The Marbled Murrelet is a small diving seabird that breeds in coastal older-aged forests from Alaska to California. In the lower 48 states, the Marbled Murrelet is an endangered species, suffering from a variety of threats that include habitat fragmentation, habitat loss, oil spills, and depredation. In the Spring of 2006 (the second season of a three-year study) a 15-member team will be working out of Port Snettisham, Alaska under the direction of Dr. Scott Newman, formerly of Wildlife Trust. The first year of the study focused on foraging ecology, foraging habitat preference, attendance patterns in Port Snettisham during chick rearing, and post-breeding dispersal.  Blood analyses will be performed to compare the health of the Marbled Murrelet of Alaska (a relatively pristine environment) to the health of the threatened Marbled Murrelet population of central California. This year and the third year of the study will focus on additional health assessments and understanding nest site selection and nest stand preferences of Marbled Murrelets.
