They have a rich variety of songs and calls, including longcalls which allow them to communicate long distances in the forest.

Blue-throated bee-eaters practice asynchronous brooding, which means that chicks hatch at different times, often pairing with siblicide.

One notable seasonal spring migration occurs from Sumatra, across the Strait of Malacca, and ending on the west coast of Malaysia.

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.

The blue-throated bee-eater was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the current binomial name Merops viridis.

[6] On 26 May 2013, this species was sighted by sasidharan manekkara and photographed from, the breeding colony of blue-tailed bee-eater (Merops philippinus)near , Kannur, Kerala South India.

[9] Their habitat includes a wide variety of flat plains, such as farmland, suburban gardens, riversides, dunes, and sandy clearings.

[7] Colony sizes range from 50 to 200 pairs or living completely solitary in the open country.

[10] Those chicks who are older have time to grow more contour feathers, protecting them from damaging attacks.

[10] Siblicide is common among other birds to increase the larger and older chick's survival with greater access to food by the parents.

[6] A large percentage of the blue-throated bee eater's diet consists of dragonflies with highest success rate of their catches in sunny conditions.

[12] Once reaching land, they would rest on the lighthouse and tree branches for up to ten minutes before continuing eastward.

[12] The high number observations of bee-eaters were most likely due to the strong thermals that formed over Sumatra, allowing them to soar over the sea-breeze with ease.

They have been characterized as "least concern" in terms of conservational status, which is determined by a combination of range distribution, population stability, habitat loss, and potential threats.
