Yellow-headed Blackbird
The yellow-headed blackbird (''Xanthocephalus xanthocephalus'') is a medium-sized blackbird with a yellow head. It is the only member of the genus ''Xanthocephalus''. Their scientific name derives from the Greek word for yellow, ''xanthous'', and the word for head, ''cephalus''. Description Yellow-headed blackbirds are relatively large blackbirds with large, yellow heads.Twedt, Daniel J. "Ecology of yellow-headed blackbirds." ''Ecology and Management of Blackbirds (Icteridae) in North America''. CRC Press, 2017. 43–64. They measure 8.3–10.2 in (21–26 cm) in length, with a wingspan of 16.5–17.3 in (42–44 cm) and a weight of 1.6–3.5 oz (44–100 g). Adults have a pointed bill. The adult male is mainly black with a yellow head and breast; they have a white wing patch sometimes only visible in flight. The adult female is mainly brown with a dull yellow throat and breast. Immature members of both sexes are brown with duller yellow plumage ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bird Colony
A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non- neornithine birds (Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania. Variations on colonial nesting in birds Approximately 13% of all bird species nest colonially. Nesting colonies are very common among seabirds on cliffs and islands. Nearly 95% of seabirds are colonial, leading to the usage, seabird colony, sometimes called a rookery. Many species of terns nest in colonies ...

Birds Described In 1826
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 furth ...

Fauna Of The Sonoran Desert
The Sonoran Desert () is a hot desert and ecoregion in North America that covers the northwestern Mexican states of Sonora, Baja California, and Baja California Sur, as well as part of the Southwestern United States (in Arizona and California). It is the hottest desert in Mexico. It has an area of . In phytogeography, the Sonoran Desert is within the Sonoran floristic province of the Madrean region of southwestern North America, part of the Holarctic realm of the northern Western Hemisphere. The desert contains a variety of unique endemism, endemic plants and animals, notably, the saguaro (''Carnegiea gigantea'') and Stenocereus thurberi, organ pipe cactus (''Stenocereus thurberi''). The Sonoran Desert is clearly distinct from nearby deserts (e.g., the Great Basin Desert, Great Basin, Mojave Desert, Mojave, and Chihuahuan Desert, Chihuahuan deserts) because it provides subtropical warmth in winter and two seasons of rainfall (in contrast, for example, to the Mojave's dry summers ...

Fauna Of The Lower Colorado River Valley
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and ''funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word for a book ...

Icteridae
Icterids () or New World blackbirds make up a family, the Icteridae (), of small to medium-sized, often colorful, New World passerine birds. The family contains 108 species and is divided into 30 genera. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. The species in the family vary widely in size, shape, behavior, and coloration. Etymology The name, meaning "jaundiced ones" (from the prominent yellow feathers of many species) comes from the - ''íkteros'' via the . Relationship to other species This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, Quiscalus, grackles, cowbirds, oropendolas, and cacique (bird), caciques. Despite the similar names, the first groups are only distantly related to the Old World common blackbird (a thrush (bird), thrush) or to the Old World orioles. The Icteridae are not to be confused with the Icteriidae, a family created in 2017 and consisting of one specie ...

Marsh Wren
The marsh wren (''Cistothorus palustris'') is a small North American songbird of the wren Family (biology), family. It was formerly called the long-billed marsh wren to distinguish it from the sedge wren, then known as the short-billed marsh wren. Taxonomy The marsh wren was Species description, described by the Scottish-American ornithologist Alexander Wilson (ornithologist), Alexander Wilson in 1810 and given the binomial name ''Certhia palustris''. The current genus ''Cistothorus'' was introduced by the German ornithologist Jean Cabanis in 1850. There are 15 recognised subspecies. Etymology: from Greek 'κιστος' (''cistos'', "a shrub") and 'θουρος' (''thouros'', "leaping, or running through") and Latin 'palustris' ("marshy"). Description Adults have brown upperparts with a light brown belly and flanks and a white throat and breast. The back is black with white stripes. They have a dark cap with a white line over the eyes and a short thin bill. The male's song is ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Odonata
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the '' Epiophlebia'' damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and wings folded together along body at rest. Adult odonates can land and perch, but rarely walk. All odonates have aquatic larvae called naiads or nymphs, and all of them, larvae and adults, are carnivorous and are almost entirely insectivorous, although at the larval stage they will eat anything that they can overpower, including small fish, tadpoles, and even adult newts. The adults are superb aerial hunters and their legs are specialised for catching prey in flight. Odonata in its narrow sense forms a subgroup of the broader Odonatoptera, which contains other dragonfly-like insects ...
