DC: WOLF TRAP PARK, SUNRISE VALLEY PARK, OCCOQUAN BAY NWR (7/13-15/06)

Technically this wasn't a birding trip. I was sent to DC for a work-related seminar. However, I did take the opportunity to make some side trips. The first trip was to Wolf Trap Park where I saw "Chicago", the second was a short stop at Sunrise Valley Park, and 3rd (and most special to me) was the Occoquan Bay NWR.
