... in a colonial seabird, the king penguin ( Aptenodytes patagonicus ). We subjected 77 birds (44 males, 33 females) at various stages of incubation and chick-rearing to three experimental stressors (metal sound, distant approach and capture) known to vary both in their intensity and associated risk, and monitored...

... measured under freely living conditions if the energy equivalent of M b loss is known. Interestingly, the composition of M b loss, and thus its energy equivalent, is constant in phase II fasting animals. This observation is consistent for seabirds ( Groscolas, 1988 ; Groscolas et al., 1991...

... behavioural repertoire, De Leon et al.( De Leon et al., 2003 )concluded that the function of familiar odour recognition was to facilitate homing to the correct burrow. Among birds, the Procellariiformes (`tube-nosed' seabirds) are known for their excellent sense of smell. Many species use olfactory cues...

... flight should be higher in heavier birds. Based on this premise, we developed a new methodology using animal-borne accelerometers to estimate fine-scale temporal changes in body mass of a pursuit-diving, piscivorous seabird, the European shag, Phalacrocorax aristotelis . We hypothesized that variations...

Haney et al.( 1992 ) calculated that the mean horizontal distance over which procellariiform seabirds were recruited visually to a feeding flock was around 4.5 km and even proposed a theoretical limit of 20–30 km. It is evident, therefore...
