Coastal Mississippi shorelines are increasingly altered by erosion, development, and shoreline armoring, yet little is known about how these changing environments affect coastal bird communities. The Back Bay of Biloxi, a key migratory corridor within the Mississippi Flyway, contains a mosaic of natural fringing marshes and hardened shorelines that differ in habitat structure, prey availability, and suitability for coastal birds. This ongoing study examines how avian species richness and abundance vary between natural marsh and riprap shorelines across the central Back Bay. Sixteen wildlife cameras were deployed across nine natural marsh and seven riprap sites, representing a gradient of habitat condition and human disturbance. The cameras capture images every five minutes during two-week sampling periods occurring bimonthly throughout the year. Imagery is processed through the online Zooniverse project “Back Bay Bird Identification,” where citizen scientists assist with identifying bird species and managing the large photo dataset. Vegetation structure and seasonal nekton sampling provide additional ecological context for interpreting patterns of shoreline use. This poster presents preliminary findings from the first phases of data collection and highlights how citizen science involvement is advancing our understanding of bird–shoreline relationships in the Back Bay of Biloxi.
