Patterns Of Bison Hair Use In Nests Of Tallgrass Prairie Birds, Bryan R. Coppedge
Patterns Of Bison Hair Use In Nests Of Tallgrass Prairie Birds, Bryan R. Coppedge
The Prairie Naturalist
I examined patterns of bison (Bison bison L.) hair use by passerine birds nesting in the Tallgrass Prairie Preserve, Osage County, Oklahoma, 2002-2004. I collected and dissected 103 nests of 15 species into their constituent components. Nests were predominately composed of herbaceous material such as grass stems and leaves. Woody material and mud were rarely used. Bison hair was the most prominent zoological material used in nests, with lesser amounts and occurrence of arthropod silk, snake skin, feathers, jack rabbit (Lepus californicus Oray) fur, and man-made materials such as cellophane and string. At least one nest of 13 …
Wolf, Canis Lupus, Visits To White-Tailed Deer, Odocoileus Virginianus, Summer Ranges: Optimal Foraging?, Dominic J. Demma, L. David Mech
Wolf, Canis Lupus, Visits To White-Tailed Deer, Odocoileus Virginianus, Summer Ranges: Optimal Foraging?, Dominic J. Demma, L. David Mech
USGS Northern Prairie Wildlife Research Center
We tested whether Wolf (Canis lupus) visits to individual female White-tailed Deer (Odocoileus virginianus) summer ranges during 2003 and 2004 in northeastern Minnesota were in accord with optimal-foraging theory. Using GPS collars with 10- to 30-minute location attempts on four Wolves and five female deer, plus eleven VHF-collared female deer in the Wolves’ territory, provided new insights into the frequency of Wolf visits to summer ranges of female deer. Wolves made a mean 0.055 visits/day to summer ranges of deer three years and older, significantly more than their 0.032 mean visits/day to ranges of two-year-old deer, …
