There are about 22 species of Grebes worldwide.
The Least Grebe (Tachybaptus dominicus) is an aquatic bird and is the smallest member of the grebe family in the Americas. Its length is between 8.3–10.6 in. Spending most of their time on water, Grebes can be found on freshwater ponds, lakes, and marshes. On one of the dams that perimeter the Trust we are very fortunate to have active, breeding Least Grebes for a couple years now.
Small and plump, with a fairly short, sharp-pointed bill and bright yellow eyes, it typically appears quite dark /sooty all over. The breeding adult is brownish grey above with a darker blackish crown and throat while the immature are paler and greyer with a black striped head and dull eyes.
Grebes have lobed toes, and are excellent swimmers and divers. Although they can run for a short distance, they are prone to falling over, since their legs are set well back on their body.
The Grebe’s diet consists of aquatic life, including small fishes, crustaceans, frogs and aquatic insects. It pursues much of its prey under water. During active feeding, it spends an average of 12 seconds beneath the surface on each dive. They also respond to danger by diving rather than flying.
Each pair builds a compact floating nest of vegetation with a variety of aquatic weeds which is anchored to rooted plants in still open water as deep as 5 ft. The female lays three to six white eggs. Both adults incubate the eggs, which hatch after 21 days. The striped young are sometimes carried on the adult’s back.

Scientific Name: Ara manilata
Family: Psittacidae (Parrots and Macaws)
An intrinsic part of the avian fauna of the Nariva Wetlands includes the endangered Blue & Gold Macaws (Ara araurauna):This species bred at the Trust has been re-introduced into the Nariva Wetlands .The population of Red-Bellied Macaws(Ara manilata) has diminished severely over recent years.
The struggle to save the viability and the ecosystem services of Trinidad & Tobago’s first RAMSAR (1993) site together with the community of small-scale rice-farmers, fishermen and farmers includes the need to conserve the high species diversity there The Forest Act of the Government of T & T declared the Nariva Wetlands as a Protected Area in 1968. Further as a result of persistent lobbying of the P-a-P Wildfowl Trust, the Nariva Wetlands was declared as an Environmentally Sensitive Area in 2006 under the EM Act.

Call loud but less raucous than that of other parrots. (Source: A Guide to the Birds of enezuela)
Used to be fairly common local resident in Trinidad in Nariva Swamp and the vicinity of Aripo Savannah, especially where the moriche palm abounds. The birds feed primarily in the early morning and evening, and at these times flocks are very conspicuous as they travel from one feeding place to another. They roost communally.
