From the introduction:
"The Cattle Egret, Bubulcus ibis (L.) is a polytypic species having three subspecies. Nominate subspecies, Bubulcus ibis ibis (L.) is found in Africa, Madagascar, South Europe, South America and North America. Subspecies B.i. coromandus (Boddaert), commonly known as the Asiatic subspecies, occurs in Pakistan, India, and other countries of the Orient, and in Australia. The third subspecies, B.i. seychellarum (Salomonsen) is found on the islands of the Seychelles. Out of the three subspecies, adequate information on the biology of B.i. ibis is available. Exiguous studies have been carried out on the other two subspecies, with the result that the information on these subspecies remains meagre.
In this monograph three major aspects of biology, viz. breeding biology, feeding ecology, and population density of the Asiatic subspecies, B.i. coromandus, are covered."
