Cuculus canorus
The Common Cuckoo (Cuculus canorus) is a medium-sized avian enigma, typically measuring 32-34 cm in length with a wingspan of 55-60 cm and weighing 100-130g. Adults are characterized by slate-grey upperparts, head, and chest, contrasting sharply with white underparts finely barred with dark grey. A distinctive field mark is its silhouette in flight, often mistaken for a small hawk like the Eurasian Sparrowhawk, featuring pointed wings and a long, graduated tail. Sexual dimorphism is subtle, w...
Primarily found in open wooded habitats including deciduous and coniferous woodlands, scrublands, heathlands, and often near grasslands or reedbeds, typically at lower to mid-elevations but up to high mountain altitudes in parts of its range.
Their diet consists primarily of large insects, particularly hairy caterpillars, which are often avoided by other birds, but also includes beetles, grasshoppers, and other insect larvae. They forage by gleaning from vegetation or snatching prey from the ground.
Common Cuckoos are largely diurnal and secretive, often betraying their presence through their distinctive calls rather than visual sightings. Males establish and defend territories with their characteristic "cuck-oo" call, while females are more nomadic, constantly searching for suitable host ne...
The Common Cuckoo boasts an expansive Palearctic breeding range, covering almost all of Europe and temperate Asia, from the Atlantic coast of Western Europe eastwards across Siberia to Japan, and south to northern Africa and the Himalayan foothills. They are classic long-distance migratory birds,...
