Information on provisioning behavior of birds in the Indian subcontinent is almost negligible. We studied provisioning of nestlings of the Oriental Magpie-robin (Copsychus saularis) in 11 nests in relation to brood size, nestling age, and time of day during March-July 2006. Both parents fed the nestlings. However, the rate of provisioning trips by females was higher (t = 9.51, df = 10, P < 0.01) than for males. Brood size and time of day did not affect the provisioning rate. Age of nestlings was an important factor affecting rate of parental provisioning. Nestlings were fed more as they became older and there was correlation (Spearman's rho = 1) between parental provisioning trips and nestling age.
