Measuring Multiple Demographic Rates In Two Populations Of Northern Bobwhite, Alexander L. Jackson, D. Clay Sisson, Justin A. Rectenwald
National Quail Symposium Proceedings
Demographic rates of northern bobwhite (Colinus virginianus; hereafter, bobwhite) may vary spatially and temporally, and understanding the significance of these individual rates to population performance is critically important to bobwhite management. We present descriptive evidence from 2 populations that were simultaneously monitored from 2015–2020 that suggests different demographic rates can be more important to population performance than other demographic rates within the same region. Our objective was to understand the relative importance of various demographic rates to population performance in separate and seemingly stable populations. We monitored bobwhite seasonal survival and reproductive demographics on 2,475 bobwhites via radio-telemetry …

Florida Sandhill Crane Relocates Egg During Incubation, Timothy A. Dellinger, Miranda L. Watford, Ronald R. Bielefeld
Proceedings of the North American Crane Workshop
Anecdotal accounts of birds moving their eggs to a new location have been reported in shorebirds, waterfowl, and woodpeckers. We report relocation of an egg, 2 days prior to hatching, by an adult Florida sandhill crane (Grus canadensis pratensis). We do not know why the egg was moved, but egg movement among other species appears to be associated with nest disturbance by humans, animals, or environmental conditions.
