Blue-throated bee-eater, also known as Blue-throated bee-eater, has 2 subspecies.

Blue-throated bee-eaters often move alone or in small groups, often flying in the sky to find food, and often resting on trees or wires.

The migration time of the blue-throated bee-eater is from April to May in spring and from September to October in autumn. It mainly feeds on various bees and also eats other insects. It likes to stay on the perch and wait for passing insects; occasionally pick up insects from the water or the ground. Call: It makes a rapid trill of kerik-kerik-kerik when flying.

The breeding season of the blue-throated bee-eater is from May to July. During the breeding season, the birds gather in sandy areas and build nests in caves. Each nest lays 4 eggs, and the size of the eggs is 21.5~24.6 mm × 19~20.5 mm.

The global population of blue-throated bee-eaters has not been quantified, but it is widely distributed in its native habitat and is a common species (del Hoyoet al. 2001). There are less than 10,000 breeding pairs in China (Brazil 2009), and the number is relatively abundant in some local areas.
