Brown-headed Nuthatch
The brown-headed nuthatch (''Sitta pusilla'') is a small songbird endemic to pine Temperate coniferous forest, forests throughout the Southeastern United States. Genetic analyses indicated low differentiation between northern and southern populations in Florida, but the study also found lower genetic diversity among south Florida populations that may be a result of the increased habitat fragmentation that was documented. The Bahama nuthatch was formerly considered a subspecies (''S. p. insularis''), has since been reclassified as its own separate species. Two recent studies assessing vocalizations in Bahama and continental nuthatch populations found important differences. One of the studies also demonstrated that continental and Bahama populations did not respond aggressively to calls of the other population. This type of call-response study is often used to help define cryptic species. The bird, like other nuthatches, possesses a sharp black nail (engineering), nail- ...

Endemic Birds Of The Eastern United States
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Nuthatches
The nuthatches () constitute a genus, ''Sitta'', of small passerine birds belonging to the family Sittidae. Characterised by large heads, short tails, and powerful bills and feet, nuthatches advertise their territory using loud, simple songs. Most species exhibit grey or bluish upper parts and a black eye stripe. Most nuthatches breed in the temperate or montane forest, montane woodlands of the Northern Hemisphere, although two species have adapted to rocky habitats in the warmer and drier regions of Eurasia. However, the greatest diversity is in South Asia, Southern Asia, and similarities between the species have made it difficult to identify distinct species. All members of this genus nest in holes or crevices. Most species are bird migration, non-migratory and live in their habitat year-round, although the North American red-breasted nuthatch migrates to warmer regions during the winter. A few nuthatch species have restricted ranges and face threats from deforestation. Nuthat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-breasted Nuthatch
The white-breasted nuthatch (''Sitta carolinensis'') is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring approximately in length. Coloration varies somewhat along the species' range, but the are light blue-gray, with a black and nape in males, while females have a dark gray crown. The are whitish, with a reddish tinge on the lower abdomen. Despite not being closely related, the white-breasted nuthatch and the white wagtail are very similar in plumage. The white-breasted nuthatch is a noisy bird. It has a nasal voice and often utters little cries or vocalizations, often composed of repetitions of small invariant whistles. In summer, it is an exclusively insectivorous bird, consuming a wide range of arthropods, but in winter its diet consists mainly of seeds. The nest is located in the cavity of a tree. The clutch consists of five to nine eggs, incubated for two weeks by the female, who is fed by the male. The two adults then feed ...

Red-breasted Nuthatch
The red-breasted nuthatch (''Sitta canadensis'') is a small songbird. The adult has blue-grey upperparts with cinnamon underparts, a white throat and face with a black stripe through the eyes, a straight grey bill and a black crown. Its call, which has been likened to a tin trumpet, is high-pitched and nasal. It breeds in coniferous forests across Canada, Alaska and the northeastern and western United States. Though often a permanent resident, it regularly irrupts further south if its food supply fails. There are records of vagrants occurring as far south as the Gulf Coast and northern Mexico. It forages on the trunks and large branches of trees, often descending head first, sometimes catching insects in flight. It eats mainly insects and seeds, especially from conifers. It excavates its nest in dead wood, often close to the ground, smearing the entrance with pitch. Taxonomy In 1760, the French zoologist Mathurin Jacques Brisson included a description of the red-breasted n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber Duck
A rubber duck, or a rubber duckie, is a toy shaped like a duck, that is usually yellow with a flat base. It may be made of rubber or rubber-like material such as vinyl plastic. Rubber ducks were invented in the late 19th century when it became possible to more easily shape rubber, and are believed to improve developmental skills in children during water play. The yellow rubber duck has achieved an iconic status in Western World, Western popular culture, pop culture and is often symbolically linked to bathing. Various novelty variations of the toy are produced, and many organisations use yellow rubber ducks in rubber duck races for fundraising worldwide. History The history of the rubber duck is linked to the emergence of rubber manufacturing in the late 19th century. The earliest rubber ducks were made from harder rubber when manufacturers began using Charles Goodyear's invention, Vulcanization, vulcanized rubber. Consequently, these solid rubber ducks were not capable of fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pygmy Nuthatch
The pygmy nuthatch (''Sitta pygmaea'') is a tiny songbird, about long and about 10 grams in weight. Description Measurements: * Length: * Weight: * Wingspan: It ranges from southern British Columbia south through various discontinuous parts of the western U.S. ( northwest U.S., Sierra Nevada range, southern Rockies, etc.), to central Mexico. It is usually found in pines (especially ponderosa pines), Douglas-firs, and other conifers. Pygmy nuthatches clamber acrobatically in the foliage of these trees, feeding on insects and seeds; less often they creep along limbs or the trunk like bigger nuthatches. Pygmy nuthatches nest in cavities in dead stubs of conifers, lining the bottom of the cavity with pine-cone scales, plant down, and other soft plant and animal materials. They may fill cracks or crevices around the entrance with fur; the function of this behavior is unknown. The female lays 4–9 eggs, which are white with fine reddish-brown spotting. She does most ...

Tool Use By Non-humans
Tool use by non-humans is a phenomenon in which a non-human animal uses any kind of tool in order to achieve a goal such as acquiring food and water, grooming, combat, defence, communication, recreation or construction. Originally thought to be a skill possessed only by humans, some tool use requires a sophisticated level of cognition. There is considerable discussion about the definition of what constitutes a tool and therefore which behaviours can be considered true examples of tool use. A wide range of animals, including mammals, birds, fish, cephalopods, and insects, are considered to use tools. Primates are well known for using tools for hunting or gathering food and water, cover for rain, and self-defence. Chimpanzees have often been the object of study in regard to their usage of tools, most famously by Jane Goodall, since these animals are frequently kept in captivity and are closely related to humans. Wild tool use in other primates, especially among apes and monkeys, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suet
Suet ( ) is the raw, hard fat of beef, lamb or mutton found around the loins and kidneys. Suet has a melting point of between and solidification (or congelation) between . Its high smoke point makes it ideal for deep frying and pastry production. The primary use of suet is in tallow, although it is also used as an ingredient in cooking, especially in traditional baked puddings, such as British Christmas pudding. Suet is rendered into tallow by melting and extended simmering, followed by straining, then cooling. The process may be repeated to refine the product. Etymology The word ''suet'' is derived from Anglo-Norman , from Old French , from Latin (' tallow', 'grease', 'hard animal fat'). ''Sebum'' is from the Proto-Indo-European root ('pour out, trickle'), so it shares a root with ''sap'' and ''soap''. Use In cuisine As suet is the fat from around the kidneys, the connective tissue, blood and other non-fat content must be removed. It must be refrigerated ...
