On the Ecologicy of Indian Cuckoo Cuculus micropterus in Luya National Nature Reserve,Shanxi Province
We studied the ecology of Indian Cuckoo Cuculus micropterus in Luyashan National Nature Reserve of Shanxi Province during May to August each year from 2009 to 2011.Upon arrival,cuckoos occupied the low mountains and sparse woods near villages.Cuckoo activity was alert and secretive,their calls were often heard but few were seen.Maximum population density was recorded in June and July,at 1.17 birds/km and 1.25 bird/km,respectively.Minimum density was in August,at 0.47 birds/km.Average population density was 0.89 birds/km.Indian Cuckoo is a nest parasite,laying eggs in nests of Garrulax davidi.G.davidi incubated Indian Cuckoo eggs and brooded their chicks.We observed on Indian Cuckoo that laid two eggs weighing 3.3 g and 3.5 g,and measuring 22×17 mm and 23×18 mm.The eggs hatched after 18 days and G.davidi fed the nestlings for 14 days when the chicks fledged.Indian Cuckoo fed mainly on insects,which accounted for 95.5%of their diet. Dendrolimus punctatus was the most common insect prey,accounting for 24.1%of the total weight of insect food.Indian Cuckoo is an important species for agriculture and forestry,and should be protected.
