The lesser cuckoo is a small grey cuckoo with barred underparts, pointed wings and a long tail, resembling a reduced common cuckoo. It breeds across parts of Europe and Asia and migrates to Africa and Southeast Asia. It searches forest and wooded country for insects, especially caterpillars, and is a brood parasite whose females place their eggs in nests of small songbirds (Wikipedia, general species account). It is Nationally Least Concern (Thailand Red Data 2025).
