17-11-2018 GANDIA, VALENCIA - EURASIAN BLACKBIRD (MALE) (Turdus merula)

The Common Blackbird, Turdus merula, is a true thrush and a familiar sight in gardens and woodlands. The male is distinguished by its all-black plumage, bright yellow eye-ring, and orange-yellow bill, which darkens slightly during winter. Females and juveniles are more demure in their attire, sporting mainly dark brown feathers.

Adult males are entirely black with the exception of the yellow eye-ring and bill. Females are sooty-brown with a duller bill, and juveniles resemble females but have pale spots on their upperparts. The very young may also exhibit a speckled breast.

The Common Blackbird thrives in a variety of habitats including woodlands with dense undergrowth, gardens, parks, and hedgerows. It shows a preference for deciduous trees and areas with thick vegetation.

This species is widespread across Europe, western Asia, and North Africa. It has also been introduced to Australia and New Zealand. Its range varies from resident populations in the milder regions to partially or fully migratory populations in areas with more severe winters.

The Common Blackbird is territorial, especially during breeding season, with males displaying distinctive threat behaviors to ward off rivals. Outside of breeding season, they can be more sociable, often forming small flocks. The species is known for its adaptability to urban environments, where it may overwinter more readily than in rural settings.

17-11-2018 GANDIA, VALENCIA - BLACK REDSTART (FEMALE) (Phoenicurus ochruros)

The Black Redstart (Phoenicurus ochruros) is a small, charismatic passerine bird, exhibiting a blend of dark and vibrant plumage. Males are distinguished by their dark grey to black upperparts and breast, with a striking orange-red rump and tail. Females and juveniles are more subdued in color, with grey to grey-brown feathers and the same vivid tail coloration that is the hallmark of the species.

Adult males are easily identified by their dark upperparts and black breast, contrasting with the orange-red lower rump and tail. The belly and undertail may vary from blackish-grey to orange-red, depending on the subspecies. Females and juveniles are less conspicuous, with overall greyer tones and a distinctive orange-red rump and tail. The presence of pale fringes on the secondaries forms a whitish wing panel in some subspecies.

The Black Redstart has adapted remarkably to urban environments, often found nesting in crevices or holes within buildings. Originally a dweller of stony mountainous regions, it now thrives in industrial areas with similar structural features.

This species is widely distributed across south and central Europe, Asia, and north-west Africa. It is a resident in milder regions, while populations in the northeast migrate to warmer areas during winter.

The Black Redstart is known for its robin-like movements, including quick ducks of the head and body, and frequent tail flicking. Males possess a rattling song and a tick call, adding to their distinctive presence.

22-4-2018 OKAVANGO DELTA, BOTSWANA - NAMIBIAN GIRAFFE (JUVENILE) (Giraffa camelopardalis ssp. angolensis)

The Angolan giraffe (Giraffa angolensis or Giraffa camelopardalis angolensis or Giraffa giraffa angolensis), also known as the Namibian giraffe or smokey giraffe, is a species or subspecies of giraffe that is found in northern Namibia, south-western Zambia, Botswana, western Zimbabwe and since mid-2023 again in Angola.

A 2009 genetic study on this subspecies suggests the northern Namib Desert and Etosha National Park populations each form a separate subspecies. However, genetic studies based on mitochondrial DNA do not support the division into two subspecies., but could identify giraffes in southern Zimbabwe as the Angolan giraffe, suggesting a further eastward distribution than expected.

This subspecies has large brown blotches with edges that are either somewhat notched or have angular extensions. The spotting pattern extends throughout the legs but not the upper part of the face. The neck and rump patches tend to be fairly small. The subspecies also has a white ear patch.

Home range size of Angolan giraffes was found to be larger in unproductive areas such as the Namib Desert and much smaller in more productive areas such as Lake Manyara National Park. However, that home range size could be affected by abiotic(e.g climate), biotic(e.g forage availability, predator densities) and human influence(e.g population growth).

As far as seasonal movements of giraffes were concerned, they were not as distinctive as those in other giraffe populations around the world. Male giraffe moves longer than female giraffe and also it has longer average daily movement (5.64km compared to 1.87km in 180 days during hot-dry season). 

nds to forage into the mountain during the cold-dry and early hot-dry season. It mainly eats Commiphora for living.

Approximately 13,000 animals are estimated to remain in the wild; and about 20 are kept in zoos.

20-4-2018 OKAVANGO DELTA, BOTSWANA - RATTLING CISTICOLA (Cisticola chiniana)

The Rattling Cisticola, Cisticola chiniana, is a small, sprightly bird belonging to the Cisticolidae family. It is a bird that is native to the diverse landscapes of Africa, south of the equator, and parts of East Africa.

This species is characterized by its streaked appearance and a distinctive rufous cap. When perched, one may notice its tail is typically held upright, and its flight is undulating, which aids in identification.

The Rattling Cisticola thrives in a variety of savanna and scrubland habitats, from arid to moist and upland regions. It has a particular affinity for environments dominated by thorn trees or shrubs, such as those of the genera Dichrostachys. It is also a common sight in miombo and mopane woodlands, as well as the Mozambican coastal plain.

This bird's range extends across a swath of the African continent, including Angola, Botswana, Burundi, Congo, DRC, Eswatini, Ethiopia, Kenya, Malawi, Mozambique, Namibia, Somalia, South Africa, South Sudan, Tanzania, Uganda, Zambia, and Zimbabwe.

The Rattling Cisticola is particularly conspicuous during the summer months, when it can be seen—or more often heard—delivering its strident calls from prominent perches atop trees or bushes.

Its call is a distinctive and repetitive sound that can be transcribed as "chee-chee chichi-chirrrrr," although there is some variation among individuals.

Breeding for the Rattling Cisticola occurs in the wet season, during spring and summer. They construct a ball-shaped nest from coarse grass blades, which is then delicately lined with finer plant material.

The Tinkling Cisticola occupies similar habitats but can be distinguished by its preference for stunted broad-leaved and dry deciduous woodlands on sandy substrates. Various other Cisticola species may be found in marshy areas, while Prinia species may co-occur in some regions.

The Rattling Cisticola is currently listed as Least Concern by the IUCN, indicating that, at present, there are no immediate threats to its population numbers that would warrant a higher level of concern.

16-4-2018 CHOBE NATIONAL PARK, BOTSWANA - BURCHELL'S SANDGROUSE (Pterocles burchelli)

Burchell's sandgrouse (Pterocles burchelli) is a species of bird in the family Pteroclidae. It is found in arid and semi-arid regions of southern Africa. The name of this bird commemorates the English naturalist William John Burchell.

Burchell's sandgrouse is a plump bird about the size of a pigeon with a small head and short legs. The body is light brown, mottled with darker shades and white speckles. In males, the eye is surrounded by bare yellow skin and the cheeks and throat are pale grey. The male grows to about 25 cm (10 in) long and the female is a little smaller.

Burchell's sandgrouse is found in Angola, Namibia, Botswana, Zambia, Zimbabwe and South Africa. It is normally resident but moves about to a limited extent depending on the availability of water and the seeds it mainly eats. It is widespread and common in much of its range. It frequents areas of rough grass and scrub, especially on red Kalahari sand and has been able to extend its range because of the greater availability of water after the sinking of boreholes by farmers.

19-4-2018 OKAVANGO DELTA, BOTSWANA - AFRICAN LION (FEMALE) (Panthera leo)

The lion (Panthera leo) is a large cat of the genus Panthera, native to Africa and India. It has a muscular, broad-chested body; a short, rounded head; round ears; and a dark, hairy tuft at the tip of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called prides. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on medium-sized and large ungulates. The lion is an apex and keystone predator.

The lion inhabits grasslands, savannahs, and shrublands. It is usually more diurnal than other wild cats, but when persecuted, it adapts to being active at night and at twilight. During the Neolithic period, the lion ranged throughout Africa and Eurasia, from Southeast Europe to India, but it has been reduced to fragmented populations in sub-Saharan Africa and one population in western India. It has been listed as Vulnerable on the IUCN Red List since 1996 because populations in African countries have declined by about 43% since the early 1990s. Lion populations are untenable outside designated protected areas. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes for concern.

Lion populations are untenable outside designated protected areas. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes for concern.

One of the most widely recognised animal symbols in human culture, the lion has been extensively depicted in sculptures and paintings, on national flags, and in literature and films. Lions have been kept in menageries since the time of the Roman Empire and have been a key species sought for exhibition in zoological gardens across the world since the late 18th century. Cultural depictions of lions have occurred worldwide, particularly has a symbol of power and royalty.

Among felids, the lion is second only to the tiger in size. The size and weight of adult lions vary across its range and habitats. 

African lions live in scattered populations across sub-Saharan Africa. The lion prefers grassy plains and savannahs, scrub bordering rivers, and open woodlands with bushes. It rarely enters closed forests. On Mount Elgon, the lion has been recorded up to an elevation of 3,600 m (11,800 ft) and close to the snow line on Mount Kenya. Savannahs with an annual rainfall of 300 to 1,500 mm (12 to 59 in) make up the majority of lion habitat in Africa, estimated at 3,390,821 km2 (1,309,203 sq mi) at most, but remnant populations are also present in tropical moist forests in West Africa and montane forests in East Africa. The Asiatic lion now survives only in and around Gir National Park in Gujarat, western India. Its habitat is a mixture of dry savannah forest and very dry, deciduous scrub forest.

16-11-2018 MONTE CORONA, VALENCIA - SPINY TOAD (Bufo spinosus)

The spiny toad, spiny common toad, or giant toad (Bufo spinosus) is a species of toad native to the Iberian Peninsula, southern France, extreme northwestern Italy, and North Africa (Morocco, Algeria, and Tunisia). There is an isolated population in Jersey in the Channel Islands. For much of the 20th century, it was considered either a synonym or a subspecies of common toad Bufo bufo, but it is now classified as a separate species.

These toads feed on a number of invertebrates from earthworms to insects and woodlice.

Adult males measure 58.6–112 mm (2.3–4.4 in) and adult females 65–180 mm (2.6–7.1 in) in snout–vent length.

Distribution: Iberian Peninsula and southwestern France (north to about Caen and about Lyon; an isolated population on the Isle of Jersey (United Kingdom); northwestern Africa in the northern mountains of Morocco, Algeria, and Tunisia.

A relatively large  toad with a total maximum length of about 21cm, though males are rather smaller at 9-10cm and the average female is 15cm. The head is longer than wide, with a short rounded snout, and the area between the eyes is either flat or concave. The tympanum is barely visible, measuring about half the diameter of the eye. The fingers are short, the third being the longest, followed by the the first and then the second and fourth, these latter two being of equal length. There are two tubercles on the palms. The toes are relatively long and flattened.

Timarcha is the only member of the tribe Timarchini.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - WHITE BACKED VULTURE (Gyps africanus)

The White-backed Vulture (Gyps africanus) is a medium-sized vulture, characterized by down feathers on the head and neck, broad wings, and short tail feathers. It boasts a distinctive white neck ruff, with adults displaying a whitish back that contrasts starkly with the rest of their dark plumage. Juveniles present a more uniform dark appearance. This species typically weighs between 4.2 to 7.2 kg, measures 78 to 98 cm in length, and spans a wingspan of 1.96 to 2.25 m.

To identify the white-backed vulture, look for its white neck ruff and the contrasting white back against dark plumage in adults. Juveniles are darker overall. The species has a relatively short tail and broad wings suited for soaring.

The white-backed vulture is found in a variety of habitats across Africa, from the Sahel region to the savannahs of the south. It prefers wooded savannahs where it can find large trees suitable for nesting.

This vulture is widespread across Africa, from Senegal and Gambia in the west, through Ethiopia and Somalia in the east, and down to Mozambique, Zimbabwe, Botswana, Namibia, and South Africa in the south.

White-backed vultures are social creatures, often seen circling the skies in search of carrion. They feed in groups and are typically among the first vultures to arrive at a carcass, asserting dominance over other species. After gorging themselves, they may rest with wings spread to bask in the sun.

19-4-2018 CHOBE NATIONAL PARK, BOTSWANA - WHITE HEADED VULTURE (Trigonoceps occipitalis)

The White-headed Vulture, Trigonoceps occipitalis, presents a striking figure in the African skies. This medium-sized vulture, measuring 72–85 centimeters in length with a wingspan of 207–230 centimeters, is notable for its distinctive plumage. The females, slightly larger than the males, weigh an average of 4.7 kilograms, while the males tip the scales at less than 4 kilograms. The species exhibits reversed sexual dimorphism, a unique trait among its African counterparts.

This vulture is easily recognized by its contrasting black and white plumage. A white crest adorns its head, and the featherless regions of its face are a pale hue. Its beak is tinged pink, and the dark brown upper parts complement the black tail feathers. From below, the white feathers on its lower parts and legs are unmistakable. Each individual can be identified by a unique pattern in their median wing coverts.

The White-headed Vulture is adapted to mixed, dry woodlands at lower altitudes, avoiding human settlements. It thrives in thorny Acacia-dominated landscapes and can be found at elevations up to 4,000 meters in Ethiopia and around 3,000 meters in Kenya.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - 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.

This species is widely distributed across Southern and Eastern Africa and is a vagrant to the southern Arabian Peninsula. It is most abundant in Kenya and can be found from sea level to elevations of 2,000 meters or more.

Lilac-breasted rollers are usually solitary or found in pairs. They are known for their aggressive defense of their nests against raptors and other birds. During the breeding season, males perform acrobatic flights, swooping and diving while emitting harsh cries.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - AFRICAN SACRED IBIS (Threskiornis aethiopicus ssp. aethiopicus)

The African sacred ibis (Threskiornis aethiopicus) is a striking wading bird from the family Threskiornithidae. It is characterized by its all-white plumage, save for the dark plumes on its rump. The adult bird measures approximately 68 cm (27 in) in length, with a wingspan ranging from 112 to 124 cm (44 to 49 in), and weighs between 1.35 to 1.5 kg (3.0 to 3.3 lb). Males are generally slightly larger than females. The species is distinguished by its bald head and neck, thick curved bill, and black legs. In flight, the white wings reveal a contrasting black rear border. The eyes are brown, encircled by a dark red orbital ring.

When identifying the African sacred ibis, look for the combination of its white body, black head, neck, and bill. Juveniles can be recognized by their less pristine white plumage, smaller bill, and some feathering on the neck. The presence of greenish-brown scapulars and more black on the primary coverts also helps to distinguish younger birds.

This ibis favors marshy wetlands and mud flats, both inland and along the coast. It is often found nesting in trees near water and is known to frequent very shallow wetlands, wet pastures with soft soil, cultivation areas, and rubbish dumps.

18-4-2018 CHOBE NAT PARK, BOTSWANA - BLACK HEADED HERON (Ardea melanocephala)

The black-headed heron, Ardea melanocephala, is a stately wading bird from the heron family Ardeidae. It stands at an impressive 85 cm in height, with a wingspan stretching to 150 cm. Its plumage is predominantly grey, with a darker shade above and a paler grey below. The bird is named for its striking black head, which contrasts with its grey body. A powerful dusky bill completes its commanding appearance.

When identifying the black-headed heron, look for its large size, nearly matching that of the grey heron. Its black head and neck, along with the grey body, are key distinguishing features. In flight, observe the slow wingbeats and the retracted neck, a common trait among herons. The white underwing coverts are particularly noticeable when the bird is airborne.

This heron is commonly found in a variety of wetland habitats throughout sub-Saharan Africa and Madagascar. It is comfortable in both shallow water and dry grasslands.

The black-headed heron is widespread across much of sub-Saharan Africa and Madagascar. It is mainly a resident species, though some individuals from West Africa may migrate northward during the rainy season.

The black-headed heron exhibits typical heron behavior, often seen feeding in shallow waters or stalking prey in grasslands. It is known to stand motionless, waiting for prey, or to slowly stalk its victim with stealth and precision.

The vocalizations of the black-headed heron include a distinctive loud croaking, often heard during dusk at heronries.

Breeding typically occurs in the wet season. The black-headed heron nests in colonies, which can be found in trees, reedbeds, or even on cliffs. It constructs a bulky stick nest and lays a clutch of 2 to 4 eggs.

The grey heron is the species most similar in appearance to the black-headed heron, but it can be differentiated by its size and coloration, particularly the grey heron's lack of a black head.

A versatile predator, the black-headed heron feeds on a diet that includes fish, frogs, large insects, small mammals, and birds. It employs both passive and active hunting strategies, either spearing its prey with its sharp bill or stalking it on land.

The IUCN Red List classifies the black-headed heron as Least Concern, indicating that the species does not currently face a significant threat of extinction.

18-4-2018 OKAVANGO DELTA, BOTSWANA - KORI BUSTARD (Ardeotis kori)

The kori bustard (Ardeotis kori) stands as the largest flying bird native to Africa, a member of the bustard family Otididae. Males are particularly hefty, possibly the heaviest living animal capable of flight. The species exhibits sexual dimorphism, with males significantly outweighing females. Their plumage is cryptically colored, blending into their savanna habitats with a mottled pattern of grey, brown, black, and white.

Adult kori bustards are distinguished by their large size, heavy build, and a distinctive black crest on their heads. Their eyes are ringed with white, and they possess a black collar at the base of the hind-neck that extends onto the sides of the breast. The legs are long and yellowish, and the bill is light greenish horn-colored. Juveniles resemble females but are browner with more spotting on the mantle.

Kori bustards favor open grassy areas with sandy soil, short grass, and occasional trees or bushes for cover. They are found in plains, arid plateaus, grasslands, lightly wooded savannas, and semi-deserts, avoiding densely wooded areas.

This species is widespread across southern Africa, with populations extending from Botswana and Namibia to South Africa, Mozambique, and parts of East Africa, including Ethiopia, Kenya, and Tanzania.

Kori bustards are primarily terrestrial, spending much of their time foraging on foot. They exhibit cautious behavior, often fleeing on foot before resorting to flight. They are known for their slow, deliberate walk and can be solitary or found in groups, especially around abundant food sources.

The kori bustard is generally quiet but can produce a deep, booming mating call, a loud growling bark when alarmed, and a snapping bill sound during close encounters.

Breeding is influenced by rainfall, with males engaging in lek mating, displaying at regular sites to attract females. Females lay eggs on the ground in shallow hollows, often near trees or shrubs, and raise the young without male assistance.

The kori bustard can be confused with other large bustards like Denham's and Ludwig's bustards but can be differentiated by its greyer appearance and lack of white upperwing markings in flight.

An opportunistic omnivore, the kori bustard's diet includes insects, small vertebrates, and plant material. They forage by walking slowly and picking at the ground, often following herds of ungulates to catch prey disturbed by their movement.

The kori bustard is classified as Near Threatened due to habitat destruction, hunting, and collisions with power lines. While they can be locally common in protected areas, their populations are generally scarce outside these regions.

19-4-2018 CHOBE NATIONAL PARK, BOTSWANA - BANDED MONGOOSE (Mungos mungo)

The Banded mongoose (Mungos mungo) is a mongoose species native from the Sahel to Southern Africa. While most mongoose species live solitary lives, the Banded mongoose lives in colonies with a complex social structure and forages in groups.

The Banded mongoose is a sturdy mongoose with a large head, small ears, short, muscular limbs, and a long tail, almost as long as the rest of the body. Animals of wetter areas are larger and darker colored than animals in dryer regions. The abdominal part of the body is higher and rounder than the breast area. The rough fur is grayish brown and black, and there are several dark brown to black horizontal bars across the back. The limbs and snout are darker, while the underparts are lighter than the rest of the body. Banded mongooses have long strong claws that allow them to dig in the soil. The nose color of banded mongoose varies from gray-brown to orange-red.

The Banded mongoose lives in sub-Saharan Africa as far north as Somalia and Sudan. Although it does occur in Gambia and Senegal, it is generally considered as rare in West Africa. It occupies a variety of habitats, including brush-land and grassland, but prefers wooded areas. It is not found in drier areas, such as semi-desert and desert habitats.

The Banded mongoose is gregarious and diurnal, living in packs with 10 to 20 members. Packs usually remain together in a group in the same area, but forage individually. They may hunt together to kill larger prey, such as sand snakes. Their home range can measure 0.8 to 4 sq km, and they prefer to use an old termite mound as a den. A pack’s social organization seems to be matriarchal. Packs care for their young and also look after invalids and elderly, for example, by warning them about danger, grooming them, and giving them access to food. These animals are somewhat nomadic and will not inhabit one particular sheltering area or den for long, usually no more than several days or weeks. At a preferred location they may remain a little longer, and often will return to a favorite shelter site or den to re-use it repeatedly.

18-4-2018 CHOBE NAT PARK, BOTSWANA - TAWNY EAGLE (Aquila rapax)

The Tawny Eagle (Aquila rapax) is a large bird of prey, belonging to the family Accipitridae. It is characterized by heavily feathered legs, indicative of its membership in the subfamily Aquilinae, or booted eagles. Exhibiting a polymorphic plumage, the Tawny Eagle's coloration ranges from dark grey-brown to rufous-tawny, with a strong and bold bill, well-proportioned frame, and fierce countenance. This eagle is known for its opportunistic feeding habits, engaging in both active predation and scavenging.

The Tawny Eagle can be identified by its long neck, large bill without a deep gape, and moderately long wings with pronounced "fingers." Its tail is shortish and square-ended, resembling that of a vulture. Adults may have variably colored eyes from yellow to pale brown, with a yellow cere and feet at all ages. The species is polymorphic, with individuals varying in plumage from dark brown to rufous and buffish-yellow.

Tawny Eagles favor open dry habitats such as semideserts, deserts steppes, or savanna plains. They are seldom found in areas completely devoid of trees, as they require perches for hunting and nesting.

The Tawny Eagle has a discontinuous breeding range across much of the African continent and the Indian subcontinent, with rare residency in the southern Middle East.

The Tawny Eagle is largely sedentary and non-migratory, though it may exhibit nomadic tendencies in response to environmental conditions. It spends much of its day perched, taking flight intermittently to hunt or scavenge.

Generally silent, the Tawny Eagle may occasionally vocalize with a harsh, hollow-sounding bark. Males are more vocal, especially during displays of courtship.

Tawny Eagles are resident breeders, laying one to three eggs in a stick nest typically located in the crown of a tree. They often pair for life and are territorial.

The Tawny Eagle can be confused with the Steppe Eagle, but differs in size, gape, and plumage. It also shares its range with various other booted eagles, but can be distinguished by its unique tail shape, bill size, and flight profile.

The Tawny Eagle has a highly variable diet, including live prey such as small to medium-sized mammals, birds, and reptiles, as well as carrion. It is also known for kleptoparasitism, stealing food from other raptors.

The Tawny Eagle is currently listed as Vulnerable on the IUCN Red List. Its population has declined significantly due to habitat loss, persecution, and other anthropogenic factors.

14-11-2018 VILLALONGA RESERVOIR, VALENCIA - WHITE WAGTAIL (Motacilla alba)

The White Wagtail (Motacilla alba) is a small, elegant passerine bird, a member of the family Motacillidae, which includes pipits and longclaws. This slender bird measures between 16.5 to 19 cm in length, with East Asian subspecies reaching up to 21 cm. It is characterized by its long, constantly wagging tail, a behavior that has become synonymous with the genus. Weighing an average of 25 g, the White Wagtail can live up to 12 years in the wild.

Adult White Wagtails exhibit a distinctive plumage with a combination of grey, black, and white. The bird's upper parts are generally grey, with a white face, belly, and breast. Males during the breeding season may show a darker back, and the species is known for its sharp, brisk call and more melodious song during courtship.

The White Wagtail is commonly found in open country, often in close proximity to human habitation and water sources. It shows a preference for bare areas which facilitate the sighting and pursuit of prey. This bird has adapted well to urban environments, utilizing paved areas such as parking lots for foraging.

This species has a vast breeding range across Europe, the Asian Palearctic, parts of North Africa, and has a presence in Alaska. It is a migratory bird, with populations moving to Africa and parts of Asia during the winter. In Great Britain and Ireland, the darker subspecies known as the Pied Wagtail is more prevalent.

14-11-2018 MONTE CORONA, VALENCIA - MEDITERRANEAN KATYDID (Phaneroptera nana)

Phaneroptera nana, common name southern sickle bush-cricket, is a species in the family Tettigoniidae and subfamily Phaneropterinae. It has become an invasive species in California where it may be called the Mediterranean katydid.

This bush cricket is native to mainland Europe, the Near East and North Africa. The Indo-Malayan species Phaneropera subcarinata, described by Bolívar, is morphologically similar to P. nana, and was classified under the P. nana name by Carl Brunner von Wattenwyl. As an invasive species, it has spread to the San Francisco Bay Area and may be widespread in the Los Angeles Basin, with records of its presence in California dating from at least 1952. In addition, it has been recorded in Portland, Oregon since 2015 and South America and hypothesized in the Annals of Carnegie Museum to have spread via shipping.

It mainly inhabits sunny and dry habitats, especially shrubs and low branches of trees.

 

The adult males grow up to 13–15 millimetres (0.51–0.59 in) long, while females can reach 15–18 millimetres (0.59–0.71 in) of length. In both sexes, the basic coloration of the body is light green, with many small black spots. The eyes are bright orange. In some individuals, there may be a brown dorsal stripe where the forewings (tegmina) meet, though the stripe does not extend onto the pronotum.[11] The hindwings are longer than the tegmina, with the tegmina approximately three-fourths of the length of the hindwings.[ In some specimens, the tegmina reach the apex of the posterior femurs. In adult males, the cerci are prominent and curved, while in adult females, the ovipositor is about 5 millimetres (0.20 in) long and has the shape of a sickle.

P. nana and P. falcata are similar in appearance and may be confused for each other in parts of Europe, and elsewhere where the ranges of the two species overlap. These two species may be distinguished by the appearance of the male subgenital plate and the protonum. In P. nana, the male subgenital plate tapers near the end of the body, while in P. falcata, it diverges into two lobes. The protonum of P. nana is narrower than it is tall, while in P. falcata, the protonum is roughly the same width and length, if not longer than tall.

The Mediterranean katydid (Phaneroptera nana) female sings in response to the male, prompting the male to move towards the female. This is unique to the species, because in other species of katydids, it is usually the female moving towards the male in response to hearing their chirps. However, because the females stay static while the males move to locate them, the females are at less risk of encountering threats and predators. However, the males will not decide to interact with a female unless they elicit a response within 60 milliseconds, ensuring that the female is close enough to them.

The females are selective of the males they respond to, and generally they prefer longer chirps. At least two chirps from the males are needed for the female to entertain the males and reply to them. However, more chirps than that from the males do not make the females more likely to duet with the males.

The female Mediterranean katydids lay their eggs in the lamina of plants. The female does this by bending her abdomen and chewing on the lamina to create an opening. The eggs she lays around 3mm in size on average. Those eggs usually hatch in summertime but that can vary. The timing means that P. nana is usually easily encountered through the summer and fall seasons.

14-11-2018 MONTE CORONA, VALENCIA - WAVE MOTH (Idaea filicata)

Idaea filicata is a moth of the family Geometridae. It is found in Southern Europe and the Near East.

The species has a wingspan of 12–21 mm. The adults fly at night from May to September in two to three generations.

Idaea filicata is a moth of the Geometridae family with a wingspan of about 15 mm, ivory white with brown spots on the wings and abdomen. With its wings spread out, the image is that of a white fan with a dark brown circular segment in the centre that reaches halfway and, beyond, a concentric arc of the same brown. The concordance between the front and back wings to form this geometric image is remarkable. On the edge of the wings it has a fringe of white hairs. These white hairs are also found on the back of the thorax, although the specimen in the image has lost them. The legs and antennae are also white.

The image of the adult was obtained in a building, attracted by the light.

The caterpillar is of an indistinct dark colour, between grey and reddish brown, with the segments wrinkled in an apparent second-order segmentation. It appears to feed on numerous herbs when they begin to decay.

In the Iberian Peninsula, Idaea filicata is distributed throughout the Mediterranean lands from Murcia to the north and in the Ebro depression; however, it is absent in the western half.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - SOUTHERN RED BILLED HORNBILL (Tockus rufirostris)

The Southern red-billed hornbill, Tockus rufirostris, is a distinguished member of the Bucerotidae family, gracing the savannas and drier bushlands of southern Africa with its presence. This bird is characterized by its striking red bill and the streaks of blackish plumage that extend from its ear coverts down the side of its neck.

Upon observing this species, one will note the sexual dimorphism where males are generally larger with slightly longer bills. The male's lower mandible may exhibit varying degrees of black pigmentation. Both sexes boast a yellow iris surrounded by pale orbital skin, ranging from pink to greyish hues. The throat is a pristine white, and the wing coverts are adorned with conspicuous spots.

The Southern red-billed hornbill is a native inhabitant of the savannas and dryer bushlands, thriving in these open environments where it can forage and nest.

This hornbill's range extends from Malawi and Zambia to southern Angola, northeastern Namibia, Botswana, Zimbabwe, eastern Eswatini, and northern South Africa, including Transvaal and northern KZN province. It is also found in the upper Zambezi valley of Mozambique, though it is mostly absent from the eastern lowlands.

A notable behavior of the Southern red-billed hornbill is its unique call, an accelerating series of notes that culminates in a crescendo of double notes. Unlike its congeners, this species does not engage in wing-raising displays.

The vocal repertoire of this hornbill includes a distinctive call that starts with a series of "kuk kuk kuk" notes and ends with a flourish of double notes, "kuk-we kuk-we."

The Southern red-billed hornbill can be confused with other red-billed hornbills, but it can be distinguished by its unique combination of yellow iris, pale orbital skin, and the pattern of blackish streaking on the neck.

The conservation status of the Southern red-billed hornbill is not explicitly mentioned, but given its wide distribution, it may not currently be of significant conservation concern. However, like all wildlife, it would benefit from ongoing habitat protection and monitoring.
