Taxonomy
The bulbuls are a widespread family of songbirds, found much over Africa and Asia.
The Common Bulbul has a number of subspecies; some authorities consider P. b. dodsoni (Dodson’s Bulbul), P. b. somaliensis (Somali Bulbul) and P. b. tricolor (Dark-capped Bulbul) as separate species from the nominate P. b. barbatus.
