Slender-billed Kite
The slender-billed kite (''Helicolestes hamatus'') is a South American bird of prey in the family Accipitridae. It is found along a scattered range in forested parts of tropical northern and central South America, and far eastern Panama. The species was recategorized into and has once again been removed from the genus '' Rostrhamus.'' Description The slender-billed kite is a slaty gray kite with broad, rounded wings and a short, square tail. The species ranges from 36 to 41 centimeters in length and possesses a wingspan of 80-90 centimeters. There is no sexual plumage dimorphism within the species; however, females tend to be larger than the males, weighing between 367 and 485 grams while males weigh between 377 and 448 grams. Their characteristically sharp black beak is hooked, matched by sharp, black talons. Their eyes are yellowish, and their face and legs are orange-red. Juveniles resemble adults, but have brownish eyes and three narrow white bands in the tail. Both gende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Snail Kite
The snail kite (''Rostrhamus sociabilis'') is a bird of prey within the family Accipitridae, which also includes the eagles, hawks, and Old World vultures. Its relative, the slender-billed kite, is now again placed in ''Helicolestes'', making the genus ''Rostrhamus'' monotypic. Usually, it is placed in the milvine kites, but the validity of that grouping is under investigation. Description Snail kites are long with a wingspan. They weigh from . There is very limited sexual dimorphism, with the female averaging only 3% larger than the male. They have long, broad, and rounded wings, which measure each. Its tail is long, at , with a white rump and undertail coverts. The dark, deeply hooked beak, measuring is an adaptation to its diet. The tarsus is relatively long as well, measuring . The adult male has dark blue-gray plumage with darker flight feathers. The legs and cere are red. The adult female has dark brown upperparts and heavily streaked pale underparts. She has a whiti ...

Birds Of The Amazon Basin
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Kites (birds)
A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces. A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. Some kite designs don’t need a bridle; box kites can have a single attachment point. A kite may have fixed or moving anchors that can balance the kite. The name is derived from kite, the hovering bird of prey. The lift that sustains the kite in flight is generated when air moves around the kite's surface, producing low pressure above and high pressure below the wings. The interaction with the wind also generates horizontal drag along the direction of the wind. The resultant force vector from the lift and drag force components is opposed by the tension of one or more of the lines or tethers to which the kite is attached. The anchor point of the kite line may be static or moving (e.g., the towing of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operculum (gastropod)
The operculum (; ) is a corneous or calcareous anatomical structure like a trapdoor that exists in many (but not all) groups of sea snails and freshwater snails, and also in a few groups of land snails; the structure is found in some marine and freshwater gastropods, and in a minority of terrestrial gastropods, including the families Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc. The operculum is attached to the upper surface of the foot and in its most complete state, it serves as a sort of "trapdoor" to close the aperture of the shell when the soft parts of the animal are retracted. The shape of the operculum varies greatly from one family of gastropods to another. It is fairly often circular, or more or less oval in shape. In species where the operculum fits snugly, its outline corresponds exactly to the shape of the aperture of the shell and it serves to seal the entrance of the shell. Many families have opercula that are reduced in size, and which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pomacea
''Pomacea'' is a genus of freshwater snails with gills and an operculum, aquatic gastropod mollusks in the family Ampullariidae, the apple snails. The genus is native to the Americas; most species in this genus are restricted to South America. in the aquarium trade these snails are sometimes called ''Pomacea'' or incorrectly ''Ampullarius'', and in English as "olormystery snail" or "apple snail". Some species have been introduced outside their native range and are considered invasive because of their voracious appetite for plants. Because of this, imports involving this genus are restricted in some regions (including the United States) and are entirely banned in others (including the EU).Dawes, J. (14 January 2013). International Waters: EU Finally Bans Apple Snail Imports.'' Retrieved 4 June 2014 Species Species in the genus ''Pomacea'' include: subgenus ''Effusa'' Jousseaume, 1889 * ''Pomacea baeri'' (Dautzenberg, 1902) * ''Pomacea glauca'' (Linné, 1758) * ''Pomacea q ...
