Dying seabirds
Saturday, March 18, 2006 11:32 AM PST
WHAT: CoastWatch volunteers and other people who monitor beaches on the Oregon Coast have noticed an unusual number of dead rhinoceros auklets. These small seabirds typically live way offshore, diving to catch small fish for food. They tend to breed in offshore island colonies by digging burrows in the ground for nests. Coastal Obervation and Seabird Survey Team reports have estimated as many as 20 to 30 auklets washed up per mile on Oregon beaches over the past two weeks.
OTHER SPECIES: Beach hikers from Astoria to Brookings also reported finding dead Cassins auklets, an ancient murrelet, common murres, northern fulmars, fork-tailed storm petrels, horned and tufted puffins, western grebes, short-tailed shearwaters and a western gull. They were not at unusual numbers.
WHY: Scientists don't know.
LONGTERM EFFECT: Possibly no harmful effect. Rhinoceros auklets are not threatened. There are hundreds of thousands of them ranging offshore from Central California to Alaska.
