Wooden nests are being utilized as a common conservation tool to augment the population of secondary cavity nesting birds that are beneficial to agriculture. Some species of birds are natural predators of insects which keep constant check on growing insect population. Acceptance of wooden nests by Common Myna (Acridotheres tristis) for successful breeding and rearing of young ones was studied at four different habitat types i.e. Type A (random trees in agricultural fields), Type B (tree lines along with agricultural fields), Type C (trees in building complexes) and Type D (agro-forestry plantation). Habitat type A was the most preferred for wooden nest occupancy as it supported diverse animal/insect fauna. Common Myna was found to prefer wooden nests installed on Dek (Melia azedarach) and Tahli (Dalbergia sissoo). The clutch size varied from 3–6 in the artificial/wooden nests. Egg incubation period was found to be 15 days. The hatching success was recorded to be 96.59% and 95.73% in the breeding seasons in the years 2010 and 2011 respectively.
