EBird.org is a really cool free web site by the Cornell Lab of Ornithology and the National Audubon Society where you record what you saw, where you saw it, and when you saw it. It will then construct all kinds of lists, charts and maps for you, either from your records or from all records in your area. For example, you can find out what birds other people are seeing nearby, and for a bit of good natured competition you can even see who has the biggest lists of birds seen this month, this year and for their entire life.
Here's a list of birds seen recently in our neighborhood, as reported to EBird.org. Pick a different location from the drop-down list to find out what's been seen near there recently. Observations submitted are usually visible here within 24 hours, so come back often! Choose a location close to you to find out what's in your neighborhood!
Scroll down the page to see a map where you can chart individual bird sightings!
Here's a map where you can display recent Corvallis area sightings of a particular bird recorded at EBird.org. Just pick the bird you're interested in from the drop-down list. Hover the mouse over a sighting marker to see more details.
You can also drag the map around and zoom it in and out, and when you pick a new bird in the drop-down list it will redisplay the map at it's current position with markers for the new bird. This way you can see what birds people are seeing anywhere in the country, or anywhere in the world for that matter!
