Can Secretary Birds Fly? Yes, But They Prefer Walking

Yes, secretary birds can fly—though they are far more likely to be seen walking across the African savanna than soaring through the sky. This often-misunderstood bird, known scientifically as Sagittarius serpentarius, possesses the physical ability to take flight, but its behavior and anatomy reflect a strong preference for life on the ground. The question can secretary birds fly is commonly asked by bird enthusiasts, wildlife observers, and students of avian biology, especially when first encountering this long-legged raptor that resembles a crane more than a typical bird of prey. While not built for prolonged aerial hunting like eagles or hawks, secretary birds do use flight for escaping danger, reaching nesting sites in trees, and covering large distances during dispersal or migration.

Biology of Flight in Secretary Birds

The secretary bird’s flight mechanics differ from those of other raptors due to its unique body structure. Standing up to four feet tall with exceptionally long legs adapted for walking, it has a relatively lightweight frame and broad wings that allow for powered flight. When taking off, the bird requires a short running start, flapping its wings vigorously to gain altitude. Once airborne, it flies with slow, deep wingbeats and can cover considerable distances—especially juveniles dispersing from their natal territories.

Despite being classified within the order Accipitriformes, which includes hawks, kites, and eagles, the secretary bird occupies a unique ecological niche. Its skeletal structure shows adaptations for terrestrial locomotion: elongated tarsometatarsus bones, reduced keel on the sternum (indicating less-developed flight muscles compared to strong fliers), and a center of gravity shifted forward to support upright walking. These traits explain why flight is used sparingly rather than as a primary mode of movement.

When and Why Do Secretary Birds Fly?

While predominantly terrestrial, secretary birds engage in flight under specific circumstances:

• Nesting and Roosting: They build large stick nests in acacia trees or other thorny vegetation, requiring flight to access these elevated platforms safely away from predators.
• Thermoregulation and Soaring: On warm days, secretary birds may soar at moderate altitudes using thermal updrafts, conserving energy while scanning vast areas for prey.
\li>Dispersal and Territory Establishment: Juvenile birds frequently fly long distances—sometimes over 100 kilometers—to establish new home ranges, particularly in response to seasonal changes or resource scarcity.
• Escape Behavior: When threatened by large predators such as leopards or hyenas, secretary birds will take flight if walking or running isn’t sufficient to ensure safety.

Observations from field studies in South Africa and East Africa confirm that adult secretary birds typically fly only a few times per day, usually at dawn or dusk. Their flight duration rarely exceeds several minutes, reinforcing the idea that flight is functional rather than habitual.

Myths and Misconceptions About Secretary Bird Flight

A common misconception is that secretary birds cannot fly at all—a myth likely stemming from their crane-like appearance and ground-dominant lifestyle. Unlike true flightless birds such as ostriches or penguins, secretary birds retain fully developed wings capable of sustained flight. Another misunderstanding involves confusing them with storks or cranes, which belong to entirely different taxonomic groups. Despite superficial similarities, secretary birds are raptors, equipped with sharp talons and hooked beaks suited for killing snakes and small mammals.

The name “secretary bird” itself has sparked debate. One popular theory suggests it comes from the quill-like feathers on the back of its head resembling old-fashioned secretaries’ quill pens tucked behind the ear. Others argue it derives from the Arabic phrase saqr-et-tair (“hunter bird”), later misheard by European colonists. Regardless of etymology, the bird's image appears on the coat of arms of Sudan and features prominently in African folklore, symbolizing vigilance, protection, and justice—qualities linked to its snake-hunting prowess.

Habitat and Distribution Across Africa

Secretary birds inhabit open grasslands, savannas, and semi-arid regions across sub-Saharan Africa. Their range extends from Senegal and Somalia in the north to South Africa in the south. They avoid dense forests and true deserts, preferring ecosystems where visibility is high and prey is abundant. Countries such as Kenya, Botswana, Namibia, and Tanzania offer some of the best opportunities for observing secretary birds in their natural environment.

Due to habitat loss and human encroachment, the International Union for Conservation of Nature (IUCN) lists the secretary bird as Vulnerable, with populations declining across much of its historical range. Protecting open landscapes and reducing pesticide use—important for maintaining reptile and insect prey populations—is critical for conservation efforts.

How to Observe Secretary Birds in the Wild

For birdwatchers and ecotourists interested in seeing secretary birds—including witnessing them in flight—here are practical tips:

1. Visit National Parks During Dry Seasons: In countries like South Africa’s Kruger National Park or Etosha National Park in Namibia, dry months (May to October) reduce vegetation cover, making secretary birds easier to spot as they walk through open plains.
2. Dawn and Dusk Are Optimal Times: These are peak activity periods when secretary birds may take flight to reach roosting trees or begin morning patrols for food.
3. Use Binoculars or Spotting Scopes: Even when stationary, secretary birds stand tall enough to be visible from a distance. High-powered optics help identify subtle behaviors such as pre-flight posturing or wing stretching.
4. Join Guided Safari Tours: Experienced guides know common patrol routes and nesting locations, increasing your chances of witnessing rare behaviors like mating displays or juvenile dispersal flights.
5. Respect Wildlife Boundaries: Maintain a safe viewing distance to avoid stressing the birds. Disturbance can disrupt feeding patterns or cause unnecessary flight attempts that expend vital energy.

Cultural Significance and Symbolism

Beyond their biological uniqueness, secretary birds hold deep cultural significance across many African societies. Among the San people of southern Africa, the bird appears in rock art and oral traditions as a guardian spirit that wards off evil. In Ethiopian mythology, it symbolizes divine retribution against deceitful individuals, reflecting its role as a snake killer. The bird’s deliberate, almost methodical gait has led some cultures to associate it with wisdom, patience, and strategic thinking.

In modern times, the secretary bird has become an emblem of national pride. It appears on stamps, coins, and military insignia throughout Africa. Its presence in global zoological parks also raises awareness about African biodiversity and the importance of preserving open ecosystems.

Flight Patterns Compared to Other Ground-Dwelling Birds

To better understand the secretary bird’s flight behavior, consider how it compares to other birds that spend most of their time on land:

Bird Species	Flight Capability	Primary Locomotion	Flight Purpose
Secretary Bird	Capable of sustained flight	Walking/running	Nesting, escape, dispersal
Ostrich	Flightless	Running (up to 70 km/h)	None
Seriema (South America)	Limited flight; prefers running	Walking/running	Roosting, escaping predators
Kori Bustard
Strong flier despite weight	Walking	Mating displays, relocation
Greater Roadrunner	Short bursts of flight	Running	Climbing slopes, evading threats

This comparison highlights that while many ground-adapted birds retain some flight ability, the secretary bird stands out for combining raptor physiology with cursorial (running) adaptations—an evolutionary rarity.

Conservation Status and Threats to Flight-Dependent Behaviors

As human development fragments African savannas, secretary birds face growing challenges in performing essential flight-related activities. Nesting trees are cut down for agriculture or fuelwood, forcing birds to nest on the ground where eggs and chicks are vulnerable to predation. Power lines and wind turbines pose collision risks during flight, especially for inexperienced juveniles. Additionally, vehicle traffic along roadsides increases mortality during cross-terrain movements.

Conservationists recommend creating protected corridors between reserves to maintain connectivity for dispersing birds. Monitoring programs using GPS tracking devices have revealed detailed data on flight paths and altitudes, helping inform infrastructure planning to minimize impact.
