25-7-2018 MONTE CORONA, VALENCIA - CATALONIA WALL LIZARD (Podarcis liolepis)
Podarcis liolepis, the Columbretes wall lizard or Catalan wall lizard, is very similar to the other lizards in the genus Podarcis. This species was formerly described as a subspecies of the Iberian wall lizard, but has now been elevated to species status. These are slender lizards with long tails, narrow tapered heads and long thin toes, and stout legs. Colours are variable, although generally grey-brown. Often very subtle spots and stripes along the back and flanks can be seen and these can be more distinguished in the female. The underside is a much lighter cream or beige with sometimes a reddish tint. Adults grow 15–20 cm in length from the nose to tip of the tail. Body length can be a little as one third of the total body length, the tail making up the other two thirds.
Lifespan around 4–5 years. Sexual maturity is reached in their second year. Breeding takes place in spring after they wake from winter hibernation. 1-5 eggs are laid, each around 5x9mm, in cracks in rocks or under stones. During development the eggs swell and after 8 weeks when ready to hatch they can be 8x15mm in size. They hatch out around early July.
They are found in the north-east of the Iberian peninsula, including southern France in parts of the Pyrenees. They are not found above 3400m elevation.

25-7-2018 CATARROJA, VALENCIA - GREY HERON (Ardea cinerea)
The Grey Heron (Ardea cinerea) is a statuesque wading bird belonging to the family Ardeidae. It is a familiar sight in both rural and urban settings, often seen standing stoically along the water's edge. An adult Grey Heron is a large bird, reaching up to 100 cm in height, with a wingspan between 155 to 195 cm. It weighs between 1 to 2 kg. The plumage is predominantly ashy-grey above, with a greyish-white underbelly and some black on the flanks. A striking feature is the white head and neck adorned with a broad black stripe that extends from the eye to the black crest. The beak is pinkish-yellow, long, and sharply pointed, while the legs are a brown hue.
When identifying the Grey Heron, look for the white head with the black supercilium and crest, the long grey neck, and the ashy-grey wings and back. The underparts are lighter, and the legs are long and brown. Juveniles can be distinguished by their duller grey neck and smaller crest. The beak is a useful indicator of age, being brighter in breeding adults.
Grey Herons are highly adaptable and can be found in a variety of watery habitats including lakes, rivers, ponds, marshes, and coastal environments. They require shallow waters for foraging or areas with shelving margins where they can wade.
Native to temperate Europe and Asia, as well as parts of Africa, the Grey Heron has a broad range. Northern populations may migrate southwards in autumn, while others remain resident year-round. Vagrant sightings have occurred in the Caribbean, Bermuda, and parts of North America.
The Grey Heron exhibits a slow, deliberate flight with its neck retracted in an S-shape. It is known for its solitary foraging habits, often standing motionless or stalking prey through shallow waters. It is also a communal rooster, often found in trees or cliffs at night.
25-7-2018 CATARROJA, VALENCIA - BARN SWALLOW (Hirundo rustica)
The barn swallow (Hirundo rustica) is a migratory passerine bird, recognized as the most widespread species of swallow in the world. It is a distinctive bird with blue upperparts and a long, deeply forked tail, known for its graceful flight and agile maneuvers. The adult male of the nominate subspecies is 17–19 cm in length, including elongated outer tail feathers, and has a wingspan of 32–34.5 cm. It is adorned with a rufous forehead, chin, and throat, which are set apart from the off-white underparts by a broad dark blue breast band. The outer tail feathers are elongated, contributing to the iconic "swallow tail."
The barn swallow can be identified by its steel blue upperparts, a rufous face, and a dark blue breast band that separates the rufous from the off-white underparts. The deeply forked tail is a key characteristic, with a line of white spots across the upper tail's outer end. Females resemble males but have shorter tail streamers and less glossy blue coloring. Juveniles are browner with paler rufous faces and whiter underparts, lacking the adult's long tail streamers.
The barn swallow favors open country with low vegetation, such as pastures, meadows, and farmland, often near water. It avoids heavily wooded or steep areas and densely built-up locations. The species typically nests in man-made structures like barns and stables, or under bridges and wharves.
This bird has a vast global range, breeding across the Northern Hemisphere and wintering in much of the Southern Hemisphere. Its distribution spans Europe, Asia, Africa, and the Americas.
Barn swallows are semi-colonial and may settle in groups. They exhibit site fidelity, often returning to the same location annually for breeding. The species is known for its aerial insectivory, catching insects in flight with remarkable agility.
The barn swallow communicates with a variety of calls, including a "witt or witt-witt" and a loud "splee-plink" when excited or deterring intruders. Alarm calls include a sharp "siflitt" for terrestrial predators and a "flitt-flitt" for avian predators. The male's song, used for territory defense and mate attraction, consists of a twittering warble followed by a series of musical notes.
Barn swallows are monogamous and often mate for life, with the male arriving first at the breeding grounds to select a nest site. They build cup-shaped mud nests lined with soft materials, frequently in colonies where each pair defends a territory. The female typically lays two to seven spotted white eggs, with the clutch size varying by latitude.
The barn swallow can be confused with other Hirundo species and the welcome swallow in overlapping ranges. However, its red face and blue breast band distinguish it from African species, and it differs from the welcome swallow by its deeply forked tail and white tail spots.
The diet consists mainly of flying insects, which the barn swallow captures in open areas or follows animals and humans to catch disturbed prey. It may also pick insects from water surfaces, walls, and plants. The species drinks and bathes by skimming over water bodies.
The barn swallow is classified as Least Concern by the IUCN, with an extensive range and large global population. While not endangered, local declines may occur due to specific threats, such as habitat loss or pesticide use. However, the species has benefited from human expansion and the availability of nesting sites.

8-4-2018 THORNYBUSH GAME LODGE, SOUTH AFRICA - PALE EMERALD SPOTTED WOOD DOVE (Turtur chalcospilos)
%2020.jpg)
The emerald-spotted wood dove or emerald-spotted dove (Turtur chalcospilos) is a bird of the family Columbidae, resident across eastern and southern Africa. It is a species of open drier deciduous woodland and second growth. It is absent from evergreen rainforests and semidesert areas.
The emerald-spotted wood dove is a small plump pigeon, typically 20 cm in length. Its back, hindneck, wings, and tail are pale grey-brown, and the folded wings have green metallic patches. There are blackish bands on the lower back and tail. The forehead, crown, and nape are bluish-grey, fading to pinkish-grey on the throat. The underparts are mauve-pink, becoming whiter on the belly.
The bill of this dove is blackish with a red base. The sexes are similar, but the female may be slightly duller than the male. The immature has duller green spots and buff fringes to the feathers. When flying, the black-billed wood dove is told from this species by its bright chestnut underwings.
The call is in three parts: two soft long coos, followed by a series of slow descending coos lasting 10 seconds, and concluding with 4 seconds of rapid coos, which decrease in volume.
This species shows some geographical variation in plumage, but differences are clinal, and emerald-spotted wood dove is now considered to be monotypic.
The emerald-spotted wood dove builds a flimsy stick nest in a tree or shrub, and lays two cream-coloured eggs. Both sexes incubate for 13–17 days to hatching, and feed the squabs for 13–17 days to fledging. Many young birds are taken by mongooses and shrikes.
The emerald-spotted wood dove is not gregarious, but flocks may form at waterholes. This species usually forages on the ground for grass and other small seeds.
7-4-2018 THORNYBUSH LODGE, SOUTH AFRICA - AFRICAN LION (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.
5-4-2018 THORNYBUSH LODGE, SOUTH AFRICA - SOUTHERN WHITE RHINOCEROS (Ceratotherium simum ssp simum)
The southern white rhinoceros or southern white rhino (Ceratotherium simum simum) is one of the two subspecies of the white rhinoceros (the other being the much rarer northern white rhinoceros). It is the most common and widespread subspecies of rhinoceros.
The southern white rhinoceros is the nominate subspecies; it was given the scientific name Ceratotherium simum simum by the English explorer William John Burchell in the 1810s. The subspecies is also known as Burchell's rhinoceros (Ceratotherium simum burchellii) after Burchell and Oswell's rhinoceros (Ceratotherium simum oswellii) after William Cotton Oswell, respectively. However, these are considered synonyms of its original scientific name.
Ceratotherium simum kiaboaba (or Rhinoceros kiaboaba), also known as straight-horned rhinoceros, was proposed as a different subspecies (or species) found near Lake Ngami and north of the Kalahari Desert. However, it is now considered part of the southern white rhinoceros and ranges throughout southern Africa.
Lifespan is up to 50 years in the wild.
8-4-2018 THORNYBUSH LODGE, SOUTH AFRICA - SPOTTED HYENA (Crocuta crocuta)
A highly misunderstood animal, the Spotted hyena (Crocuta crocuta) has the reputation of being cowardly and sly, but it is actually a fascinating and intelligent creature with a very interesting social system. It looks like a dog but is closer related to cats, civets, and genets. It is also called the laughing hyena. It is a strong and capable hunter and the largest member of the hyena family. Females and males look exactly the same except that females are a little larger.
The spotted hyena has a strong and well-developed neck and forequarters, but relatively underdeveloped hindquarters. The rump is rounded rather than angular, which prevents attackers coming from behind from getting a firm grip on it. The head is wide and flat with a blunt muzzle and broad rhinarium. In contrast to the striped hyena, the ears of the spotted hyena are rounded rather than pointed. Each foot has four digits, which are webbed and armed with short, stout, and blunt claws. The paw-pads are broad and very flat, with the whole undersurface of the foot around them being naked. The tail is relatively short, being 300-350 mm (12-14 in) long, and resembles a pompom in appearance. Unusually among hyaenids, and mammals in general, the female Spotted hyena is considerably larger than the male. Both sexes have a pair of anal glands that produce a white, creamy secretion that is pasted onto grass stalks by everting the rectum. The odor of this secretion is very strong, smelling of boiling cheap soap or burning, and can be detected by humans several meters downwind.

21-4-2018 OKAVANGO DELTA, BOTSWANA - AFRICAN LEOPARD (FEMALE) (Panthera pardus pardus)
The African leopard (Panthera pardus pardus) is the nominate subspecies of the leopard, native to many countries in Africa. It is widely distributed in most of sub-Saharan Africa, but the historical range has been fragmented in the course of habitat conversion. Leopards have also been recorded in North Africa as well.
The African leopard exhibits great variation in coat color, depending on location and habitat. Coat color varies from pale yellow to deep gold or tawny, and sometimes black, and is patterned with black rosettes while the head, lower limbs, and belly are spotted with solid black. Male leopards are typically larger and heavier than females.
23-7-2018 VILLALONGA RESERVOIR, VALENCIA - SCARLET DARTER DRAGONFLY (Crocothemis erythraea)
The scarlet dragonfly (Crocothemis erythraea) is a species of dragonfly in the family Libellulidae. Its common names include broad scarlet, common scarlet-darter, and scarlet darter.
The scarlet dragonfly is a common species in southern Europe and throughout Africa. It also occurs across western Asia as far as southern China. It is a very rare vagrant in Britain. Its first record in the country was at Hayle Kimbro Pool, The Lizard, Cornwall, on 7 August 1995. Since then there have been a few further records at scattered locations throughout Britain.
A wide range of both running and standing waters, except those that are shaded. Adults may be found some distance from water in habitats ranging from desert to open woodland; absent from dense forest.
Crocothemis erythraea can reach a length of 33–44 millimetres (1.3–1.7 in). These dragonflies haves a flattened and rather broad abdomen. The adult male scarlet dragonfly has a bright scarlet red, widened abdomen, with small amber patches at the bases of the hindwings. Also the veins on the leading edges of the wings are red. Females and immatures are yellow-brown and have a conspicuous pale stripe along the top of the thorax.
23-7-2018 VILLALONGA RESERVOIR, VALENCIA - COPPER DEMOISELLE DAMSELFLY (FEMALE) (Calopteryx haemorrhoidalis)
Calopteryx haemorrhoidalis is a species of damselfly in the family Calopterygidae known by the common names copper demoiselle and Mediterranean demoiselle.
The Copper Demoiselle is a species of damselfly which is found in southern Europe. It is often found along streams and rivers, which are clear and rich in oxygen. The abdomen of the male shows a distinctive pink rear.
The wingspan is 60–70 mm. Adults fly from April to September.
Calopteryx haemorrhoidalis is a species of damselfly in the family Calopterygidae known by the common names copper demoiselle and Mediterranean demoiselle.
This species is native to the western Mediterranean Basin in Europe (Iberia, southern France, Italy, Monaco) and North Africa (Algeria, Morocco, Tunisia). It is common in much of its range.
It lives along rivers and streams, but also in sunny larger waters. Though it may be affected by habitat changes such as water pollution.

1-4-2018 EDEN PLETTENBERG BAY, SOUTH AFRICA - SPOTTED THICK NEE (Burhinus capensis)
The Spotted Thick-knee, also known as the Spotted Dikkop or Cape Thick-knee, is a bird of notable stature, reaching up to 45.5 cm in height. It is adorned with brown-and-white speckled plumage that blends seamlessly into the grasslands and savannas it calls home. The bird's head is large and round, crowned with a prominent yellow eye, while its short, stout beak is well-suited to its diet. In flight or when displaying its characteristic wings-raised stance, it reveals a striking contrast in its plumage. Its legs are long and yellow, and the tibiotarsal joint is notably expanded, a feature that has given rise to its common name.
To identify the Spotted Thick-knee, look for its long yellow legs and the distinctive thickening at the knee joint. Its camouflage plumage can make it challenging to spot, but the bird's large, round head and prominent yellow eyes are key distinguishing features. When it takes to the air or assumes its unique pose with wings aloft, the contrasting patterns of its plumage become quite apparent.
This species thrives in the grasslands and savannas, where its mottled plumage provides excellent camouflage against the backdrop of these ecosystems.
The Spotted Thick-knee is native to sub-Saharan Africa, with a range that spans from Senegal, Mali, and Mauritania in the west, across to Ethiopia, Kenya, Tanzania, and down to South Africa in the east and south. It is also found in south Yemen.
