Though not strictly a bird book, I have a copy of Wood's New Illustrated Natural History which has a bird section in it, including articles and etched drawings of Passenger Pigeons and Ivory Billed Woodpeckers. It is a third addition,printed in 1885.
Also have an 1899 copy of British Birds' Eggs and Nests by Revd J.C.Atkinson and an circa 1875 copy of Gilbert White's Natural History of Selbourne.
All these fascinating books once belonged to my grandfather who introduced me to the wonderful world of nature when I was a wee lad.
