Study links seabird deaths to soap-like foam produced by red-tide algae
In late 2007, hundreds of dead and stranded seabirds washed up on the shores of Monterey Bay, their feathers saturated with water and coated with an unknown substance. After an intensive investigation, scientists determined that a massive "red tide" bloom of marine algae had produced a foamy soap-...
High hormone levels in seabird chicks prepare them to kill their siblings
The Nazca booby, a Galpagos Island seabird, emerges from its shell ready to kill its brother or sister. Wake Forest University biologists and their colleagues have linked the murderous behavior to high levels of testosterone and other male hormones found in the hatchlings.
The study appears in...
Overfishing may drive endangered seabird to rely upon lower quality food
The effects of overfishing may have driven marbled murrelets, an endangered seabird
found along the Pacific coast, to increasingly rely upon less nutritious food sources, according to a new study by biologists at the University of California, Berkeley.
