The Crimson sunbird is a delightful sight commonly found in gardens as it gracefully moves from one flower to another. Its brightly-colored red feathers, accompanied by an iridescent blue cap and a distinct “mustache”, make it a standout among other birds.
The Aethopyga siparaja, commonly known as the crimson sunbird, is a type of bird belonging to the sunbird family. It has a slender bill that curves downwards and is of medium length. The tip of its tongue is brush-tipped and tubular in shape, which helps it feed on nectar. The adult male crimson sunbird has a striking appearance, with a bright red throat, chest, and flanks. It also has distinct mustache-like stripes that are deep blue in color. The bird’s back is maroon-colored, its rump is yellow, and its abdomen is olive-colored. Its look is complete with a blue-green tail that has white tips on the outer feathers.
When it comes to appearance, the adult female is less vibrant than her male counterpart. Her back is more of an olive-green shade while her chest has a yellowish hue. Additionally, the tips of her outer tail feathers are white.
The stunning crimson sunbird can be found in various tropical regions of southern Asia. This bird is a permanent resident and breeds in countries such as India, Nepal, Bangladesh, Myanmar, Indonesia, and Brunei Darussalam.
The preferred diet of crimson sunbirds is nectar, but they also supplement their protein intake with insects during the breeding season to nourish their offspring and themselves.
Male and female crimson sunbirds work together to construct a charming nest that is covered in moss and shaped like a purse. While the female takes care of lining the nest, the two birds usually hang it from the underside of big fern fronds or thin branches of a ɩow tree or shrub. After the nest is ready, the female lays an average of three eggs, which take about 18 to 19 days to hatch. The male also pitches in by helping to feed the offspring.
The Crimson Sunbird is not considered to be in danger as they have a vast range and a stable population.
