-averse due to high future reproductive potential compared to shorter-lived organisms and to those with lower future reproductive potential (von Merten & Siemers, 2012). Seabirds are among the longest-lived animals, with greatly delayed senescence compared to other birds (Ricklefs, 1998 ), suggesting that

seabird that breeds in south-east Asia (Oka, 2004 ). Our previous study examined the migratory behaviour of streaked shearwaters using light-based geolocators, and showed three distinct wintering areas during non-breeding period: the seas off northern New Guinea, Arafura Sea and South China Sea (Yamamoto

specifically constrains animal pathways (i.e., spatial positions over time) as traveling animals move towards a goal. In some seabirds of the families Procellariidae (e.g., shearwaters, petrels) and Alcidae (e.g., auklets), arrivals of breeding birds at the colony at the end of foraging trips are restricted to

varying tag effect cast doubt on the biological relevance of many studies, as tagged individuals were not behaving normally. Seabirds are a popular subject for tag-enabled migration tracking, as they are highly mobile and tend to inhabit remote areas, far from direct land observation for the majority of

The lizard Ameiva corax (Censky and Paulson, 1992 ) is a diurnal, terrestrial, active forager endemic to a small island off the coast of Anguilla, British West Indies. Their diet includes a wide range of food types including seabird eggs, fish scraps, prickly pear fruit, invertebrates, and the

enhancement (LE, Roberts, 1941 ; Thorpe, 1951 ) is a form of social facilitation that verges on observational learning, defined as acquiring benefit from another’s experience through stimulus enhancement via observation (Pallaud, 1984 ; Goodenough et al., 2001 ). Seabirds are known to passively use

). The extent to which changes in sexual traits change with environmental conditions over time, however, has not been widely studied. Many seabirds exhibit sexually monomorphic colour ornaments (mutual ornamentation; e.g., Yellow-eyed penguin Megadyptes antipodes : Massaro et al., 2003 ; King penguin

, Memorial University of Newfoundland) (Accepted: 18 August 2006) Summary We investigated the behavioural context of pair (PCs) and extra-pair copulations (EPCs) in individually-marked socially-monogamous, long-lived seabirds, common murres ( Uria aalge ). Since forced EPCs have been documented for this

intruders. Summary Playback experiments were used to study the role of vocalization in mate attraction by Manx shearwaters, a nocturnal seabird. Pre-breeding birds were exposed to test calls of male and female shearwaters calling from the range of normal locations: above the colony as in a flyover call, on
