Critically Endangered mammals and birds

The general distribution of almost all the 362 mammal and bird species categorised as Critically Endangered, the highest risk category, in 2000. Each circle represents one distribution record; some species are known from a single point locality, others are represented by a cluster of localities. On this map, a high density of symbols can represent many records of a single species, or single records of many separate species. Red and blue symbols represent mammals and birds, respectively.
