Every morning since 27th March 2018, a family of Javan Mynas (Acridotheres javanicus) comprising two adults and a recently fledged juvenile, walked through my garden to forage. This was followed by a return walk in the evenings. The characteristic begging cries of the juvenile announce their presence. After all, they nest under the roof of my back-neighbour’s house LINK. The video below shows the adults foraging with the 10 days old fledgling.
The adults brought the juvenile through my garden and out to the main road in front. From there they moved along the pavement, sometimes ending in a wayside tree where the adults flew in fruits like those of the Singapore Rhododendron (Melastoma malabathricum) nearby to the noisy juvenile. The video below records the adults with the 12 days old fledgling foraging.
These were teaching sessions on how to survive outside the nest: foraging for food, recognising potential predators and how to avoid them. The adults walked around, picking up food to eat. The juvenile followed and beg loudly for food. Once in a while an adult would pass something to the juvenile. With time the juvenile learnt to pick up food for itself but it still kept on begging the adults for food. The video below shows the adults with the 15 days old juvenile.
By day 17 the juvenile was seen following one adult. There were no begging cries. The juvenile was feeding by itself. The following day only the two adults were seen foraging in the garden. The juvenile was nowhere in sight.
Did the juvenile moved off to be independent of the adults? At day 18? If so, the fledgling period was only 18 days, compared to the earlier 25 days, see HERE.
