and how its distribution is changing is therefore essential for guiding conservation actions and protecting one of Africa’s most important natural scavengers.
Habitat Preference of the Hooded Vulture
The Hooded Vulture is highly adaptable and can live in a wide range of habitats. It is commonly found in open areas such as savannas, grasslands, and forest edges, where trees are available for roosting and nesting.
What makes this species unique is its strong link to humans. It is often seen in towns, markets, dumpsites, and near slaughter areas, where food is easy to find. In many parts of West Africa, including Ghana, it prefers urban and settlement areas because of the constant supply of waste and carrion.
For nesting, Hooded Vultures rely on tall trees, usually in open or lightly wooded areas, and sometimes near water sources.
Distribution of the Hooded Vulture around the world and in Ghana
Based on the map created from eBird data, the Hooded Vulture is most abundant across West Africa through to East Africa, where records are widely spread and consistent. Its presence continues into parts of Southern Africa, but the pattern becomes less even.
There are very few records in South Africa, suggesting the species is not common there. Instead, observations in the southern region are more concentrated in countries like Botswana and Mozambique, where it appears more regularly.
The circle represents Ghana, and you can clearly see that the Hooded Vulture is still found there, even though its numbers are declining. This shows that while the species has not disappeared, its population is under pressure, and continued monitoring and conservation efforts are needed to prevent further decline.

Seasonal Presence in Ghana
The graph shows that records of the Hooded Vulture in Ghana peak between November and March, followed by a noticeable decline after March. This pattern can be explained by a combination of seasonal ecology, breeding behaviour, and food availability.
First, it is important to note that Hooded Vultures are largely resident and non-migratory in West Africa, meaning they are present year-round rather than seasonally migrating in and out of the country. Therefore, the pattern observed in the data reflects changes in detectability and activity, not true absence.
Dry season (November–March): Peak records
The period from November to March corresponds largely to the dry season in Ghana, and this aligns with the highest number of observations. This can be explained by several factors:
🔹Increased foraging visibility
During the dry season:
Vegetation cover is reduced
Landscapes are more open
This makes vultures easier to detect and record, especially in savanna and urban environments.
🔹Food concentration
Hooded Vultures are highly opportunistic scavengers, feeding on carcasses, waste, and abattoir remains, often around human settlements. In the dry season:
Natural food sources become more limited
Carcasses may persist longer due to lower decomposition rates
This leads to aggregation of vultures at predictable feeding sites, increasing observation rates.
🔹 Breeding season influence
Breeding in many regions of Africa, including West Africa, is closely tied to the dry season.
During this time:
Adults are more localized around nesting sites
They make repeated foraging trips within a fixed range
This increases their visibility and consistency in specific areas, leading to more frequent records.
Wet season (after March): Decline in records
After March, Ghana transitions into the rainy season, and this corresponds with the observed decline in records.
🔹 Increased vegetation cover
Dense vegetation reduces visibility
Birds are harder to detect even if present
This leads to lower reporting rates, not necessarily fewer birds.
🔹 Dispersed food resources
During the rainy season:
There is a greater availability of natural food sources
Carcasses decompose faster
Insect availability increases (e.g., termite emergences)
Hooded Vultures may:
Feed more widely and opportunistically
Spread out across the landscape
This reduces clustering and makes them less conspicuous.
🔹 Post-breeding dispersal
After breeding:
Adults are no longer tied to nests
Juveniles begin to move and disperse
This leads to less predictable spatial patterns, reducing repeated observations in the same locations.
