The red-vented bulbul (Pycnonotus cafer) has red under-tail coverts which give it its name. A resident breeder across the Indian subcontinent, it is native from Pakistan to China - but it has been introduced in many other parts of the world and has established itself in the wild on several pacific islands including Fiji, Samoa, Tonga, and Hawaii. It is considered an agricultural pest because it damages fruit crops.
