Petronia
The rock sparrow or rock petronia (''Petronia petronia'') is a small passerine bird in the sparrow family Passeridae. It is the only member of the genus ''Petronia''. It breeds on barren rocky hills from the Iberian peninsula and western north Africa across southern Europe and through the Palearctic Siberia and north and central China. It is largely resident in the west of its range, but Asian birds migrate to more southerly areas, or move down the mountains. Taxonomy The first formal description of the rock sparrow was by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his ''Systema Naturae''. He introduced the binomial name ''Fringilla petronia''. It is now the only species in the genus ''Petronia'' that was introduced by the German naturalist Johann Jakob Kaup in 1829. ''Petronia'' is a local name for the rock sparrow from the Bologna area of Italy. Seven subspecies are recognised: * ''P. p. petronia'' (Linnaeus, 1766) – Madeira and Canary Islands ...

Petronia Xanthocollis
The yellow-throated sparrow or chestnut-shouldered petronia (''Gymnoris xanthocollis'') is a species of sparrow found in southern Asia. Description It has a finer bill than typical sparrows of the genus ''Passer'' and unlike them has no streaks on the plumage. The white double wing bar on the shoulder is diagnostic on the otherwise dull grey-brown sparrow. Males have a chestnut shoulder patch which can sometimes be hard to see. They also have a pale yellow spot on the throat in fresh plumage. Females are duller and lack the chestnut shoulder patch. The yellow spot is much reduced or lacking in females. This species is tree-loving although sometimes seen on wires and on the ground, where it has a hopping gait. The usual call is a ''chirrup'' but the song is distinctive and repetitive '. It has a bounding flight and dips deeply before rising up. Taxonomy This species has sometimes been lumped along with the yellow-spotted petronia ('' Petronia pyrgita'') of Africa. Curr ...

Passeridae
Old World sparrows are a group of small passerine birds forming the family Passeridae. They are also known as true sparrows, a name also used for a particular genus of the family, ''Passer''. They are distinct from both the New World sparrows, in the family Passerellidae, and from a few other birds sharing their name, such as the Java sparrow of the family Estrildidae. Many species nest on buildings and the house and Eurasian tree sparrows, in particular, inhabit cities in large numbers. They are primarily seed-eaters, though they also consume small insects. Some species scavenge for food around cities and, like gulls or pigeons, will eat small quantities of a diversity of items. Description Generally, Old World sparrows are small, plump, brown and grey birds with short tails and stubby, powerful beaks. The differences between sparrow species can be subtle. Members of this family range in size from the chestnut sparrow (''Passer eminibey''), at and , to the parrot-billed spa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petronia Superciliaris
The yellow-throated bush sparrow (''Gymnoris superciliaris''), also known as the yellow-throated petronia, is a species of bird in the sparrow family Passeridae. It is found in south-central and southern Africa in its natural habitats of subtropical or tropical dry forests, dry savanna A savanna or savannah is a mixed woodland- grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to ..., and subtropical or tropical dry shrubland.

Petronia Brachydactyla
The pale rockfinch or pale rock sparrow (''Carpospiza brachydactyla'') is a small sparrow found in the Middle East and Central Asia. It is the only member of the genus ''Carpospiza''. Some authorities include it in the genus ''Petronia''. Others have placed it in the finch family due to some similarities in behaviour and form, but the anatomy of its tongue exhibits characteristic sparrow features. The range of pale rockfinch extends from eastern Turkey to Afghanistan, and south into the Arabian Peninsula and northern Africa as far as Ethiopia. Its natural habitats are subtropical or tropical dry shrubland and temperate grassland. The breeding pattern of the pale rock sparrow is associated with specific aspects of habitat. Presence of this species is associated with temperature, grasshopper and beetle abundance, whereas density is associated with available habitat. Since available habitat plays a role on the density of pale rockfinches, rapidly growing villages and cultivati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Sparrow
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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petronia Dentata
The Sahel bush sparrow (''Gymnoris dentata'') or bush petronia, is a species of bird in the family Passeridae. It is found in Africa from Mauritania to Guinea and east to Eritrea and the south-western Arabian Peninsula in its natural habitats of dry savanna and subtropical or tropical dry shrubland. Description The Sahel bush sparrow is a small bird with a large, conical beak and a short tail. It grows to a length of about .

Johann Jakob Kaup
Johann Jakob von Kaup (10 April 1803 – 4 July 1873) was a German naturalist. A proponent of natural philosophy, he believed in an innate mathematical order in nature and he attempted biological classifications based on the Quinarian system. Kaup is also known for having coined popular prehistoric taxa like '' Pterosauria'' and ''Machairodus''. Biography He was born at Darmstadt. After studying at Göttingen and Heidelberg he spent two years at Leiden, where his attention was specially devoted to the amphibians and fishes. He then returned to Darmstadt as an assistant in the grand ducal museum, of which in 1840 he became inspector. In 1829 he published ''Skizze zur Entwickelungsgeschichte der europäischen Thierwelt'', in which he regarded the animal world as developed from lower to higher forms, from the amphibians through the birds to the beasts of prey; but subsequently he repudiated this work as a youthful indiscretion, and on the publication of Darwin's ''Origin of Species' ...

Polyandry
Polyandry (; ) is a form of polygamy in which a woman takes two or more husbands at the same time. Polyandry is contrasted with polygyny, involving one male and two or more females. If a marriage involves a plural number of "husbands and wives" participants of each gender, then it can be called polygamy, group marriage, group or conjoint marriage. In its broadest use, polyandry refers to sexual relations with multiple males within or without marriage. Of the 1,231 societies listed in the 1980 Ethnographic Atlas, 186 were found to be monogamous, 453 had occasional polygyny, 588 had more frequent polygyny, and 4 had polyandry.''Ethnographic Atlas Codebook'' derived from George P. Murdock's ''Ethnographic Atlas'' recording the marital composition of 1,231 societies from 1960 to 1980. Polyandry is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Egg
Bird eggs are laid by the females and range in quantity from one (as in condors) to up to seventeen (the grey partridge). Clutch size may vary latitudinally within a species. Some birds lay eggs even when the eggs have not been fertilized; it is not uncommon for pet owners to find their lone bird nesting on a clutch of infertile eggs, which are sometimes called wind-eggs. Anatomy All bird eggs contain the following components: * The embryo is the immature developing chick * The amnion is a membrane that initially covers the embryo and eventually fills with amniotic fluid, provides the embryo with protection against shock from movement * The allantois helps the embryo obtain oxygen and handles metabolic waste * The chorion, together with the amnion, forms the amniotic sac and encloses the amnion, vitellus, and the embryo * The vitellus, or yolk, is the nutrient-bearing portion of the egg, containing most of its fat, minerals, and many of its proteins and blood vessels * The alb ...
