Juniper Titmouse
The juniper titmouse (''Baeolophus ridgwayi'') is a passerine bird in the tit family Paridae. The American Ornithologists' Union split the plain titmouse into the oak titmouse and the juniper titmouse in 1996, due to distinct differences in song, preferred habitat, and genetic makeup. The juniper titmouse is a small, gray bird with small tuft or crest. The face is plain, and the undersides are a lighter gray. Sexes are similar. This titmouse lives year-round primarily in the Great Basin, but is resident from southeastern Oregon and central Colorado south to the eastern Mojave Desert in California and central Arizona, as far as west Texas and extreme northeastern Sonora, Mexico-(the Madrean sky islands). It prefers open woodlands of warm, dry pinyon-juniper, juniper and desert riparian woods. Juniper titmice will sleep in cavities, dense foliage, or birdhouses. When roosting in foliage, the titmouse chooses a twig surrounded by dense foliage or an accumulation of dead pine nee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Wallace Richmond
Charles Wallace Richmond (December 31, 1868 – May 19, 1932) was an American ornithologist. He is best remembered for a compilation of the Latin names of birds that is called the Richmond Index. Life and work He was born in Kenosha, Wisconsin and was the eldest son of Edward Leslie and Josephine Ellen Richmond. His mother died when he was 12. His father who was a railway mail clerk moved to Washington, D.C. and joined the Government Printing House there. His father remarried and he had the additional duty of taking care of younger stepbrothers. During his early life he earned extra income for the family by leaving school and working as a page in the House of Representatives. At the age of 15 he got a position as a messenger in the Geological Survey. In 1897 he graduated after studied medicine in Georgetown University and in the next year he married Louise H. Seville. While still at Wisconsin he had collected the eggs of a Kingbird and when he moved to Washington, in 1881. He visit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baeolophus
''Baeolophus'' is a genus of birds in the family Paridae. Its members are commonly known as titmice. All the species are native to North America. In the past, most authorities retained ''Baeolophus'' as a subgenus within the genus ''Parus'', but treatment as a distinct genus, initiated by the American Ornithological Society, is now widely accepted.Del Hoyo, J.; Elliot, A. & Christie D. (editors). (2007).

David Allen Sibley
David Allen Sibley (born October 22, 1961, in Plattsburgh, New York) is an American ornithologist. He is the author and illustrator of ''The Sibley Guide to Birds'', which rivals Roger Tory Peterson's as the most comprehensive guides for North American ornithological field identification. Life and work The son of Yale University ornithologist Fred Sibley, David Sibley began birding in childhood. Sibley got his start as a birdwatcher in Cape May Point, New Jersey in 1980, after dropping out of college. A largely self-taught bird illustrator, he was inspired to pursue creating his own illustrated field guide after leading tours in the 1980s and 1990s and finding that existing field guides did not generally illustrate or describe alternate or juvenile plumages of birds. He cites European wildlife artist Lars Jonsson as a great influence on his own work. In 2002, he received the Roger Tory Peterson Award from the American Birding Association for lifetime achievement in promotin ...

Tufted Titmouse
The tufted titmouse (''Baeolophus bicolor'') is a small songbird from North America, a species in the tit and chickadee family ( Paridae). The black-crested titmouse, found from central and southern Texas southward, was included as a subspecies, but now is considered a separate species, ''Baeolophus atricristatus''. Name The genus name ''Baeolophus'' translates to ''small crested'' and is a compound of the Ancient Greek words : baiós—"small", and : "lόphοs"—crest. The species name ''bicolor'' means ''two-colored''. Description Measurements: * Length: * Weight: * Wingspan: These small birds are approximately in length, with a white front, and grey upper body outlined with rust colored flanks. Other characteristics include their black foreheads, and the tufted grey crest on their heads. In juveniles, the black forehead is greatly diminished such that they may be confused with the oak titmouse (although their ranges do not overlap). Males tend to be larger tha ...

Altricial
In biology, altricial species are those in which the young are underdeveloped at the time of birth, but with the aid of their parents mature after birth. Precocial species are those in which the young are relatively mature and mobile from the moment of birth or hatching. Precocial species are normally nidifugous, meaning that they leave the nest shortly after birth or hatching. These categories form a continuum, without distinct gaps between them. Altriciality Etymology The word is derived from the Latin root ''alere'', meaning "to nurse, to rear, or to nourish" and indicates the need for young to be fed and taken care of for a long duration. By contrast, species whose young are immediately or quickly mobile are called ''precocial''. Precociality Etymology The word "precocial" is derived from the same root as ''precocious'', implying early maturity in both cases. Superprecociality Extremely precocial species are called "superprecocial". Examples are the megapode birds, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawking (birds)
Hawking is a feeding strategy in birds involving catching flying insects in the air. The term usually refers to a technique of sallying out from a perch to snatch an insect and then returning to the same or a different perch, though it also applies to birds that spend almost their entire lives on the wing. This technique is called "flycatching" and some birds known for it are several families of "flycatchers": Old World flycatchers, monarch flycatchers, and tyrant flycatchers. Other birds, such as swifts, swallows, and nightjars, also take insects on the wing in continuous aerial feeding. The term "hawking" comes from the similarity of this behavior to the way hawks take prey in flight, although, whereas raptors may catch prey with their feet, hawking is the behavior of catching insects in the bill. Many birds have a combined strategy of both hawking insects and gleaning them from foliage. Flycatching The various methods of taking insects have been categorized as: gleani ...

Mixed-species Feeding Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role.

Desert Riparian
Desert riparian is a North American desert vegetation type (or biome) occurring in the bottoms of valleys, canyons, and other watercourses that have water at or near the surface most of the year.Pam MacKay, Mojave Desert Wildflowers, 2nd Ed., p. 20-21 The visual character is of large, lush, perennial green trees surrounded by dry desert vegetation and soil coloration. The area may be in a patch surrounding a spring such as an oasis, or in a strand following the course of water flow, such as a bosque. The soil in this biome is typically moist and ranges from rocky and sandy to silty alluvium. This biome has seasonal variation, with hot, dry summers and cool, moist winters. Precipitation mostly occurs during the winter, and ranges from 8 to 25 cm each year. It is contrasted with the desert dry wash vegetation type, in which water at or near the surface is lacking most of the year, such as arroyos. Over 80% of known desert wildlife species use desert riparian areas. Common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juniper
Junipers are coniferous trees and shrubs in the genus ''Juniperus'' () of the cypress family Cupressaceae. Depending on the taxonomy, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, throughout parts of western, central and southern Asia, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of in southeastern Tibet and the northern Himalayas, creating one of the highest tree lines on earth. Description Junipers vary in size and shape from tall trees, tall, to columnar or low-spreading shrubs with long, trailing branches. They are evergreen with needle-like and/or scale-like leaves. They can be either monoecious or dioecious. The female seed cones are very distinctive, with fleshy, fruit-like coalescing scales which fuse together to form a berrylike structure ( galbulus), long, with one to 12 u ...
