Malachite Sunbird
The malachite sunbird (''Nectarinia famosa'') is a small nectarivorous bird found from the highlands of Ethiopia southwards to South Africa. They pollinate many flowering plants, particularly those with long corolla tubes, in the Fynbos. Taxonomy The sunbirds are a group of small Old World passerine birds, and are placed within the family Nectariniidae, which is found across Africa, the Middle East and into South-east Asia. Also called green sugarbird. The malachite sunbird has two subspecies. The nominate ''N. f. famosa ''occurs mainly in South Africa, Lesotho and western Eswatini, although its range just extends into southern Namibia and Zimbabwe. ''N. f. cupreonitens'' breeds in the highlands from Ethiopia south to northern Mozambique. Description The breeding male malachite sunbird, which has very long central tail feathers, is 25 cm long, and the shorter-tailed female 15 cm. The adult male is metallic green when breeding, with blackish-green wings with small y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protea
''Protea'' () is a genus of South African flowering plants, also called sugarbushes (Afrikaans: ''suikerbos''). Etymology The genus ''Protea'' was named in 1735 by Carl Linnaeus, possibly after the Greek god Proteus, who could change his form at will, possibly because they have such a wide variety of forms. Linnaeus's genus was formed by merging a number of genera previously published by Herman Boerhaave, although precisely which of Boerhaave's genera were included in Linnaeus's ''Protea'' varied with each of Linnaeus's publications. Taxonomy The family Proteaceae to which ''Protea'' species belong is an ancient one among angiosperms. Evidence from pollen fossils suggests Proteaceae ancestors grew in Gondwana, in the Upper Cretaceous, 75–80 million years ago. The Proteaceae are divided into two subfamilies: the Proteoideae, best represented in southern Africa, and the Grevilleoideae, concentrated in Australia and South America and the other smaller segments of Gondwana that ar ...

Brood Parasite
Brood parasites are animals that rely on others to raise their young. The strategy appears among birds, insects and fish. The brood parasite manipulates a host, either of the same or of another species, to raise its young as if it were its own, usually using egg mimicry, with eggs that resemble the host's. The evolutionary strategy relieves the parasitic parents from the investment of rearing young. This benefit comes at the cost of provoking an evolutionary arms race between parasite and host as they coevolve: many hosts have developed strong defenses against brood parasitism, such as recognizing and ejecting parasitic eggs, or abandoning parasitized nests and starting over. It is less obvious why most hosts do care for parasite nestlings, given that for example cuckoo chicks differ markedly from host chicks in size and appearance. One explanation, the mafia hypothesis, proposes that parasitic adults retaliate by destroying host nests where rejection has occurred; there is ...

Nectar Theft
Nectar robbing is a foraging behavior utilized by some organisms that feed on floral nectar, carried out by feeding from holes bitten in flowers, rather than by entering through the flowers' natural openings. "Nectar robbers" usually feed in this way, avoiding contact with the floral reproductive structures, and therefore do not facilitate plant reproduction via pollination. Because many species that act as pollinators also act as nectar robbers, nectar robbing is considered to be a form of exploitation of plant-pollinator mutualism. While there is variation in the dependency on nectar for robber species, most species rob facultatively. Nectar robbers vary greatly in species diversity and include species of carpenter bees, bumblebees, stingless ''Trigona'' bees, solitary bees, wasps, ants, hummingbirds, and some passerine birds, including flowerpiercers. Nectar robbing mammals include a fruit bat and Swinhoe's striped squirrel, which robs nectar from the ginger plant. History R ...

Strelitzia
''Strelitzia'' is a genus of five species of perennial plants, native to South Africa. It belongs to the plant family Strelitziaceae. The genus is named after Queen Charlotte of the United Kingdom, who was born a princess of the house of Mecklenburg-Strelitz. A common name of the genus is bird of paradise flower/plant, because of a resemblance of its flowers to birds-of-paradise. In South Africa, it is commonly known as a crane flower and is featured on the reverse of the 50-cent coin. It is the floral emblem of the City of Los Angeles; two of the species, '' S. nicolai'' and '' S. reginae'', are frequently grown as houseplants. Description The species ''S. nicolai'' is the largest in the genus, reaching 10 m (33 ft) tall, with stately white and blue flowers; the other species typically reach 2.0 to 3.5 m tall, except ''S. caudata'', which is a tree of a typically smaller size than ''S. nicolai''.

Aloe Ferox
''Aloe ferox'', commonly known as bitter aloe, is a species of flowering plant in the family Asphodelaceae. This woody aloe is indigenous to southern Africa. It is one of several ''Aloe'' species used to make bitter aloes, a purgative medication, and also yields a non-bitter gel that can be used in cosmetics. Description ''Aloe ferox'' is a tall, single-stemmed aloe, that can grow to in height. Its leaves are thick and fleshy, arranged in rosettes, and have reddish-brown spines on the margins with smaller spines on the upper and lower surfaces. The leaf surfaces of young plants are covered in spines; however, as they get taller and less vulnerable to grazing, the leaves begin to lose most of their spines except for those along the leaf margins. Plants in the western part of its natural range tend to keep more of their leaf surface spines. Its flowers are a uniform orange or red, and stand between above the leaves, in multi-branched inflorescences. It is a variable speci ...

Hummingbird
Hummingbirds are birds native to the Americas and comprise the biological family Trochilidae. With about 361 species and 113 genera, they occur from Alaska to Tierra del Fuego, but the vast majority of the species are found in the tropics around the equator. They are small birds, with most species measuring in length. The smallest extant hummingbird species is the bee hummingbird, which weighs less than . The largest hummingbird species is the giant hummingbird, weighing . They are specialized for feeding on flower nectar, but all species also consume flying insects or spiders. Hummingbirds split from their sister group, the swifts and treeswifts, around 42 million years ago. The common ancestor of extant hummingbirds is estimated to have lived 22 million years ago in South America. They are known as hummingbirds because of the humming sound created by their beating wings, which flap at high frequencies audible to humans. They hover in mid-air at rapid wing-flapping rate ...

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] |
