30-6-2018 MONTE CORONA, VALENCIA - SPOTTED FLYCATCHER (Muscicapa striata)
The Spotted Flycatcher, Muscicapa striata, is a modestly adorned yet charming small passerine bird belonging to the Old World flycatcher family. It is a migratory species, breeding across Europe and the Palearctic as far as Siberia, and spending the winter months in Africa and southwestern Asia. Despite its widespread presence, there is concern over its decline in certain areas.
Adult Spotted Flycatchers possess grey-brown upperparts and a somewhat pallid underbelly. Their crown and breast are streaked, which is the origin of their common name. They have short, black legs and a black bill shaped to suit their insectivorous diet. Juveniles can be distinguished by their browner plumage and the presence of spots on their upperparts.
These birds favor deciduous woodlands, parks, and gardens, particularly those with open spaces amidst trees.
The Spotted Flycatcher has a broad breeding range, extending from Europe to western Siberia and northwest Africa. During the non-breeding season, they migrate to southern Africa.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - RED TAILED HAWK (Buteo jamaicensis)
The Red-tailed Hawk (Buteo jamaicensis) is a robust bird of prey, one of the most familiar hawks in North America. This species exhibits a broad range of plumage variations, with 14 recognized subspecies differing in color and range. The Red-tailed Hawk is a large raptor, weighing between 690 to 1,600 grams (1.5 to 3.5 pounds), with a length of 45–65 centimeters (18–26 inches) and a wingspan of 110–141 centimeters (3 feet 7 inches – 4 feet 8 inches). Females are typically about 25% heavier than males. The species is known for its brick-red tail, which gives it its common name.
Adult Red-tailed Hawks have a rich brown upper body and pale underparts, with a streaked belly and a dark bar between the shoulder and wrist. The tail is usually a rich red color above and pale below, with a black subterminal band. Immature birds have a brown tail with dark bars and may lack the red coloration. The bird's beak is short and dark, and the legs and feet are yellow. In flight, the broad, rounded wings and short, wide tail are characteristic.
Red-tailed Hawks are highly adaptable and can be found in a variety of habitats, including deserts, grasslands, forests, agricultural fields, and urban areas. They prefer open areas with high perching sites from which they can survey their territory.
This species has a vast range, breeding from Alaska and northern Canada down through the United States to Panama and the West Indies. It is absent from the high Arctic and the most densely forested parts of the Amazon.
Red-tailed Hawks are known for their soaring flight, often seen circling high above the ground. They are territorial and can be aggressive, especially during the breeding season. These hawks are solitary hunters but may form pairs or small family groups.

29-6-2018 MONTE CORONA, VALENCIA - STRIPED GRAYLING BUTTERFLY (Hipparchia fidia)
Hipparchia fidia, the striped grayling, is a butterfly of the family Nymphalidae. It is found on the Iberian Peninsula, the Balearic Islands and in south-eastern France and the bordering parts of Italy and North Africa.
S. fidia L. (44 d). Above similar to the preceding [ fatua ], but the underside much more variegated and brighter: the ocelli of the forewing large, broadly bordered with yellow, there being before them white smears which are proximally bordered by a black line.
On the underside of the hindwing the exterior black discal line projects behind the apex of the cell as a broad tooth; it is externally broadly white and beyond it there are moreover strong white smears extending towards the distal margin.
The wingspan is 48–56 millimetres (1.9–2.2 in).
The butterflies fly from July to August depending on the location.
The larvae feed on various types of grass.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - SPOTTED EAGLE OWL (Bubo africanus)
%2020.jpg)
The Spotted Eagle-Owl, known scientifically as Bubo africanus, is a medium-sized owl and one of the more diminutive members of the eagle owl family. It measures approximately 45 cm (18 inches) in length and weighs between 454 to 907 grams (1.0 to 2.0 pounds), with a wingspan ranging from 100 to 140 cm (39 to 55 inches). This species is distinguished by its off-white to pale ochre facial disk and striking yellow eyes. It boasts prominent ear-tufts, a dusky brown upper body, and off-white lower parts adorned with brown bars.
When attempting to identify the Spotted Eagle-Owl, look for its prominent ear-tufts and the distinctive barring on its chest and belly. The yellow eyes set against the pale facial disk are also key identification features. Its flight is silent and buoyant, typical of owl species.
The Spotted Eagle-Owl is versatile in its choice of habitat. It is commonly found in southern Africa, thriving in both thorn savanna and suburban gardens. It has a particular fondness for rocky outcrops and open areas, where it often roosts on the ground or in tree crowns.
This owl is widespread across sub-Saharan Africa and the Arabian Peninsula. It is the most prevalent owl species in southern Africa and is frequently encountered in urban areas, living in close proximity to human settlements.
The Spotted Eagle-Owl is a solitary and nocturnal bird, known for its typical eagle-owl hoots. The male's call consists of two hoots, "Hooo hooopoooo," while the female responds with three, "Hooo hoo hooo." The young communicate with hisses and beak snaps when threatened. This species is also known to bathe, often seen during summer thunderstorms with wings spread.
The male's two-part hoot and the female's three-part response are characteristic of this species. The young make a rasping noise when hungry, which can be heard over long distances.
Spotted Eagle-Owls are monogamous and breed from late July to early February. They often nest on the ground or in large cavities, including man-made structures. The female lays two to four eggs and incubates them for about 32 days. Owlets leave the nest at around five weeks old and are flight-capable at seven weeks, though they remain dependent on their parents for several weeks thereafter.
The diet of the Spotted Eagle-Owl primarily includes rodents, small mammals, birds, insects, and reptiles. It has a preference for small mammals like rodents and shrews. The owl often swallows prey whole and regurgitates indigestible parts as pellets. It is a generalist feeder and may move to new hunting grounds when prey becomes scarce.
The Spotted Eagle-Owl is classified as Least Concern on the IUCN Red List. It is a common species within its range, but it faces threats from car collisions, electric wires, persecution, secondary poisoning, and parasite infections. Conservation efforts include specialized care for captive owlets and release methods for reintegration into the wild. It is illegal to capture or keep indigenous owls in South Africa without a permit.

25-3-2018 CAPE TOWN, SOUTH AFRICA - EGYPTIAN GOOSE (Alopochen aegyptiaca)
The Egyptian goose is largely terrestrial, capable of perching on trees and buildings. It is known for its aggressive territorial behavior, especially during breeding season, and is not hesitant to engage in aerial combat with intruders. The species is monogamous, with both parents caring for their offspring.
The male's call is a subdued, hoarse quack, becoming louder and more rapid when agitated, resembling a steam engine. The female's quack is raucous and frequently heard, particularly when defending her young.
Nesting occurs in a variety of locations, with a preference for holes in mature trees. Both parents incubate the eggs, and the young are capable of foraging for themselves shortly after hatching.
Egyptian geese primarily consume seeds, leaves, grasses, and plant stems. They may also eat small animals such as locusts and worms. Goslings initially feed on small aquatic invertebrates before transitioning to grazing.
The Egyptian goose is classified as Least Concern by the IUCN, indicating a stable population. However, in regions where it has been introduced, it is considered invasive and may pose a threat to native species.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - SOUTHERN GROUND HORNBILL (Bucorvus leadbeateri)
The Southern Ground Hornbill (Bucorvus leadbeateri), formerly known as Bucorvus cafer, is a remarkable bird, the largest in the hornbill order and found exclusively within Africa. This majestic creature, with a length ranging from 90 to 129 cm and a wingspan of 1.2 to 1.8 meters, is a sight to behold. The males, larger than the females, can weigh between 3.5 to 6.2 kilograms, while females range from 2.2 to 4.6 kilograms. They are predominantly black with striking red patches of bare skin on the face and throat, which serve to keep dust from their eyes while foraging. In flight, the white tips of their wings are distinctly visible. The beak is robust, black, and slightly curved, with a casque more pronounced in males. Females are identified by their violet-blue throat skin, while juveniles have a paler, greyish patch instead of the vibrant red.
To identify the Southern Ground Hornbill, look for its large size, black plumage, and the vivid red or violet-blue skin on the throat. The male's throat is a pure red, while the female's is deep violet-blue. Juveniles can be recognized by their duller grey throat patch. In flight, the white primary feathers are a key distinguishing feature.
The Southern Ground Hornbill is found in woodlands and savannas, requiring a habitat with large trees for nesting and short grass for foraging.
This species ranges from Kenya to South Africa, with its presence also noted in northern Namibia and Angola to southern Zimbabwe and Burundi.
Living in groups of 5 to 10, these birds are apex predators and play a crucial ecological role. They forage on the ground, hunting a variety of prey from insects to small mammals. They are known for their loud, chorus-like calls that can be heard over great distances, serving as a means of maintaining their territory.
The Southern Ground Hornbill's calls are a distinctive aspect of their behavior, used for communication and territorial purposes. These calls can be heard up to 3 kilometers away.
Breeding pairs are assisted by at least two other birds, and experience as helpers is essential for successful rearing of young. They reach sexual maturity around 4-6 years of age and start breeding at about 10 years. Nesting typically occurs in high tree cavities or cliff face rock holes. They lay one to three eggs, but only one chick is usually reared to fledging.
The Abyssinian Ground Hornbill (B. abyssinicus) is similar but can be distinguished by its size and range.
Southern Ground Hornbills are carnivorous, feeding on reptiles, frogs, snails, insects, and mammals up to the size of hares. They forage on the ground and rarely drink water.
The IUCN lists the Southern Ground Hornbill as Vulnerable globally, with an Endangered status in South Africa, Lesotho, Namibia, and Eswatini. Their numbers are declining due to habitat destruction, persecution, and other factors. Conservation efforts include habitat preservation and captive breeding programs.
16-4-2021 MANDINA LODGE, GAMBIA - VIOLET TURACO (Musophaga violacea)
The violet turaco, also known as the violaceous plantain eater (Musophaga violacea), is a large turaco, a group of African otidimorphae.
These are unmistakable birds, but shy and often inconspicuous in the treetops. They are approximately 48 cm (19 in) long, including a long tail and a 4 cm (1.6 in) bill. They boast a winglength of 21 cm (8.3 in) and weigh approximately 360 g. The plumage is glossy violet, except for the yellow forehead, chestnut crown and white ear coverts; the bill is thick and red. In flight, the violet turaco's crimson primary flight feathers contrast with the violet plumage. The red colour in the wings is typical of turacos.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - BLACK KITE (Milvus migrans)
The black kite was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1770. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Falco migrans in his catalogue of the Planches Enluminées. The type locality is France. The current genus Milvus was erected by the French naturalist Bernard Germain de Lacépède in 1799. Milvus is the Latin word for a red kite; the specific migrans means "migrating" from the Latin migrare "to migrate".
The red kite has been known to hybridize with the black kite (in captivity where both species were kept together, and in the wild on the Cape Verde Islands).
Recent DNA studies suggest that the yellow-billed African races parasitus and aegyptius differ significantly from black kites in the Eurasian clade, and should be considered a separate allopatric species: yellow-billed kite, M. aegyptius. They occur throughout Africa except for the Congo Basin and the Sahara Desert. There have been some suggestions that the black-eared kite (M. m. lineatus) should be elevated to full species status as M. lineatus, but this is not well supported.
Black kites can be distinguished from red kites by the slightly smaller size, less forked tail (visible in flight), and generally dark plumage without any rufous. The sexes are alike though the male is a little smaller and less aggressive (this is the case in most birds of prey). They weigh on average 735 grams. The upper plumage is brown but the head and neck tend to be paler. The patch behind the eye appears darker. The outer flight feathers are black and the feathers have dark cross bars and are mottled at the base. The lower parts of the body are pale brown, becoming lighter towards the chin. The body feathers have dark shafts giving it a streaked appearance. The cere and gape are yellow, but the bill is black (unlike that of the yellow-billed kite). The legs are yellow and the claws are black. They have a distinctive shrill whistle followed by a rapid whinnying call. Males and females have the same plumage but females are longer than males and have a little larger wingspan. Their wingspan is around 150 cm.
The species is found in Europe, Asia, Africa and Australia. The temperate populations of this kite tend to be migratory while the tropical ones are resident. European and central Asian birds (subspecies M. m. migrans and black-eared kite M. m. lineatus, respectively) are migratory, moving to the tropics in winter, but races in warmer regions such as the Indian M. m. govinda (small Indian/pariah kite), or the Australasian M. m. affinis (fork-tailed kite), are resident. In some areas such as in the United Kingdom, the black kite occurs only as a wanderer on migration. These birds are usually of the nominate race, but in November 2006 a juvenile of the eastern lineatus, not previously recorded in western Europe, was found in Lincolnshire.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - SECRETARY BIRD (Sagittarius serpentarius)
The Secretarybird (Sagittarius serpentarius) is a remarkable bird of prey, endemic to the African continent. It stands out with its eagle-like body perched upon long, crane-like legs, reaching heights of up to 1.3 meters (4 feet 3 inches). Both sexes exhibit a similar plumage of predominantly grey feathers, a distinctive flattened dark crest, and a featherless red-orange face. The bird's impressive stature is complemented by black flight feathers and thighs, adding to its striking appearance.
Adult Secretarybirds can be identified by their tall frame, long legs, and unique combination of grey and black plumage. The red-orange face is devoid of feathers, and the eyes are pale brown. In flight, the Secretarybird's long legs trail behind, and its elongated central tail feathers are noticeable. Juveniles differ slightly with yellow facial skin and darker grey down.
The Secretarybird favors open grasslands, savannas, and shrublands, avoiding dense forests and shrubbery that could hinder its ground-based lifestyle. It thrives in areas where the grass is shorter than 0.5 meters (1 foot 8 inches) and is less common in regions with taller grass or hotter climates.
This species is widespread across sub-Saharan Africa, from Senegal to Somalia and down to the Western Cape in South Africa. It is generally non-migratory, though local movements may occur in response to rainfall and prey availability.
Secretarybirds are typically solitary or found in pairs, often roosting in trees. They are known for their deliberate pacing on the ground, where they spend much of their day hunting. These birds are capable of soaring using thermals and can reach altitudes of up to 3,800 meters (12,500 feet).
While generally silent, Secretarybirds can produce a deep, guttural croaking sound during nuptial displays or when at the nest. They may also emit high-pitched croaks when alarmed, and chicks have a distinct call during their first month.
Breeding can occur at any time of year, with a preference for the late dry season. Secretarybirds build large, flat nests atop thorny trees, where they lay a clutch of one to three eggs. Both parents incubate the eggs and care for the chicks, which fledge after about 75 to 80 days.

The Secretarybird is a terrestrial hunter, preying on insects, small vertebrates, and occasionally larger mammals. It is known for its method of stomping on prey to kill or immobilize it. Snakes, including venomous species, are also part of its diet, although their importance has been historically overstated.
28-6-2018 CAMI LES FONTS OLIVA, VALENCIA - SPOTTED FLYCATCHER (Muscicapa striata)
%2020.jpg)
The spotted flycatcher (Muscicapa striata ) is a small passerine bird in the Old World flycatcher family. It breeds in most of Europe and in the Palearctic to Siberia, and is migratory, wintering in Africa and south western Asia. It is declining in parts of its range.
This is an undistinguished looking bird with long wings and tail. The adults have grey-brown upperparts and whitish underparts, with a streaked crown and breast, giving rise to the bird's common name. The legs are short and black, and the bill is black and has the broad but pointed shape typical of aerial insectivores. Juveniles are browner than adults and have spots on the upperparts.

28-6-2018 OLIVA PLAYA, VALENCIA - SEA DAFFODIL (Pancratium maritimum)
Pancratium maritimum, or sea daffodil, is a species of bulbous plant native to both sides of the Mediterranean region and Black Sea from Portugal, Morocco and the Canary Islands east to Turkey, Syria, Israel and the Caucasus. In the parts of its range on the south Bulgarian and north Turkish and Georgian coasts of Black Sea. It is also naturalized in southern California, Bermuda and the Azores.
Pancratium maritimum grows on beaches and coastal sand dunes, often with much of the leaves and scapes buried in the sand. Other vernacular names are sea lily, sand daffodil, sand lily and lily of St. Nicholas, (although it is not a true lily). The specific epithet maritimum means "of the sea".
Pancratium maritimum is a bulbous perennial with a long neck and glaucous, broadly linear leaves, evergreen, but the leaves often die back during hot summers. Scape to 40 centimetres (16 in). Flowers 3–15 in an umbel, up to 15 cm (6 in) long, white. Corona two-thirds as long as the tepals. The flowers have a pleasing, exotic and very subtle lily scent, which only becomes apparent during still, windless summer nights that allow the delicate fragrance to become perceptible. Flowering is from August to October.

The flowers have a pleasing, exotic and very subtle lily scent, which only becomes apparent during still, windless summer nights that allow the delicate fragrance to become perceptible. Flowering is from August to October.
Pancratium maritimum is pollinated by a hawk-moth named Agrius convolvuli. These insects visit the flower only when the speed of the wind is under 2 metres per second (6.6 ft/s). Even if the species is pollinated in an artificial way during windy weather the pollination is not effective. Pancratium maritimum is not receptive to its own pollen and must be cross-pollinated.
Easily grown but requires a very sunny position and a very well drained, sandy soil. Needs hot summers to induce flowering and is often a shy bloomer in cooler climates. Hardy to USDA zone 8. Tolerates temperatures down to about −5 °C (23 °F). Propagation by seeds or division after flowering. Seedlings may flower in their third or fourth year.
The Hebrew name for the flower is חבצלת החוף (khavatselet ha-Khof), closely related to the rose of Sharon (khavatselet ha-Sharon – חבצלת השרון) mentioned in the Song of Solomon. Since the plant grows on the Sharon plain of the coast of the Mediterranean Sea, it is suggested the biblical passage may refer to this flower.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - DOMESTIC GUINEA PIG (Cavia porcellus)
The guinea pig or domestic guinea pig (Cavia porcellus), also known as the cavy or domestic cavy (/ˈkeɪvi/ KAY-vee), is a species of rodent belonging to the genus Cavia, family Caviidae. Breeders tend to use the name "cavy" for the animal, but "guinea pig" is more commonly used in scientific and laboratory contexts. Despite their name, guinea pigs are not native to Guinea, nor are they closely related to pigs. Instead, they originated in the Andes region of South America, where wild guinea pigs can still be found today. Studies based on biochemistry and DNA hybridization suggest they are domesticated animals that do not exist naturally in the wild, but are descendants of a closely related cavy species such as C. tschudii. Originally, they were domesticated as livestock (source of meat) in the Andean region and are still consumed in some parts of the world.
In Western society, the guinea pig has enjoyed widespread popularity as a pet since its introduction to Europe and North America by European traders in the 16th century. Their docile nature, friendly responsiveness to handling and feeding, and the relative ease of caring for them have continued to make guinea pigs a popular choice of household pets. Consequently, organizations devoted to the competitive breeding of guinea pigs have been formed worldwide. Through artificial selection, many specialized breeds with varying coat colors and textures have been selected by breeders.
Livestock breeds of guinea pig play an important role in folk culture for many indigenous Andean peoples, especially as a food source. They are not only used in folk medicine and in community religious ceremonies but also raised for their meat. Guinea pigs are an important culinary staple in the Andes Mountains, where it is known as cuy. Lately, marketers tried to increase their consumption outside South America.
Biological experimentation on domestic guinea pigs has been carried out since the 17th century. The animals were used so frequently as model organisms in the 19th and 20th centuries that the epithet guinea pig came into use to describe a human test subject. Since that time, they have mainly been replaced by other rodents, such as mice and rats. However, they are still used in research, primarily as models to study such human medical conditions as juvenile diabetes, tuberculosis, scurvy (like humans, they require dietary intake of vitamin C), and pregnancy complications.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - TIMNEH PARROT (Psittacus erithacus ssp. timneh)
The Timneh parrot (Psittacus timneh), also known as the Timneh grey parrot or Timneh African grey parrot, is a West African parrot. Formerly classified as a subspecies of the grey parrot Psittacus erithacus timneh, it is now considered a full species Psittacus timneh. In aviculture, it is often referred to by the initials TAG and is commonly kept as a companion parrot.
The Timneh parrot was formally described in 1844 by the British zoologist and collector Louis Fraser. He coined the binomial name Psittacus timneh and specified the type locality as "Timneh country, Sierra Leone".[2] The Temne are an ethnic group that are predominantly found in the Northern Province of Sierra Leone. The Timneh parrot was formerly classified as a subspecies of the grey parrot but is now treated as a separate species based on the results of a genetic and morphological study published in 2007.
The Timneh parrot is endemic to the western parts of the moist Upper Guinean forests and bordering savannas of West Africa from Guinea-Bissau, Sierra Leone and southern Mali eastwards to at least 70 km east of the Bandama River in Ivory Coast. There is no natural range overlap with the grey parrot although, as both taxa are common in aviculture, escapes can occur and hybridization between greys and Timnehs has been observed in captivity. The birds typically inhabit dense forest, but are also seen at forest edges and in clearings, in gallery forest along waterways, savanna woodland and mangroves. Though they are sometimes found in cultivated areas and gardens, it is not clear whether these habitats contain self-sustaining populations; the birds may make seasonal movements out of the driest parts of their range in the dry season.

25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - SOUTHERN YELLOW BILLED HORNBILL (Tockus leucomelas ssp parvior)
The Southern Yellow-billed Hornbill, known scientifically as Tockus leucomelas, is a medium-sized bird, with a length ranging from 48 to 60 centimeters and a weight between 132 and 242 grams. Its most striking feature is the long, down-curved yellow beak, which is disproportionately large compared to its body, making up to one-sixth of its body length. Males boast a longer beak, averaging 90 millimeters, while females have a slightly shorter one, averaging 74 millimeters. The species exhibits sexual dimorphism, with males generally larger than females. The bird's plumage is a combination of white, grey, and black, with the white belly and grey neck contrasting against the black back adorned with white spots and stripes. The eyes are typically yellow, though brown variations exist, and the skin around the eyes and malar stripe is pinkish.
To identify the Southern Yellow-billed Hornbill, look for the long yellow beak and modest-sized casque that covers almost the entire length of the beak in males. The bird's white belly, grey neck with spots, and black back with white markings are also distinctive. The male's larger size and longer beak are reliable indicators for sex differentiation in the field.
This hornbill species is a common and widespread resident of the dry thornveldt and broad-leafed woodlands, often seen along roads and watercourses. They show a preference for acacia and broadleaved woodlands when available.
The Southern Yellow-billed Hornbill is near-endemic to the dry savannas of southern Africa, with its range extending from Angola and Namibia in the west to Mozambique and KwaZulu-Natal in the east, including Botswana, Zimbabwe, and northern South Africa.
Active during the day, these birds are often solitary, but may form couples or small groups, especially during breeding or nesting seasons, or when local migration occurs during the dry season. They are ground foragers, not digging but rather overturning debris to find food. They are sedentary but may roam in search of sustenance during dry spells. Monogamous pairs defend their territories with elaborate displays.
The Southern Yellow-billed Hornbill's vocal repertoire includes a piercing cry, whistles, grunts, and cackles. These calls are used for territory demarcation and long-distance communication, often accompanied by physical displays.
Their diet consists mainly of arthropods like termites, beetles, larvae, grasshoppers, and caterpillars, supplemented by small mammals, berries, fruits, nuts, and eggs from other species. They use their beak as forceps to grasp and toss food into their throat, with serrated inner edges aiding in crushing and fragmenting their prey.
Breeding coincides with the onset of the rainy season, varying regionally. Courtship involves feeding, mutual preening, copulation, and nest prospecting. Nests are made in natural cavities, with the female sealing herself inside during incubation. Eggs are white and oval, with 2-6 per clutch, hatching after about 24 days. Chicks are born naked and are fed by both parents until they are ready to fledge.
The unique appearance of hornbills has led to their significant role in various cultural beliefs. Some indigenous tribes consider them sacred, while others may hunt them for food, traditional medicine, or ritualistic purposes.
The IUCN Red List classifies the Southern Yellow-billed Hornbill as Least Concern, indicating that the species does not currently face a significant risk of extinction.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - NANDAY PARAKEET (Aratinga nenday)
%2030.jpg)
The Nanday Parakeet, also known as the Black-hooded Parakeet or Nanday Conure, is a medium-small parrot, resplendent in its mostly green plumage. It measures between 27 to 30 centimeters in length and weighs approximately 140 grams. The bird is instantly recognizable by its striking black facial mask and beak, a feature that has inspired its name. Its wings boast black, trailing flight feathers, and its long tail is elegantly edged with blue. The upper chest of this parrot is a bluish-green, transitioning to a paler green on the lower chest, while red feathers adorn the thighs.
When attempting to identify the Nanday Parakeet, look for its distinctive black mask and beak, which contrast sharply with its vibrant green body. The trailing edges of the wings are black, and the tail is long with a blue tip. The bird's upper chest is bluish-green, and the lower chest is paler. Red feathers on the thighs are another key characteristic to observe.
In the wild, Nanday Parakeets are found in scrub forests and forest clearings, often near human settlements. They are also known to inhabit open savannahs, pastures, and stockyards, where they can sometimes be considered pests.
%2031.jpg)
This species is native to South America, with its range extending from southeast Bolivia to southwest Brazil, central Paraguay, and northern Argentina, particularly in the Pantanal region. Escaped or released caged birds have established self-sustaining populations in various locations, including Tenerife and several areas in the United States such as Los Angeles, San Antonio, and Florida.
Nanday Parakeets are social birds that form large communal roosts outside of the breeding season. They are known to feed on a variety of seeds, fruits, palm nuts, berries, flowers, and buds. In urban environments, they may also visit bird feeders.
During the breeding season, these parakeets typically nest in tree cavities. Females lay clutches of three to four eggs, and after the young are raised, the birds regroup into communal roosts.
The diet of the Nanday Parakeet consists of seeds, fruits, palm nuts, berries, flowers, and buds. They are known to adapt to available food sources in their environment, including visiting bird feeders in urban areas.
The Nanday Parakeet is currently listed as Least Concern on the IUCN Red List, indicating that it is not at immediate risk of population decline or extinction.
25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - SCARLET IBIS (Eudocimus ruber)
The Scarlet Ibis (Eudocimus ruber), sometimes referred to as the red ibis, is a strikingly colored member of the ibis family, Threskiornithidae. Its brilliant scarlet plumage sets it apart from other species, making it an unmistakable sight in its native habitats. This bird is one of the two national birds of Trinidad and Tobago and is celebrated in the region's culture and folklore.
Adult Scarlet Ibises are predominantly scarlet, with the intensity of color varying slightly across their feathers. The tips of their wings are the only exception, displaying a rich inky black or dark blue on the longest primaries. The bill and feet are generally red, though the bill may darken towards the end. Juveniles start out grey, brown, and white, gradually acquiring the adult's scarlet hue as they mature. Adults measure 55–63 centimeters in length, with a wingspan of approximately 54 centimeters.
Scarlet Ibises favor wetlands and marshy environments, including mudflats, shorelines, and rainforests. They are often found in areas with abundant water sources, such as swamps, where they can forage for food.
This species has a broad range across South America and the Caribbean. It is native to Brazil, Colombia, French Guiana, Guyana, Suriname, Venezuela, and several Caribbean islands. The Scarlet Ibis is also known to inhabit the coastal regions of various Brazilian states.
Scarlet Ibises are strong fliers, migrating in flocks that adopt the classic V formation. They are sociable birds, living in groups and nesting in close proximity to one another. These birds are also known for their aggressive behavior when foraging, often dominating over other species to secure food.
The Scarlet Ibis is relatively quiet, with its vocalizations typically consisting of low-pitched honking sounds.
Mating pairs construct simple stick nests in trees, often above water for protection. They lay clutches of three to five eggs, which incubate for about 19–23 days. Both parents share in the care of the young.
The American White Ibis (Eudocimus albus) is the closest relative and is sometimes considered conspecific. However, the Scarlet Ibis is distinguished by its vibrant red coloration.
The diet of the Scarlet Ibis is varied, including insects, crustaceans, and other small prey. They use their long, curved bills to probe for food in mud and under plants. Their red coloration is due to a diet rich in red crustaceans, which contain the carotenoid astaxanthin.
The Scarlet Ibis is classified as Least Concern by the IUCN. While some local populations are declining, the species as a whole is not currently considered threatened.
The Scarlet Ibis holds significant cultural importance in Trinidad and Tobago, where it is a national bird and features on the country's coat of arms. It is also a focal species for conservation efforts in the region, particularly within the Caroni Swamp wildlife sanctuary.
27-6-2018 POTRIES, VALENCIA - EPAULET SKIMMER DRAGONFLY (FEMALE) (Orthetrum chrysostigma)
Orthetrum chrysostigma, the epaulet skimmer, is a species of dragonfly in the family Libellulidae. It is found in Algeria, Angola, Benin, Botswana, Burkina Faso, Cameroon, Central African Republic, Chad, the Democratic Republic of the Congo, Ivory Coast, Egypt, Equatorial Guinea, Ethiopia, Gambia, Ghana, Guinea, Kenya, Liberia, Libya, Malawi, Mali, Mauritania, Morocco, Mozambique, Namibia, Niger, Nigeria, Senegal, Sierra Leone, Somalia, South Africa, Sudan, Tanzania, Togo, Uganda, Zambia, Zimbabwe, and possibly Burundi as well as Canary Islands, Israel, and Portugal. It was recorded in the Maltese Islands in 2010. One was also spotted in Tel Aviv, Israel in August 2022.
Its natural habitats are subtropical or tropical moist lowland forests, dry savanna, moist savanna, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, rivers, intermittent rivers, shrub-dominated wetlands, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, and freshwater springs. The adults prey on various flying insects. The bodies of adult males are blue, and those of young and females are yellow and brown.
Very widespread and occurs virtually throughout Africa, including North Africa. It also occurs in parts of Southern Europe and the Middle East. In South Africa it occurs virtually throughout, but is scarce in the dry central regions.
The Epaulet Skimmer is a southern European and African dragonfly. A little similar to the Keeled Skimmer of the UK, it has a narrow elongated body with central raised "keel". Above is the attractive pale blue male with turquoise eyes, but the "epaulet" marking on the thorax that gives it its name is not often clear and darkens with age.
27-6-2018 MONTE CORONA, VALENCIA - LARGE WALL BROWN BUTTERFLY (Lasiommata maera)
Lasiommata maera, the large wall brown, is a butterfly in the family Nymphalidae.
The species is common in continental Europe. It is also present in the Urals, south western Siberia, Asia Minor, Syria, Iran, Central Asia and the Himalayas. It is absent from the United Kingdom. Its preferred habitats are edges of the forest, unmanaged clearings on forested areas, rocky dry areas and stony slopes, at an elevation of 0–2,000 metres (0–6,562 ft) above sea level.
Lasiommata maera has a wingspan of 44–56 millimetres (1.7–2.2 in). These large butterflies are quite variable in color and pattern. Usually the upperside is orange in the forewings and mostly brown in the hindwings. The forewings always show a single ocellus, while the hindwings bear two or three ocelli. The underside of the forewings is orange and the underside of the hindwings is marbled with gray brown. This species is quite similar to Lasiommata megera, that is smaller and has paler yellow-orange forewings. Seitz P. maera L. (= adrasta Dup.) (45 d). On an average larger than hiera, more evenly coloured, the black markings of the ground less prominent in the nymotypical form with a sooty brown disc; the forewing of the male more pointed, with longer costal margin and more oblique distal margin; on the underside of the forewing the distal band extends without interruption across the median veins to the hindmargin. The underside of the hindwing has a much purer ground-colour, i. e. there are less clouds and shadows between the various dentate lines which cross the disc.
The apical ocellus has a stronger tendency towardsduplication being usually somewhat distorted obliquely and — at least beneath — bearing two pupils. Between this ocellus and the apex there is nearly always a minute eye-dot, there occurring also often specimens with other accessory ocelli . Moreover, the ocelli of the hindwing are as a rule somewhat larger than in the same sex of hiera — A very large material proves that it is hardly possible to find definite trenchant distinctions , especially if one takes into account the large number of local forms of maera, all the various kinds of pattern and coloration exhibiting a great variability.
The larva eats full-grown grasses, such as Poa annua, Poa bulbosa, Poa pratensis, Festuca ovina, Festuca rubra, Festuca pratensis, Glyceria fluitans, Calamagrostis epigejos, Calamagrostis arundinacea, Calamagrostis varia, Deschampsia flexuosa, Agrostis capillaris, Nardus stricta, Dactylis, Lolium and Hordeum species.
This species has two broods in the northern countries, a single brood in the south. Adults fly from April to September. These butterflies are avid fliers and they are seldom seen in flight in strong wind.
