American Three-toed Woodpecker
The American three-toed woodpecker (''Picoides dorsalis'') is a medium-sized woodpecker (family Picidae), which is native to North America. Description This woodpecker has a length of , a wingspan of , and an average weight of ; its maximum lifespan in the wild is 6 years. It closely resembles the black-backed woodpecker, which is also three-toed. Until recently, it was considered to be the same species as the Eurasian three-toed woodpecker, ''P. tridactylus''. Adults are black on the head, wings and rump, and white from the throat to the belly; the flanks are white with black bars. The back is white with black bars and the tail is black with the white outer feathers barred with black. The adult male has a yellow cap. Breeding The breeding habitat is coniferous forests across western Canada, Alaska and the western and extreme northeastern United States. It has also been breeding in various spots in Michigan's upper peninsula, and has been recorded breeding in Minnesota five ti ...

Birds Described In 1858
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of Canada
This is a list of bird species confirmed in Canada. Unless otherwise noted, the list is that of ''Bird Checklists of the World'' as of July 2022. Of the 703 species listed here, 235 are accidental. Twelve species were introduced to North America or directly to Canada, three species are extinct, and three (possibly four) have been extirpated. One species of uncertain origin is also included. This list is presented in the taxonomic sequence of the ''Check-list of North and Middle American Birds'', 7th edition through the 63rd Supplement, published by the American Ornithological Society (AOS). Common and scientific names are also those of the ''Check-list'', except that the common names of families are from the Clements taxonomy because the AOS list does not include them. Canadian birds most closely resemble those of Eurasia, which was connected to the continent as part of the supercontinent Laurasia until around 60 million years ago. Many families which occur in Canada are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Picoides
''Picoides'' is a genus of woodpeckers (family Picidae) that are native to Eurasia and North America, commonly known as three-toed woodpeckers. Taxonomy The genus ''Picoides'' was introduced by the French naturalist Bernard Germain de Lacépède in 1799. The type species was subsequently designated as the Eurasian three-toed woodpecker (''Picoides tridactylus'') by the English zoologist George Robert Gray in 1840. The genus name combines the Latin ''Picus'' for a woodpecker and the Greek ''-oidēs'' meaning "resembling". The genus ''Picoides'' formerly contained around 12 species. In 2015 a molecular phylogenetic analysis of nuclear and mitochondrial DNA sequences from pied woodpeckers found that three existing genera (''Picoides'', ''Veniliornis'' and '' Dendropicos'') were polyphyletic. After the resurrection of five monophyletic genera and the subsequent rearrangement in which most of the former members of ''Picoides'' were moved to ''Leuconotopicus'' and ''Dryobates'', only ...

Cornell Lab Of Ornithology
The Cornell Lab of Ornithology is a member-supported unit of Cornell University in Ithaca, New York, which studies birds and other wildlife. It is housed in the Imogene Powers Johnson Center for Birds and Biodiversity in Sapsucker Woods Sanctuary. Approximately 250 scientists, professors, staff, and students work in a variety of programs devoted to the Lab's mission: interpreting and conserving the Earth's biological diversity through research, education, and citizen science focused on birds. Work at the Lab is supported primarily by its 75,000 members. The Cornell Lab publishes books under the Cornell Lab Publishing Group, a quarterly publication, ''Living Bird'' magazine, and a monthly electronic newsletter. It manages numerous citizen science projects and websites, including the Webby Award-winning ''All About Birds''. History The Cornell Lab of Ornithology was founded by Arthur A. Allen who lobbied for creation of the country's first graduate program in ornithology, estab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
