Illustration of a purple-rumped sunbird (Leptocoma zeylonica, here as Nectarinia zeylonica), a sunbird endemic to the Indian Subcontinent. Like other sunbirds, they are small in size, feeding mainly on nectar but sometimes take insects, particularly when feeding young. They can hover for short durations but usually perch to suck nectar from flowers. They build a hanging pouch nest made up of cobwebs, lichens and plant material. Males are brightly coloured but females are olive above and yellow to buff below. Males are easily distinguished from the purple sunbird by the light coloured underside while females can be told apart by their whitish throats. 18th century watercolor painting by Lady Elizabeth Symonds Gwillim (1763-1807). Lady Gwillim painted a series of about 200 watercolours of Indian birds. Produced about 20 years before John James Audubon, her work has been acclaimed for its accuracy and natural postures as they were drawn from observations of the birds in life.
