| re-occupancy of breeding territories by ferruginous hawks in wyoming: relationships to environmental and anthropogenic factors. | grassland and shrubland birds are declining globally due in part to anthropogenic habitat modification. because population performance of these species is also influenced by non-anthropogenic factors, it is important to incorporate all relevant ecological drivers into demographic models. we used design-based sampling and occupancy models to test relationships of environmental factors that influence raptor demographics with re-occupancy of breeding territories by ferruginous hawks (buteo regalis) ... | 2016 | 27049324 |
