Reliability of Occupancy and Binomial Mixture Models for Estimating Abundance of Golden-cheeked Warblers (setophaga Chrysoparia)
—Reliable estimates of population parameters derived from survey methods are essential for decision making in management of endangered species. We evaluated whether point-count surveys used in conjunction with occupancy and binomial mixture models (BMMs) constituted a reliable approach for monitoring the federally endangered Golden-cheeked Warbler (Setophaga chrysoparia) on a preserve in centra...
متن کاملAge-specific survival of male Golden-cheeked Warblers on the Fort Hood Military Reservation, Texas
Population models are essential components of large-scale conservation and management plans for the federally endangered Golden-cheeked Warbler (Setophaga chrysoparia; hereafter GCWA). However, existing models are based on vital rate estimates calculated using relatively small data sets that are now more than a decade old. We estimated more current, precise adult and juvenile apparent survival ...
متن کاملPresence–nonpresence surveys of golden-cheeked warblers: detection, occupancy and survey effort
Surveys to detect the presence or absence of endangered species may not consistently cover an area, account for imperfect detection or consider that detection and species presence at sample units may change within a survey season. We evaluated a detection–nondetection survey method for the federally endangered golden-cheeked warbler (GCWA) Dendroica chrysoparia. Three study areas were selected ...
متن کاملDifferences in Song Rate in Two Populations of Yellow Warblers
—The Yellow Warbler (Dendroica petechia) has a mating system characterized by monogamy and biparental care, and has the broadest breeding distribution of any Dendroica species. When faced with a short breeding season and unpredictable conditions at high latitude, they display physiological responses to help optimize the tradeoff between individual risk and reproductive success. Because these ci...
متن کاملSpatiotemporal variation in range-wide Golden-cheeked Warbler breeding habitat
Habitat availability ultimately limits the distribution and abundance of wildlife species. Consequently, it is paramount to identify where wildlife habitat is and understand how it changes over time in order to implement large-scale wildlife conservation plans. Yet, no work has quantified the degree of change in range-wide breeding habitat for the Golden-cheeked Warbler (Setophaga chrysoparia),...
