Rufous-backed Kingfisher, male
The parents took turns bringing back a variety of prey items to feed their hungry youngs awaiting in the nesting tunnel which the parents painstakingly excavated earlier.
It was unclear just how many chicks were inside the nesting tunnel. Judging from the frequency of every about 1/2 hour and the number of food items brought back by the parents suggested at least 2-3 chicks were nesting
The exact number could only be determined during the fledging period when the young kings start to leave the nest one by one. That certainly would be a spectacular sight to watch, which I hope to witness one day.
It really makes me wonder how the chicks comsume such large food items. To put that in perspective, it's like for us to swallow a 10kg piglet at one go cause' they have got no teeth to chew their food.
Because all these feeding activities happen inside the confine of the nesting tunnel we have got no clue how they do it. Hopefully one day technology would helps us to learn more about them by allowing us to 'see' just what's going on inside the 'secret' chamber without causing any harm to them.
special note : these birds were captured in such intricate details only during their nesting period when you could approach it with amazingly close distance. The parents at all costs had to bring up their young during which they would returned to feed the chicks. They would perched at the exact same spot, stayed for a couple of seconds before disappearing into the nest hole with a rich variety of food source each time, only to emerge moments later to repeat the whole process all over again.
I have only seen it once during non-nesting period, and it was like a thousand miles away. One more inch closer, it would vanished in thin air.
