On Two Fronts: Occurrence of the House Sparrow in Alaska
Daniel D. Gibson
ABSTRACT: The first Alaska records of the House Sparrow (Passer domesticus), comprising birds reaching southeastern (132° W) and far western (171° W) localities in the state, probably reflect short-distance dispersals from adjacent Canada (British Columbia) and from the adjacent Russian Far East (Chukotka), respectively. Both source populations are the results of human introductions.
