One of Bermuda's avian icons, the Longtail, or White-tailed Tropicbird, is notable for its stunning white tail. Native to the Island, you'll commonly see the Longtail on souvenirs, jewellery, collectable items and more. Their appearance is a celebrated event that, to many, signifies the arrival of spring. Read on to learn more about this fascinating species.

 

Appearance

 

Alongside their long white tail feather, the body of the Longtail features distinctive black markings along their wings and around their eyes. Their bills are yellow-orange in colour and their small feet make it difficult for them to walk on land. Fully grown, an average Longtail is up to 80cm long with a wing span of up to 95cm.

 

Nesting and Mating

 

Longtails arrive on Island between April and October, nesting in holes and crevices along the shore. Females lay a single egg. Their mating ritual sees males and females flying together, both in pairs and small groups; they're often seen touching the tips of their tail feathers together. They search for nesting sites in flight and often choose the Castle Harbour Islands.

 

Reddish-purple eggs are typically laid in April, hatching in late May. Chicks have a fledgling period of approximately 65 days, after which they take to the sea between late July and early August. Longtails spend the winter season abroad, out of sight of land.

 

Diet

 

These birds feast far out from shore on fish and squid, often diving deep into the ocean to retrieve their catch.

 

Conservation

 

Today, Longtail habitat in Bermuda is threatened by coastline development, strong waves, human disturbance, predation, pollution and hurricane damage. Numbers have declined in recent decades from an estimated 3,000 nesting pairs in the late 1970s to approximately 2,000 to 3,000 single breeding birds.

 

In the late 1990s, Bermuda provided alternative nesting sites, or 'igloos,' for the birds. Made of roofing material and well insulated, these sites provide security, shelter from the sun and camouflage. There are over 30 Longtail igloos located on Nonsuch Island that are rather well-received. In 2012, the Bermuda Department of Conservation created artificial nests in coastal areas with promising results.

 

The Bermuda Audobon Society (BAS) offers nest boxes for purchase for $120.00, which can be secured to cliff tops and ledges, terraces, sea walls and more. Simple to install, they are made of cement-coated styrofoam. They must be filled with sand, weighted by a bucket of cement and camouflaged by limestone slabs.

 

Longtails, as well as their eggs and nesting sites, are protected in Bermuda under the Protection of Birds Act and the Protected Species Act. To learn more about Longtail conservation efforts and installing an igloo, please click here.

One of the greatest attractions for tourists and divers in Bermuda are the wide range of colorful coral reefs that can be seen surrounding the island. Corals are marine invertebrates that feed on plankton, small fish, and mostly algae. Bermuda has some of the northern most reefs in the North Atlantic and many being quite large in size. Corals require temperatures between 76-85F to survive and fortunately the nearby Gulf Stream keeps the water around Bermuda warm and clean which is why the reefs in Bermuda continue to thrive.Coral secretes a chemical called Calcium Carbonate, which then takes the form of limestone forming the coral reefs. Over time when millions of corals keep adding to the limestone rocks, it forms size and shape of a massive coral reef, but the process takes many years.There are three types of Coral Reefs in Bermuda, Lagoon Reefs, Rim Reefs and Terrace Reefs. Lagoon Reefs are found in the water that immediately surrounds the island and also form in the inshore water areas. The waves are low here and the water is relatively calm. The reefs here have depths ranging from 10 – 20 meters. Due to the silt, the bottom of the ocean floor here in sandy leading to lower visibility. Corals in the Lagoon Reef area include soft corals like Sea Rods, Sea Fans and branching corals.Rim Reefs form a rim around the boundary of the lagoon water area, hence the name. They have an average depth of 2 – 10 meters and they are massive in size and usually consist of hard corals like Brain and Star corals. They have a high visibility compared to Lagoon Reefs. The North Rock, the largest reef of Bermuda is part of the Rim Reefs.Terrace Reefs, the outermost reef system and comprise mainly Brain and Star corals have extremely clear visibility.Coral Reefs are seen as an advantage for the island. They act as a barrier and protect the island against heavy wave actions and the reefs are a hot spot for various marine creatures and fish, many of which have commercial value.

For years, Bermuda has been recognized as the shipwreck capital of the Atlantic Ocean. The island itself owes its establishment to settlers stranded from a shipwreck – The Sea Venture wrecked in 1609. It was once called the “isle of Devils” for a good reason, the deceptive and treacherous reefs around the island have led to many ships sinking.Triton Shipwreck was a ship purposely scuttled in 1988 off the coast of Bermuda, approximately 7 miles off the southwest side, to become a tourist attraction and professional diving site. Before her sinking, great care was taken in order to make sure it was safe for the divers.Elda Ship Wreck was an American yacht designed by Philip L. Rhodes and built in 1937 by Anderson and Combs in New Haven, Connecticut. Elda was 46 feet long and had an eleven-foot beam and based out of Maryland, on Gibson Island. She was wrecked in 1956 during the Newport to Bermuda race and now rests in shallow water close to the Eagle wreck.The Ramona, a large Canadian yacht, sunk on December 2nd, 1967 after running aground on a reef. The crew of 10 abandoned the ship after the distress signals went unnoticed. Rescuers rushed to the site after the wreck was spotted in the early hours of December 3rd. Unfortunately, only five of the crew survived. They had hoped to restore the damage of the boat but the damage was too extensive and costly for them to repair. The boat was then stripped and taken to a site off the north shore of the Royal Naval Dockyard and sunk in 60 feet of water.Hermes is one of Bermuda’s most popular shipwrecks because it remains fully unscathed. The vessel was thoroughly cleaned and made dive safe before its final voyage in 1985. Hermes lies one mile offshore at Horseshoe Bay and sits upright in 80 feet of water with her mast pointing towards the surface. The visibility of the wreck is exceptionally clear and a dive attraction to many. The white sand bottom reflects sunlight and helps illuminate the dark shadows normally found around shipwrecks. The marine life in and around the wreck includes many Sergeant Majors and Damsel Fish and even possibly schools of Barracuda’s.The King Shipwreck was the first vessel to be scuttled in Bermuda as a dive site and artificial reef. The King sits intact in 65 feet of water, half a mile off the south shore. She lays with her stern in the sand and her bow on a coral bottom. Her success of attracting marine life has attracted other ships to be scuttled around her, such as the Hermes and the ferry Triton. The King was a diesel-powered Navy tugboat built in 1941 and towards the end of her days she was converted into a dive boat owned by Gary Lamb.
