In June 2013, Goh Juan Hui documented a variety of food the adult Collared Kingfishers (Todiramphus chloris) brought back to feed the young at the nest. The nest was a small opening of about 4cm diameter found on the vertical wall of a monsoon drain at the forest margin (below left). This opening was towards the top of the wall, well above the water level during rainy periods.
The prey the adults brought back consisted of insects, arachnids, caterpillars, lizards and earthworms (above right). Earthworms were brought back quite a few times immediately after an early afternoon shower.
Although sexes are not distinct, but based on the worn breast feathers from incubating the eggs, the supposedly female was less cautious when bringing food back to the nest. On the other hand the supposedly male was more cautious. The slightest movement within a 30 metre range would send him flying to a nearby tree to wait until the coast was clear. He also brought back bigger prey like the Common Flying Dragon (Draco sumatranus) (above and below).
Changeable Lizard (Calotes versicolor) (below left) and Garden Supple Skink (Lygosoma bowringii) (below right) were also part of the menu.
The image below shows the Collared Kingfisher with a grasshopper for the young.
Spiders were also brought (below left) as well as caterpillars (below right).

Magnificent Goh!
Enjoyed the post.

Great photographic documentation. And you do show what a wide range of prey is hunted by the kingfishers. But I wonder if all the items went into the chicks. There have been other documented cases of parent birds bringing back things that they could swallow, but which were unsuitable and far too big for their chicks. With species that build open nests, observers can see what happens to the food. Too bad that with kingfishers, we can only guess.
May be the big Lizard is for the parent only 🙂
More study is needed on the subject of unsuitable food for fledglings. It is known among birds of prey and some mammalian predators that the urge to feed or hunt is inhibited in the vicinity of the nest or den. This is so that the parents will not see their young as prey. Once prey is brought to the vicinity of the nest, if the chicks don’t eat it, there is a good chance that the parents might not either. Yes, there are exceptions to the rule. Perhaps some observers can contribute their opinions from what they have actually seen in the field.
