Alaska goose populations: Past, present and future
James G. King, Dirk V. Derksen
1986, Conference Paper, Transactions of the fifty-first North American wildlife and natural resources conference
Many people think Alaska remains a pristine wilderness and that wildlife populations are still at prehistoric levels. This very likely is not true for the 11 species and subspecies of geese that nest in Alaska. Large, widely dispersed populations of geese were observed near the turn of the century. Even...
What won't Turnstones eat?
Robert E. Gill Jr.
1986, British Birds (79) 402-403
The Turnstone Arenaria interpres probably has one of the most varied diets of any wader species. Besides the 'normal' foods taken (see, e.g., Prater 1972, Nettleship 1973, Jones 1975), a considerable variety of 'unusual' foods and feeding behaviours has also been reported. Items taken include soap, gull excrement, dog food,...
