ICE Ecocystems: Ivory gull

The ivory gull research project in ICE will document diet, nest attendance, hatching success, and body condition as well as providing precise information regarding where animals are foraging at-sea, assessing habitat use, and home range size via the deployment of GPS-data loggers and satellite transmitters.

The specific primary hypotheses addressed: receding ice edges in the north will result in ivory gulls suffering reduced breeding success, declines in body condition, increased home range size and use of suboptimal foraging areas and suboptimal prey types.
