ex1027

Data are measurements on breeding pairs of land-bird species collected
 from 16 islands around Britain over the course of several decades.
 For each species, the data set contains an average time of extinction
 on those islands where it appeared, the average number of nesting
 pairs, the size of the species and the migratory status of the
 species.
