Harrisoniella Hopkinsi
''Harrisoniella hopkinsi'' is a species of phtilopterid louse that lives on and eats the feathers of albatrosses. The species was first described by W. Eichler in 1952. This species is dark brown with an elongated head, and extremely large – ''H. hopkinsi'' is one of the largest feather lice, with males reaching up to long. They live mostly on the wing feathers, but are quite able to move if disturbed or if their host bird should die. There are usually fewer than half a dozen adult specimens found on a single host bird; low compared with other species of feather lice, which may number in the hundreds. ''Harrisoniella hopkinsi'' has been found on the feathers of the wandering albatross (''Diomedea exulans'') and the southern royal albatross The southern royal albatross or toroa, (''Diomedea epomophora'') is a large seabird from the albatross family. At an average wingspan of above , it is one of the two largest species of albatross, together with the wandering albatross. R ...

Philopteridae
The Philopteridae are a family of Ischnocera, chewing lice mostly parasitic on birds. The taxonomy and systematics of the group are in need of revision; the Philopteridae are almost certainly paraphyletic. Genera Some notable species are also listed. * '' Acidoproctus'' * '' Acutifrons'' * '' Aegypoecus'' * '' Alcedoecus'' * '' Alcedoffula'' * '' Anaticola'' * '' Anatoecus'' * '' Aquanirmus'' * '' Ardeicola'' * '' Ardeiphagus'' * '' Auricotes'' * '' Austrogoniodes'' * '' Austrophilopterus'' * '' Bedfordiella'' * '' Bizarrifrons'' * '' Bobdalglieshia'' * '' Bothriometopus'' * ''Brueelia'' * '' Bucerocophorus'' * '' Buceroemersonia'' * '' Buceronirmus'' * '' Bucorvellus'' * '' Buerelius'' * ''Campanulotes'' * '' Capraiella'' * '' Caracaricola'' * '' Carduiceps'' * '' Centropodiella'' * '' Chelopistes'' * '' Cirrophthirius'' * '' Colilipeurus'' * '' Colinicola'' * '' Coloceras'' * ''Columbicola'' ** ''Columbicola extinctus ''Columbicola extinctus'', also known as the passenger p ...

Louse
Louse ( : lice) is the common name for any member of the clade Phthiraptera, which contains nearly 5,000 species of wingless parasitic insects. Phthiraptera has variously been recognized as an order, infraorder, or a parvorder, as a result of developments in phylogenetic research. Lice are obligate parasites, living externally on warm-blooded hosts which include every species of bird and mammal, except for monotremes, pangolins, and bats. Lice are vectors of diseases such as typhus. Chewing lice live among the hairs or feathers of their host and feed on skin and debris, while sucking lice pierce the host's skin and feed on blood and other secretions. They usually spend their whole life on a single host, cementing their eggs, called nits, to hairs or feathers. The eggs hatch into nymphs, which moult three times before becoming fully grown, a process that takes about four weeks. Genetic evidence indicates that lice are a highly modified lineage of Psocoptera (now called Ps ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albatross
Albatrosses, of the biological family Diomedeidae, are large seabirds related to the procellariids, storm petrels, and diving petrels in the order Procellariiformes (the tubenoses). They range widely in the Southern Ocean and the North Pacific. They are absent from the North Atlantic, although fossil remains show they once occurred there and occasional vagrants are found. Albatrosses are among the largest of flying birds, and species of the genus ''Diomedea'' (great albatrosses) have the longest wingspans of any extant birds, reaching up to . The albatrosses are usually regarded as falling into four genera, but disagreement exists over the number of species. Albatrosses are highly efficient in the air, using dynamic soaring and slope soaring to cover great distances with little exertion. They feed on squid, fish, and krill by either scavenging, surface seizing, or diving. Albatrosses are colonial, nesting for the most part on remote oceanic islands, often with several spe ...

Wandering Albatross
The wandering albatross, snowy albatross, white-winged albatross or goonie (''Diomedea exulans'') is a large seabird from the family Diomedeidae, which has a circumpolar range in the Southern Ocean. It was the last species of albatross to be described, and was long considered the same species as the Tristan albatross and the Antipodean albatross. A few authors still consider them all subspecies of the same species. The SACC has a proposal on the table to split this species, and BirdLife International has already split it. Together with the Amsterdam albatross, it forms the wandering albatross species complex. The wandering albatross is one of the two largest members of the genus ''Diomedea'' (the great albatrosses), being similar in size to the southern royal albatross. It is one of the largest, best known, and most studied species of bird in the world. It has the greatest known wingspan of any living bird, and is also one of the most far-ranging birds. Some individual wandering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Royal Albatross
The southern royal albatross or toroa, (''Diomedea epomophora'') is a large seabird from the albatross family. At an average wingspan of above , it is one of the two largest species of albatross, together with the wandering albatross. Recent studies indicate that the southern royal albatross may, on average, be somewhat larger than the wandering albatross in mass and have a similar wingspan, although other sources indicate roughly similar size for the two species and the wandering species may have a larger average (and maximum) wingspan in some colonies.''CRC Handbook of Avian Body Masses, 2nd Edition'' by John B. Dunning Jr. (Editor). CRC Press (2008), . Taxonomy Albatrosses belong to family Diomedeidae of the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns; the nostrils of the albatross are on the sides of the bill ...

Parasites Of Birds
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; an ect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
