What is the African Snake Killing Bird?
The African snake killing bird is the Secretarybird (Sagittarius serpentarius), a large, terrestrial raptor renowned for its unique appearance and its ability to hunt and kill snakes effectively with its powerful legs and sharp talons. This striking bird is a vital part of the African ecosystem.
Introduction to the Secretarybird
The Secretarybird is a truly remarkable avian species found across sub-Saharan Africa. Unlike most raptors, which are primarily aerial hunters, the Secretarybird spends much of its time on the ground, stalking through grasslands and savannas in search of prey. Its long legs and elegant crest feathers give it a distinctive appearance, setting it apart from other birds of prey. But what is the African snake killing bird’s secret to success?
Physical Characteristics
The Secretarybird boasts a unique combination of features:
- Height: Standing up to 4 feet tall, it’s an imposing figure on the African plains.
- Legs: Its long, powerful legs are its primary weapon, allowing it to strike and stomp on prey with tremendous force.
- Plumage: Predominantly gray with black flight feathers and thighs, the Secretarybird has a distinctive, almost pen-like crest on the back of its head, resembling quill pens stuck behind a secretary’s ear – hence its name.
- Face: A bare, reddish-orange facial skin patch surrounds its eyes.
- Talons: While not as sharply curved as those of other raptors, its talons are still effective for grasping and holding prey.
Hunting Strategy and Diet
What is the African snake killing bird’s primary hunting method? It relies on a combination of keen eyesight and powerful legs. Secretarybirds walk through tall grasses, scanning for prey. When a snake, rodent, insect, or other small animal is spotted, the bird will rapidly approach and deliver powerful kicks with its legs. These kicks often stun or kill the prey. They are especially adept at dispatching snakes, using their legs to stomp on the reptile’s head or body.
Their diet consists mainly of:
- Snakes (including venomous species)
- Lizards
- Rodents
- Insects
- Small birds
- Eggs
Conservation Status and Threats
The Secretarybird is currently listed as Vulnerable by the International Union for Conservation of Nature (IUCN). Their populations are declining due to habitat loss, degradation, and persecution. Habitat loss stems primarily from conversion of grasslands to agriculture and overgrazing by livestock. Direct persecution occurs when they are mistakenly targeted by farmers who perceive them as a threat to livestock, though their primary diet is pests. Conservation efforts are crucial to ensure the survival of this magnificent bird. Protecting their habitat and educating local communities are key steps to securing their future. The conservation efforts are vital to prevent the population declining further.
The Secretarybird in Culture and Symbolism
Beyond its ecological role, the Secretarybird holds cultural significance in Africa. It appears on the coat of arms of both Sudan and South Africa, symbolizing vigilance and power. In South Africa, it also represents the nation’s ability to rise above challenges and protect its resources. It represents strength, beauty and unique adaptation to the environment.

Frequently Asked Questions (FAQs)
What are the main predators of the Secretarybird?
Adult Secretarybirds have relatively few natural predators due to their size and formidable defenses. However, chicks and eggs are vulnerable to predators such as jackals, hyenas, and large raptors. The nests are often built in acacia trees which offers protection but does not completely eliminate the risk.
How does the Secretarybird avoid being bitten by venomous snakes?
Secretarybirds employ several strategies to avoid snakebites. They often use their wings as shields to deflect strikes, and their thick scales on their legs provide some protection. Most importantly, their speed and agility allow them to avoid bites while delivering powerful kicks.
What is the lifespan of a Secretarybird?
In the wild, Secretarybirds typically live for 15-20 years. In captivity, they can live longer, sometimes exceeding 25 years, provided they receive proper care and nutrition.
How does the Secretarybird build its nest?
Secretarybirds build large, platform nests of sticks and grass, typically in acacia trees. The nests can be quite substantial, often measuring several feet in diameter. The nest is typically reused over several years.
How many eggs does a Secretarybird lay?
A typical clutch size for Secretarybirds is 1-3 eggs. The eggs are incubated by both parents for approximately 45 days.
How quickly do Secretarybird chicks develop?
Secretarybird chicks are altricial, meaning they are born relatively helpless and require extensive parental care. They fledge (leave the nest) after about 65-80 days, but they continue to rely on their parents for food and protection for several more weeks.
Where can you find Secretarybirds in Africa?
Secretarybirds are found throughout sub-Saharan Africa, in a variety of open habitats, including grasslands, savannas, and lightly wooded areas. They are most commonly seen in areas with abundant prey.
Are Secretarybirds migratory?
Secretarybirds are generally non-migratory, although they may move locally in response to changes in food availability or environmental conditions. They often stay in their territory throughout the year.
What is the average weight of a Secretarybird?
Secretarybirds typically weigh between 3.3 and 9.5 pounds (1.5 to 4.3 kilograms). Males tend to be slightly larger than females.
What role do Secretarybirds play in the ecosystem?
Secretarybirds play a crucial role in controlling populations of snakes, rodents, and other pests. Their presence contributes to the health and balance of the ecosystem. By keeping snake populations in check, they reduce the risk of snakebites to humans and livestock.
How can I help protect Secretarybirds?
You can support conservation efforts by:
- Supporting organizations that work to protect their habitat.
- Educating others about the importance of Secretarybirds and their role in the ecosystem.
- Promoting sustainable land management practices. Avoiding the support of developments that might harm its ecosystem.
What is the significance of the Secretarybird’s name?
The name “Secretarybird” is believed to have originated from the bird’s crest of feathers, which resemble the quill pens that secretaries once tucked behind their ears. It’s a testament to observational naming based on physical appearance. This connection underscores the bird’s distinctive profile and memorable character. What is the African snake killing bird also stands tall and is easily recognised.
