Guianan Red Howler - Trinidad and Tobago

Trinidad was connected to the South American mainland during the last ice age through a land bridge. When the ice sheets receded, the water levels rose and submerged the channel. Trinidad is now separated from Venezuela by the Columbus Channel in the south and the Bocas del Dragón, the Dragon's Mouths, in the north.

Alouatta macconnelli - The Guianan red howler monkey is well known for its roaring howl, the first tactic for defending territorial claims. Their howls are common during early morning or late afternoons and prior to the beginning of rain showers. Howlers feed primarily on leaves and fruit. When the opportunity arises, they will also take on bird eggs and small invertebrates. There are three species of howler monkeys in the Americas with the Guianan red howler being native to the Guinana Shield northeastern region of South America.

Lilac-tailed Parrotlet - Trinidad and Tobago

Touit batavicus - The lilac-tailed parrotlet is a small parrot averaging about 14 centimeters in length and between 58 and 72 grams in weight. It can be found in Trinidad and Tobago and along the forested areas of French Guinea, Guyana, Suriname, and Venezuela. The lilac-tailed parrotlet prefers dense forests and nothing above 1,700 meters. It rarely comes into contact with the ground and therefore its diet is limited to what the forest canopy can offer; nectar, flowers, fruits, berries, and seeds.

The islands of Trinidad and Tobago host several mud volcanoes. The activity of a typical mud volcano usually consists of a mild surface up-welling of heated mud and saline water accompanied by methane gas bubbles. Some violent eruptions resulting in a large mass of rocks scattered over a wide area of the countryside have been recorded, but these incidents are rare. Mud volcanoes, often called mud pots, are not true igneous volcanoes because they do not produce any lava or magma.
