Duck Behavior, New Tech, and the Challenges of Conservation | Gamebird University #527 01/28/2026

Duck Behavior, New Tech, and the Challenges of Conservation | Gamebird University #527 In this episode of Gamebird University, hosts James Callicutt and Mark McConnell sit down with Dr. Frank Rohwer, President and Chief Scientist of Delta Waterfowl, for a wide-ranging conversation about waterfowl research, management, and conservation. The trio reflects on Frank’s long career—from his early academic days at LSU to leading Delta’s scientific programs—and explores the questions and challenges in understanding duck behavior and habitat use. They talk about how weather and temperature shape ducks’ movements and foraging habits, sharing surprising insights about when ducks feed, move, and seek refuge across varying temperatures. The conversation delves into advances in GPS and transmitter technology that have opened new windows into waterfowl movements, as well as long-running studies of ring-necked ducks that reveal unexpected connections between southern wintering areas and western boreal breeding grounds. Throughout the episode, the group explores new methods for assessing duck production, including the use of drones and thermal imaging to locate nests, track brood survival, and measure reproductive success. They also discuss the role of predator management in boosting duck production and the growing focus across wildlife disciplines on making conservation more cost effective. The puzzling range expansion of black-bellied whistling ducks emerges as a point of discussion, along with questions about the species’ ecology and its future impacts across southern landscapes. The conversation also touches on the role ducks, quail, and pheasants play as vital ecosystem services that benefit rural economies and wildlife heritage. At its heart, this episode captures the deep connections between hunters, researchers, and their dogs, reminding listeners why waterfowl conservation matters—not just for its ecological benefits, but for the traditions, stories, and shared passions that accompany it. /episode/index/show/naturalresourcesuniversity/id/39886215
