Black-faced Grosbeak
The black-faced grosbeak (''Caryothraustes poliogaster'') is a large seed-eating bird in the cardinal family (Cardinalidae), which is a resident breeding species from south-eastern Mexico to eastern Panama. Description The adult black-faced grosbeak is 16.5 cm long, weighs 36 g, and has a heavy, mainly black, bill. It has a black face, yellow head, neck and breast, and olive back, wings and tail. The rump and belly are grey. Immatures are duller and have duskier face markings. The vocalisations include sharp ''chip'' or ''tweet'' calls, buzzes and whistles, and the song is a musical whistled ''cher chi weet, cher chir weet, cher chi chuweet''. Diet and behavior The black-faced grosbeak forages in shrubs or trees for beetles, caterpillars and other insects, and also eats fruit such as those of gumbo-limboFoster (2007) (''Bursera simaruba''), seeds, and nectar taken from flowers or epiphyte bracts. It forms noisy flocks of up to 20 birds, and is often in mixed-species f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bernard Du Bus De Gisignies
Bernard Amé Léonard du Bus de Gisignies (21 June 1808 in Saint-Josse-ten-Noode – 6 July 1874 in Bad Ems) was a Dutch nobleman and later on a Belgium, Belgian politician, ornithologist and paleontologist. He was the second son of Leonard Pierre Joseph du Bus de Gisignies. He married ''Petronilla Truyts'' on 19 May 1845, together they had two children; Viscount Bernard Daniel (Saint-Josse-ten-Noode, 7 October 1832 - City of Brussels, Brussels, 17 February 1917) and Viscount Chretien (Saint-Josse-ten-Noode, 4 November 1845 - Jabbeke, 3 July 1883). He studied law at the State University of Louvain, but soon became more interested in ornithology. In 1835 he presented a manuscript to the The Royal Academies for Science and the Arts of Belgium, Royal Academy of Belgium in which described the bird ''Leptorhynchus pectoralis'' (the banded stilt). He was a member of parliament for Soignies. He became the first director of the Royal Belgian Institute of Natural Sciences in 1846. On ...

Honeycreeper
The typical honeycreepers form a genus ''Cyanerpes'' of small birds in the tanager family Thraupidae. They are found in the tropical New World from Mexico south to Brazil. They occur in the forest canopy, and, as the name implies, they are specialist nectar feeders with long curved bills. The four ''Cyanerpes'' species have colourful legs, long wings and a short tail. The males are typically glossy purple-blue and the females greenish. Taxonomy and species list The genus ''Cyanerpes'' was introduced in 1899 by the American ornithologist Harry C. Oberholser with the red-legged honeycreeper as the type species. The name combines the Ancient Greek ''kuanos'' meaning "dark-blue" and ''herpēs'' meaning "creeper". There are two other tanagers with honeycreeper in their common name: the green honeycreeper in the monospecific genus ''Chlorophanes'' and the golden-collared honeycreeper in the monospecific genus ''Iridophanes''. These two species are sister taxa and belong to the subf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Belize
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 ...

Caryothraustes
''Caryothraustes'' is a genus of grosbeak in the family Cardinalidae. The genus was introduced by the German naturalist Ludwig Reichenbach in 1850. The type species was subsequently designated as the yellow-green grosbeak. The name ''Caryothraustes'' combines the Ancient Greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic p ... words ''karuon'' "nut" and ''thraustēs'' "breaker".

Arecaceae
The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history. Many common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their importance as ...

Bromeliad
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, ''Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss (''Tillandsia usneoides''), and terrestrial species, such as the pineapple (''Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte ''Tillandsia'' species that gath ...

Clearing (forest)
In the most general sense, a glade or clearing is an open area within a forest. Glades are often grassy meadows under the canopy of deciduous trees such as red alder or quaking aspen in western North America. They also represent openings in forests where local conditions such as avalanches, poor soils, or fire damage have created semipermanent clearings. They are very important to herbivorous animals, such as deer and elk, for forage and denning activities. Sometimes the word is used in a looser sense, as in the treeless wetlands of the Everglades of Florida. In the central United States, calcareous glades occur with rocky, prairie-like habitats in areas of shallow soil. Glades are characterized by unique plant and animal communities that are adapted to harsh and dry conditions. See also *Treefall gap A treefall gap is a distinguishable hole in the canopy of a forest with vertical sides extending through all levels down to an average height of above ground. These holes o ...

Woodland Edge
A woodland edge or forest edge is the transition zone (ecotone) from an area of woodland or forest to fields or other open spaces. Certain species of plants and animals are adapted to the forest edge, and these species are often more familiar to humans than species only found deeper within forests. A classic example of a forest edge species is the white-tailed deer in North America. The woodland edge on maps On topographic maps woods and forests are generally depicted in a soft green colour. Their edges are - like other features - usually determined from aerial photographs, but sometimes also by terrestrial survey. However, they only represent a snapshot in time because almost all woods have a tendency to spread or to gradually fill clearings. In addition, working out the exact edge of the wood or forest may be difficult where it transitions into scrub or bushes or the trees thin out slowly. Differences of opinion here often involved several tens of metres. In addition, many car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New World Warbler
The New World warblers or wood-warblers are a group of small, often colorful, passerine birds that make up the family Parulidae and are restricted to the New World. They are not closely related to Old World warblers or Australian warblers. Most are arboreal, but some, like the ovenbird and the two waterthrushes, are primarily terrestrial. Most members of this family are insectivores. This group likely originated in northern Central America, where the greatest number of species and diversity between them is found. From there, they spread north during the interglacial periods, mainly as migrants, returning to the ancestral region in winter. Two genera, '' Myioborus'' and ''Basileuterus'', seem to have colonized South America early, perhaps before the two continents were linked, and together constitute most warbler species of that region. The scientific name for the family, Parulidae, originates from the fact that Linnaeus in 1758 named the northern parula as a tit, ''Parus amer ...

Tanager
The tanagers (singular ) comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropical birds. Traditionally, the family contained around 240 species of mostly brightly colored fruit-eating birds. As more of these birds were studied using modern molecular techniques, it became apparent that the traditional families were not monophyletic. ''Euphonia'' and ''Chlorophonia'', which were once considered part of the tanager family, are now treated as members of the Fringillidae, in their own subfamily (Euphoniinae). Likewise, the genera ''Piranga'' (which includes the scarlet tanager, summer tanager, and western tanager), '' Chlorothraupis'', and '' Habia'' appear to be members of the cardinal family, and have been reassigned to that family by the American Ornithological Society.
