Study predicts big changes in bird species composition in US NPs as climate warms
They were not supposed to be there, but they were: More than 100 brown-hooded, white-breasted seabirds, along with four nests, at chilly Channel Islands National Park off California's coast. This was not balmy Baja California, which normally is the northern-most range for tropics-loving Brown boobies, but rather a windswept chain of islands with average high temperatures in the mid-60s and brisk water temperatures in the 50s.
While the islands that comprise the national park have been called the "Galapagos of North America," Brown boobies are still an unusual addition. Yet their move north could be among the first of many by bird species trying to adapt to warming climates brought on by the world's growing greenhouse gas emissions.
