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.

This part of the Oregon OCS data release presents marine mammal observations from cruise 2014-607-FA in the Floating Wind Farm survey area. The survey was conducted using 12 hour day operations out of Charleston Harbor near Coos Bay, Oregon. The cruise plan consisted of 23 days on site split between sonar mapping and video ground truth surveying. Activities parsed out to nine days of sonar mapping, three days of video surveying, eight days of no operations due to weather, and three days mobilizing and demobilizing (table 1). Typically the Snavely would transit out to the survey area in an hour at a speed of 20 knots. Marine Mammal observations were made during the multibeam sonar mapping portion of the cruise only....

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 13-18 May, 2019, we censused red-footed boobies (Sula sula) at Kīlauea Point National Wildlife Refuge (KPNWR), Kauaʻi. To evaluate ground-based visual counts and assess variability among methods, we employed photographic techniques to count nesting red-footed boobies at KPNWR in three distinct sub-colony areas: Crater Hill East, Crater Hill Interior, and Crater Hill West (see associated data series report for delineation of sub-colony areas). For ground-based photos, we used a Sony a7rii camera (42 megapixel full-frame) equipped with a Sony 100-400mm F4.5-5.6G lens to allow sufficient resolution to count nests and birds. We achieved pixel resolutions (as a function of camera resolution, focal length, and...

Data presented are results of surveys and monitoring in 2017 for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. Surveys were conducted at 362 plots. Plots were surveyed twice in 2017 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 8-11 April, 13-18 May, and 1-7 July 2019, we censused Red-tailed Tropicbird (Phaethon rubricauda) and White-tailed Tropicbird (P. lepturus) 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 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...

The St. Clair River delta, part of the St. Clair-Detroit River System (SCDRS), is the most fished coastal wetland area in the Laurentian Great Lakes and provides nursery habitat for a variety of fish species; however, few large-scale surveys of early fish life stages have been performed since the 1980s. Larval fish, zooplankton, and aquatic plants were sampled at 21 sites in delta channels and backwaters of the St. Clair-Detroit River System (SCDRS; USA/CAN) from May to July in 2010 and 2011 to characterize the habitats and resources used by larval fish in the delta. Larval fish were captured using conical nets and light traps, and diets from larval white sucker (Catostomus commersonii) were collected at three sites.

We have incorporated the Hawaiian language spellings of place names however, software limitations for metadata files did not allow for inclusion of the appropriate diacritical markings. We took oblique aerial photographs of Lehua during the late morning of 13 May from a H-65 Dolphin helicopter with the door open to provide the best viewing conditions. During the late morning on 16 May 2019, we worked with U.S. Coast Guard Auxiliary on-board a Piper Saratoga fixed-wing aircraft (single-engine, low-wing) to photograph the Red-footed Booby colony in Ulupa'u Crater and the entire surface of Moku Manu taken through a tinted, rear Plexiglas window. We used a Canon 5DSr camera (51-megapixel full frame) equipped with a...

Data presented are results of surveys and monitoring for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. These data were collected to assess Cactus Wren population status to determine the relationships between specific elements of habitat quality and Cactus Wren presence. Surveys were conducted periodically at 507 plots throughout San Diego County. Birds that had been banded in prior years with unique color combinations were identified to individual on subsequent visits to provide data on survival and movement between years. These data support the following publication: Lynn, S., and Kus, B.E., 2023, Distribution and demography of coastal Cactus Wrens (Campylorhynchus brunneicapillus)...

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.

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, in 2019. To estimate stratum-specific nest site abundance, we generated randomly located, non-overlapping circular plots within several sampling strata. We set plot radius to 5 m in most strata, except for some portions of Kīlauea Point where a 3-m radius was used to accommodate narrow strips of habitat. We generated enough plots to survey 10 percent of total stratum area where we expected high nest site abundance, and 5 percent of stratum area where expected nest site abundance was low or minimal. This data table contains...
