The Correspondence of Charles Darwin: Volume 5, 1851-1855


Book Description

"For the first time full authoritative texts of Darwin's are made available, edited according to modern textual editorial principles and practice. Letter-writing was of crucial importance to Darwin's work, not only because his poor health isolated him from direct personal communication with his scientific colleagues but also because the nature of his investigations required communication with naturalists in many fields and in all quarters of the globe. Thus the letters are a mine of information about the work in progress of a creative genius who produced an intellectual revolution." --




Cuckoos of the World


Book Description

WINNER OF THE BIRDWATCH BOOK OF THE YEAR 2012 This authoritative handbook, part of the Helm Identification Guides series, looks in detail at the world's cuckoos, couas and anis - it is the ultimate reference to the cuckoos of the world. Famed as brood-parasites of other birds, the cuckoos include a diverse range of species, from the roadrunners of North America to the spectacular malkohas of southern Asia. This book discusses the biology and identification of these birds on a species-by-species basis, bringing together the very latest research with accurate range maps, more than 600 stunning colour photographs that illuminate age and racial plumage differences, and 36 superb plates by a team of internationally renowned artists.
