Pygmy Falcon
The African pygmy falcon (''Polihierax semitorquatus'')—or simply pygmy falcon—is a diminutive raptor native to eastern and southern Africa. It is the sole species in its monotypic genus, ''Polihierax''. The pygmy falcon is the smallest bird of prey on the African continent, and among the smallest raptors on earth; only the Asian falconets (of the genus ''Microhierax'') are smaller, weighing roughly 30-40 grams less and measuring about 5 cm shorter from head-to-tail. Description Adult pygmy falcons are in length and in weight. These birds are white-bellied, extending up to the face, with males having grey on their backsides, and females have a chestnut back. There are white "eye spots" on the nape. Juveniles have a brown back, duller than adult females, with a rufous wash on the breast.

Birds Of Prey Of Sub-Saharan Africa
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kalahari Tree Skink
The Kalahari tree skink (''Trachylepis spilogaster''), or spiny mabuya, is a species of lizard in the skink family (Scincidae). The species is endemic to southern Africa, including Namibia, South Africa, western Botswana, and southern Angola. Habitat Kalahari tree skinks have been found to live around trees that contain the large colonial nests of the sociable weaver The sociable weaver (''Philetairus socius'') is a species of bird in the weaver family, endemic to Southern Africa. It is the only species in its genus ''Philetairus''. It is found in South Africa, Namibia, and Botswana, but its range is cente .... Their numbers are higher in these areas despite a known predator of skinks, the pygmy falcon, also nesting in these trees. It is theorized that the increased opportunity for places of refuge outweigh the risk of predation. Skinks found on colony trees have learned to eavesdrop on sociable weavers to warn of approaching pygmy falcons. References spilogaster Sk ...

Sociable Weaver
The sociable weaver (''Philetairus socius'') is a species of bird in the weaver family, endemic to Southern Africa. It is the only species in its genus ''Philetairus''. It is found in South Africa, Namibia, and Botswana, but its range is centered within the Northern Cape Province of South Africa. The species builds large, compound, community nests, a rarity among birds. These nests are perhaps the most spectacular structure built by any bird. Taxonomy and systematics The sociable weaver was first described by ornithologist John Latham in 1790. Alternative names include the common social weaver, common social-weaver, and social weaver. Formerly, four subspecies were recognised, but the species is now considered monotypic. The sociable weaver is the only extant species in the genus ''Philetairus''. Phylogeny Based on a 2017 DNA-analysis, ''P. socius'' belongs to the group of sparrow weavers (subfamily Plocepasserinae) and is most related to the genus ''Pseudonigrita''. The ...

El Niño–Southern Oscillation
El Niño–Southern Oscillation (ENSO) is a global climate phenomenon that emerges from variation in winds and sea surface temperatures over the tropical Pacific Ocean. Those variations have an irregular pattern but do have some semblance of cycles. The occurrence of ENSO is not predictable. It affects the climate of much of the tropics and subtropics, and has links (Teleconnection, teleconnections) to higher-latitude regions of the world. The warming phase of the sea surface temperature is known as "El Niño" and the cooling phase as "La Niña". The Southern Oscillation is the accompanying atmospheric oscillation, which is coupled with the sea temperature change. El Niño is associated with higher than normal air sea level pressure over Indonesia, Australia and across the Indian Ocean to the Atlantic Ocean, Atlantic. La Niña has roughly the reverse pattern: high pressure over the central and eastern Pacific and lower pressure through much of the rest of the tropics and subtrop ...
