Shorebirds' crab feast creates spectacle on Delaware beaches

Posted on by

Several beaches on the shores of Delaware Bay are rendezvous places for many thousands of spawning horseshoe crabs and up to a million migrating shorebirds of several species during the high tide of the new or full moon during the latter half of May.

It is a timed annual meeting, perfected over millennia, when shorebirds migrating to breeding grounds on the Arctic tundra stop on the beaches to get fat eating horseshoe crab eggs. The horseshoe crab gatherings and hordes of shorebirds gorging on those water creatures' tiny, green eggs create some of the world's most inspiring wildlife spectacles.

Living fossils, horseshoe crabs are aquatic arachnids that have gone mostly unchanged during the last 250 million years. They lived before and during the age of dinosaurs. They inhabit estuaries and consume mollusks and worms on the bottoms of them. The largest gatherings of them on Earth come to the sandy beaches of estuaries along the western shores of the Atlantic Ocean to spawn billions of eggs in the sand, up to 100,000 per female.

When spawning, one or a few males, which are half the size of their mates, hang onto each female. As the females crawl up the beach, laying thousands of eggs in each of a series of sandy nests, she drags along the males, which fertilize the tiny eggs in each nursery as they are pulled over them.

Large, noisy flocks of laughing gulls and about 20 kinds of northbound shorebirds crowd Delaware Bay beaches to eat horseshoe crab eggs, creating exciting natural spectacles.

The black-headed laughing gulls are the most common and obvious gull species along the Atlantic Coast in summer. They breed in nearby salt marshes and eat anything edible.

When waves from Delaware Bay wash up on the beaches, these gulls stamp on the sand to make the water carry the sand away, exposing the horseshoe crab eggs that are then easy pickings for the gulls and shorebirds.

Shorebird congregations on Delaware Bay's beaches in May are the second largest concentration of their kind in the Western Hemisphere. Hordes of shorebirds, particularly semi-palmated sandpipers, ruddy turnstones, dunlin, red knots, sanderlings, least sandpipers and short-billed dowitchers, in that arbitrary order of abundance, and other kinds in lesser numbers, throng among breeding horseshoe crabs to feast on their eggs.

Those masses of feeding shorebirds often take off in sudden flight and speed over the water, blocking the view behind them. The birds turn this way and that in perfect unison in mid-air, which shows alternating flashes of brown upperparts, then white bellies, then brown, probably to confuse predators. But soon the great flocks settle on the beaches again, like pebbles tossed across the sand, and each bird immediately begins eating.

Some shorebirds that stop along Delaware Bay beaches to refuel on horseshoe crab eggs are somewhat starved after many miles of nonstop flight for up to four days.

Threat to close 50 of our favourite beaches

Fifty popular beaches around the UK are unlikely to meet water cleanliness standards

Tests under the latest European Bathing Water Directive could deem some of our favourite beaches unfit, leading to people being banned from going into the water from 2015.

The Environment Agency has warned that more than 50 popular sites around the UK are unlikely to meet water cleanliness standards.

Resorts including Blackpool in Lancashire, East Looe and Penzance in Cornwall and Lyme Regis, in Dorset, are at risk.

Other sites at Southsea in Hampshire, Hastings, East Sussex, and Walpole Bay, in Margate, Kent, could also be out of bounds to swimmers.

An Environment Agency spokesman said: If a beach does not pass the test, visitors will be told by way of a notice that bathing is not allowed or recommended in the water.

Tourism bosses said visitors will mistakenly think water quality has fallen if beaches are suddenly labelled unfit for swimming.

Beaches to be blacklisted for swimming under new EU rules

Posted on by

Among those likely to be ruled too polluted for bathing are popular resorts such as East Looe and Penzance in Cornwall, Lyme Regis in Dorset, Blackpool in Lancashire, and Southsea in Hampshire.

They have been favourite bank holiday destinations for British families for decades and the local economies rely heavily on the large numbers of visitors that the beaches attract.

Others at risk are Seaton Carew Centre beach near Hartlepool, which won a blue flag award last year, and Bembridge on the Isle of Wight, which is currently rated as having the highest standards of bathing water.

The change in regulations is likely to anger many in seaside communities who see further tightening of the regulations as unnecessary.

Since the current standards were put in place under the European Bathing Water Directive in the 1970s, much of the sewage outflow that caused pollution has been dramatically reduced.

But the new rules will leave beaches more vulnerable to water running off farmland where leakage from animal dung and silage can lead to elevated levels of harmful bacteria and from urban areas where misconnected drains can lead to pollution.

Dog fouling and bird droppings are also considered to be major sources of bacteria that can lead to beaches failing safety tests and as a result, some local authorities have resorted to banning dog owners from walking their pets on beaches in an attempt to reduce pollution from their waste.

The heavy rains and flooding during last year also resulted in the water quality in many areas falling significantly as sewers and drains overflowed and surface pollution from roads and farmland was washed into the sea.

Testing by the Marine Conservation Society showed that only 403 beaches could be classed as suitable for swimming.

However, a revised European Bathing Water Directive which is due to come into force in 2015 will require water to be twice as clean to achieve the highest standard a rating of Excellent.
