Feeding and Chick Rearing Areas of Common Loons
Journal of Wildlife Management
We characterized the feeding and chick-rearing areas used by 16 resident pairs of common loons (Gavia immer) on 3 large lakes in Maine. Adults preferred water depths of 1.1-2.0 m and avoided depths >3 m for feeding in most breeding territories. Chicks were kept in shallow water areas (<2 m) close to shore (<150 m). Deep water areas (>3 m) distant from shore were avoided by chicks and adults. We suggest that near-shore recreation may be more detrimental to loons than man's activities in deep, open water.
