Ever since the general acceptance of the theory that Bering Strait served as the entrance of man into North America, Alaska has been suggested as the most likely area for additional discoveries adding to our knowledge of Early Man. In spite of the fact that the bulk of these discoveries has occurred in the Southwest or in the far west of the United States proper, increasing attention has been paid to northern regions. The Folsom and also the Yuma problem (or problems as the case might be) have been traced into the northern Plains regions of Saskatchewan, Canada.

American White Pelican

At nesting colonies of American White Pelicans (Pelecanus erythrorhynchos), many chicks die from siblicide, severe weather, and disease; this results in carcasses available for scavenging by conspecifics (i.e., indirect cannibalism). Indirect cannibalism has not been reported previously for this species. We describe five cases of crèche-aged American White Pelican chicks consuming or attempting to consume dead younger chicks at two nesting colonies in the northern plains of North America. Cannibalism in the American White Pelican appears to be rare and likely plays no role in the species’ population ecology or dynamics; however, it might be an important survival strategy of individual chicks when food resources are limited.
