Found in woodland, heathland, farmland with hedges, marshes with scattered bushes. "COO-koo" song (like a cuckoo clock) often given from open perch. Note long wings and tail, barred belly, rather small bill. Flight direct and often low, suggesting a hawk or falcon. Extremely similar in appearance to various other Cuculus cuckoos across its range; note the combination of white vent, staring yellow irises, and overall large size. Lays eggs in nests of other birds, particularly pipits and reed warblers, which raise the young cuckoos.
