Pteronotus Quadridens
The sooty mustached bat (''Pteronotus quadridens'') is a species of bat in the family Mormoopidae. It is found in Cuba, the Dominican Republic, Haiti, Jamaica, and Puerto Rico. Description Sooty mustached bat is the smallest species in the genus ''Pteronotus''. Color phases in this bat are indicators of age differences or bleaching due to high concentrations of ammonia in the roost. As a result, color ranges from grayish brown to yellowish brown with some individuals reaching an orange-brown phase. The body is completely covered in fur except for the wings and tail membrane. The length of mandible is and their forearm is less than in length. The margin above nostril is lobulated and slightly convex. Mating and reproduction Sooty mustached bats are monoesturous and uniparous most of the time with twinning rarely occurring. Based on the testicular size, mating begins in January and most females are pregnant in May. The pregnant female undergoes an increase in body mass of 3 ...

Juan Gundlach
Juan Cristóbal Gundlach (17 July 1810 in Marburg – 14 March 1896 in Havana), born Johannes Christoph Gundlach was a Cuban naturalist and taxonomist. Biography Gundlach graduated from Marburg University, where his father was professor of physics, as Doctor of Philosophy in 1837. In 1839, he left Europe to make collections on the Caribbean island of Cuba, where he lived ever since. During a short trip to Puerto Rico, at the request of Jesuit fathers to offer assistance in the creation of a zoological collection, in 1868, when revolutionary activities were beginning in Cuba as well as Puerto Rico, he met with don Tomás Blanco, according to naturalist Dr. Agustín Stahl. A friend of Carl Wilhelm Leopold Krug, who served as German Vice Consul in Mayagüez, Puerto Rico and who paid for some of Gundlach's travels, he visited Puerto Rico in 1873, leaving Havana on 4 June 1873 on the ship Manuela, arriving in Mayagüez, Puerto Rico on 13 June, staying in Puerto Rico for approximatel ...

Animal Echolocation
Echolocation, also called bio sonar, is a biological sonar used by several animal species. Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for navigation, foraging, and hunting in various environments. Echolocating animals include some mammals (most notably Laurasiatheria) and a few birds, especially some bat species and odontocetes (toothed whales and dolphins), but also in simpler forms in other groups such as shrews, and two cave-dwelling bird groups, the so-called cave swiftlets in the genus ''Aerodramus'' (formerly ''Collocalia'') and the unrelated oilbird ''Steatornis caripensis''. Early research The term ''echolocation'' was coined in 1938 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. As Griffin described in his book, the 18th century I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1840
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together wi ...

Mammals Of Puerto Rico
The fauna of Puerto Rico is similar to other island archipelago faunas, with high endemism, and low, skewed taxonomic diversity. Bats are the only extant native terrestrial mammals in Puerto Rico. All other terrestrial mammals in the area were introduced by humans, and include species such as cats, goats, sheep, the small Indian mongoose, and escaped monkeys. Marine mammals include dolphins, manatees, and whales. Of the 349 bird species, about 120 breed in the archipelago, and 47.5% are accidental or rare. The most recognizable and famous animal of Puerto Rico is probably the common coquí, a small endemic frog, and one of the 86 species that constitute Puerto Rico's herpetofauna. Some native freshwater fish inhabit Puerto Rico, but some species, introduced by humans, have established populations in reservoirs and rivers. The low richness-high diversity pattern is also apparent among invertebrates, which constitutes most of the archipelago's fauna. The arrival of the first peopl ...

Merlin
Merlin ( cy, Myrddin, kw, Marzhin, br, Merzhin) is a mythical figure prominently featured in the legend of King Arthur and best known as a mage, with several other main roles. His usual depiction, based on an amalgamation of historic and legendary figures, was introduced by the 12th-century British author Geoffrey of Monmouth. It is believed that Geoffrey combined earlier tales of Myrddin and Ambrosius, two legendary Briton prophets with no connection to Arthur, to form the composite figure called Merlinus Ambrosius ( cy, Myrddin Emrys, br, Merzhin Ambroaz). Geoffrey's rendering of the character became immediately popular, especially in Wales. Later writers in France and elsewhere expanded the account to produce a fuller image, creating one of the most important figures in the imagination and literature of the Middle Ages. Merlin's traditional biography casts him as an often-mad being born of a mortal woman, sired by an incubus, from whom he inherits his supernatural powe ...

Red-tailed Hawk
The red-tailed hawk (''Buteo jamaicensis'') is a bird of prey that breeds throughout most of North America, from the interior of Alaska and northern Canada to as far south as Panama and the West Indies. It is one of the most common members within the genus of ''Buteo'' in North America or worldwide. The red-tailed hawk is one of three species colloquially known in the United States as the " chickenhawk", though it rarely preys on standard-sized chickens. The bird is sometimes also referred to as the red-tail for short, when the meaning is clear in context. Red-tailed hawks can acclimate to all the biomes within their range, occurring on the edges of non-ideal habitats such as dense forests and sandy deserts.Preston, C. R. (2000). ''Red-tailed Hawk''. Stackpole Books. The red-tailed hawk occupies a wide range of habitats and altitudes, including deserts, grasslands (from small meadows to the treed fringes of more extensive prairies), coniferous and deciduous forests, agricultur ...

American Kestrel
The American kestrel (''Falco sparverius''), also called the sparrow hawk, is the smallest and most common falcon in North America. It has a roughly two-to-one range in size over subspecies and sex, varying in size from about the weight of a blue jay to a mourning dove. It also ranges to South America and is a well-established species that has evolved into 17 subspecies adapted to different environments and habitats throughout the Americas. It exhibits sexual dimorphism in size (females being moderately larger) and plumage, although both sexes have a rufous back with noticeable barring. Its plumage is colorful and attractive, and juveniles are similar in plumage to adults. The American kestrel usually hunts in energy-conserving fashion by perching and scanning the ground for prey to ambush, though it also hunts from the air. It sometimes hovers in the air with rapid wing beats while homing in on prey. Its diet typically consists of grasshoppers and other insects, lizards, m ...
