Trinidad

The next stage of my trip took me to Trinidad. Trinidad's close proximity and recent separation (11,000 years) from the South American continent gives it a similar fauna and flora and there many more species of mammal, reptile and amphibian than on Tobago. The island is 50 miles long and 37 wide, with many landscapes and habitats including mangroves, littoral and seasonal deciduous forests. On my trip I first visited its hilly northern range which rises to a little over 3000 feet, and most of which is still beautifully covered by tropical humid rainforest. Here I stayed at the world famous Asa Wright Nature Centre.

The centre has an exceptional biodiversity, with a species list for the area comprising 400 birds, 108 mammals, 55 reptiles, 25 amphibians and 617 butterflies. The first feature that greets you on arrival at the centre is  the fantastic veranda which overlooks the forested valley and has an abundance of hummingbird and fruit feeders on view. The fruit feeders attract a great diversity of species including green and purple honeycreepers, bay-headed, silver-beaked and white-lined tanager, violaceous euphonia. Plus half a dozen hummingbird species are almost always on view too.

After dinner, I joined a night walk along the entrance track to search for smaller creatures of the night. Trinidad chevron tarantulas, common whip scorpion spiders, true scorpions and several stick insect species were all surprisingly abundant. I also saw variegated gecko, polka-dot tree frog, tropical flat snake, common cat-eyed snake and a spectacular South American common coral snake and juvenile cook's tree boa. I also found the endemic yellow-throated frog (Mannophryne trinitatis) its favoured habitat of small mossy streams.

Birding the next morning I focussed on trying to find the tufted coquette which is not only incredibly beautiful but also has the title of being the second smallest bird in the world! A pair regular visit the flowering bushes below the veranda of the centre. After a short wait I managed a fantastic view of a male and more brief sighting of the female. This species is actually too small to feed from the artificial hummingbird feeders so you have to stake it out.

On a walk along one of the trails through the reserve I saw such species such as the recently split Guianan trogon, channel-billed toucan, lineated woodpecker, white-bearded and golden-headed manakin, bearded bellbird and bay-headed tanager.

My group also visited the Dunston Cave, (actually a gorge) home of the most accessible colony of oilbirds in the world. Oilbirds are the only nocturnal, fruit-eating birds in the world and use a combination of echolocation, a powerful sense of smell and super-sensitive vision to locate fruit bearing trees at night. We were very privileged to see these mysterious birds at their roost.

From Asa Wright we moved south to visit Tamana Bat Cave. The impressive cave systems on Tamana Hill are home to an estimated 500,000 to 3 million bats of 13 species. Entering the caves is a remarkable experience but even more spectacular is watching the emergence of thousands of the bats at dusk.

While in central Trinidad we also paid a visit to Matura beach one night, to watch leatherback turtles laying their eggs. Matura beach is the second most important nesting site in Trinidad for leatherbacks. The rural village of Matura previously received most of its income from fishing and agriculture, but in recent years these industries have been in decline while turtle watching tourism has been on the rise. This has helped boost the income for the village but with increased visitor numbers it has also caused some problems with disturbance of the turtles. There are now regulations in place and an excellent team of local volunteer rangers to enforce them. Watching an enormous female leatherback (they can grow to be as large as a small mini) laying her eggs, and then creating a decoy nest for the predators to find in the morning was fascinating and will live in my memory forever.

No trip to Trinidad would be complete without visiting Caroni swamp in the centre of the country. Here we watched hundreds of scarlet ibis coming to roost in the mangrove islands of the Caroni bird sanctuary. I was equally as excited about the impressive Cook's tree boa we found saw coiled up above our heads.

  1. Hi Ian, fabulous pictures, great to see you promoting the wonderful bats, snakes, reptiles and other invertebrates there are to enjoy out there, as well as the stonking birds!
    Best wishes, Neil

  2. Hi Neil, Thanks for your comment, yes I always enjoy promoting these groups more as they are so undervalued! I saw more snakes in Guyana in particular, than anywhere I have been before. One night we saw 6 different Amazon tree boas in just 30 minutes! Incredible!

    Let me know on Facebook (or email) how you got on in Borneo, really looking forward to hearing about it!

    Cheers,

    Ian
