Owl Monkeys
Owls are birds from the order Strigiformes (), which includes over 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight. Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl. Owls are divided into two families: the true (or typical) owl family, Strigidae, and the barn owl and bay owl family, Tytonidae. Owls hunt mostly small mammals, insects, and other birds, although a few species specialize in hunting fish. They are found in all regions of the Earth except the polar ice caps and some remote islands. A group of owls is called a "parliament". Anatomy Owls possess large, forward-facing eyes and ear-holes, a hawk-like beak, a flat face, and usually a conspicuous circle of feathers, a facial disc, around each eye. The feathers making up this disc can be adjusted to sharply focus sounds from varying di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Paleocene
The Thanetian is, in the International Commission on Stratigraphy, ICS Geologic timescale, the latest age (geology), age or uppermost stage (stratigraphy), stratigraphic stage of the Paleocene epoch (geology), Epoch or series (stratigraphy), Series. It spans the time between . The Thanetian is preceded by the Selandian Age and followed by the Ypresian Age (part of the Eocene). The Thanetian is sometimes referred to as the Late Paleocene. Stratigraphic definition The Thanetian was established by Switzerland, Swiss geologist Eugène Renevier in 1873. The Thanetian is named after the Thanet Formation, the oldest Cenozoic deposit of the London Basin, which was first identified in the area of Kent (southern England) known as the Isle of Thanet. The base of the Thanetian Stage is laid at the base of magnetic chronozone C26n. The references profile (Global Boundary Stratotype Section and Point) is in the Zumaia section (43° 18'N, 2° 16'W) at the beach of Itzurun, Pais Vasco, northern ...

Claw
A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). Some invertebrates such as beetles and spiders have somewhat similar fine, hooked structures at the end of the leg or Arthropod leg, tarsus for gripping a surface as they walk. The pincers of crabs, lobsters and scorpions, more formally known as their chelae, are sometimes called claws. A true claw is made of a hard protein called keratin. Claws are used to catch and hold prey in carnivorous mammals such as cats and dogs, but may also be used for such purposes as digging, climbing trees, self-defense and Personal grooming, grooming, in those and other species. Similar appendages that are flat and do not come to a sharp point are called nail (anatomy), nails instead. Claw-like projections that do not form at the end of digits but spring from other parts of the foot are properly named Spur (zoology), spurs. Tetrapods In tetrapods, claws are made of keratin and ...

Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for pecking, grasping, and holding (in probing for food, eating, manipulating and carrying objects, killing prey, or fighting), preening, courtship, and feeding young. The terms ''beak'' and '' rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, rhynchosaurs, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a bill-like structure), sirens, pufferfish, billfishes, and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections–the upper and lower mandibles–are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawk
Hawks are birds of prey of the family Accipitridae. They are very widely distributed and are found on all continents, except Antarctica. The subfamily Accipitrinae includes goshawks, sparrowhawks, sharp-shinned hawks, and others. This subfamily are mainly woodland birds with short broad wings, long tails, and high visual acuity. They hunt by dashing suddenly from a concealed perch. In America, members of the '' Buteo'' group are also called hawks, though birds of this group are called buzzards in other parts of the world. Generally, buteos have broad wings and sturdy builds. They are relatively larger-winged and shorter-tailed than accipiters, and fly further distances in open areas. Buteos descend or pounce on their prey rather than engaging in fast, horizontal pursuit. The terms ''accipitrine hawk'' and ''buteonine hawk'' are used to distinguish between the types in regions where ''hawk'' applies to both. The term ''"true hawk"'' is sometimes used for the accipitrin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Athene Cuniculariaa
Athena or Athene, often given the epithet Pallas, is an ancient Greek goddess associated with wisdom, warfare, and handicraft who was later syncretized with the Roman goddess Minerva. Athena was regarded as the patron and protectress of various cities across Greece, particularly the city of Athens, from which she most likely received her name. The Parthenon on the Acropolis of Athens is dedicated to her. Her major symbols include owls, olive trees, snakes, and the Gorgoneion. In art, she is generally depicted wearing a helmet and holding a spear. From her origin as an Aegean palace goddess, Athena was closely associated with the city. She was known as ''Polias'' and ''Poliouchos'' (both derived from ''polis'', meaning "city-state"), and her temples were usually located atop the fortified acropolis in the central part of the city. The Parthenon on the Athenian Acropolis is dedicated to her, along with numerous other temples and monuments. As the patron of craft and w ...

Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

Bay Owl
The bay owls (''Phodilus'') are a genus of Old World owls in the family Tytonidae. The defining characteristics of bay owls are their smaller bodies, in comparison to the barn owls ''Tyto'' in the same family, and their U- or V-shaped faces. These owls can be found across southern Asia from southern India and Sri Lanka to Indonesia within forest and grassland ecosystems. Taxonomy and systematics The genus ''Phodilus'' was described by the French zoologist Isidore Geoffroy Saint-Hilaire in 1830. Most taxonomists include two extant species in the genus; a third formerly included has now been transferred to ''Tyto''. The name is from the Ancient Greek ''phōs'' for "light" or "daylight" and ''deilos'' for "timid" or "cowardly". The Itombwe owl (''Tyto prigoginei'') was formerly classified in this genus as the Congo bay owl, but morphological evidence shows that it is a member of the genus ''Tyto ''Tyto'' is a genus of owls in the family Tytonidae.

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...
