White-throated Swift
The white-throated swift (''Aeronautes saxatalis'') is a Swift (bird), swift of the family Apodidae native to western North America, south to cordilleran western Honduras.Ryan TP, Collins CT. 2000. White-throated Swift (''Aeronautes saxatalis''). Version 2.0. In: Poole AF, Gill FB, editors. The Birds of North America [Internet]. [cited 2018 Oct 3]; Ithaca (NY): Cornell Lab of Ornithology. . Its coastal range extends as far north as Northern California, while inland it has migratory populations found throughout the Great Basin and Rocky Mountain regions, ranging as far north as southern British Columbia. White-throated swifts are found in open areas near cliffs, rock faces, or man-made structures, where they roost. Swifts are social birds, and groups are often seen roosting and foraging for flying insects together. Description The white-throated swift is medium-sized bird that is primarily black and white. Its back and wings are blackish-brown or black, and its breast, belly, chi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spokane County, Washington
Spokane County is a county located in the U.S. state of Washington. As of the 2020 census, its population was 539,339, making it the fourth-most populous county in Washington. The largest city and county seat is Spokane, the second largest city in the state after Seattle. The county is named after the Spokane tribe. Spokane County is part of the Spokane-Spokane Valley metropolitan statistical area, which is also part of the greater Spokane-Coeur d'Alene combined statistical area that includes nearby Kootenai County, Idaho. History The first humans to arrive in what is now Spokane County arrived between 12,000 and 8,000 years ago and were hunter-gatherer societies who lived off the plentiful game in the area. Initially, the settlers hunted predominantly bison and antelope, but after the game migrated out of the region, the native people became dependent on gathering various roots, berries, and nuts, and harvesting fish.Ruby et al. (2006) pp. 5–6 The Spokane tribe, after w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Texas Panhandle
The Texas Panhandle is a region of the U.S. state of Texas consisting of the northernmost 26 counties in the state. The panhandle is a square-shaped area bordered by New Mexico to the west and Oklahoma to the north and east. It is adjacent to the Oklahoma Panhandle. ''The Handbook of Texas'' defines the southern border of Swisher County as the southern boundary of the Texas Panhandle region. Its land area is , or nearly 10% of the state's total. The Texas Panhandle is slightly larger in size than the US state of West Virginia. An additional is covered by water. Its population as of the 2010 census was 427,927 residents, or 1.7% of the state's total population. As of the 2010 census, the population density for the region was . However, more than 72% of the Panhandle's residents live in the Amarillo Metropolitan Area, which is the largest and fastest-growing urban area in the region.

American Kestrel
The American kestrel (''Falco sparverius''), also called the sparrow hawk, is the smallest and most common falcon in North America. It has a roughly two-to-one range in size over subspecies and sex, varying in size from about the weight of a blue jay to a mourning dove. It also ranges to South America and is a well-established species that has evolved into 17 subspecies adapted to different environments and habitats throughout the Americas. It exhibits sexual dimorphism in size (females being moderately larger) and plumage, although both sexes have a rufous back with noticeable barring. Its plumage is colorful and attractive, and juveniles are similar in plumage to adults. The American kestrel usually hunts in energy-conserving fashion by perching and scanning the ground for prey to ambush, though it also hunts from the air. It sometimes hovers in the air with rapid wing beats while homing in on prey. Its diet typically consists of grasshoppers and other insects, lizards, m ...

Prairie Falcon
The prairie falcon (''Falco mexicanus'') is a medium-large sized falcon of western North America. It is about the size of a peregrine falcon or a crow, with an average length of 40 cm (16 in), wingspan of approximately 1 meter (40 in), and average weight of 720 g (1.6 lb). As in all falcons, females are noticeably bigger than males. Though a separate species from the peregrine, the prairie falcon is basically an arid environment adaptation of the early peregrine falcon lineage, able to subsist on less food than the peregrine, and generally lighter in weight than a peregrine of similar wing span. Having evolved in a harsh desert environment with low prey density, the prairie falcon has developed into an aggressive and opportunistic hunter of a wide range of both mammal and bird prey. It will regularly take prey from the size of sparrows to approximately its own weight, and occasionally much larger. It is the only larger falcon native only to North America. ...

Peregrine Falcon
The peregrine falcon (''Falco peregrinus''), also known as the peregrine, and historically as the duck hawk in North America, is a Cosmopolitan distribution, cosmopolitan bird of prey (Bird of prey, raptor) in the family (biology), family Falconidae. A large, Corvus (genus), crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed, reaching over during its characteristic hunting stoop (high-speed dive), making it the fastest bird in the world, as well as the Fastest animals, fastest member of the animal kingdom. According to a ''National Geographic (U.S. TV channel), National Geographic'' TV program, the highest measured speed of a peregrine falcon is . As is typical for avivore, bird-eating raptors, peregrine falcons are Sexual dimorphism, sexually dimorphic, with females being considerably larger than males. The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buccal Space
The buccal space (also termed the buccinator space) is a fascial space of the head and neck (sometimes also termed fascial tissue spaces or tissue spaces). It is a potential space in the cheek, and is paired on each side. The buccal space is superficial to the buccinator muscle and deep to the platysma muscle and the skin. The buccal space is part of the subcutaneous space, which is continuous from head to toe. Structure Boundaries The boundaries of each buccal space are: * the angle of the mouth anteriorly, * the masseter muscle posteriorly, * the zygomatic process of the maxilla and the zygomaticus muscles superiorly, * the depressor anguli oris muscle and the attachment of the deep fascia to the mandible inferiorly, * the buccinator muscle medially (the buccal space is superficial to the buccinator), * the platysma muscle, subcutaneous tissue and skin laterally (the space is deep to platysma). Communications * to the pterygomandibular space, infratemporal space, submassete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemiptera
Hemiptera (; ) is an order (biology), order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, Reduviidae, assassin bugs, Cimex, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking Insect mouthparts, mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.''

Violet-green Swallow
The violet-green swallow (''Tachycineta thalassina'') is a small North American passerine bird in the Hirundinidae, swallow family. These aerial insectivores are distributed along the west coast from Alaska to Mexico, extending as far east as Montana and Texas. With an appearance very similar to the tree swallow, these individuals can be identified by the white Rump (animal), rump side-patches that appear to separate their green back and purple tail. Violet-green swallows are secondary cavity nesters, found in a number of habitats including deciduous and Pinophyta, coniferous forest. In addition to nesting in Tree hollow, tree holes within these habitats, they are also widely observed nesting in the cracks of large cliffs. Description The distinct body form of swallows distinguishes them from other passerine birds. Their long pointed wings and slim, streamlined body evolved to catch insects while in flight. The body of the violet-green swallow is no exception. With an average bod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Draft
In meteorology, an updraft is a small-scale current of rising air, often within a cloud. Overview Localized regions of warm or cool air will exhibit vertical movement. A mass of warm air will typically be less dense than the surrounding region, and so will rise until it reaches air that is either warmer or less dense than itself. The converse will occur for a mass of cool air, and is known as subsidence. This movement of large volumes of air, especially when regions of hot, wet air rise, can create large clouds, and is the central source of thunderstorms. Drafts can also be conceived by low or high pressure regions. A low pressure region will attract air from the surrounding area, which will move towards the center and then rise, creating an updraft. A high pressure region will attract air from the surrounding area, which will move towards the center and sink, spawning a downdraft. Updrafts and downdrafts, along with wind shear in general, are a major contributor to airplane cras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Rough-winged Swallow
The northern rough-winged swallow (''Stelgidopteryx serripennis'') is a small, migratory swallow. It is very similar to the southern rough-winged swallow, ''Stelgidopteryx ruficollis''. Taxonomy and etymology The genus name, ''Stelgidopteryx'', is from Ancient Greek and means "scraper wing" and the species name, ''serripennis'', is derived from Latin and means "saw feather". In the common name, "rough-winged" refers to the serrated edge feathers on the wing of this bird; this feature would only be apparent when holding this bird. Subspecies Six subspecies of the northern rough-winged swallow are currently recognized. *''S. s. serripennis'' is the nominate subspecies and can be found to occur in southern Alaska and Canada to the southern United States. They are found to usually winter in southern Florida and from southwestern Mexico to Panama. It was described by Audubon in 1838. *''S. s. psammochroa'' was described by Ludlow Griscom in 1929. It breeds in the southwestern US a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
