This July, researchers from the U.S. Geological Survey and National Park Service discovered that California Common Murre (
Uria aalge californica) chicks had hatched on the Channel Islands for the first time since 1912.
Murres are football-sized seabirds with the tuxedo colors of penguins - except they can both fly in the air and dive down to 500 feet underwater. Historically, murres nested on Prince Island - a small islet off San Miguel Island within Channel Islands National Park. This colony disappeared nearly a century ago, likely a result of human disturbance and egg harvesting.
In California, Common Murres are most abundant off central through northern California with tens to hundreds of thousands of birds nesting at the Farallon Islands, off Trinidad Head, and at Castle Rock National Wildlife Refuge.
"This is an exciting finding - certainly a historic one," says Josh Adams, a seabird ecologist with the USGS Western Ecological Research Center. "The murres appear to have reestablished their former southern range, perhaps benefitting from present ocean conditions."
This new colony is perched on 100-foot-high sea cliffs, and was spotted by Adams, USGS biologist Jonathan Felis and their Channel Islands National Park colleagues Laurie Harvey and David Mazurkeiwicz during their research trips to this remote windswept island this summer.
