Spent 4 days last weekend in Washington DC, with coincidental birding during long walks each day around the National Mall, with a species tally somewhere around 25.
(I had my "walk-around" lens (16-300mm) which is adequate for landscape and cityscape, but not that great for birds.)
Most entertaining sighting was a Red-tailed Hawk being mobbed by American Crows.
