Clamator glandarius
The Great Spotted Cuckoo (Clamator glandarius) is a charismatic and intriguing member of the cuckoo family, characterized by its elegant, slender build, long tail, and distinctive shaggy crest. Adults typically measure 35-39 cm (14-15 in) in length with a wingspan of 60-65 cm (24-26 in), weighing between 120-160 grams. Their plumage is largely grey-brown above, adorned with prominent white spots on the wings, a grey head, and white underparts, often with a creamy wash on the throat and breast...
Primarily inhabiting warm, open woodlands, savannahs, scrublands, orchards, and agricultural areas, the Great Spotted Cuckoo thrives in mosaic landscapes, often in proximity to its corvid hosts. It can be found from sea level up to moderate elevations, typically around 2,000 meters.
Strictly insectivorous, their diet consists mainly of large insects such as caterpillars (including hairy, unpalatable species), beetles, grasshoppers, and mantises. They forage both arboreally and by gleaning from the ground.
This diurnal cuckoo frequently perches conspicuously on elevated spots like tree branches or power lines, scanning its environment. Its most notable behavior is obligate brood parasitism; females lay 12-18 eggs per season in the nests of corvids, particularly magpies. Uniquely, Great Spotted Cuck...
The Great Spotted Cuckoo maintains a widespread but somewhat fragmented breeding range spanning southern Europe, North Africa, and extending across the Middle East into Western Asia. In Europe, breeding populations are found from the Iberian Peninsula eastward through southern France, Italy, and ...
