The Red-whiskered Bulbul was one of the many species originally described by Carl Linnaeus in 1758 in his Systema Naturae. He placed it along with the shrikes under Lanius.

The populations found across their range show a range of plumage variations and some of these are recognized as subspecies:
 jocosus, the nominate form is found in Hong Kong
 fuscicaudatus of peninsular India has nearly complete breast band and no white tip to tail
 abuensis of northwestern India (type locality Mount Abu) is pale and has a broken breast band and no white tip to tail
 pyrrhotis of the terai is pale above with white tail tips and widely separated breast band
 emeria of Eastern peninsula and Ganges Delta is warm brown above with a slim bill and a long crest (also introduced into Florida)
 whistleri is found in the Andaman Islands and has a warm brown above, a heavier bill and a shorter crest than emeria
 monticola is found in northeastern India and has darker upperparts than pyrrhotis
 pattani is found in Thailand
 peguensis not always recognized was described from southern Burma

বিৱৰণ
The Red-whiskered Bulbul is about  in length. It has brown upper-parts and whitish underparts with buff flanks and a dark spur running onto the breast at shoulder level. It has a tall pointed black crest, red face patch and thin black moustachial line. The tail is long and brown with white terminal feather tips, but the vent area is red.

The loud and evocative call is a sharp kink-a-joo (also transcribed as pettigrew or kick-pettigrew or pleased to meet you) and the song is a scolding chatter. It is more often heard than seen, but will often perch conspicuously especially in the mornings when they call from the tops of trees. The life span is about 11 years.

বিতৰণ
It has established itself in Australia, Los Angeles, Hawaii, and Florida in the United States, and in the Mauritius, Assumption Island and Mascarene Islands. In Florida, it is only found in a small area, and its population could be extirpated easily. 
বাসস্থান
This is a bird of lightly wooded areas, more open country with bushes and shrubs, and farmland. Irruptions have been noted from early times with Thomas C. Jerdon noting that they "periodically visiting Madras and other wooded towns in large flocks."

The Red-whiskered Bulbul feeds on fruits (including those of Thevetia peruviana that are toxic to mammals), nectar and insects.
প্ৰজনন
The breeding season is spread out and peaks from December to May in southern India and March to October in northern India. Breeding may occur once or twice a year. The courtship display of the male involves head bowing, spreading the tail and drooping wings. The nest is cup-shaped, and is built on bushes, thatched walls or small trees. It is woven of fine twigs, roots, and grasses, and embellished with large objects such as bark strips, paper, or plastic bags. Clutches typically contain two to three eggs. 

They defend territories of about  during the breeding season. They roost communally in loose groups of hundred or more birds.

মানুহৰ সৈতে সম্পৰ্ক 
This species was once a popular cagebird in parts of India. C. W. Smith noted that 
These birds are in great request among the natives, being of a fearless disposition, and easily reclaimed. They are taught to sit on the hand, and numbers may thus be seen in any Indian bazaar.

The species continues to be a popular cagebird in parts of Southeast Asia.
