摘要：The Plaintive Cuckoo (Cacomantis merulinus) is a widespread brood parasite in Asia, but no data on host species utilization in Bangladesh exist. By searching for nests of all possible host species of the Plaintive Cuckoo at Jahangirnagar university campus, north of Dhaka, we were able to determine which hosts were used in this area. We found that the Common Tailorbird (Orthotomus sutorius) was the only potential host used by Plaintive Cuckoos, and parasitism rate was rather high (31.3 %, n = 16). However, both host and cuckoo breeding success was poor (0 %, n = 16) due to frequent nest predation. Details on host and cuckoo egg appearance are provided. Our findings indicate that Common Tailorbirds are common hosts of the Plaintive Cuckoo in Central Bangladesh.
