Habitat

The Blue-tailed Bee-eater is a bird species that inhabits various habitats in its range, including open woodlands, forests, scrublands, savannas, grasslands, marshes, and wetlands. It prefers open areas with scattered trees and bushes, where it can easily hunt for insects mid-flight.

In South Asia, Blue-tailed Bee-eaters can be found in areas with well-developed river and lake systems, which provide them with a rich source of insects. In Southeast Asia, they are often found in agricultural areas, where they can feed on the insects that are attracted to irrigated crops.

In Australia, the species is found in coastal areas, which offer nesting sites in sandy riverbanks and dunes.

Movements and Migration

The Blue-tailed Bee-eater is a migratory species, with populations breeding in summer and wintering in the warmer climates of Southeast Asia and the Indian subcontinent. Different populations follow different migration routes, with some crossing the Himalayas and others traveling long distances over the sea to reach their wintering grounds.

The timing of migration can vary between populations. In India and Southeast Asia, Blue-tailed Bee-eaters begin their breeding season in March and April, with adults arriving from their wintering grounds.

They then leave again in September and October, with some moving as far as southern Africa and Madagascar. In contrast, populations in Australia only stay for a limited period from August to March, with some birds dispersing inland after breeding.

During migration, the Blue-tailed Bee-eater forms large flocks, with individuals often gathering in the hundreds. These flocks travel together to their wintering grounds, feeding on insects along the way.

The bird’s strong flying ability allows them to cover long distances rapidly, so that they can reach their destinations before food becomes scarce. Blue-tailed Bee-eaters often follow the same migration routes year after year, using landmarks or the position of the sun to help them navigate.

Some individuals may even use the magnetic field to orient themselves during migration, with studies suggesting that they may have a magnetic sense that allows them to detect changes in Earth’s magnetic fields.

Diet and Foraging

The Blue-tailed Bee-eater is a specialized insectivore, feeding primarily on flying insects such as dragonflies, bees, wasps, and flies, which it catches mid-air. The bird’s diet is supplemented with other small insects, including beetles, bugs, and grasshoppers.

Feeding

Blue-tailed Bee-eaters hunt their prey in an aerial display, often flying in pairs or small flocks. During the hunt, the bird flies erratically, making sudden turns and swoops in the air to catch its prey.

Once captured, the insect is taken to a nearby perch, where it is repeatedly hit against the branch to remove the wings and legs before being swallowed whole. The bird’s sharp, pointed beak is perfect for catching insects mid-flight, allowing it to snatch prey with ease.

In addition, the Blue-tailed Bee-eater’s eyes are strategically placed on the sides of its head, allowing it to have a wide field of vision, which is important for spotting prey in flight.

Diet

The Blue-tailed Bee-eater’s diet is strongly influenced by availability, with the bird often feeding on the most abundant insects in a given area. The species is known to migrate to find abundant insect populations, moving from one area to another to follow food availability.

Their diet also changes depending on the breeding season. During nesting, the birds feed on larger insects, such as grasshoppers, to provide enough protein for their growing chicks.

In contrast, during the non-breeding season, they consume smaller insects such as midges and termites.

Metabolism and Temperature Regulation

Blue-tailed Bee-eaters have a high metabolic rate, which allows them to fly great distances and maintain their body temperature. In addition, the bird has various adaptations that help it regulate its body temperature.

For example, the bird may lower its metabolic rate during the night or early morning to conserve energy. The bird’s plumage also plays an important role in temperature regulation.

In hot weather, the Blue-tailed Bee-eater spreads its wings, exposing its underwing feathers and reducing body temperature through evaporative heat loss.
