Habitat loss and degradation by invasive species is a primary limitation to the recovery of the Western Snowy Plover (Charadrius nivosus nivosus), a federally threatened shorebird that resides on coastal beaches in Humboldt County, California. This habitat threat posed by European Beachgrass (Ammophila arenaria) is often mitigated through dune restoration. Some habitat features altered by restoration (e.g., beach width) may influence plover breeding habitat selection. Further study was needed to determine which physical and social features (e.g., presence of conspecifics) influence plover nesting locations. I evaluated this response of plovers to restoration and identified characteristics that influence nest site selection. In an Information-Theoretic framework, I compared nests (n = 81) and random locations within habitat using logistic regression and Generalized Linear Mixed Models to produce Resource Selection Function analyses and conduct model selection analyses. Plovers nested on wider, less sloped beaches, with greater coverage of natural debris (e.g., driftwood, shells) and more conspecifics than at random locations. Plovers nested primarily (84%) in restored habitats, although this was influenced by one human-restored site with 33% of nests. These findings can guide coastal dune system managers to generate the features in restoration that improve nesting habitat and facilitate survival and recovery of this threatened Snowy Plover population.

The 40 or so species of beach-loving plovers (genus Charadrius) comprise a diverse group of shorebirds found around the world. Most of these species are challenged by changing climates and other human-related development activities, yet they provide key insights into basic ecological and evolutionary processes. The expert international contributors take a comparative approach, presenting examples from many worldwide plover studies and synthesizing the group’s most pressing and important topics. The book further presents an emphasis on full life-cycle biology, including the importance of examining migratory connectivity issues, even for non-migratory plovers.

Between 1995 and 2004, the 25.7 hectare Guadalupe Oil Field supported up to 21 breeding pairs of snowy plovers each season. While mean hatching success (0.58) was slightly higher than at other breeding sites, success rates declined after 1998 with predation the dominant source (0.61) of nest failure.

ABSTRACT: To expand upon the current ecological knowledge of Snowy Plovers, I studied breeding Snowy Plovers nesting along the Florida panhandle during 2008-09. I contrasted four alternative hypotheses (prey availability, human activity, predator activity, and physical features of the habitat) and the influence each had on habitat selection and reproductive performance during both the nesting and brood-rearing stages of breeding. I modeled the probability of selection and the daily survival rates as a function of predictors representing each hypothesis by breeding stage (i.e., nesting, brood-rearing). Nest-site selection and daily nest survival were a function of all four hypotheses working in combination. In contrast, brood-site selection was a function of prey availability alone and daily brood survival was a function of prey availability, predator activity, and physical features combined. Collectively, this information will provide for habitat management that will benefit the Snowy Plover. Additionally, my results provide a unique demonstration of how multiple selective forces influence site selection and reproductive performance that is relevant to wildlife in general.

Variance in LRS was best explained by breeding substrate, with gravel breeding birds having significantly higher LRS compared to beach breeding birds. Models containing this covariate accounted for nearly 100% of the corrected-Akaike weights based on the relative importance of model covariates. Other measures of habitat quality, including measures of nest exclosures, corvid abundance and human activity, were not significant predictors of LRS. The results from this study provide valuable information regarding the relationship between LRS and habitat quality, and thus can be used to guide management aimed at increasing the reproductive success of this threatened species.

Understanding the social and physical factors that influence the temporal and spatial distribution of a species is imperative for successful management. The Western Snowy Plover (Charadrius nivosus nivosus) selects for wide-open stretches of beach; yet within large expanses of ideal habitat, plover populations tend to be aggregated. Recent evidence suggests plovers may prioritize social information over ideal physical factors alone when selecting breeding locations. I analyzed data collected on an individually marked population of Snowy Plovers in Humboldt County, California from 2001 to 2018 to evaluate the influence of physical (beach width) and social (presence of conspecifics) landscape factors on the population’s breeding distribution. Using an information-theoretic framework, I conducted incidence function models and model selection analyses to examine how physical and social factors influenced inexperienced breeder occupancy of approximately 100 km of plover habitat. Beach width influenced where plovers bred, however, inexperienced plovers were more likely to colonize sites occupied by experienced conspecifics. Reproductive success had minimal influence on settlement of inexperienced breeders the following season. This information suggests the species’ successful recovery requires an added emphasis on social information for future habitat restoration efforts.
