The First State is visited by large numbers of songbirds. The marshes, wildflowers, and areas of brush provide ideal nesting and feeding habitat. Other songbirds inhabit the tall pine forests of Delaware. Warblers, nut hatches, sparrows, red wing blackbirds and others nest on the refuge in the summer, while cardinals, jays, woodpeckers and finches reside during the winter months.

Shorebirds

Herons, egrets, ibises, oyster crackers, marsh hens and other shorebirds are frequently spotted along the marshes of Delaware Bay. 

Delaware Bay beaches are famous for their spring bird migrations. Each year, countless numbers of ruddy turnstones, sanderlings, red knots, piping plovers, gulls, and other birds converge along Delaware Bay shorelines to feed on horseshoe crab eggs. Peak action usually occurs in mid to late May.

Birds of Prey

Delaware is visited by a number of birds of prey. Ospreys arrive in the spring to raise young and feed on the abundant fish stocks. As seasons change, some ospreys migrate south while other birds of prey migrate into the fields and forests of Delaware for the winter. American eagles, red tailed hawks and other large hunters are present in fall thru spring. Other hawks such as sparrow hawks may be found year-round.

Waterfowl

Ducks, geese, brant and swans all make stops in the marshes and refuges of Delaware. In the refuges, geese and swans take up residence year-round. Other full-time residents include black ducks which raise their young in the refuge and marshes.

In autumn, migrating ducks and geese visits Delaware wetlands. Arriving are shoveler ducks, pintails, mallards, widgeons, teal, rudy ducks, canvasbacks, redheads, ring necked ducks, bluebills, and others. Mergansers, buffleheads, goldeneyes, and other diving ducks show up in the bay waters as cold weather sets in. Off the coast, rafts of sea ducks forage along the shoals over the winter.

Pelagic Birds

The waters off the Delaware coast are visited by up to 30 species of pelagic birds including albatrosses, petrels, shearwaters, storm-petrels, phalaropes, skuas, jaegers, gulls, terns and alcids. These birds migrate along the offshore waters, many never see land on the eastern seaboard.

Barnegat Lighthouse | credit: USCG
Barnegat Lighthouse will be closed to visitors for approximately seven months for a $1.3 million restoration of the historic lighthouse, according to the New Jersey Department of Environmental Protection (DEP).

The lighthouse closure began Monday, March 14. Construction work through October will involve a complete exterior restoration of the lighthouse, masonry recoating and repairs to the brick facade, interior lantern steel platform repairs, roof repairs, and the installation of new windows. 

The lighthouse will remain dark for the duration of the project being done by Spartan Construction General Contracting, Inc. of South Amboy.

Scaffolding will also be erected for the entire height of the lighthouse. The restoration project is funded by the Corporate Business Tax.

As part of the restoration effort, the Friends of Barnegat Lighthouse will donate a new beacon light for the lighthouse as well as new security fencing. 

After being decommissioned in 1927, the Barnegat Lighthouse sat dark until January 1, 2009 when the Friends of Barnegat Lighthouse donated the current light.

Located on the northern tip of Long Beach Island, the Barnegat Lighthouse is one of the signature destinations along the Jersey shore and listed on the National Register of Historic Places.

Barnegat Lighthouse State Park will remain open during the renovation, including the park office, interpretive center, fisherman’s walkway, and trails. During the restoration, Americans with Disabilities Act access will not be available along the fisherman’s walkway.

Barnegat Lighthouse State Park is a popular destination for fishing, hiking, birding, picnicking, and other outdoor recreation.

Lighthouse enthusiasts can visit several historic navigational aids in New Jersey including Twin Lights Historic Site in Highlands, Absecon Lighthouse in Atlantic City, and Cape May Lighthouse in Cape May Point.

Hurricane Joaquin Damage - Mid Atlantic States

A variety of agencies in the USA have been involved in predicting and accessing damage from Hurricane Joaquin.

Coastal change experts from the U.S. Geological Survey (USGS) recently warned that although the path of Hurricane Joaquin continues to move farther offshore, a high probability of dune erosion existed along parts of the Atlantic coast, from the North Carolina Outer Banks to Cape Cod.

Area which could be affected include the Outer banks, Virginia, and Maryland, New England, the New Jersey and New York coast.

USGS issues coastal-change forecasts, which integrate information produced by both the USGS and National Oceanic and Atmospheric Administration and its National Hurricane Center. The forecasts are posted daily to the agency's Coastal Change Hazards Portal.

Portuguese Man O’ War Reported on Long Island Beaches

In July, Fire Island National Seashore (FINS) received reports of Portuguese Man O’ War at various locations on Long Island’s South Shore beaches.

On July 8 a visitor to Jones Beach, the barrier beach west of Fire Island, encountered and reported three Portuguese Man O’ War.

On July 1 there was a sighting at Fire Island Pines and, since that time, National Park Service (NPS) lifeguards found and buried four of the animals near Sailors Haven.

Notices and safety warning flags will be posted at visitor centers and on NPS lifeguarded beaches on Fire Island. If a public safety risk is identified, NPS lifeguarded beaches will be closed to swimming. Beaches within the towns of Brookhaven and Islip on Fire Island are taking similar precautions, according to NPS.

The Portuguese Man O’ War (Physalia physalis) has long tentacles with stinging cells used to capture its small fish prey. These stinging cells can cause a painful sting to humans, even after the animal has died.

Delaware Beaches Rated Number 1 in USA

Delaware’s beaches have been recognized for having the cleanest water quality in the nation. Delaware is also the location of two of the country’s few “Superstar Beaches,” according to the National Resources Defense Council (NRDC). The advocacy group annually assesses all beaches in 30 coastal states.

Beaches at Rehoboth and Dewey were awarded 5-star ratings as Superstar Beaches for their perfect swimming water quality for the past four years. They were two of only 13 Superstar Beaches so designated by the NRDC among beaches of the coastal states.

In its report, ”Testing the Waters” in Delaware, the NRDC also recognized DNREC’s Recreational Water Quality Testing Program as one of the most comprehensive in the nation.

Delaware attracts more than 7 million visitors each year, many of them drawn to the state’s scenic Atlantic beaches. According to a recent report, The Contribution of the Coastal Economy to the State of Delaware, by Delaware Sea Grant College Program at the University of Delaware, the state’s coastal economy has a significant impact on Delaware’s overall economy – generating almost $7 billion annually.

Delaware ranked first out of 30 states for cleanest water quality overall. The NRDC report cited Delaware State Park beaches (Cape Henlopen, Delaware Seashore and Fenwick Island) and the state’s Atlantic community beaches (Rehoboth, Dewey, Bethany, South Bethany, and Fenwick Island) for having excellent swimming water quality, with only a single swimming advisory (of less than 24 hours) issued among all those beaches in 2012.

About 50 ponies from the southern end of Assateague Island are herded into a southern corral. About 100 ponies reside a little further north on the Assateague Island. The northern herd is corralled temporarily before being led down the beach to the main corral.

On Monday, July 25th, 2011, the Saltwater Cowboys moved the ponies down the beach in a light rain. The roundup went well with the ponies making it safely to the southern corral.

July 4th 2011- Boating Safety

Every year, prior to the 4th of July and other major boating holidays, the U.S. Coast Guard urges boaters and beachgoers to be safe and prepared for the holiday weekend.

Being educated about safe boating could save a life. Most boating fatalities occur when the boat operator has not completed a boating safety education course. Courses cover many aspects of boating safety, from boat handling to reading the weather.

The Coast Guard also urges boaters to obtain a free vessel safety check, which is conducted by the Coast Guard Auxiliary before heading out on the water. Vessel safety checks are courtesy examinations of your vessel, verifying the presence and condition of certain safety equipment required by state and federal regulations.
