Fighting to save an endangered bird -- with vomit

Recommended Posts

An adult marbled murrelet, a rare and endangered type of bird, floats atop the water.
A psychological warfare program centered on vomit could help save the marbled murrelet, an endangered seabird that nests in California's old-growth redwood forests.


About 4,000 murrelets remain in California, with about 300 to 600 in central California's Santa Cruz Mountains. Squirrels, ravens and owls also swipe murrelet eggs, but jays are the biggest thieves in California, gobbling up 80 percent of each year's brood. Unless more eggs survive, the central California population will go extinct within a century, according to a 2010 study published in the journal Biological Conservation.

To boost California's murrelet numbers, biologists in California's Redwood National and State Parks are fighting back against Steller's jays and their human enablers.
