The Sparrows A study of the genus Passer

Calton: T & A D Poyser, 1988. First edition, 1988. Hardback. 342pp. Dust jacket. Dr Summers-Smith's absorbing monograph is concerned with the world's twenty species of True Sparrows, the genus Passer. An international authority on the sparrows, his earlier monograph, "The House Sparrow", appeared in the Collins New Naturalist Series. The twenty species accounts include physical characteristics, distribution, breeding biology, feeding and other aspects of biology and behaviour in a common format that aids comparison and speculation as to the evolution of the genus. Important additional chapters discuss sparrow characteristics and relationships, their evolution and systematic position. Robert Gillmor provides eight superb colour plates illustrating all the species and a further 62 of his drawings grace the book's pages. In addition there are over 100 maps and diagrams. Book in near fine condition. Dust jacket very good and unclipped.
