Freckled Nightjar

Overview

The freckled nightjar, or freckled rock nightjar (Caprimulgus tristigma), is a large, powerfully built species of nightjar in the family Caprimulgidae. It holds a wide yet patchy distribution throughout the Afrotropics and is currently classified as Least Concern by the IUCN.

Identification

• Large size with long wings and relatively short tails, appearing dark gray or nearly black from a distance with excellent camouflage for rocky surfaces.
• At closer range, white, cinnamon, and pale buff freckling is visible on the upperparts, while underparts are dark brown with whitish and cinnamon barring.
• Males possess small white spots on the four outer primaries and white tips on outer tail feathers, whereas females have fewer spots on primaries and lack white on tail feathers.
• Song consists of a whistle of two or three 'whow' notes repeated for 30 seconds or more, which may sound like a dog barking from a distance.

Habitat

This species occurs throughout sub-Saharan Africa in localized populations, being scarce in western Africa but more common in the east. In the southern part of the continent, it is a year-round resident of colder and drier areas, particularly in Zimbabwe, northern and eastern Botswana, western Mozambique, and eastern South Africa. During the day, it roosts on bare or lichen-covered rock surfaces, tolerating surface temperatures of up to 60 °C.

Diet

The diet primarily consists of flying insects such as moths, termites, and chafers, supplemented by beetles, butterflies, and other invertebrates. The bird has the largest gape of any nightjar, allowing it to swallow insects up to 3.5 cm long whole. It forages at dusk, dawn, and on moonlit nights by hawking insects during short flights over rocky landscapes and then gliding back to perches on boulders or rocky bank edges.

Did you know?

Research has shown that this species has the capacity to enter torpor during the coldest and driest parts of its annual cycle to conserve energy.
