RED-VENTED BULBUL, Pycnonotus Cafer (Linnaeus).  I photographed this bird at the Chintamani Kar Bird Sanctuary, Kolkata’s Little Secret. You can see it’s website at:  http://www.kolkatabirds.com/ckbs.htm  I identified it with several books including From “The Book of Indian Birds Salim Ali and “A Photographic Guide to Birds of Bangladesh” by Ronald R. Halder.  One of my friends is a friend of Ron, and has at least one photo in Harder’s book.  The book by Halder I have is actually an autographed copy I borrowed from a friend.
