Divergence in chick developmental patterns among wedge-tailed shearwater populations

Abstract: Mechanisms of population divergence in seabirds are poorly understood. We evaluated whether divergent patterns of chick development among wedge-tailed shearwater Puffinus pacificus populations are facultative responses to short-term fluctuations in food availability, or fixed colony-specific phenomena potentially associated with differences in local resource availability. Supplementary feeding at Heron Island increased food intake to levels equal to, or greater than, those observed at Lord Howe Island. In supp… Show more

“…Chick growth and survival amongst seabirds is influenced by several factors, including prey availability (Litzow et al 2002, Elliott et al 2010, parent requirements and resource allocation (Weimerskirch et al 1997), meteorological conditions (Yoda & Ropert-Coudert 2007, Weimerskirch et al 2012, predation (Mullers & Tinbergen 2009) and life-history plasticity (McDuie et al 2013). An adult seabird's time-activity budget can be used as a measure of some of these factors (e.g.…”
