Effects of the Exxon Valdez oil spill on murres: A perspective from observations at breeding colonies. Bird study number 3. Exxon Valdez oil spill state/federal natural resource damage assessment final report
The authors surveyed murres (Uria spp.) annually from 1989 through 1991 at breeding colonies within the trajectory of the oil to determine whether numbers had declined and to evaluate the effects of oil on nesting phenology and reproductive success, following the 1989 Exxon Valdez oil spill. The colonies the authors surveyed contained the majority of the estimated 200,000 murres attending colonies in the affected area, and they found reduced numbers at all study colonies following the spill. In addition, nesting was delayed and productivity rates were far below normal following the spill. In contrast, numbers of murres did not decline and reproductive parameters were normal at 2 colonies the authors surveyed outside the trajectory.
