This book is the result of the research of 7 years by the author on avian fauna and rhesus monkey of Bir Bara Ban Sanctuary of Jind, Haryana ,India. The study concerns with wild fauna with more emphasis on Rhesus monkey (Macaca mulatta) and avian fauna of Bir Bara Ban Sanctuary in Jind district of Haryana state of India. Investigations concerning troop size, number, home range and the social behavior of Rhesus monkey (Macaca mulatta ) and presence of bird fauna and their diversity are likely to give interesting information. I believe that this book would be of immense help to the students as well as researchers of wildlife. It will add to the knowledge of general public regarding these denizens of nature.
