Birds Of The Great Plains: Appendix A -- A Guide To Bird-Watching Localities In The Great Plains, Paul A. Johnsgard

Birds of the Great Plains (Revised Edition, 2009) by Paul Johnsgard

Partly on the basis of the availability of relatively complete bird lists available for the areas, I have included here forty-four state and federal parks, refuges, and other sanctuaries located within the region covered by this book. Nearly all the national wildlife refuges are included, except a number of smaller refuges for which bird lists are not available. Further, a group of four North Dakota national wildlife refuges in the Souris Valley is collectively considered in a "Souris Loop" category. In the discussion that follows and the associated list of summer birds, the localities are grouped by states, and the …

Birds Of The Rocky Mountains With Particular Reference To National Parks In The Northern Rocky Mountain Region, Paul A. Johnsgard Jan 2009

Birds Of The Rocky Mountains With Particular Reference To National Parks In The Northern Rocky Mountain Region, Paul A. Johnsgard

Birds of the Rocky Mountains by Paul A. Johnsgard

Notwithstanding the great latitudinal spread and the equally wide altitudinal variations that occur in the region, the Rocky Mountains contain surprisingly uniform bird life. A bird-watcher in Banff or Jasper national parks in Alberta will encounter the vast majority of the same breeding species in the coniferous zones of those areas as one who is observing nearly a thousand miles to the south in Rocky Mountain National Park, although particular bird species would occur at considerably different altitudes.

This comprehensive reference work describes in detail 354 species found in a 353,000-square-mile area—from the 40th parallel in Colorado north to the …

Cooperation And Competition: Nepotistic Tolerance And Intrasexual Aggression In Western Bluebird Winter Groups, Janis L. Dickinson, Melody Euaparadorn, Katherine Greenwald, Chandreyee Mitra, Daizaburo Shizuka Jan 2009

Cooperation And Competition: Nepotistic Tolerance And Intrasexual Aggression In Western Bluebird Winter Groups, Janis L. Dickinson, Melody Euaparadorn, Katherine Greenwald, Chandreyee Mitra, Daizaburo Shizuka

Papers in Ornithology

Two hypothesized benefits of delayed dispersal are access to resources and prolonged brood care (or parental nepotism). Resource abundance (mistletoe wealth) is a key factor influencing whether sons stay home in western bluebirds, Sialia mexicana, but nepotism is also observed. Western bluebird sons commonly remain in their family groups throughout the winter, whereas daughters usually disperse before winter. Because pairing often takes place in winter groups, with newly formed pairs settling on exclusive all-purpose territories in spring, selection for sexual competition and nepotism co-occur and may simultaneously influence patterns of aggression within groups. We measured aggression at mealworm feeder …
