Plasmodium Vaughani
''Plasmodium vaughani'' is a parasite of the genus ''Plasmodium'', and the type species of the subgenus ''Novyella''. As in all ''Plasmodium'' species, ''P. vaughani'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are birds. Taxonomy The parasite was first described by Novy & MacNeal in 1904. Subspecies *''Plasmodium vaughani merulae'' Corradetti and Scanga 1972 *''Plasmodium vaughani tenue'' Laveran and Marullaz 1914 *''Plasmodium vaughani vaughani'' Novy and MacNeal 1904 Description The length of the asexual cycle is 24 hours. Trophozoites: Ring forms are unusual. The trophozoite is usually irregular in outline. The nucleus is small and there may be a single clear outgrowth of the cytoplasm. One or two small pigment granules may be seen. These forms are found in mature and polychromatic erythrocytes. Schizonts: These are usually found in a polar or sub polar position within the host cell but may be found anywhere within the cell. They are ...

Plasmodium
''Plasmodium'' is a genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects. The life cycles of ''Plasmodium'' species involve development in a blood-feeding insect host which then injects parasites into a vertebrate host during a blood meal. Parasites grow within a vertebrate body tissue (often the liver) before entering the bloodstream to infect red blood cells. The ensuing destruction of host red blood cells can result in malaria. During this infection, some parasites are picked up by a blood-feeding insect (mosquitoes in majority cases), continuing the life cycle. ''Plasmodium'' is a member of the phylum Apicomplexa, a large group of parasitic eukaryotes. Within Apicomplexa, ''Plasmodium'' is in the order Haemosporida and family Plasmodiidae. Over 200 species of ''Plasmodium'' have been described, many of which have been subdivided into 14 subgenera based on parasite morphology and host range. Evolutionary relationships among different ''Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culex Pipiens
''Culex pipiens'', commonly referred to as the common house mosquito, is a species of mosquito. House mosquitoes are some of the most common mosquitoes in the United States. More specifically, ''Culex pipiens'' is considered as the northern house mosquito, as it is the most common mosquito to the northern regions of the US. North of the 39th parallel north in the US, only ''C. pipiens'' are present, whereas south of the 36th parallel north, only ''C. quinquefasciatus'' (commonly known as the southern house mosquito) are present. Additionally, they can be found in both urban and suburban temperate and tropical regions across the world. ''Culex pipiens'' diet typically consists of vertebrate blood, as they consume human blood, but prefer bird blood of species that are nearly linked to human interaction, such as doves and pigeons. Furthermore, at the end of the summer and the start of the fall season before it is time for them to overwinter, ''C. pipiens'' subsist on nectar and ot ...

Quiscalus Quiscula
The common grackle (''Quiscalus quiscula'') is a species of large icterid bird found in large numbers through much of North America. First described in 1758 by Carl Linnaeus, the common grackle has three subspecies. Adult common grackles have a long and dark bill, pale yellow eyes, and a long tail. Adults often have an iridescent appearance on their head, especially males. Common grackles can be found widely across North America east of the Rocky Mountains. Taxonomy The common grackle was first described in 1758 by Carl Linnaeus in the 10th edition of Systema Naturae, tenth edition of ''Systema Naturae'', as ''Gracula quiscula''. It was assigned to the genus ''Quiscalus'' by French people, French ornithologist Louis Jean Pierre Vieillot in his 1816 ''Dictionnaire d'histoire naturelle''. Three subspecies are recognized: *the Florida grackle (''Q. q. quiscula'') (Linnaeus 1758), the nominate subspecies *the purple grackle (''Q. q. stonei'') (Chapman, 1935) *the bronzed grackle (' ...

Ploceus Cucullatus
The village weaver (''Ploceus cucullatus''), also known as the spotted-backed weaver or black-headed weaver (the latter leading to easy confusion with '' P. melanocephalus''), is a species of bird in the family Ploceidae found in much of sub-Saharan Africa. It has also been introduced to Portugal and Venezuela as well as to the islands of Hispaniola, Martinique, Puerto Rico, Mauritius and Réunion. This often abundant species occurs in a wide range of open or semi-open habitats, including woodlands and human habitation, and frequently forms large noisy colonies in towns, villages and hotel grounds. This weaver builds a large coarsely woven nest made of grass and leaf strips with a downward facing entrance which is suspended from a branch in a tree. Two to three eggs are laid. Village weavers are colonial breeders, so many nests may hang from one tree. Village weavers feed principally on seeds and grain, and can be a crop pest, but it will readily take insects, especially wh ...

Passer Domesticus
The house sparrow (''Passer domesticus'') is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of and a mass of . Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus ''Passer'', the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird. The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, and deserts away from human development. It feeds mostly on the seeds of grains and weeds, but it is an opportunistic eater and commonly eats insects and many othe ...

Loxigilla Violacea
The Greater Antillean bullfinch (''Melopyrrha violacea'') is a species of bird in the family Thraupidae. Distribution and habitat It is found in the Bahamas, Hispaniola (the Dominican Republic and Haiti, as well as surrounding islands), Jamaica, and the Turks and Caicos Islands. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, subtropical or tropical dry shrubland, and heavily degraded former forest. Taxonomy The Greater Antillean bullfinch was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Loxia violacea''. The specific epithet ''violacea'' is from Latin ''violaceus'' meaning "violet-coloured".

Leiothrix Lutea
The red-billed leiothrix (''Leiothrix lutea'') is a member of the family Leiothrichidae, native to southern China and the Himalayas. Adults have bright red bills and a dull yellow ring around their eyes. Their backs are dull olive green, and they have a bright yellow-orange throat with a yellow chin; females are somewhat duller than males, and juveniles have black bills. It has also been introduced in various parts of the world, with small populations of escapees having existed in Japan since the 1980s. It has become a common cagebird and amongst aviculturists it goes by various names: Pekin robin, Pekin nightingale, Japanese nightingale, and Japanese (hill) robin, the last two being misnomers as it is not native to Japan (although it has been introduced and naturalised there).Long, John L.

Junco Hyemalis
The dark-eyed junco (''Junco hyemalis'') is a species of junco, a group of small, grayish New World sparrows. This bird is common across much of temperate North America and in summer ranges far into the Arctic. It is a very variable species, much like the related fox sparrow (''Passerella iliaca''), and its systematics are still not completely untangled. Taxonomy The dark-eyed junco was species description, formally described by the Swedish naturalist Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae, 10th edition of ''Systema Naturae'' as ''Fringilla hyemalis''. The description consisted merely of the laconic remark "''F[ringilla] nigra, ventre albo.'' ("A black 'finch' with white belly") and a statement that it came from America. Linnaeus based his description on the "Snow-Bird" that Mark Catesby had described and illustrated in his ''The Natural History of Carolina, Florida and the Bahama Islands''. The Bill of this Bird is white: The Breast and Belly white. All ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erithacus Rubecula
The European robin (''Erithacus rubecula''), known simply as the robin or robin redbreast in Great Britain & Ireland, is a small insectivorous passerine bird that belongs to the chat subfamily of the Old World flycatcher family. About in length, the male and female are similar in colouration, with an orange breast and face lined with grey, brown upper-parts and a whitish belly. It is found across Europe, east to Western Siberia and south to North Africa; it is sedentary in most of its range except the far north. The term ''robin'' is also applied to some birds in other families with red or orange breasts. These include the American robin (''Turdus migratorius''), a thrush, and the Australasian robins of the family Petroicidae, the relationships of which are unclear. Taxonomy, etymology and systematics The European robin was described by Carl Linnaeus in 1758 in the 10th edition of his ''Systema Naturae'' under the binomial name ''Motacilla rubecula''.

Setophaga Petechia
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 indis ...
