This is my favorite site for bird identification. They have multiple pictures of each species, pictures of similar species, range maps, and much more. The page design makes it easy to access a wealth of information easily
eBirdWhen I first started bird watching this was the site that got me excited about bird watching. You can report your bird sightings here and eBird will keep track of your bird lists for you. Bird sightings are stored along with the location of the sighting so you can plan your bird watching trips around the birds you want to see. If you have competitive tendencies like me, there are top 100 lists that track how many birds observers have seen in a particular location, county, state, etc. You will also be contrbuting to a very successful citizen science project.
Madrone Audobon SocietyThis is my wonderful local Audobon Society. I love going on the bird walks with this group. I have learned so much about bird watching from the experts that lead the bird walks and the many skilled birders that join the walks. If you want to get involved in Sonoma county bird conservation this is a great group to start with.
