12 Birds of Tobago

Tobago boasts some of the bird world’s most incredible representatives – a mixture of South America and the Caribbean with seasonal migrants from as far as the Arctic Circle. Coincidental confluences of southward migration and the Atlantic hurricane season bring to Tobago some Europeans as well. Exciting rarities aside, let’s look at some of the island’s most familiar inhabitants. 

Although Red-billed Tropicbirds don’t quite look like grizzled seafarers, they spend most of their life at sea. Dainty and delicate, they touch land only to breed, preferring uninhabited and often inhospitable offshore islands for protection from predators.. Lacking sharp talons or even an aggressive personality, Red-billed Tropicbirds are extremely vulnerable to human activity on their nesting grounds such as Little To…

Beaches of Tobago

Dr Anjani Ganase checks the health of beaches around Tobago. We are fortunate, she believes, that significant areas of the edge between land and sea remain undisturbed. But we also need to be mindful of how buildings and other structures can alter beach habitats. (All photos courtesy Anjani Ganase)

Beaches are areas of dynamic interaction between the ocean and the land. Ocean current, wind and waves erode rock and coral skeletons to produce sand that washes ashore. Not all beaches are sandy. Sometimes, beaches are pebbly or composed of coral rubble. We can tell a lot about our beaches and their surroundings from the sand. The colour of the particles and the sizes tell us about the marine habitats as well as the type of rock our islands are made from. Black sand beaches are formed from the erosion of volcanic rock, while white sand beaches come from the breakdown of corals, but there are green and pink sand beaches as well.
Beaches are important unique ecosystems with a lot of marine cr…

Consider Cruise Ships

Image
Dr Anjani Ganase asks us to reflect on what is gained or lost when cruise ships come ashore to our islands.
Do cruise ships add or take away from the Caribbean? The cruise ship industry has boomed in the Caribbean over the last fifty years, transporting 500,000 passengers annually in the 1970s to over 20 million today. The increase in passengers corresponds to investments in engineering for bigger ships with better features and services. Over the years, cruise ships have increased in size at a rate of 90 feet every five years with the largest cruise ships today carrying over 6000 passengers. Cruise ships come with cinemas, sky diving simulators, rock climbing walls, wave riders and biking facilities along with the 24-hour all you can eat buffets on top of dining halls, bars and restaurants. It is more about the journey than the destinations! The majority of visitors come from the USA and Europe, and the most popular destinations are the Bahamas, Mexico and St Maarten. There is no doubt …

The Science of Sound for Reef Regeneration

Dr Anjani Ganase reviews a recent study where healthy reef sounds promote recovery and regeneration on degraded reefs
In a previous story, we discussed how noisy a coral reef is. (See https://wildtobago.blogspot.com/2019/04/the-sounds-of-life-underwater.html) The clicks and snaps of shrimp and crabs, and the grunts and the sighs of the many fish on the reef, may sound like white noise to us, but is easily deciphered by reef residents. Imagine walking through a city and hearing all the different sounds. The same way we differentiate sirens, street signals, chatter, construction, the fish can distinguish the noises on the reef.
Being able to hear these reef sounds is important for visitors navigating the reef; and very important for the recruitment of new coral and fish life to replenish stocks. Fish and coral larvae are attracted to the sounds that resemble a healthy bustling underwater reef city. Other areas that are more degraded with fewer reef residents will have limited sound cues …
