An ongoing series of monographs on all aspects of natural history, but with a particularly good ornithological section, covering individual species, families or various avian topics. Written in German, each paperback volume is well illustrated, often in colour.
"[...] the German series Die Neue Brehm-Bücherei (is) one of the best natural history series, probably unique in coverage and quality, but largely neglected outside central Europe."
