About the Program
Covia Holdings Corporation, Hephzibah Georgia Plant, located in Hephzibah, GA, is a nonmetallic mineral mining & quarrying industry producing clay products. Covia is implementing a qualifying project in Species – Avian - Eastern Bluebirds. The 290-acre site of mixed hardwoods, hayfields and longleaf pines is maintained by regular burning, thinning and species management by the Covia Hunt Club. On-the-groundwork for the project began in May 2004. 11 nest boxes with predator guards are in locations that provide shelter to promote hatchlings. The conservation objectives are to promote eastern bluebirds by installing and maintaining nest boxes, collecting, and sharing nesting data, controlling predators from entering or utilizing the nest boxes and promoting the eastern bluebird and songbird conservation through education for employees and public. Employees and partners (St. Michaels Episcopal Church Youth Group, North American Bluebird Society, Georgia Department of Natural Resources Wildlife Division) are engaged in project implementation, and are engaged in training, box construction and guidance. The project aligns with The North American Bluebird Society at web link

Practices and Impacts
  • In 2019, volunteers constructed new nest boxes with the Cornell Ornithology design which have smaller entrance holes, using cedar wood. In January 2020, 11 nest boxes were installed on metal poles with predator guards. Predator guards are installed to prevent predators from entering boxes.
  • The Team conducts nest monitoring weekly on calm dry days to reduce the chance of chilling chicks or eggs. The observer creates noise as she approaches the box to get the bluebird to leave the nest.
  • Since replacing the nest boxes, the 2020 data showed that there were 7 nest boxes that had nests, 5 of those boxes are occupied by bluebirds and had eggs that grew into fledglings. 2 boxes produced 2 successful broods within a year.
