Waders of the Indian Subcontinent by Harkirat Singh Sangha is an invaluable reference book for birders as it contains detailed descriptions of all 83 wader species of the region, both resident and migratory.

The author has been kind enough to credit me in the acknowledgements section of his book.

I hope Waders of the Indian Subcontinent does well because it is probably the most comprehensive modern book on the topic. Previously only books published for sportsmen (as hunters were termed in those days) during the British Raj were available for reference.
