The use of photograph identification databases over traditional capturing techniques is a less invasive method of analyzing animal behavior. Photo ID allows for tracking individuals of a species and estimating a variety of important population characteristics including residency, survival, and ultimately population size. Along the northern Gulf of Mexico, sea turtles are increasingly using artificial structures as habitats, for example, fishing piers. The number of sea turtles accidentally captured at fishing piers along the Gulf Coast has increased, with the Navarre Beach Fishing Pier having the highest rates in the state. To better understand the patterns of sea turtle occupancy of the Navarre Beach Fishing Pier, we developed a photograph identification database. Field surveys for this study were conducted at the Navarre Beach Fishing Pier over the summer, fall, and winter seasons.  A camera with a high zoom function was used to photograph an observed sea turtle’s head and facial scales, and the location of the turtle in proximity to the pier was recorded. Photos were uploaded to the 13S pattern software and were annotated so each individual entry could be compared to other previously uploaded photos to determine if the sea turtle was resighted. We analyzed the patterns of observed sea turtles to determine if there were temporal patterns in occupancy. In addition, as we were able to document individual resightings, we determined if individuals were residents or transients to the fishing pier. Over the course of the summer season, there were 23 recorded resightings, and 50 individual sea turtles observed over 64 days; thus 46% of turtles observed at the fishing pier have some degree of sustained occupancy. Our results can be used to understand patterns of sea turtle occupancy at fishing piers and provide scientific guidance to reduce bycatch at fishing piers along the Gulf Coast.
