发帖数: 18873 | 6 A seabird rarely seen in the U.S. has mysteriously descended on Southern
California, and bird watchers are scrambling to catch a glimpse before the
bird vanishes.
The Blue-footed Booby, a brown-and-white bird with distinctive bright blue
feet, is native to the warmer waters of Mexico and can be found along coasts
as south as Peru. But the birds have recently been spotted in small flocks
along the coast of central and southern California.
It's been spotted for the first time in Los Angeles County since 2007.
"No one really knows why and so people are kind of going nuts," said Daniel
Cooper, a Los Angeles-based independent biologist and consultant. "These
things they disappear and maybe you won't see them for another 1,500 years."
The reports of Blue-footed Booby sightings have caused a stir among bird
watchers. On Wednesday morning, Cooper said four appeared in Marina del Rey.
"It has that goofy sort of seabird look," Cooper said. "It just kind of
looks silly."
The birds' arrival could be due to changing food sources or water
temperatures, or the species could be in the middle of a northern expansion,
Coopers said.
So, where can Southern Californians see the elusive Blue-footed Booby?
"It's somewhat unpredictable," Cooper said. "Anywhere where they can see
pelicans, they have a good shot of seeing a booby." |

样的。取决于内环境吧。

Blue-footed Boobies Invade California!

Over the past week Blue-footed Boobies have been reported with increasing
frequency from many places along the coast of southern California. As many
as seven birds are at the Playa del Rey–Breakwater, and at least one bird
has made it as far north as the Pt. Reyes Lighthouse. Birders on the Pacific
Coast should be on high alert for this species. Even more remarkable is the
number of birds being seen at inland lakes. From southeast Arizona to Los
Angeles and Riverside Counties, birders have turned up wayward Blue-footed
Boobies. Keep this species on your radar when birding any body of water in
the Southwest, and make sure to enter all your observations into eBird!
