Long-crested Eagle Physical Description

Long-Crested Eagles have an entirely dark brown to blackish appearance, with exceptions for the white marking at their primary feathers’ base, and grayish-barred tail with white edges. They have a distinctive, long, flabby crest at the rear of their crown, in which they got their name. Eyes are bright yellow but may appear darker in females. Feet and cere are yellow but duller to whitish in males. Juveniles or immature birds look like adults, but sport a paler plumage, while crest is yet to develop. They are one of the smaller eagles, growing from 21 to 23 inches or 53 to 58 centimeters and weighing 912 to 1500 grams. Females are relatively larger and heavier.

Where can they be spotted?

Long-crested Eagles are found across sub-Saharan Africa, such as in Botswana, Ethiopia, Namibia, South Africa, Mozambique, Senegal, and Zimbabwe. These birds thrive in moist woodlands, forest edges, marshes, farmlands, woodlands, pastures, plantations, and orchards. They avoid arid areas,

Interesting Facts You Should Know About the Long-crested Eagle

Long-crested Eagles feed almost mainly on rodents, which is believed to take about 90% of their diet, making them beneficial to farmers. Other food items they consume include fish, lizards, arthropods, and small birds. Occasionally, they also eat mulberries and wild figs. They hunt from a perch, keenly observing their prey, and then swoops down to catch them once detected. These birds have a wide gape, and swallow their prey whole.

They are monogamous birds, and courtship displays are characterized by rocking flights, steep dives, and calling. Breeding season occurs throughout the year but is generally linked to the population of rodents and, in turn, rainfall. Egg-laying season peaks from July to November.

Both sexes construct the nest, which is a cup made of sticks, with green leaves interior. They build the on tree trunks found in the middle canopy. The most common trees used are Acacia, Eucalyptus, Musasa, Willow, and Fig.

The female long-crested eagles will lay 1 to 2 eggs, which she will solely incubate for 42 days, while the male hunts and provides her food. Chicks hatch 15 days apart, which will also be fed by the male initially. After 53 days, the chicks will fledge before leaving parental care 2 to 3 months later.

Long-crested Eagles do not face much persecution as they are deemed beneficial by farmers in controlling the rodent population. However, their number is in threat due to the destruction of habitats and collisions with vehicles and power lines. Still, the species does not reach decline thresholds, and they are evaluated as Least Concern (LC) under the IUCN Red List.
