Kus 2022 publication Open-File Report 2022-1044 n/a U.S. Geological Survey https://doi.org/10.3133/ofr20221044 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 number of eggs that hatched, and the number of chicks that fledged. Nesting data were compiled to present seasonal productivity for each Cactus Wren pair. All nestlings and adults (when possible) were color banded with unique color combinations to identify individuals on subsequent visits to provide data on survival within and between years. During banding, data were collected on age, sex, weight, and reproductive status. Fecal samples were collected from nestlings when possible. In each territory, a 75 x 75 m grid of 30 points was placed to include as many nests as possible. At each point, data were collected within a 2 m radius circle including presence or absence of native bunch grasses, non-native annual grasses, cactus, elderberry (Sambucus nigra), lemonadeberry (Rhus integrifolia), sagebrush (Artemisia californica), buckwheat (Eriogonum fasciculatum), black mustard (Brassica nigra), and bare ground. These presence/absence data were summarized to present the percent cover of each species or ground cover representing habitat at the Cactus Wren territory. The two goals for collecting these data were to assess Cactus Wren population status following the 2014 drought and to monitor execution of SANDAG’s Implementation Plan’s highest priority management actions including determining the relationships between specific elements of habitat quality, food availability, and Cactus Wren breeding productivity and survival, and using this to refine management actions to increase population abundance and resilience. 20150318 20160831 ground condition In work Annually -117.100692 -116.818594 32.867009 32.552763 San Diego County ISO 19115 Topic Category biota USGS Thesaurus birds habitats vocalization methods animal and plant census None survey monitoring productivity survival drought USGS Metadata Identifier USGS:6305498ed34ed6dc55934099 None San Diego California None.

SanGIS 2013 Shapefile \\BLACK-XP\E$\Monthly Updates\Parcels.shp 24000 online Unknown ground condidtion Owner The land owner information from this layer was used to define [Owner] for table [Cactus Wren Plot Location Information] - Survey Methods: • After arriving at the survey plot, stand quietly for 1-2 minutes listening for wren vocalizations. • If no wrens are detected, play the Cactus Wren vocalization for 30-40 seconds, at intervals of at least 1 minute of silence in between broadcasts. • At each location, broadcasts shall be discontinued once a wren is detected. • Total survey time during which vocalizations are broadcast shall not exceed 10 minutes. Total time spent collecting information when Cactus Wren(s) present should not exceed 30 minutes. • Attempt to re-sight all Cactus Wrens to determine banding status and read color band combinations. • Attempt to determine breeding status by identifying pairs, dependent fledglings, or active nests. • Do not approach nests or broadcast vocalizations if you detect Western Scrub-jay, Common Raven, American Crow, Greater Roadrunner, Sharp-shinned Hawk, Cooper’s Hawk, or other nest predators (snakes, etc.) in the immediate vicinity. - Nest Monitoring • Cactus Wrens are detected during a survey in February-March in an area where nest monitoring is proposed. • Monitors return to the area within the week to determine breeding status and search for nests. • Breeding status is determined by detecting the presence of pairs, or spending sufficient time (up to 1 hour) in the territory and only detecting a single bird (unpaired). • Nests are located by watching adults fly with nest material to football-shaped, domed collections of twigs and grasses within cholla or prickly pear cactus, or by scanning the area with binoculars and visually identifying nests. • When a nest is identified, monitors wait for Cactus Wrens to leave the vicinity of the nest, then monitors approach and check for nest contents using a fiber-optic camera or carefully feeling inside the nest by hand. Location of the nest is marked using GPS and contents/status of the nest is recorded. • Multiple dummy or roost nests are usually present within a Cactus Wren territory. These can be distinguished from brood nests by their lack of thick, soft lining and by their small size and compact shape. Brood nests are generally deep (have a long entrance tunnel that dips down into the brood chamber) while roost nests tend to be shallow with a short entrance, the roost chamber at the same level as the entrance tunnel. • If the new nest appears to be an empty brood nest, or has eggs and/or nestlings, monitors return and check the nest weekly to monitor its progress. • If the new nest appears to be a roost nest, monitors continue looking for active brood nests, but check the roost nest on subsequent visits in case it is modified by the wrens to be used as a brood nest. • Monitors schedule a visit to the nest for when nestlings are 7-12 days old, when each nestling is given a unique combination of colored leg bands and a fecal sample is collected, if possible. • Nests are deemed successful if at least one fledgling is seen (or heard begging) out of the nest, seen roosting in the nest after 23 days of age, or the nest was still active at 19 days of age but no indication of depredation was observed afterwards. • Nests are deemed unsuccessful if all eggs or nestlings disappeared between nest checks and nestlings were not old enough to fledge (19 days). - Data Collection • Develop data collection table for Juno Trimble units, using ArcMobile: February 2015 • Collect data digitally: March-August 2015, March-August 2016 • Proof and compile data in lab SQL Server relational database and ancillary MS Excel spreadsheets: September-November 2015, September-October 2016 • Finalize Excel spreadsheets in tabular presentation form: November 2015, October 2016 • Finalize shapefiles and export to geodatabase: October 2016 • Import Excel tables, format, and link to geodatabase shapefiles: October 2016 • As opportunity permits, monitors target-net unbanded adults using 35mm mesh mist-nets and broadcast Cactus Wren calls. Captured adults get a unique combination of colored leg bands.
