I will say this up front: I am not an expert birder. I like birds, I can identify most the ones that come through my yard, and when Matt quizzes me on bird calls as we're hiking, I have about a 50-50 chance of being able to say what that bird is.
If you're not one of these people, consider going out birdwatching with one of these groups sometime, and see (and hear) what you're missing. (And if you are one of those people, please comment and let me know if I missed anything!)
Maryland Ornithological Society has meetings and field trips all over Maryland, including some in Rock Creek Park. Their September/October schedule is nine pages long!
Audubon Naturalist Society has free birding trips in the metro area and beyond. Also look through their catalog for paid classes and trips that focus on birds -- there are many.
Prince George's Audubon Society has regular walks on 1st and 3rd Thursdays at Lake Artemesia, and 1st and 3rd Saturdays at Patuxent River Park.
The Audubon Society of Northern Virginia has classes, programs, and field trips at local sites like Huntley Meadows, Riverbend Park, and many others.
The Northern Virginia Bird Club lists a couple of outings a week on their calendar as well.
The Nature Conservancy has free birding outings for members about once a week this fall.
