John currently conducts research on the life cycles of migratory birds, with a focus on breeding biology. He also works on the non-breeding component of some species as well. He currently studies the Painted Bunting in North and South Carolina as well as other species including: Black-throated Green Warbler (NC), Swainson’s Warbler (NC/SC), Golden-winged Warbler (Nicaragua), and Worm-eating Warbler. John also worked on a collaborative study of breeding Yellow-bellied Sapsuckers in NC. John primarily uses radio telemetry to study space use, nesting chronologies and reproductive success.
