Abstract

The homing behavior of 379 Ring-billed and 50 Herring Gulls was contrasted with sky conditions that existed at release times. No evidence was obtained that supported the use of sun or stars as orientational cues. Gulls responded to topographical features during some trials. Juvenile Ring-billed Gulls showed directional preferences that correspond to headings required to reach the population's winter range.
