The landlocked country of Nepal boasts a plethora of flora and fauna, drawing nature enthusiasts from around the world. Dollarbird (Eurystomus orientalis) is one of the several bird species found here. Dollarbird, a member of the roller family, is also known as Oriental Dollarbird, Asian dollarbird, Dark Roller, Dollar Roller, Eastern Broad-billed Roller, and Oriental broad-billed Roller. The Dollarbird was formally described by the Swedish naturalist Carl Linnaeus in 1766 AD. In this article, we will delve into the captivating world of the Dollarbird.
Discovering the Dollarbird
Native to several parts of Asia, including Nepal, the Dollarbird is a medium-sized bird with striking blue-green plumage that shimmers under sunlight. These birds are primarily found in wooded regions, where they perch on high branches or dead trees. Their vibrant colors make them easily distinguishable from other birds inhabiting the area. The name "Dollarbird" comes from the distinct white circular markings on their wings, resembling silver dollars when in flight. These attractive birds have a gentle flight pattern that accentuates their unique beauty.
Feeding Habits and Behavior
Dollarbirds are known for their impressive aerial acrobatics while hunting for food. They mostly feed on insects such as beetles, cicadas, and butterflies. These agile creatures catch their prey mid-flight using their strong beaks before returning to their perches to devour it. Dollarbirds are generally solitary or found in small family groups and communicate using guttural, chattering calls. Although they are not considered highly vocal birds, they do become more prominent during mating periods when they produce a range of interesting call variations.
Migration and Breeding Patterns
The Dollarbirds found in Nepal typically follow seasonal migration patterns. They arrive in Nepal around April or May for breeding before migrating back to southern regions around September. Their breeding season mostly coincides with the warm monsoon months in Nepal. During nesting time, Dollarbirds will aggressively defend their territory from potential competitors. They tend to choose tree cavities or hollows as nesting sites and lay two to four eggs. Both parents share incubation and feeding duties until the chicks are ready to fledge, usually within a month's time.
Conservation Status
Though still relatively common across their range, the Dollarbird populations in Nepal are experiencing some threats because of habitat loss caused by deforestation. Community-driven forest conservation initiatives are currently attempting to create a balance between development activities and preserving Nepal's valuable ecosystems.
In conclusion, the Dollarbird is just one of many intriguing species found in the natural landscapes of Nepal. Their enchanting colors, agile flight, and unique behavior make them an ideal subject for wildlife enthusiasts and birdwatchers visiting this captivating country. Whether you're an amateur naturalist or simply seeking to learn more about Nepal's fascinating birds, the Dollarbird is undoubtedly a symbol of the area's stunning biodiversity that shouldn't be missed.
