Data presented are results of surveys in 2021 for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. Surveys were conducted at 378 plots. Plots were surveyed twice in 2021 and the number, age (adult or juvenile), banding status (color banded or not), and breeding status (paired, unpaired, or unknown) of all wrens recorded. Habitat covariate data were collected including amount of dead and stressed cactus in the plot, percent cover of bare ground, and the dominant and percent cover of invasive species.

Data presented are results of surveys (2015) and monitoring (2015 and 2016) for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. Surveys were conducted at 35 plots. Plots were surveyed twice in 2015 and the number, age (adult or juvenile), banding status (color banded or not), breeding status (paired, unpaired, or unknown), and nesting status (active nest detected or not) of all wrens recorded. Habitat covariate data were collected including amount of dead and stressed cactus in the plot, percent cover of bare ground, and the dominant and percent cover of invasive species. During weekly monitoring visits, nests were located and checked to determine the number of eggs laid, the...

We used a stratified-random sampling approach to estimate the total abundance of Wedge-tailed Shearwater (Ardenna pacifica) nest sites across Kīlauea Point National Wildlife Refuge (KPNWR), Kauaʻi, during 1-7 July 2019. We first identified strata as unique geographic areas of the refuge to account for potential differences in nesting habitat and non-uniform nest site clustering. We then sub-divided strata where we expected high, low, minimal, or no nest site abundance. These distinctions were based on knowledge of shearwater nesting distribution gained while performing extensive ground-searching for tropicbirds across the entire refuge in April and May 2019. We delineated strata boundaries using recent satellite...

During 8-11 April, 13-18 May, and 1-7 July 2019, we censused Red-tailed (Phaethon rubricauda) and White-tailed (P. lepturus) tropicbird nests in Kīlauea Point National Wildlife Refuge (KPNWR), Kauaʻi, by searching all foot-accessible areas and by searching all cliffs and islets with spotting scopes from remote vantage points. We censused over the course of three visits to account for prolonged and asynchronous nesting. For ground searching, we used previous nest census results, recommendations from the previous Refuge biologist, and our knowledge of tropicbird nesting habitat, to focus searches in areas where nesting was likely: along cliff edges and steep slopes, particularly at the base of ironwood trees (Casuarina...
