The Common Myna (Acridotheres tristis) in Faisalabad city mainly nests in tree
cavities. Mating was observed from March through May. Egg laying took place in
mid-April. Incubation period lasted for 13 to 14 days. The incubating pairs spent
only 32% of the total day light hours inside the nest cavities. The young were
fledged after 18 to 25 days. Both the parents brought food (mainly insects) for the
nestlings. The parents made 22 visits to an average nest in an hour to feed the
young. The Myna fiercely competed for defending the nest among themselves as
well as with the Rose-ringed Parakeets. About 43% of the territorial defense involved Common Myna and 35% Rose-ringed Parakeet. Generally, the Myna produced two broods in a season and the breeding season lasted from March through
September.
