The source of their information was Vanessa Blackstone, Oregon Parks and Recreation Department (OPRD) wildlife biologist. On her Nature Notes blog she said, "This is the first time in 30 years that we have a confirmed nest here, and [it] supports all the hard work Oregonians have done to help this species survive.”
More snowy plovers have been seen at Nehalem Spit since the first report and their numbers have been increasing along the northern Oregon coast in the last couple years.The most recent report from OPRD is from 2013. OPRD has a web site dedicated to snowy plover recovery because it's a species listed as endangered at both the state and federal levels, and they manage for both. According to their 2010 Habitat Conservation Plan there haven't been any snowy plover sighted on Bayocean since 2000.
The United States Fish and Wildlife Service also has a detailed snowy plover web site as well as a Pacific Region tumblr page.
