Handbook of the Birds of the World, Volume 13: Penduline Tits to Shrikes

"[...] For keen world birders, this is a very important volume to possess since it includes illustrations of all the white-eyes (98 species), a group that includes many similar taxa, as well as those of another large (mainly Australasian) family the honeyeaters (175 species): neither of these groups have been covered elsewhere in any recent monograph. And whilst some readers may have the impression that white-eyes are relatively uninteresting or boring, a quick glance at Plate 36 may change your mind. It is a diverse group of birds with some stunningly plumaged species! HBW is undoubtedly one of the most important references for any keen birder or ornithologist to own, and I for one look forward to the last three of the 16 volumes. When Volume 16 is published in late 2011, it will complete the first work to describe and portray each species of any entire Class of the Animal Kingdom (with the obvious exception of some of those species that have been described during the publication period)."

"The series has developed into an immense and an immensely valuable resource, as well as one that has a unique aesthetic."
