Diving pattern and performance in nonbreeding gentoo penguins (Pygoscelis papua) during winter
, and compared foraging behavior with that of breeding (chick-rearing) birds. Foraging was highly ... diurnal with 98% of foraging trips completed during the same day. Foraging-trip frequency was 0.8/day ... , trip duration was 6-8 h, and birds spent 51-62% of the foraging trip diving. Dive depth and duration ... were bimodal. Shallow dives (30 m; 55% of total number and 81% of dive time) averaged 74-105 m and 2.7 ...
