Research Interests

  • Breeding biology of Swainson’s Warbler (Limnothlypis swainsonii) at two Coastal Plain locations, along the Roanoke River in eastern NC and the Great Pee Dee River in SC. 
  • Breeding biology and population genetics of southern Applachian Yellow-bellied Sapsucker (Sphyrapicus varius appalachiensis). 
  • Breeding biology, population status, and a “Citizen Science” component, of the southeastern population of Painted Bunting (Passerina ciris).
  • Breeding status and conservation needs of Black-capped Petrel (Pterodroma hasitata) in Haiti.
  • Breeding bird communities within managed landscapes in North and South Carolina.
  • Morphometrics and population genetics of Wayne’s Black-throated Green Warbler (Dendroica virens waynei).
  • Morphometrics and population genetics of selected southern Appalachian species.

Grants and other support from the USFWS, SC DNR, NC Wildlife Resources Commission, NPS and private groups support much of the field and lab work.

Painted BuntingJohn Gerwin is the Chairperson for the Scientic Council on Rare, Threatened, and Endangered Birds of NC.  He serves on the Board of the Wake Audubon Society, and the Important Bird Areas Technical Committee for Audubon NC.  He serves on the NC Partners In Flight advisory committee, and co-advises graduate students at NC State University.  He co-leads nature-watching tours to local, national and international locations. He has been co-leading an annual bird banding/ecotour trip to a Shade-coffee plantation in northern Nicaragua since 2005.
