Raising three young captive belted kingfishers (Megaceryle alcyon) from nestlings until they were able to catch their own prey brought out points regarding their biology. These, in terms of their natural history, were: (1) that nestlings eject liquid excreta forcefully up against nest walls in alt directions, then bury them by a constant habit of rapping that knocks down sand .and dirt; (2) young kingfishers can dive and catch prey under water within a week of fledging without 'being taught by parents; (3) kingfishers, when about to dive, appear to be using the two white spots in front of the eyes as sighting devices along the line of the bill to fix their prey and, by doing so, possibly to correct for the refraction of water.
