HUMMING-BIRDS. 
are inhabitants of the higher Andes from Ecuador to Chili, each species having a 
peculiar and restricted range. Thus, 0. pichincha and 0. chimborazo occur only in 
Ecuador, the former being confined to the volcanoes of Pichincha and Cotopaxi, and 
the latter to that of Chimborazo ; 0. adelcc lives on the Andes ofc* Bolivia, 0. leuco- 
pleuru.s on those of Chili, while 0. melanogaster and 0. estellce inhabit the Andes 
of Peru, the latter also occurring on those of Bolivia. The Cliimborazan species, of

abdomen, and the Cliimborazan species differs from its ally only in having the

must be a bird which presents many curious features in its economy, if any
