Leptosomidae
Madagascar’s Mysterious Aerial Predator: The Cuckoo-Roller (Leptosomus discolor) is one of Madagascar’s most enigmatic birds, belonging to its very own family, Leptosomidae. Found only on the island and nearby Comoros, this unique species has puzzled ornithologists for years, with its uncertain evolutionary relationships and unusual characteristics. With its stocky build, broad head, and striking sexual dimorphism, the Cuckoo-Roller is unlike any other bird. Males sport an iridescent green and purple sheen on their upperparts, contrasting with pale underparts, while females are brown with streaked undersides. Their powerful, hooked bill is perfect for snatching up large insects, chameleons, and small reptiles from the treetops. Often seen soaring high above Madagascar’s forests, Cuckoo-Rollers glide effortlessly, their slow, buoyant flight resembling that of raptors. They are typically silent, but during the breeding season, males produce deep, echoing calls that resonate through the canopy. Despite their apparent dominance as canopy predators, much about their behavior remains a mystery. They nest in tree cavities, but details of their breeding habits are still poorly understood. Habitat destruction is a concern, but for now, this ancient relic of Madagascar’s evolutionary past continues to rule its aerial domain, an enduring symbol of the island’s unique biodiversity.
