This is just plain impressive: http://www.birdingoregon.info/ A very thorough rundown of key birding areas in Oregon, this Birding Oregon Site Guide was developed by Chuck Gates, and from what I can see it doesn't miss much--this descriptive list of sites could keep a birder busy for a long, long time.
www.harneybirder.com One of the hottest new birding Websites out there, Tim Blount’s Harneybirder.com promises to deliver all the information you need for birding in what is arguably Oregon’s best birdwatching county, and Tim is off to a flying start. One of the best parts of this photo-heavy site is what amounts to a real-time log of recent notable sightings in the county, which is obviously very helpful for birders on the move in search of rarities. Coming soon to the site will be lots of information about locations, detailed reports from Tim’s frequent birding expeditions in the county, and articles by guest birders. If you are headed to Harney County, this site should be your first stop.
