28-1-2022 MONTE CORONA, VALENCIA - APINE BEE (Bombus terrestris ssp. lusitanicus)
Bombus terrestris, the buff-tailed bumblebee or large earth bumblebee, is one of the most numerous bumblebee species in Europe. It is one of the main species used in greenhouse pollination, and so can be found in many countries and areas where it is not native, such as Tasmania. Moreover, it is a eusocial insect with an overlap of generations, a division of labour, and cooperative brood care. The queen is monogamous which means she mates with only one male. B. terrestris workers learn flower colours and forage efficiently.
B. terrestris is part of the order Hymenoptera, which is composed of ants, bees, and wasps. The family Apidae specifically consists of bees. It is also part of the subfamily Apinae. There are 14 tribe lineages within Apinae, and B. terrestris is in the bumblebee tribe, Bombini. It is in the genus Bombus, which consists entirely of bumblebees, and the subgenus Bombus sensu stricto. This subgenus contains closely related species such as Bombus affinis, Bombus cryptarum, Bombus franklini, Bombus ignitus, Bombus lucorum, Bombus magnus, Bombus occidentalis, and Bombus terricola. There are nine recognized subspecies: B. terrestris africanus, B. terrestris audax, B. terrestris calabricus, B. terrestris canariensis, B. terrestris dalmatinus, B. terrestris lusitanicus, B. terrestris sassaricus, B. terrestris terrestris and B. terrestris xanthopus, each with a distinctive coloration scheme.

28-5-2019 SOMALISA CAMP, ZIMBABWE - LILAC BREASTED ROLLER (Coracias caudatus)
The lilac-breasted roller (Coracias caudatus) is a member of the roller family, Coraciidae, resplendent in a panoply of pastel hues. This African bird is a sight to behold, with its lilac throat and breast, olive crown to mantle, and cheeks of lilac-rufous. The species is further adorned with long, black tail streamers, which juveniles lack. Unofficially, it is considered the national bird of Kenya.
In the field, the lilac-breasted roller is almost unmistakable. Adults boast a lilac throat that deepens into a darker lilac breast, with an olive crown and mantle. The cheeks and ear coverts are a lilac-rufous. Juveniles and immatures can be identified by their lack of tail streamers and a throat and breast of rufous-tawny with broad diffuse buffy-white streaks. The species is not sexually dimorphic, though males may be slightly larger.
The lilac-breasted roller favors open woodland and savanna, typically avoiding treeless expanses. They are often seen perched high, surveying the landscape for prey.
28-5-2019 SOMALISA CAMP, ZIMBABWE - SMITH'S BUSH SQUIRREL (Paraderus Cepapi)

Smith's bush squirrel (Paraxerus cepapi), also known as the yellow-footed squirrel or tree squirrel, is an African bush squirrel which is native to woodlands of the southern Afrotropics.
It is found in Angola, Botswana, the DRCongo, Malawi, Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe. It is a common rodent which is diurnal by nature.
Its total length is 350 mm (14 in), half of which is tail; weight 200 g (7.1 oz). The coat colour varies throughout the region. In the western and arid parts of its range, it is pale grey, and in the eastern localities, more brown. Its head and legs are a rusty colour. Colouration on the chest varies from yellowish to buff in the east, to white in the west. This squirrel's belly is white. These alert and ever busy creatures carry their long tails extended backwards.
Smith's bush squirrels are primarily vegetarian, but like most rodents, they take insect prey and use their front feet to manipulate food items when feeding. They scatter-hoard seeds next to tree trunks or grass tufts, thereby facilitating tree regeneration.

Essentially arboreal animals, they also spend a great deal of time on the ground, foraging for food. When disturbed, Smith's bush squirrels always seek the refuge of trees. At night, territorial family groups nest together in holes in trees. Offspring become sexually mature between six and nine months old, when they are forcibly evicted by the breeding pair. The males are mainly responsible for territorial defense, although females also chase intruders when they care for dependent pups. To promote group cohesion, a common scent is shared by mutual grooming, which is an important facet of the social fibre of this species. Smith's bush squirrels are diligent in their grooming and a mother tree squirrel holds her offspring down with her fore legs while grooming it with licks, nibbles, and scratches with her claws.
A conspicuous feature of their behaviour when under threat is 'mobbing': all the members of the colony make harsh clicking sounds while they flick their tails, building up momentum and gradually getting louder. In some areas, they are solitary, or are found in small family groups; a lone tree squirrel relies on its wits when in danger and always keeps a branch or the trunk of a tree between it and the enemy. Smith's bush squirrels are always alert, and when alarmed, run away with great speed, making for the nearest tree where they lie motionless, flattened against a branch.
28-5-2019 SOMALISA CAMP, ZIMBABWE - SOUTHERN WHITE CROWNED SHRIKE (Eurocephalus angustimens)
%2020.jpg)
The southern white-crowned shrike (Eurocephalus anguitimens) is a species of bird in the family Laniidae. It is found in Angola, Botswana, Mozambique, Namibia, South Africa, and Zimbabwe. Its natural habitats are subtropical or tropical dry forests and dry savannah.
The southern white-crowned shrike grows to a length of about 24 cm (9 in). The sexes are alike; in the adult bird the crown and forehead are white, and the mask is black and extends above and below the eye to the side of the neck. The nape and upper parts are ashy-brown and the wings and tail are dark brown. The underparts are off-white, the upper breast being tinged with buff. The lower belly and vent areas are ashy-brown. The beak is black, the eyes brown and the legs dark brown. Juveniles are similar to adult birds but the crown is slightly mottled and barred and grey rather than white. The chin and throat are white but the remaining parts of the underparts are tinged with ashy brown.

28-5-2019 SOMALISA CAMP, ZIMBABWE - CINAMON BREASTED BUNTING (Emberiza tahapisi)
%2020.jpg)
They weigh between 11.6 and 21 grams with a length of 13-15 centimeters. Although plumage differs between juveniles, males, and females, cinnamon-breasted buntings can be identified by their striped head and cinnamon brown underparts. Males have black and white stripes whereas the female stripes are less dark and browner in color. The throat patch is uniformly black on males but smaller, grayish, and densely blotched on females. Juveniles are similar to females but with buffier head stripes and a paler, browner throat. After the breeding season, juveniles moult partially and adults moult completely so all primaries and secondaries are the same age.
Cinnamon-breasted bunting songs are composed of short, high-pitched, rapid trills. Males are known to have eight distinct songs with 40 discrete syllables. Song similarity decreases with distance between local populations but all end with a characteristic final whistle syllable. Individuals perform songs from elevated positions such as from trees, bushes, or rocks.

28-5-2019 SOMALISA CAMP, ZIMBABWE - WAHLBERG STRIPED SKINK (Trachylepis striata ssp. wahlbergi)
Trachylepis wahlbergii, also known commonly as Wahlberg's striped skink, is a species of lizard in the family Scincidae. The species is native to Southern Africa.
Trachylepis wahlbergii has been considered a subspecies of Trachylepis striata. Whether T. wahlbergii is truly distinct from T. striata is not fully settled.
T. wahlbergii occurs in southern Angola, northern Botswana, northern Namibia, western Mozambique, Zambia, and northern, western and southern Zimbabwe.
The specific name, wahlbergi, is in honour of Swedish Naturalist Johan August Wahlberg.
T. wahlbergii is viviparous.
