My current focus of research is to: • Identify the main foraging habitats of Wedge-tailed shearwaters (Ardenna pacifica) used during the breeding and non-breeding periods to determine if they are foraging locally or further afield and if birds from two different latitudes are utilising similar or different habitats and therefore applying different foraging strategies. • Measure and compare colony productivity between two different latitudes. • Identify and compare diet compositions of birds from the two colonies and establish whether this is influencing colony productivity. • Measure and compare at sea habitat use and foraging strategies of birds from two different latitudes, between El Niño and La Niña years to establish any potential influence on productivity.
