The Sunda Cuckoo (Cuculus lepidus) is a species found in the Sundaic region of Southeast Asia, often considered a distinct species or subspecies of Horsfield's Cuckoo. It primarily inhabits montane forests and is a brood parasite.
Where to spot
Endemic to the mountainous regions of the Greater Sunda Islands (Sumatra, Borneo, Java) and the Malay Peninsula. Found in montane and hill forests, generally above 1000m elevation.
How to spot
Listen for its characteristic deep, resonant call, which is similar to Horsfield's Cuckoo but may have subtle differences in cadence or tone. Visually, it is similar to Horsfield's Cuckoo, with grey upperparts and barred underparts, often seen in dense forest canopy.
When to spot
Can be observed year-round within its resident range. Most active and vocal during the local breeding season, which varies by region but is often tied to periods of increased insect activity.

This cuckoo is typically found at higher elevations than its close relatives, adapted to the cooler and often cloud-shrouded montane environments of the Sunda Islands.
