Abstract
Artificial (Wooden) nest boxes were successfully adopted by Spotted Owlet (Athene brama) and Common Myna (Acridotheres tristis) which accomplished egg laying in 9.80 and 74.50% boxes, out of total 51 boxes, installed at eight different sites at one location. Egg laying by Common Myna was accomplished repeatedly for second and third time in 23.53 and 3.92% nest boxes respectively after successfully raising the previous brood. Breeding success of 35.71 and 77.86% was achieved in Spotted Owlet and Common Myna. None of the birds adopted and accomplished breeding in 33 boxes installed at two different sites, 15 and 18 boxes at each site, at another location owing to the dominance of Barn Owl, Tyto alba and Tree mouse, Vandeleuria oleracea dumeticola at the respective sites. Timing and site of installation served as contributing factors while predation and parasitism acted as limiting factors in nest box breeding. Higher breeding performance of Common Myna was recorded in artificial nest boxes than in natural cavity nesting.
