Bald eagle population in Prince William sound after the Exxon Valdez oil spill
Article Abstract:
Researchers surveyed bald eagle populations in Prince William Sound in 1989, 1990, 1991 and 1995 to investigate the long-term effects of the Exxon Valdez oil spill. The oil spill in Mar 1989 affected extensive areas of the Alaskan coastline, and an estimated 247 bald eagles died due to the contamination. Earlier research reported the negative effects on bald eagle reproduction success in 1989. However, this survey revealed that the bald eagle population had recovered to pre-spill levels by 1995. The researchers estimated that the adult bald eagle population was 2,641 in 1995, compared to 2,199 in 1989.

The Exxon Valdez oil spill disrupted the breeding of black oystercatchers
Article Abstract:
The grounding of the T/V Exxon Valdez in Prince William Sound, AK, in 1989 caused an environmental catastrophe in the region and exposed birds to oil pollution for long periods of time. Black oystercatchers were especially vulnerable, depending entirely on marine shorelines for their food and habitats. A survey of breeding populations of oystercatchers in Prince William Sound shows disturbance during 1989 and 1990, although populations were generally recovering in 1991. It is concluded that the cleaning of heavily oiled shorelines is beneficial to the breeding success of black oystercatchers.

Bald eagle survival and population dynamics in Alaska after the Exxon Valdez oil spill
Article Abstract:
The effect of the 1989 Exxon Valdez oil spill on bald eagle population was investigated. Some 159 bald eagles in Prince William Sound, AK, were radio-monitored for less than three years four months after the accident to determine their 'age-specific' survival rates. The results, which showed nearly similar survival rates for eagles in the oiled and unoiled areas, suggests that any adverse effect of the disaster occured prior to the experiment.
