Piping Plover Study

GCBO was awarded a one year contract from Texas Parks and Wildlife Division to census sand plovers along the Upper Texas Coast. The study focused mainly on Piping Plovers but Snowy and Wilson's Plovers were also included. Beginning in January 2008 , we surveyed plovers on the UTC and recorded numbers of birds, habitat characteristics, and human disturbance. Although regular Piping Plover surveys occur on the breeding grounds, there were no recent winter surveys on the UTC in Texas prior to this study. These data enabled our staff ornithologists to determine the habitat characteristics preferred by wintering plovers, determine if there are any threats to those habitats, and estimate the population size supported by the UTC in winter.
Abstract from Final Report:
We surveyed the upper Texas coastline from the mouth of the Sabine River to the mouth of the Colorado River, a straight-line distance of about 200 km. between January 2008 and January 2009. We recorded 1131encounters with Piping Plovers at 748 locations marked by GPS coordinates. We observed any interactions between Piping and Snowy and Wilson's Plovers which share the same coastline and recorded color marked Piping Plovers so we could observe the movements of uniquely marked birds. We compared our GIS data with published Designated Critical Habitat areas for the species. We attempted to measure human disturbance as a factor in Piping Plover wintering distribution by comparing our survey results between a moderately heavily used beach with an adjacent beach with little or no human disturbance. Our study was seriously interrupted by landfall of Hurricane Ike at approximately the mid-point of our study area in mid September. The storm affected the distribution of Piping and other small "sand plovers" and we attempted to document the movements of plovers in response to the severe habitat alteration caused by it. Finally, based on a year of observation of Piping Plover distribution we attempted to assess any imminent threats to the areas where relatively high numbers of Piping Plovers were consistently encountered.
