Palm Chat (Dulus Dominicus)
|
Woodpecker (Campephilus Imperialis) Its diet consists of insects, worms and larvae. It spends its days pecking on the trunks of trees and often can be found carving holes in the sides of wooden houses and clay walls. During the summer, it scavenges along the ground, looking for worms and larvae The Woodpecker is considered an endangered species. In the Dominican Republic, it can be found in the provinces of Santo Domingo, San Cristóbal, Sal Pedro de Macorís, San Juan de la Maguana and La Vega.

Hummingbird (Trochilidae) They feed on the nectar of red and orange plants to obtain calories and also on little insects to obtain proteins. This high-energy content diet, mostly comprising simple sugars, allows for their rapid-moving flight habits. Males attract mates by singing and showing off their iridescent plumage and dramatic display flights. During the gestation period, females build nests, using spider webs, cotton, lichen and moss in low-lying bushes. Clutch size is two and incubation usually lasts 14 to 19 days. Females feed their young for three or four weeks, flying to the nest up to 140 times a day.
|
Parrot (Myiopsitta monachus) Their gait is unique and amusing. If they need to climb a tree trunk or scale a branch, parrots use their beaks as well as their feet, which contain strong claws. Parrots are in danger of extinction and it is prohibited to capture or hunt them. They can be found in the National district and the provinces of Santo Domingo, Santiago, La Altagracia, Pedernales and San Juan de la Maguana.

Sea Gull There are 47 Sea Gull species, some of which are migratory. They are found throughout the world, except in deserts and tropical rainforest, the Central Pacific islands and most of Antarctica. In the Dominican Republic, they can be found in the provinces of Barahona, El Seybo, La Altagracia, María Trinidad Sánchez and Santo Domingo. Their diet consists of fish, carrion, bird eggs, insects, earthworms, and trash. They ground nesting birds and reproduce in colonies on the flat portions of beaches or on riverbanks. They usually lay two or three spotted eggs at a time, and the incubation period lasts between 20 and 30 days. Sea Gulls can live up to 40 years in captivity and up to 36 years in the wild. The Sea Gull is able to survive at the expense of other species. Their scavenging behavior can have an effect on the ecology of urban settings. Airports (as well as their garbage dumps) attract numerous amounts of these birds, putting air traffic at risk.

Flamingo (Phoenicopterus ruber ruber) Flamingos eat seeds, algae, mollusk larvae, crustacean, creatures from the Gastropoda family and other organic material. Flamingos derive their pink color from a diet rich in brine shrimp. They are also oviparous. Flamingo clutches usually consist of one egg. The incubation period lasts 28 to 32 days and is carried out by both parents. Flamingos do not nest every year. Flamingos are wading birds and reproduce in shallow waters or in small islands in shallow ponds or salty water. Babies feed off food that is regurgitated by their parents during the first 75 days of life. Flamingos reach sexual maturity between the ages of two and three years. In the wild, they have been known to reach a maximum of 27 years of age, while in captivity they can live up to 50 years. Flamingos are gregarious birds that perform their daily activities in groups. They can be found in muddy areas, coastal lakes, and estuaries. In the Dominican Republic, Flamingos live in the provinces of Barouco, Independencia and Pedernales.

Manatee (Trichechus Manatus) Manatees struggle to stay warm, but their cylindrical bodies help them to preserve their body heat. They have a slow metabolism, which can cause them to get sick in cold water. The majority of Manatees live in warm tropical waters, but those that live in Florida live in cold sub-tropical waters in the winter. They are able to survive under these conditions because they seek out warm springs in the coastal rivers. Manatees are dependent on oxygen, and therefore must rise periodically to the surface to breathe. They do not have front teeth; they only have molars. Their mouth and teeth are have evolved to accommodate an herbivorous diet. They are normally solitary, but when the female is ready to reproduce, several males will surround her and form a group. The gestation period lasts one year, and females give birth every three to five years. Manatees live in the Antilles, the Amazon and Western Africa. In the Dominican Republic, they can be found in the provinces of Barahona, María Trinidad Sánchez, Montecristi and Samaná.
|
Dolphin In the wild, it lives in temperate waters and groups together in herds that can reach numbers in the hundreds; these herds of Dolphins often tag alongside boats, doing somersaults in the air, creating a natural attraction that generates many a sympathetic observer.
|
Humpback Whale (Megaptera Novaeangliae) The Humpback Whale lives in groups. They migrate each year to tropical waters for reproduction and spend their summers in temperate and polar waters for feeding. The males are known for their whale “song,” which can last up to 30 minutes and which are highly complex. A whale’s maximum swimming speed is approximately 27 kilometers per hour. Each year, between December and April, some 3,000 Humpback Whales, in search of warm waters, travel from the North Atlantic to the Samana Bay and the Banco de Plata to reproduce.
|
Crab All Crabs are benthic, or bottom-dwelling, creatures. Only some species (the Portunidae species) have developed a secondary nectonic habit, which means they are able to swim in between the water’s current. There are more than 4,000 species of animals that are or could be called Crabs. The majority live near or in the water (rivers or oceans), although only some travel to the water to reproduce. Crabs are not usually known for being swimmers, but rather move around the floor of the water with their claws, and in many cases they are able to travel out of the water and even climb Palm trees at times.
|
Hawksbill Sea Turtle (Eretmochelys imbricada) They are omnivorous. After mating, the Hawksbill Sea Turtle travels to the beach to build nests where they can lay up to 180 eggs. Due to predators that hunt small turtles and eat their eggs, few Hawksbill Sea Turtles survive into their adult years. The Hawksbill Sea Turtle can swim for long periods of time without rising to the surface to breathe. Their habitat is primarily limited to coral reefs, and they prefer warm tropical waters. They are distributed among the Atlantic, Pacific and Indic oceans and can be found in the following provinces of the Dominican Republic: La Altagracia, Montecristi, Pedernales and Puerto Plata. This endangered animal can live between 30 to 50 years. Their slow movement makes them an easy prey and they therefore have a low survival rate.
|
American Crocodile (Crocodylus acutus) The American Crocodile is more aggressive than the American Alligator. Even the babies are dangerous. This species does not feed on humans, as is the case with its relative the Australian Saltwater Crocodile. In southern Florida, an average clutch of 38 eggs. It is possible that more than one female lays her eggs in the same nest.
|
Iguana The Iguana reaches sexual maturity at 16 months, but are not considered adults until 18 months, when they measure 21 centimeters long. They are both herbivores and omnivores. Iguanas lay many eggs at a time (about 50), in holes in the ground called burrows, which they form during the month of February. They have very short legs and five fingers on each foot, which have very sharp claws. Their tail is long and slender. Their skin is rough, with a set of pointy scales along the iguana’s back. On their head, Iguanas have what appears to be a fan on their throat; males and a dorsal spine, which the males use to mark their territory. They primarily live in the Americas and in humid regions. In the Dominican Republic, they can be found in the following provinces: Azua, Baoruco, La Altagracia, Pedernales and Peravia.
|
Solenodon The female can have two litters per year of one to three babies. Normally, the babies live until two years because the mother only has two teats. The babies are nursed for about 75 days, although at times their young remain even when another litter is born. Solenodon are not immune to their own venom: deaths following fights and injuries among Solenodon have been observed. In moments of excitement it may grunt like a pig or give bird-like cries. However, when pursued, it remains motionless and hides its head, which makes it easy to capture it. The Solenodon eats a variety of animal and vegetative material. It tends toward nocturnal behavior. During the day it hides itself in trees, hollowed-out trunks or caves. It is a clumsy mover with no agility in avoiding enemies and lacking a good means of defense. As a result, when dogs and cats where introduced onto the island, the Solenodon’s future was seen as threatened. They are now in danger of extinction. Nowadays, it is likely that they are only found in two places in the Dominican Republic: in the Eastern and Jaragua National Parks.

Bat About 70% of Bats are insectivores. Most of the rest feed on fruits, nectar and pollen; some are carnivores (they eat fish, small birds and mammals); three species sustain themselves with blood. The Bat provides many benefits to the ecosystem, like the pollination of flowers, the spreading of seeds, and the control of plagues; however, due to unfamiliarity, superstitions and myths, Bats are considered harmful. They live in the following provinces: Santo Domingo, Samaná, María Trinidad Sánchez, Pedernales and Santiago.
