... 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...

... odour learning individual odour seabird Procellariiformes Among birds, the Procellariiformes (`tube-nosed' seabirds) are known for their excellent sense of smell. Many species use olfactory cues to assist them in both locating productive areas for foraging( Nevitt, 2000 ) and area-restricted...

... 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...
