Secretarybird (Sagittarius serpentarius) lives in open savanna and grassland across Sub-Saharan Africa. It feeds on small mammals insects. Its conservation status is Endangered.
Fascinating facts about the Secretarybird
- Standing up to 1.3 m tall, the secretarybird is taller than any other raptor, with legs that are nearly twice as long as those of an eagle of the same mass. Its tarsus averages 31 cm and its tail reaches 85 cm, giving it a height of as much as 1.3 m (4 ft 3 in). This extreme leg length lets it strike prey with a force five times its own body weight in just 10-15 ms, a hunting adaptation that lets it stun snakes and other fast-moving animals without needing talons. By relying on powerful stomps rather than grasping, the bird can dominate ground prey that would overwhelm typical birds of prey.
- A secretarybird can walk up to 30 km a day, yet it only flies when forced or to reach a roost. It paces at 2.5-3.0 km/h, taking about 120 steps per minute, and can soar to 3 800 m using thermals. This ground-based lifestyle lets it cover vast savanna expanses while staying hidden in low grass, but also brings it into frequent contact with power lines, fences and expanding farms, increasing its exposure to human-made threats.
- Secretarybirds lay only one to three eggs, each about 78 mm × 57 mm and weighing 130 g, and the chicks hatch after roughly 45 days. Because the eggs hatch 2-3 days apart, the youngest nestling often starves if food is scarce, and in a clutch of three the smallest chick usually dies of starvation. This low reproductive output, combined with a long 42-46 day incubation and a fledging period of 64-106 days.
- Although once listed as Least Concern, recent surveys show the secretarybird has vanished from 94 % of its historic road-survey encounters in Kenya and suffered an 80 % decline across four African regions. The IUCN now classifies it as Endangered, and some researchers argue it should be upgraded to Critically Endangered.
- The bird's diet is a grab-bag of insects, rodents, small birds, amphibians and snakes, but it rarely eats carrion. Its powerful beak and huge gape let it swallow prey whole, while its short, blunt toes cannot grasp. To digest the meat, the secretarybird has a short foregut, a dilated crop and a non-muscular gizzard, relying on regurgitated pellets 40-45 mm in diameter and 30-100 mm in length to expel indigestible parts.

About the Secretarybird
In the scorching savannas, the Secretarybird strides with purpose, its long legs devouring distance as it scans the terrain for unsuspecting prey, its crest of long feathers quivering in the breeze like a quill pen held aloft. With each deliberate step, this majestic hunter commands its domain, a true monarch of the grasslands, its sharp eyes ever-vigilant for the telltale rustle of a snake or the frantic scurry of a rodent. As it moves, the Secretarybird embodies a paradox of elegance and ruthlessness, a testament to the enduring power of evolution in this unforgiving yet beautiful landscape.
