White pelicans are distinctive. Their 9-foot white wings are black tipped, and can create a bit of a mirage when they fly, seemingly appearing and disappearing as they go. Some observers have mistakenly reported them as UFOs. The birds also have notable long orange beaks and the largest wingspan of any other bird in Oregon.    

Their populations have increased considerably over the past few decades, and more recently, some pelicans have been spotted staying along the coast and in the Columbia River Basin for longer than expected. Scientists would like to know more about why and what the implications could be for the wider ecosystem. We learn more about white pelican colonies in the Pacific Northwest and how climate change may factor into the health of these birds from James Lawonn, an avian biologist at the Oregon Department of Fish and Wildlife.
