Spotted
The Common Hawk-cuckoo is a widespread Asian cuckoo, also known for its distinctive 'brain-fever' call, though subtly different from the Large Hawk-cuckoo's. It remarkably mimics the Shikra (*Accipiter badius*), a common Asian sparrowhawk, in appearance.
Where to spot
Found across the Indian subcontinent and parts of Southeast Asia, common in open woodlands, gardens, cultivated areas, and forest edges.
How to spot
Listen intently for its characteristic 'brain-fever' call, which typically ascends in pitch and volume with each repetition. Visually, look for its hawk-like appearance, particularly its barred underparts, and its habit of perching upright in trees.
When to spot
Most vocal during the breeding season (hot summer months). Resident in much of its range, with some migratory movements in northern populations.
