The limpkin is an odd bird that looks like a large rail, but is skeletally closer to the cranes. Like the Old World vultures, they are scavengers. They were formerly classified as tanagers but were placed in their own family in 2017. They have long strong legs with powerful talons. Kingfishers are medium-sized birds with large heads, long pointed bills, short legs, and stubby tails. They eat small prey such as insects and lizards.
This is a list of the bird species recorded in the archipelago of Puerto Rico which consists of the main island of Puerto Rico, two island municipalities off the east coast (Vieques and Culebra), three uninhabited islands off the west coast (Mona, Monito and Desecheo) and more than 125 smaller cays and islands. The avifauna of Puerto Rico included a total of 377 species as of December 2019, according to Bird Checklists of the World. Seventeen species are endemic. Finches are seed-eating passerine birds, that are small to moderately large and have a strong beak, usually conical and in some species very large.
Birds of Puerto Rico provides a Check list of the birds of Puerto Rico. The Thrushes are a group of passerine birds that occur mainly but not exclusively in the Old World. The New World vultures are not closely related to Old World vultures, but superficially resemble them because of convergent evolution.
Order: Passeriformes Family: Tyrannidae. Order: Podicipediformes Family: Podicipedidae.
Order: Cathartiformes Family: Cathartidae. They are typically gray or white, often with black markings on the head or wings. The majority of these species eat small invertebrates picked out of the mud or soil.
Order: Charadriiformes Family: Charadriidae. Order: Passeriformes Family: Fringillidae. Order: Pelecaniformes Family: Pelecanidae. In size they range from 8 cm (3.1 in) to 1 m (3.3 ft) in length. Tropicbirds are slender white birds of tropical oceans with exceptionally long central tail feathers.
Though the members of this family are similar in many respects to the southern storm-petrels, including their general appearance and habits, there are enough genetic differences to warrant their placement in a separate family.
[2] For example, a 2018 study on introduced Psittacidae on the island found at least 46 species present, of which 24% are only found in the pet trade (captivity), 48% have been observed in the wild (but are not known to be breeding), and 28% are established (naturalized) and know to have bred or are currently breeding. Order: Caprimulgiformes Family: Caprimulgidae. The members of this small family are native to the Greater Antilles. As a family they are omnivorous, but individual species specialize in eating fruits, seeds, insects, or other types of food. They are large, black, or black-and-white, with long wings and deeply forked tails. Most species have strong legs and long toes which are well adapted to soft uneven surfaces. Many parrots are vividly colored, and some are multi-colored. © 2019 SOCIEDAD ORNITOLÓGICA PUERTORRIQUEÑA, INC.
1:19. The icterids are a group of small to medium-sized, often colorful passerine birds restricted to the New World and include the grackles, New World blackbirds, and New World orioles. These are nocturnal insectivores which lack the bristles around the mouth found in the true nightjars.
