Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Microlophus
''Microlophus'' is a genus of tropidurid lizards native to South America. Around 20 species are recognized and 10 of these are endemic to the Galápagos Islands, where they are commonly known as lava lizardsBenavides E, Baum R, Snell HM, Snell HL, Sites JW Jr (2009)"Island Biogeography of Galápagos Lava Lizards (Tropiduridae: ''Microlophus''): Species Diversity and Colonization of the Archipelago". (.pdf) ''Evolution'' 63 (6): 1606–1626. (they are sometimes placed in ''Tropidurus'' instead). The remaining, which often are called Pacific iguanas, are found in the Andes and along the Pacific coasts of Chile, Peru, and Ecuador. The distribution of the lava lizards and their variations in shape, colour, and behaviour show the phenomenon of adaptive radiation so typical of the inhabitants of this archipelago. One species occurs on all the central and western islands, which were perhaps connected during periods of lower sea levels, while one species each occurs on six other more pe ...

Galápagos Flycatcher
The Galápagos flycatcher (''Myiarchus magnirostris'') also known as the large-billed flycatcher is a species of bird in the family Tyrannidae. It is endemic to the Galápagos Islands, where it is present on all the main islands. Its local name is 'Papamoscas'. The species was once placed in its own genus, ''Eribates'', based upon a supposed "very long tarsus". The Galápagos flycatcher is in length and weighs 12 - 18.5 grams. It is the smallest member of its genus. Its natural habitats are tropical dry forests and tropical arid shrubland Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It ... with cacti. The Galápagos flycatcher has become used to human visitors to the Galápagos Islands and flies towards large camera lenses, perceiving its own reflected image as another bird. It h ...

Galápagos Dove
The Galápagos dove (''Zenaida galapagoensis'') is a species of bird in the family Columbidae. It is endemic to the Galápagos, off Ecuador. It is fairly common and is found in a wide range of open and semi-open habitats, especially in the arid lowlands of the archipelago. Taxonomy and systematics Two subspecies exist: * ''Zenaida galapagoensis galapagoensis'' ( Gould, 1839) – the nominate subspecies. Found on the major islands of the Galapagos, with the exception of Darwin Island and Wolf Island. * ''Zenaida galapagoensis exsul'' (Swarth, 1931) – Slightly larger and darker than ''Z. g. galapagoensis.'' Found only on Darwin Island and Wolf Island.'' Despite the geographic isolation of the bird on different islands, there is significant gene flow between the different island populations, owing to frequent migration between islands. This has not entirely prevented the formation of subspecies however, as environmental factors such as wind currents, distance between islands, and ...

Flightless Cormorant
The flightless cormorant (''Nannopterum harrisi''), also known as the Galapagos cormorant, is a cormorant endemic to the Galapagos Islands, and an example of the highly unusual fauna there. It is unique in that it is the only known cormorant that has lost the ability to fly. It was placed in its own genus, '' Nannopterum'', but then was later placed with most of the other cormorants in the genus '' Phalacrocorax''. A 2014 study supported reclassifying it and two other American cormorant species back into ''Nannopterum''. The IOC followed this classification in 2021. Description The flightless cormorant is the largest extant member of its family, in length and weighing , and its wings are about one-third the size that would be required for a bird of its proportions to fly. The keel on the breastbone, where birds attach the large muscles needed for flight, is also significantly reduced. Like all cormorants, this bird has webbed feet and sturdy legs that propel it through the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darwin's Finches
Darwin's finches (also known as the Galápagos finches) are a group of about 18 species of passerine birds. They are well known for their remarkable diversity in beak form and function. They are often classified as the subfamily Geospizinae or tribe (biology), tribe Geospizini. They belong to the Thraupidae, tanager Family (biology), family and are not closely related to the true finches. The closest known relative of the Galápagos finches is the South American ''Dull-coloured grassquit, Tiaris obscurus''. They were first collected when Second voyage of HMS Beagle, the second voyage of the ''Beagle'' visited the Galápagos Islands, with Charles Darwin on board as a gentleman naturalist. Apart from the Cocos finch, which is from Cocos Island, the others are found only on the Galápagos Islands. The term "Darwin's finches" was first applied by Percy Lowe in 1936, and popularised in 1947 by David Lack in his book ''Darwin's Finches''. Lack based his analysis on the large collectio ...

Cattle Egret
The cattle egret (''Bubulcus ibis'') is a cosmopolitan species of heron (family Ardeidae) found in the tropics, subtropics, and warm-temperate zones. It is the only member of the monotypic genus ''Bubulcus'', although some authorities regard its two subspecies as full species, the western cattle egret and the eastern cattle egret. Despite the similarities in plumage to the egrets of the genus ''Egretta'', it is more closely related to the herons of '' Ardea''. Originally native to parts of Asia, Africa, and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century. It is a white bird adorned with buff plumes in the breeding season. It nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Cattle egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inundat ...

Brown Pelican
The brown pelican (''Pelecanus occidentalis'') is a bird of the pelican family, Pelecanidae, one of three species found in the Americas and one of two that feed by diving into water. It is found on the Atlantic Coast from New Jersey to the mouth of the Amazon River, and along the Pacific Coast from British Columbia to northern Chile, including the Galapagos Islands. The nominate subspecies in its breeding plumage has a white head with a yellowish wash on the crown. The nape and neck are dark maroon–brown. The upper sides of the neck have white lines along the base of the gular pouch, and the lower fore neck has a pale yellowish patch. The male and female are similar, but the female is slightly smaller. The nonbreeding adult has a white head and neck. The pink skin around the eyes becomes dull and gray in the nonbreeding season. It lacks any red hue, and the pouch is strongly olivaceous ochre-tinged and the legs are olivaceous gray to blackish-gray. The brown pelican ...

Brown Noddy
The brown noddy or common noddy (''Anous stolidus'') is a seabird in the family Laridae. The largest of the noddies, it can be told from the closely related black noddy by its larger size and plumage, which is dark brown rather than black. The brown noddy is a tropical seabird with a worldwide distribution, ranging from Hawaii to the Tuamotu Archipelago and Australia in the Pacific Ocean, from the Red Sea to the Seychelles and Australia in the Indian Ocean and in the Caribbean to Tristan da Cunha in the Atlantic Ocean. The brown noddy is colonial, usually nesting on elevated situations on cliffs or in short trees or shrubs. It only occasionally nests on the ground. A single egg is laid by the female of a pair each breeding season. In India, the brown noddy is protected in the PM Sayeed Marine Birds Conservation Reserve. Taxonomy The first formal description of the brown noddy was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae ...

Blue-footed Booby
The blue-footed booby (''Sula nebouxii'') is a marine bird native to subtropical and tropical regions of the eastern Pacific Ocean. It is one of six species of the genus ''Sula'' – known as boobies. It is easily recognizable by its distinctive bright blue feet, which is a sexually selected trait and a product of their diet. Males display their feet in an elaborate mating ritual by lifting them up and down while strutting before the female. The female is slightly larger than the male and can measure up to long with a wingspan up to . The natural breeding habitats of the blue-footed booby are the tropical and subtropical islands of the Pacific Ocean. It can be found from the Gulf of California south along the western coasts of Central and South America to Peru. About half of all breeding pairs nest on the Galápagos Islands. Its diet mainly consists of fish, which it obtains by diving and sometimes swimming under water in search of its prey. It sometimes hunts alone, but ...

American Yellow Warbler
The yellow warbler (''Setophaga petechia'') is a New World warbler species. Yellow warblers are the most widespread species in the diverse genus '' Setophaga'', breeding in almost the whole of North America, the Caribbean, and down to northern South America. Etymology The genus name ''Setophaga'' is from Ancient Greek ''ses'', "moth", and ', "eating", and the specific ''petechia'' is from Italian ''petecchia'', a small red spot on the skin. The American yellow warbler is sometimes colloquially called the "summer yellowbird". Description and taxonomy Other than in male breeding plumage and body size, all warbler subspecies are very similar. Winter, female and immature birds all have similarly greenish-yellow uppersides and are a duller yellow below. Young males soon acquire breast and, where appropriate, head coloration. Females are somewhat duller, most notably on the head. In all, the remiges and rectrices are blackish olive with yellow edges, sometimes appearing as an in ...
