Sea Birds on Little Tobago

Red-billed Tropicbird makes its way out to sea after attending to its chick on Little Tobago



Little Tobago is visible from the coast as one begins to near Speyside, driving from the south. With powerful binoculars, one may just be able to discern avian shapes that are not found anywhere else within Tobago or Trinidad. As the island is approached by boat, the distinctive, raking calls of Red-billed Tropicbirds fill the air, especially during the first half of the year when these graceful, angelic seabirds raise their young on lazily constructed nests on the ground. A short hike to the top of the island and you arrive at convenient and comfortable viewing platforms. At times, no optical aids are necessary as the various species of seabird jostle for space no more than twenty feet away!

These islands are among the most accessible places in the world to view Red-billed Tropicbirds, which typically nest on remote offshore islands. Each day, they fly out to sea where they grab squid and fish – flying fish is a favourite – and deliver either solid or semi-digested food, depending on the age of the chick. Both parents repeat the process innumerable times until the chick has fledged, when it will be encouraged to leave the nest and catch its own food. Each fishing trip the parent makes is a dance through the gauntlet of greedy “Man o’ Wars”.

Unlike the Tropicbirds, Magnificent Frigatebirds do not have waterproof feathers; but they too thrive on fish. To eat, these huge seabirds have perfected the art of stealing. Once a returning Red-billed Tropicbird is sighted, the Frigatebirds attack, dive-bombing the smaller bird, sometimes even pulling on its long tail-streamers to get it to release its catch. The only way to escape harassment would be to regurgitate whatever fish it is returning to the nest with.

Other seabirds also have to dodge the Magnificent Frigatebirds. Brown Boobies are relatively common around beaches all over Tobago, and are a familiar sight for many Tobagonians. The slightly less common Red-footed Booby nests on Little Tobago and the islands of St Giles. Its red feet are a field mark for conclusive identification, even though this bird comes in a few disguises – called “colour morphs.” The brown morph is wholly brown, except for the very tip of its tail, which is frosted white. The white morph is mostly white, with black flight feathers. There is an intermediate morph as well, that is brown with a white tail. All colour morphs have unmistakable red feet.

Apart from the species discussed here, sometimes a true wanderer visits our islands. There have been records in the recent past of the smaller White-tailed Tropicbird nesting among its Red-billed cousins. Also, just last year, there were a few Masked Boobies spotted – causing much excitement among the local birdwatching community. For special ecosystems such as these offshore islands, it is imperative to consistently monitor the birdlife as a valuable contribution to the worldwide knowledge base. Seabirds are generally difficult to study, given their habits of being in the open, uncharted ocean for most of the year. The only chance we have to study, or view, these birds would be when they choose to breed. This underscores the need to ensure that they have stable and secure nurseries to which they might return year after year.

Another silent colonizer of these islands in recent times is no seabird. Scaly-naped Pigeons are relatives of the feral pigeons we see in urban areas, and they are relatively common in the greater Caribbean region. Some years ago, a few intrepid individuals discovered the islands of St Giles and Little Tobago, and their population is expanding. Just a couple years ago, I saw a Scaly-naped Pigeon in Charlotteville, one of the first records of this bird on mainland Tobago.

As with any patch of forest, the more you look, the more you see. Many birds are heard long before they are seen. Bananaquits never stop chattering, and they usually provide accompaniment on the walk through Little Tobago. Listen for the “whoop” of the Trinidad Motmot, and you’ll quickly be able to find the brilliantly coloured King-of-the-woods, more than likely with its eyes already fixated on the human presence. Another bird that seems to vocalize incessantly is the Red-eyed Vireo; this bird currently holds the record for the most calls made in a single day. The subspecies found on Little Tobago is called the “Chivi Vireo”, and may soon be recognized as a separate species altogether!

Some birds do not bless us with song as others do. Nor are they coloured with various shades of yellow, green or blue. So it’s quite understandable that you might overlook the presence of a White-tailed Nightjar while on Little Tobago. These cryptic birds blend in seamlessly with their surroundings; nocturnal birds, they sleep during the day and must be able to remain unseen even while asleep. Once darkness falls it’s another story.
