15-4-2018 CHOBE NATIONAL PARK, SOUTH AFRICA - BLACK BACKED JACKAL (Canis mesomelas)
The black-backed jackal (Lupulella mesomelas), also called the silver-backed jackal, is a medium-sized canine native to eastern and southern Africa. These regions are separated by roughly 900 kilometers.
One region includes the southernmost tip of the continent, including South Africa, Namibia, Botswana, and Zimbabwe. The other area is along the eastern coastline, including Kenya, Somalia, Djibouti, Eritrea, and Ethiopia. It is listed by the IUCN as least concern, due to its widespread range and adaptability, although it is still persecuted as a livestock predator and rabies vector.
The species generally shows a preference for open areas with little dense vegetation, though it occupies a wide range of habitats, from arid coastal deserts to areas with more than 2000 mm of rainfall. It also occurs in farmlands, savannas, open savanna mosaics, and alpine areas.
Compared to members of the genus Canis, the black-backed jackal is a very ancient species, and has changed little since the Pleistocene, being the most basal wolf-like canine, alongside the closely related side-striped jackal. It is a fox-like animal with a reddish brown to tan coat and a black saddle that extends from the shoulders to the base of the tail. It is a monogamous animal, whose young may remain with the family to help raise new generations of pups. The black-backed jackal has a wide array of food sources, feeding on small to medium-sized animals, as well as plant matter and human refuse.

24-8-2018 RIO SERPIS, GANDIA - FERAL PIGEON (Columba livia var. domestica)
The domestic pigeon (Columba livia domestica or Columba livia forma domestica) is a pigeon subspecies that was derived from the rock dove or rock pigeon. The rock pigeon is the world's oldest domesticated bird. Mesopotamian cuneiform tablets mention the domestication of pigeons more than 5,000 years ago, as do Egyptian hieroglyphics.
Pigeons have held historical importance to humans as food, pets, holy animals, and messengers. Due to their homing ability, pigeons have been used to deliver messages, including during the world wars. Despite this, city pigeons, which are feral birds, are generally seen as pests, mainly due to their droppings. Feral pigeons are considered invasive in many parts of the world, though they have a positive impact on wild bird populations, serving as an important prey species for birds of prey.

20-4-2018 OKAVANGO DELTA, BOTSWANA - STRIPED KINGFISHER (Halcyon chelicuti) COURTESY OF MRS VALERIE FISHER
The Striped Kingfisher, known scientifically as Halcyon chelicuti, is a member of the tree kingfisher subfamily. It is a small, robust bird, with a general length ranging from 16 to 18 cm. The upper parts of the adult are predominantly greyish brown, while the lower back, secondary flight feathers, and tail boast a striking metallic blue, which is particularly visible in flight. The underparts are off-white, with varying degrees of buff and brown streaking across the subspecies.
When perched, the Striped Kingfisher may appear rather inconspicuous, but its flight reveals a white patch at the base of the primary flight feathers and a black border along the wing linings. Males can be identified by a black bar at the base of the primaries. The head is streaked dark brown, with a buffy grey or brownish background depending on the sex. A black line runs through the eyes and around the back of the neck, sitting above a white collar. The bill is blackish above and reddish-orange below, with the lower mandible being dull red in juveniles.
The Striped Kingfisher favors woodlands, thorn scrub, dry bush, and open savannas, but it tends to avoid densely forested areas, intensive farmlands, and extreme deserts.
This species is found throughout Sub-Saharan Africa, with two subspecies: H. c. chelicuti occupying most of the range, and H. c. eremogiton residing in the northern desert regions from central Mali to eastern Sudan.
Highly territorial, the Striped Kingfisher defends an area that may encompass up to three hectares and contain around 100 tall trees. It is known to chase away intruders, including other kingfishers, shrikes, doves, and rollers. The bird surveys its territory from a treetop, singing from before dawn until after midday.
The call of the Striped Kingfisher is a high-pitched, piercing "cheer-cherrrrrr" or a far-carrying "KEW, kerrrrrrrrr," with the latter featuring a descending trill. This call is often part of a dusk display involving wing-opening.

22-8-2018 EL SALER, VALENCIA - DROMEDARY CAMEL (Camelus dromedarius)
Camels have a slow growth rate and reach sexual maturity slower than sheep or goat. The age of sexual maturity varies geographically and depends on the individual, as does the reproductive period. Both sexes might mature by three to five years of age, though successful breeding could take longer. Camels are described as atypical seasonal breeders; they exhibit spermatogenesis throughout the whole year with a reduction in spermatogenesis during the nonbreeding season compared to that in the breeding season (Zayed et al., 1995). The breeding season in Egypt is during spring; the spring months. Mating occurs once a year, and peaks in the rainy season. The mating season lasts three to five months, but may last a year for older animals.
Its range included hot, arid regions of northern Africa, Ethiopia, the Near East, and western and central Asia. The dromedary typically thrives in areas with a long dry season and a short wet season. They are sensitive to cold and humidity, though some breeds can thrive in humid conditions.
22-8-2018 ALBUFERA, VALENCIA - LITTLE EGRET (Egretta garzetta)
With its yellow feet, which are used to flush prey when feeding in shallow water, the Little Egret is a distinctive member of the heron family. Little Egrets first bred in Britain in 1996 and since then have successfully colonised much of southern Britain and Ireland.
Little Egrets first bred in Britain in 1996 and since then have successfully colonised much of southern Britain and Ireland. Most of the breeding colonies have been established within existing Grey Heron colonies, the two species nesting alongside one another.
The winter distribution is also currently restricted to the southern half of Britain & Ireland, despite the fact that young birds are known to move some distance from their natal site.
The little egret, a captivating member of the heron family, Ardeidae, has long enchanted observers with its elegant appearance. Boasting a slender body, pristine white plumage, and long black legs, this bird is the epitome of grace and poise. Found throughout Europe, Africa, Asia, and even as far as Australia, the little egret has a wide distribution, allowing it to grace numerous landscapes and ecosystems with its beauty.
While the little egret itself may not feature prominently in folklore or myths, it is worth noting that its close relatives, the herons and egrets, do have cultural significance in various parts of the world. For instance, in Japanese folklore, the white heron is a revered figure that is often associated with purity, elegance, and transformation. These transformed herons, known as “sagi musume,” are believed to have the ability to take on the form of beautiful women, and are depicted in various forms of traditional Japanese art and theater. This cultural association highlights the admiration and respect for the little egret’s larger family of birds and the captivating charm they possess.
22-8-2018 ALBUFERA, VALENCIA - GREY HERON (Ardea cinerea)
Grey Herons are unmistakeable – tall, with long legs, a long beak and grey, black and white feathering. They can stand with their neck stretched out, looking for food, or hunched down with their neck bent over their chest.
The Grey Heron is a distinctive species with grey, black, and white plumage. It is often seen along rivers or lake margins, or standing in flooded fields.
In flight their large size, impressive wingspan, long legs, and folded neck give them an unmistakable silhouette. Largely silent away from colonies, flight is sometimes accompanied by a harsh ‘kraank’ call.
Grey Herons gather to nest in treetop sites called heronries, some of which have been occupied for many decades. These have been monitored in the UK since 1928 through the Heronries Census. Overall the UK's breeding population has increased, with numbers peaking in the early 2000, but with some more recent declines.
