Blue-throated bee-eaters practice asynchronous brooding, which means that chicks hatch at different times, often pairing with siblicide. Older chicks are not only larger and able to withstand larger wounds from other siblings, but also have the ability to monopolize the food they are fed by parents. There has been several observations of migration between islands in southeast Asia or onto mainland of Asia. One notable seasonal spring migration occurs from Sumatra, across the Strait of Malacca, and ending on the west coast of Malaysia. They also migrate from southeast Asia to breeding grounds in western China during breeding season.
Conservation status of the blue-throated bee-eaters is of "least concern" due to their large distribution and stability of its population as of 2016. However, deforestation may be its biggest threat, destroying its habitat and decreasing other bird diversities.
