About the Cam:
This nest is located on the Chesapeake Bay near Annapolis Maryland. Tweedledee and Tweedledum (the resident osprey couple) took over the nest on May 2, 2018.
The Chesapeake Bay is an estuary in the U.S. states of Maryland and Virginia. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula with its mouth located between Cape Henry and Cape Charles.With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others. More than 150 major rivers and streams flow into the Bay's 64,299-square-mile drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of Washington, D.C.
The Bay is approximately 200 miles long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocean. It is 2.8 miles wide at its narrowest (between Kent County's Plum Point near Newtown and the Harford County shore near Romney Creek) and 30 miles at its widest (just south of the mouth of the Potomac River). Total shoreline including tributaries is 11,684 miles, circumnavigating a surface area of 4,479 square miles. Average depth is 21 feet, reaching a maximum of 174 feet. The Bay is spanned twice, in Maryland by the Chesapeake Bay Bridge from Sandy Point (near Annapolis) to Kent Island and in Virginia by the Chesapeake Bay Bridge-Tunnel connecting Virginia Beach to Cape Charles. Known for both its beauty and bounty, the Bay has become "emptier", with fewer crabs, oysters and watermen in past years. Recent restoration efforts begun in the 1990s have been ongoing and show potential for growth of the native oyster population. The health of the Chesapeake Bay improved in 2015, marking three years of gains over the past four years, according to a new report by the University of Maryland.
The osprey is a diurnal, fish-eating bird of preywith a cosmopolitan range. It is a large raptor, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts.
The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant.
Ospreys breed near freshwater lakes and rivers, and sometimes on coastal brackish waters. The nest is a large heap of sticks, driftwood, turf or seaweed built in forks of trees, rocky outcrops, utility poles, artificial platforms or offshore islets. Generally, ospreys reach sexual maturity and begin breeding around the age of three to four, though in some regions with high osprey densities, such as Chesapeake Bay in the U.S., they may not start breeding until five to seven years old, and there may be a shortage of suitable tall structures.
Ospreys usually mate for life. In spring the pair begins a five-month period of partnership to raise their young. The female lays two to four eggs within a month, and relies on the size of the nest to conserve heat. The eggs are whitish with bold splotches of reddish-brown and are about 6.2 cm × 4.5 cm (2.4 in × 1.8 in) and weigh about 65 g (2.3 oz). The eggs are incubated for about 35–43 days to hatching. The newly hatched chicks weigh only 50–60 g (1.8–2.1 oz), but fledge in 8–10 weeks.
