INFANTICIDE OF WEDGE-TAILED SHEARWATER PUFFINUS PACIFICUS CHICK AT MARINE CORPS BASE HAWAII
Colonial seabirds are highly susceptible to the effects of conspecific aggression. Their close proximity during the nesting period may result in an increased frequency of aggressive encounters and facilitate their detection (Mock 1984, Clode 1993, Parkes 2005).

| Summary: | Colonial seabirds are highly susceptible to the effects of conspecific aggression. Their close proximity during the nesting period may result in an increased frequency of aggressive encounters and facilitate their detection (Mock 1984, Clode 1993, Parkes 2005). In seabirds, conspecific aggression can occur between adults, between adults and chicks or between chicks, and is thought to increase when environmental conditions are poor (Ashbrook et al. 2008). In years of low food availability in Common Guillemots (Uria aalge), adults leave chicks unattended for longer periods, resulting in increased attacks from neighboring adults (Ashbrook et al. 2008). Similarly, Fetterolf (1983) found that low food availability not only increased attacks on Ring-billed Gull Larus delawarensis chicks from neighboring adults, but also increased the frequency of chicks leaving the nest to beg for food from neighboring nests. This behavior can result in either voluntary feeding or aggression, depending on |
