Chan Boon Hong was at Jurong Eco Garden one evening when he noticed a few Blue-tailed Bee-eaters (Merops philippinus) diving into the water. They immediately emerged from the water, flew to a nearby parch to dry their feathers and preen.
There were no evidence of the bee-eaters catching fish or water insects. They were simply taking a bath.
Each bee-eater made a few dives before flying off.
An earlier post managed to show the Blue-tailed Bee-eater actually caught something after diving into the water.
Fry (1984) reported the bird taking the small, surface feeding mosquito fish (Gambusia affinis) when a vertebra of the fish was detected in a pellet regurgitated by the a Blue-tailed Bee-eater. This fish, native to southern United States and Mexico, is now found throughout the world, used mainly to control mosquito larvae in freshwater ponds and lakes.
