Blackeyed Bulbul (Darkcapped Bulbul)

I painted this referencing a photo by that you can see here:

This species is known as the Blackeyed Bulbul in South Africa, but elsewhere also as the Darkcapped Bulbul. It is sometimes considered a subspecies of the Common Bulbul, Pycnonotus barbatus, or sometimes a separate species, Pycnonotus tricolor. They are common, lively birds in the bush as well as in gardens, with cheerful calls. In Afrikaans we call it a 'Tiptol', or a 'Pietkluitjiekorrel' - the last is an onomatopoeic name based on its call. We also call it a 'Bottergat' ('Butter-butt') because of its yellow undertail feathers! Watercolour.
