Lesser and greater prairie-chickens (Tympanuchus cupido
) have already been shown to exhibit avoidance behavior of anthropogenic features such as power lines (Hagen et al, 2011) and wind turbines (Winder et al, 2014a); therefore, if avoidance has already occurred, detection of an effect on survival may be difficult.
Instead, Fran laid the foundation for the field of raptor research and her work with prairie chickens led the conservation efforts that prevented the extinction of the greater prairie chicken (Tympanuchus cupido
) in Wisconsin.
Geological Survey, C2S2 provides advice and guidance for improved captive management of the federally endangered masked bobwhite quail (Colinus virginianus ridgwayi) at Buenos Aires National Wildlife Refuge in Arizona; is assessing the causes of death in reintroduced Attwater's prairie chickens (Tympanuchus cupido
attwateri) at Attwater's Prairie Chicken National Wildlife Refuge in Texas; and is examining the low fertility of the whooping crane breeding flock at the Patuxent Wildlife Research Center in Maryland.
Invasion by shrubs has been cited as a possible cause for declines in populations of Attwater's prairie-chicken (Tympanuchus cupido
attwateri) and lesser prairie-chickens (New Mexico Department of Game and Fish, in litt.).
PRSNA is managed by the Illinois Department of Natural Resources (IDNR) primarily as habitat for the greater prairie chicken (Tympanuchus cupido
), a state endangered species.
Today, the greater prairie-chicken (Tympanuchus cupido
) exists only in small pockets on a fraction of its historic range.
Species of concern, such as the greater prairie-chicken (Tympanuchus cupido
), Henslow's sparrow (Ammodramus benslowii), dickcissel (Spiza americana), regal fritillary butterfly (Speyeria idalia), and prairie mole cricket (Gryllotalpa major) also reside on post.
To illustrate, we applied LSA to vital rates for two vertebrates: desert tortoise (Gopherus agassizii) and Greater Prairie Chicken (Tympanuchus cupido
Wilson and Silvy (1988) included a number of observations of predation on individual birds, including Attwater's prairie chicken (Tympanuchus cupido
attwateri), northern bobwhite (Colinus virginianus), and scissor-tailed flycatcher (Muscivora forficata).
