Helm Identification Guides

This detailed and comprehensive identification guide follows in the mould of Sylvia Warblers and Pipits and Wagtails. It primarily covers the genera Acrocephalus, Locustella, Cettia and Bradypterus,
together with a few smaller related genera. To the uninitiated, these
are the archetypal ''little brown jobs'' and as if they weren''t hard
enough to identify anyway, many of them are hard to see as well! This
authoritative handbook covers their identification in breathtaking
detail, illustrated with line drawings, sonograms, wonderful colour
plates and photographs. It is destined to become the ultimate reference
for these challenging birds.
