The number of dead and dying Common Murres washing ashore along
Oregon's beaches has increased dramatically during the last week.
Murres floating ashore near Newport are approaching record numbers,
according to Robert Loeffel and his assistants, who have been
conducting year-round beach mortality transects on 4.6 miles of
beach just south of Newport for the past 28 years. Robert Loeffel, a
Newport resident and former Oregon Department of Fish and Wildlife
employee, has been collecting these data on a volunteer basis. On
Tuesday alone, 67 adult dead murres were recovered. The total for
the month of July now stands at 114, just 11 birds shy of the July
record of 125 recorded during the major El Nino event in 1983. The
July record will likely be surpassed later this week when their
surveys resume.
U.S. Fish and Wildlife Service biologists conducted a boat survey
between Newport and Depoe Bay on July 25, 2005, during which they
observed numerous dead and stressed murres along the shore and out
to 10-15 miles offshore. A report of dead common murres on the beach
at Pacific City on Sunday July 24, 2005, indicated a localized rate
of approximately of one dead murre every 75 feet. Dead murres on the
beach have also been reported at Cannon Beach.
The dieoff appears to involve adult birds and is likely the result
of stress due to a lack of food associated with unusually low
oceanic productivity along the west coast this year. Unseasonable
weather patterns in the spring and summer resulted in a general lack
of coastal upwelling, which drives the food chain along the coast.
"We are sending dead murre specimens to the U.S. Geological Survey,
National Wildlife Health Center on Wednesday to have necropsies
performed to determine the exact cause of death," said Roy W. Lowe,
Project Leader for the Oregon Coastal National Wildlife Refuge
Complex.
The rocks, reefs and islands within Oregon Islands and Three Arch
Rocks National Wildlife Refuges are closed to the public to protect
nesting habitat for the majority of Oregon's nesting common murres
and 11 other seabird species breeding along the Oregon coast. "It is
very important to continue to protect breeding sites as the murres
and other seabirds face these large scale natural mortality events"
said Lowe.
