Population Levels and Reproductive Performance of Murres Based on Observations at Breeding Colonies, 1992

An assessment of damage to murre populations and reproductive performance due to the 1989 Exxon Valdez oil spill was conducted from 1989 to 1991. In 1992, we continued monitoring these parameters at three murre nesting colonies located in the path of the oil in an effort to begin measuring recovery....

Description
Summary:An assessment of damage to murre populations and reproductive performance due to the 1989 Exxon Valdez oil spill was conducted from 1989 to 1991. In 1992, we continued monitoring these parameters at three murre nesting colonies located in the path of the oil in an effort to begin measuring recovery. Numbers of murres were significantly reduced at all three study colonies following the spill. We found no recovery to pre-spill numbers. Timing of breeding and productivity of murres at the Barren Islands and Puale Bay returned to near normal levels in 1992. This dataset includes 1) Counts of murres at Barren Islands, Chiswell Islands, and Puale Bay. 2) Dates common murre eggs were first observed. 3) Common murre chicks per adult.
