Fortunately, there were inspiring highlights, like bald eagles, rusty blackbird and lots of red-bellied woodpeckers, a southern species that has taken a tenacious hold here, thanks to global warming -- and a snowy owl and northern shrike

With the guide's release, out-of-towners will learn what local birders already know: that the Yaquina Head Outstanding Natural Area is the closest place you can get by land to a colony of 65,000 common murres; that Sally's Bend in Newport is a great place to see northern shrike
, American pipit and all six species of grebes; and that Sweet Creek Falls near Mapleton offers glimpses through old growth trees of the American dipper, a grey-colored songbird that walks under swift-running streams, eating cranefly larvae.
