July 30,Virginia Tech Virginia Tech doctoral student Katherina Gieder created a model to help managers protect the piping plover, a tiny shorebird that has been on the federal threatened list since Beach walkers along the East Coast often share the sand with several kinds of birds that scavenge the shore just out of the reach of waves. Among these shorebirds is the piping plover—a tiny, busy bird that nests in open areas along the beach. Its neighborhood preference has resulted in this once common shorebird being on the federal threatened species list since

In coastal areas with recreational activity, human disturbance may limit use of otherwise suitable habitat. Snowy plovers Charadrius nivosus have a patchy breeding distribution along the coastal areas on the Florida Panhandle, USA.
Our goal was to determine the relative effects of seasonal human disturbance and habitat requirements on snowy plover habitat use.
We surveyed sites for snowy plovers, human disturbance, and habitat features between January and July and We made multiple visits during three different sampling periods that corresponded to snowy plover breeding: Snowy plover site occupancy and colonization was negatively associated with human disturbance and site extinction was positively associated with human disturbance.
Interdune vegetation had a negative effect on occupancy and colonization, indicating that plovers were less likely to use areas with uniform, dense vegetation among dunes. Also, dune shape, beach debris, and access to low-energy foraging areas influenced site occupancy, colonization, and extinction.
Plovers used habitat based on beach characteristics that provided stage-specific resource needs; however, human disturbance was the strongest predictor of site occupancy. In addition, vegetation plantings used to enhance dune rehabilitation may negatively impact plover site occupancy.
Management actions that decrease human disturbance, such as symbolic fencing and signage, may increase the amount of breeding habitat available to snowy plovers on the Florida Panhandle and in other areas with high human activity. The specific areas that require this protection may vary across snowy plover life history stages.
Beach, coastal engineering, multi-season occupancy models, nesting, restoration, shorebird Introduction Habitat use has important consequences for avian reproductive success and survival Matessi and Bogliani ; Doligez et al. Birds should use breeding areas that maximize access to resources Sergio and Newton ; Preston and Rotenberry ; Crampton et al.
In seasonal and heterogeneous environments, habitat selection most likely occurs on several temporal and spatial scales Hutto and, for species with precocial young, habitat requirements of different breeding stages may contribute to the complexity of habitat use.
Understanding the factors that affect habitat use is important for management programs and restoration projects that attempt to provide habitat for declining species. In systems with seasonal changes in resources, or for species that utilize different habitats during different parts of the reproductive cycle, occupancy models that allow for movements within the breeding season may be useful Betts et al.
For example, Betts et al. The closure hypothesis was rejected for most species observed. These results indicate that for many avian species, habitat use is not static, and instead occupancy is likely to change throughout the breeding season.
The factors that cause birds to move among sites may not be obvious. Models that allow for site colonization transition from an unoccupied site to an occupied site and extinction transition from an occupied site to an unoccupied site have the potential to pinpoint spatial and temporal variations in the landscape that affect apparent movement MacKenzie et al.
For example, some ground-nesting shorebird species may attempt to minimize predation risk during incubation by choosing cryptic nesting areas with lower risk of predation Winton et al.
If chicks are precocial, adults may attempt to move them to foraging areas that will have high food availability during brood-rearing Cohen et al. In a species not bound to its nesting territory during the brood-rearing period, a multi-season occupancy model may provide more information about habitat use in each reproductive stage.
Snowy plovers Charadrius nivosus Fig. Snowy plovers are listed as threatened by the state of Florida Wood and Pacific coast populations are federally listed in the United States as threatened Federal Register Population declines and subsequent listings have been attributed to increased human development and recreational activities in the snowy plovers' breeding and wintering grounds Gore and Chase ; Federal Register Along the Florida Panhandle, snowy plovers are year-round residents and their annual cycle consists of wintering, pre-breeding territory establishmentnesting egg-laying and incubationand brood-rearing.
Pairs may nest again after a failure and pairs that successfully breed early in the season may make a second breeding attempt. Breeding snowy plovers have a patchy distribution along the Florida Panhandle Lott and suitable habitat may be limiting. Furthermore, human activities on Panhandle beaches change over the course of the plover breeding season, from relatively few visitors in the winter to thousands of beach goers during the spring and summer.
Increased human disturbance may cause plovers to fail or may limit access to suitable breeding areas Lafferty et al.Research on the Media Portrayal of Piping Plovers Now Available. A new social science research paper on the media portrayal of piping plovers and their conservation on the Atlantic Coast of the US is now available from the journal “Oryx”.
The Piping Plover Unit combines Science (Interactions) and Social Studies (Biomes) curriculum guidelines. Math (Metric and Standard Measurement Conversions) and Language Arts (Writing Process, Speaking, Technology) will also be covered during the research process.
