Birding D. C.

Washington, D.C. is the capital of the United States, founded on July 16, 1790. The City of Washington used to be a separate municipality within the District of Columbia until an Act of Congress in 1871 effectively merged the City and the District into a single entity. It is for this reason that the city, while legally named the District of Columbia, is known as Washington, D.C. The city is located on the north bank of the Potomac River and is bordered by the states of Virginia to the southwest and Maryland to the other sides. The District has a resident population of 588,292; however, due to commuters from the surrounding suburbs, its population rises to over one million during the workweek. The Washington Metropolitan Area, of which the District is a part, has a population of 5.3 million, the eighth-largest metropolitan area in the country.

Article One of the United States Constitution provides for a federal district, distinct from the states, to serve as the permanent national capital. The centers of all three branches of the federal government of the United States are located in the District, as are many of the nation's monuments and museums.

Washington, D.C. has a total area of 68.3 square miles (177 km2), of which 61.4 square miles (159 km2) is land and 6.9 square miles (18 km2) (10.16%) is water.[36] . Washington is therefore surrounded by the states of Maryland to the southeast, northeast, and northwest and Virginia to the southwest. The District has three major natural flowing streams: the Potomac River, the Anacostia River, and Rock Creek. The Anacostia River and Rock Creek are tributaries of the Potomac

The U.S. National Park Service manages most of the natural habitat in Washington, D.C., including Rock Creek Park, the Chesapeake and Ohio Canal National Historical Park, the National Mall, Theodore Roosevelt Island, and Anacostia Park.[42] The only significant area of natural habitat not managed by the National Park Service is the U.S. National Arboretum, which is operated by the U.S. Department of Agriculture.[43] The Great Falls of the Potomac River are located upstream (i.e. northwest) of Washington.

Washington has a humid subtropical climate (Köppen climate classification: Cfa), typical of Mid-Atlantic U.S. areas removed from bodies of water, with four distinct seasons. The District is located in plant hardiness zone 8a near downtown, and zone 7b elsewhere in the city, indicating a temperate climate.[46] Spring and fall are mild, with low humidity, while winter brings sustained cool temperatures and annual snowfall averaging 16.6 inches (420 mm). Average winter lows tend to be around 30 °F (-1 °C) from mid-December to mid-February. Blizzards affect Washington on average once every four to six years. The most violent storms are called "nor'easters", which typically feature high winds, heavy rains, and occasional snow. These storms often affect large sections of the U.S. East Coast.[47]

Summers tend to be hot and humid, with daily high temperatures in July and August averaging in the high 80s °F (about 30 °C). The combination of heat and humidity in the summer brings very frequent thunderstorms, some of which occasionally produce tornadoes in the area. While hurricanes (or their remnants) occasionally track through the area in late summer and early fall, they have often weakened by the time they reach Washington, partly due to the city's inland location. Flooding of the Potomac River, however, caused by a combination of high tide, storm surge, and runoff, has been known to cause extensive property damage in Georgetown.
