Kype and/or characteristics that could be of importance in inter- and intra-sexual evaluations of individual quality. The size of the kype is believed to determine male spawning frequency. The extinct sabertooth salmon, "Oncorhynchus rastrosus", was first named for its prominent premaxillary dentition. It possesses an enormous conical tooth on each premaxilla. There is no visible kype on the dentary, implying a different strategy for forming mate dominance.

The EBCC Atlas of European Breeding Birds subdivision are shown. The book concludes with sections on the Conservation Status of Europe's Birds, a list of species with threat statuses, a set of derived maps depicting overall species richness and richness of threatened species, and a 65-page references section. The book's dustjacket is illustrated by bird artist David Nurney - the front cover shows a common kingfisher (with a map of its distribution), while a European bee-eater is depicted on the spine. The European Ornithological Atlas project was initiated in 1971. Its fieldwork took the form of surveys during the breeding season, in each of the countries within
