Whooping Crane Research:
- Research in migration and avian behavior, primarily training whooping cranes to follow ultralight aircraft on a migration
- Research to improve methods for reintroducing whooping cranes into the wild, including parent-rearing whooping cranes, studying whooping crane behavior, studying the effects of breeding cranes for multiple generations in captivity as compared to wild cranes
- Research on the ecology and behavior of waterfowl, primarily seaducks using implanted satellite transmitters
- Research about new and emerging diseases of waterfowl, including Wellfleet Bay virus and avian influenza virus

Whooping Crane Restoration
At more than five feet tall with brilliant white plumage, black primary feathers, a red cap, and yellow eyes, the highly endangered Whooping Crane (Grus americana) is one of the most spectacular birds native to North America. In 1942 there were fewer than 20 birds in the flock that migrates from Wood Buffalo National Park in Canada to Aransas National Wildlife Refuge in Texas. An additional six...
A Vaccination Program to Protect Endangered Whooping Cranes from Encephalitis Virus
The Challenge: In eastern North America there is a viral disease called Eastern Equine Encephalitis, or EEE. This virus is transmitted among native bird species by the mosquito, Culiseta melanura, but does not cause disease in these passerine species. However, the virus is capable of causing severe disease or death in horses, some game bird species, humans and whooping cranes. In the fall of 1984...
The Release of Parent-reared Whooping Crane Colts into the Eastern Migratory Population
The Challenge: Whooping cranes have been successfully introduced using costume rearing techniques in either a direct autumn release or in an ultralight led migration from Wisconsin to Florida. In Florida, we have also released parent-reared whooping cranes. Not much is known about the learning that takes place in this K-selected species over the almost one year that the young whooping crane colt...
Migration and Habitat Use by Seabirds in the Atlantic Flyway: Evaluation of Potential Impacts of Proposed Wind Farms
Overall, this study tracked movements of over 400 individuals of three species over the course of five years; one of the most comprehensive satellite tracking studies of marine birds ever conducted in Atlantic North America. Results provide a better understanding of how diving birds use offshore areas of the mid-Atlantic U.S. and beyond, and, in combination with results from other types of...
Effects of Dorsally Mounted Solar-powered Cellular GPS Transmitters on Diving and Foraging in Surf Scoters and Red-throated Loons
Several types of experimental attachment techniques were tested on each study species (Surf Scoters (Melanitta perspicillata), Red-throated Loon (Gavia stellata), and Northern Gannet (Morus bassanus)), including traditional Teflon-ribbon style harnesses, sutures, and harnesses made of silicone moulding. Silicone harnesses, which were deployed in 2014 and 2015, offered the best balance between high...
In-Air and Underwater Hearing Abilities of Seabirds
As diving foragers, sea ducks are vulnerable to underwater anthropogenic activities, including naval sonar activity and gillnet fisheries. Bycatch in gillnets is a principle driver of mortality for sea ducks, killing hundreds of thousands of seabirds annually. To reduce gillnet bycatch, underwater hearing tests were conducted on affected sea duck species to assist with possible development of...
