The Ethiopian Bee-eater, also known as the Lafresnay’s Bee-eater, is a striking bird species native to the African continent. With its vibrant colors and impressive hunting techniques, this bird has caught the attention of bird enthusiasts worldwide.

In this article, we will delve into the identification, plumages, and molts of the Ethiopian Bee-eater.

Identification

Field

Identification:

The Ethiopian Bee-eater is a medium-sized bird that typically measures around 29cm and weighs about 55-65 grams. It has a long tail and a pointed bill used for capturing small flying insects, which are its main source of food.

The bird is brightly colored, with a greenish-blue head, wings and back; a reddish-brown throat, breast and belly; and a black stripe running across its eyes. Similar Species:

Though the Ethiopian Bee-eater is easily identifiable due to its unique features, there are other bee-eaters species that are similar in size and colors.

The Blue-cheeked Bee-eater and the Arabian Green Bee-eater share the same colors as the Ethiopian Bee-eater. However, the Arabian Green Bee-eater has a shorter tail and a shorter bill while the Blue-cheeked Bee-eater has blue cheeks.

Plumages

The Ethiopian Bee-eater has two primary plumages: breeding and non-breeding plumages. The breeding plumage of the Ethiopian Bee-eater is characterized by elongated central tail feathers that extend about 5cm beyond the other feathers.

The throat, breast, and belly are reddish-brown, while the crown, back, and wings are greenish-blue. The bird’s eyes are surrounded by a black stripe that runs over the ear coverts and below the eye.

The non-breeding plumage of the Ethiopian Bee-eater is similar to its breeding plumage, but the brown coloration of the throat, breast, and belly is less intense. The elongated central tail feathers are also shorter.

The bird’s upperparts and wings are more greenish, although some greenish-blue feathers remain. The black stripe around the eyes is also less pronounced.

Molts

The Ethiopian Bee-eater undergoes two molts a year – the prebasic and prealternate molts.

The prebasic molt occurs after the breeding season and before the non-breeding season.

During this time, the bird replaces its worn-out feathers with fresh ones, ensuring that they are in good condition before the challenging non-breeding period. The prebasic molt is gradual, with feathers on various body parts replaced one by one, and it takes a few months.

The prealternate molt, on the other hand, occurs before the breeding season. During this time, the bird replaces its non-breeding plumage with breeding plumage.

The prealternate molt is relatively quick, usually taking a few weeks.

Conclusion

In summary, the Ethiopian Bee-eater is a colorful bird that is easily identifiable. Its unique features make it stand out from its similar species.

The bird has two primary plumages – breeding and non-breeding – and undergoes two molts a year. Understanding these characteristics can help bird enthusiasts identify, locate, and appreciate the beauty of this fascinating bird species.

It is often seen perching on tree branches or other elevated perches, waiting for a chance to catch its prey in mid-air.

Movements and Migration

The Ethiopian Bee-eater is a non-migratory bird, and as such, it does not undertake significant movements across long distances. However, within its range, the species is known to exhibit seasonal movements, especially during the non-breeding season.

During this time, the bird may move from areas with less favorable weather conditions to regions with more favorable climatic conditions. For example, in West Africa, the species has been observed to move from the dry interior savannas to wetter regions along the coasts during the non-breeding season.

The Ethiopian Bee-eater does not exhibit any significant altitudinal movements, preferring to stay within its preferred habitats. However, studies show that the species can move locally within its home range to exploit available food resources.

For instance, during dry periods, the bird may move from areas with low insect density to water sources, which are often swarmed with insects. This movement is necessary to ensure the bird’s survival during times of food scarcity.

Although the Ethiopian Bee-eater is not a migratory bird, it may undertake short-distance movements within its range. For example, juvenile birds may disperse from their natal sites to establish new territories in areas with suitable habitats.

These movements are essential for maintaining genetic diversity and preventing inbreeding within the population. In general, the Ethiopian Bee-eater’s movements are seasonal and are primarily driven by the availability of food and favorable climatic conditions within its range.

The bird is highly adaptable and will adjust its movements and behavior to respond to changes in its environment. This flexibility is crucial for the species’s conservation, considering the ongoing habitat loss and degradation within its range.

Conclusion

Behavior

Locomotion:

The Ethiopian Bee-eater is an agile and fast flyer, able to execute impressive aerial maneuvers while hunting for insect prey. The bird uses its long wings and pointed bill to make quick turns and rapid ascents and descents.

When perched, the bird has a sleek, streamlined posture, and it is often seen perching on branches, rocks, or other elevated perches. Self Maintenance:

The Ethiopian Bee-eater maintains its feathers and bill through preening, a process that involves using its beak to comb through its feathers and remove any dirt or debris.

The bird also bathes regularly, usually in shallow water sources such as muddy pools and puddles. Agonistic

Behavior:

The Ethiopian Bee-eater exhibits agonistic behavior during territorial conflicts or competition for resources.

Agonistic behavior includes displays such as wing flapping, tail bobbing, and vocalization. When confronted by an intruder, the Ethiopian Bee-eater will often attempt to intimidate the opponent rather than engage in physical combat.

Sexual

Behavior:

During the breeding season, males engage in courtship displays to attract females. These displays include vocalizations, aerial acrobatics, and offerings of insect prey to the female.

Once a pair has bonded, the male will defend the territory and help the female excavate a nesting burrow.

Breeding

The breeding season for the Ethiopian Bee-eater varies across its range, with the timing often dependent on local climatic conditions. In West Africa, breeding usually occurs from April to June, while in East Africa, breeding can occur from October to December.

The Ethiopian Bee-eater is a colonial breeder, nesting in groups of up to several hundred individuals. The bird excavates its nesting burrow in moist, sandy soils, usually near water sources.

The burrow can be up to 1.5 meters long, and it ends in a nesting chamber where the female lays her eggs. The female usually lays between 3 and 5 eggs, which are incubated by both parents for a period of around 20 days.

Once the chicks hatch, they are fed by both parents, who regurgitate insect prey into the nest. As the chicks grow, they become more demanding, and the parents must forage for ever-increasing amounts of food to satisfy their hunger.

The chicks fledge after about 28 days and become independent a few weeks later.

Demography and Populations

The Ethiopian Bee-eater is a relatively common bird species throughout its range, and there are no major global threats to its populations. However, local populations are at risk from habitat loss, hunting, and pollution.

Studies conducted in West Africa have shown that the Ethiopian Bee-eater’s population has declined in recent years due to habitat loss and hunting pressure. In contrast, populations in southern Africa are increasing, possibly due to changing climatic conditions and the expansion of suitable habitat.
