Smooth-billed Ani
The smooth-billed ani (''Crotophaga ani'') is a bird in the cuckoo family. It is a resident breeding species from southern Florida, the Caribbean, parts of Central America, south to western Ecuador, Brazil, northern Argentina and southern Chile. It was introduced to Galápagos around the 1960s and is potentially impacting native and endemic species across the archipelago. Taxonomy The smooth-billed ani was described and illustrated in 1648 by the German naturalist Georg Marcgrave in his ''Historia Naturalis Brasiliae''. He used the name "Ani" but did not explain the origin of the word. It probably comes from the word ''Anim'' in the Tupi language which means "social bird". In 1756 the Irish physician Patrick Browne used the name ''Crotophaga'' for the species in his ''The Civil and Natural History of Jamaica''. Browne's name combines the Ancient Greek ''krotōn'' meaning "tick" with ''-phagos'' meaning "-eating". Browne wrote that the smooth-billed anis "live chiefly upon ticks a ...

Grand Cayman
Grand Cayman is the largest of the three Cayman Islands and the location of the territory's capital, George Town. In relation to the other two Cayman Islands, it is approximately 75 miles (121 km) southwest of Little Cayman and 90 miles (145 km) southwest of Cayman Brac. Geography Grand Cayman encompasses 76% of the territory's entire land mass. The island is approximately long with its widest point being wide. The elevation ranges from sea level at the beaches to above sea level on the North Side's Mastic Trail. Unlike many other Caribbean islands, Grand Cayman is for the most part, flat. This allows for more space to build as the island’s population grows. Island districts Grand Cayman Island includes five of the six districts of the Cayman Islands: Bodden Town, East End, George Town, North Side and West Bay. *Bodden Town – Founded in the 1700s, Bodden Town district comprises the central part of Grand Cayman Island, between the George Town and Nort ...

Crotophaga
The anis are the three species of birds in the genus ''Crotophaga'' of the cuckoo family. They are essentially tropical New World birds, although the range of two species just reaches the United States.Payne, R.B. (2005). ''The Cuckoos''. Oxford University Press. Unlike some cuckoos, the anis are not brood parasites, but nest communally, the cup nest being built by several pairs from 2–6 m high in a tree. A number of females lay their eggs in the nest and then share incubation and feeding. The anis are large black birds with a long tail and a deep ridged black bill. Their flight is weak and wobbly, but they run well, and usually feed on the ground. These are very gregarious species, always found in noisy groups. Anis feed on termites, large insects, and even lizards and frogs. The claim that they will remove ticks and other parasites from grazing animals has been disputed; while there is no doubt that anis follow grazing animals to catch disturbed insects and will occasi ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

Bird Nest
A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests is known as ''caliology''. Not all bird species bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Egg
Bird eggs are laid by the females and range in quantity from one (as in condors) to up to seventeen (the grey partridge). Clutch size may vary latitudinally within a species. Some birds lay eggs even when the eggs have not been fertilized; it is not uncommon for pet owners to find their lone bird nesting on a clutch of infertile eggs, which are sometimes called wind-eggs. Anatomy All bird eggs contain the following components: * The embryo is the immature developing chick * The amnion is a membrane that initially covers the embryo and eventually fills with amniotic fluid, provides the embryo with protection against shock from movement * The allantois helps the embryo obtain oxygen and handles metabolic waste * The chorion, together with the amnion, forms the amniotic sac and encloses the amnion, vitellus, and the embryo * The vitellus, or yolk, is the nutrient-bearing portion of the egg, containing most of its fat, minerals, and many of its proteins and blood vessels * The alb ...

Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...

Cursorial
A cursorial organism is one that is adapted specifically to run. An animal can be considered cursorial if it has the ability to run fast (e.g. cheetah) or if it can keep a constant speed for a long distance (high endurance). "Cursorial" is often used to categorize a certain locomotor mode, which is helpful for biologists who examine behaviors of different animals and the way they move in their environment. Cursorial adaptations can be identified by morphological characteristics (e.g. loss of lateral digits as in ungulate species), physiological characteristics, maximum speed, and how often running is used in life. There is much debate over how to define a cursorial animal specifically. The most accepted definitions include that a cursorial organism could be considered adapted to long-distance running at high speeds or has the ability to accelerate quickly over short distances. Among vertebrates, animals under 1 kg of mass are rarely considered cursorial, and cursorial behaviors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groove-billed Ani
The groove-billed ani (''Crotophaga sulcirostris'') is a tropical bird in the cuckoo family with a long tail and a large, curved beak. It is a resident species throughout most of its range, from southern Texas, central Mexico and The Bahamas, through Central America, to northern Colombia and Venezuela, and coastal Ecuador and Peru. It only retreats from the northern limits of its range in Texas and northern Mexico during winter. Taxonomy The groove-billed ani was formally described by the English naturalist William John Swainson from a specimen collected in Temascaltepec, Mexico. It still bears its original binomial name of ''Crotophaga sulcirostris''. The specific epithet combines the Latin meaning "furrow" with ''-'' meaning "-billed". The species is monotypic: no subspecies are recognised. Description The groove-billed ani is about long, and weighs . Wingspan ranges 41-46 cm (16-18 in). It is completely black, with a very long tail almost as long as its body. It has a huge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
