4-9-2019 RACO DE OLLA, VALENCIA - COMMON SHELDUCK (FEMALE) (Tadorna tadorna)
The common shelduck (Tadorna tadorna) is a waterfowl species of the shelduck genus, Tadorna. It is widespread and common in the Euro-Siberian region of the Palearctic, mainly breeding in temperate and wintering in subtropical regions; in winter, it can also be found in the Maghreb.
Fossil bones from Dorkovo (Bulgaria) described as Balcanas pliocaenica may actually belong to this species. More likely, they are an extinct species of Tadorna (if not a distinct genus) due to their Early Pliocene age; the present species is not unequivocally attested from the fossil record until some 2–3 million years later (Late Pliocene/Early Pleistocene).
The common shelduck resembles a small short-necked goose in size and shape. It is a striking bird, with a reddish-pink bill, pink feet, a white body with chestnut patches and a black belly, and a dark green head and neck. The wing coverts are white, the primary remiges black, and the secondaries green (only showing in flight) and chestnut. The underwings are almost entirely white. Sexes are similar, but the female is smaller, with some white facial markings, while the male is particularly crisply coloured in the breeding season, his bill bright red and bearing a prominent knob at the forehead.

4-9-2019 CREU DE LONGA, VALENCIA - LITTLE EGRET (Egretta garzetta)
%2020.jpg)
The little egret (Egretta garzetta) is a species of small heron in the family Ardeidae. It is a white bird with a slender black beak, long black legs and, in the western race, yellow feet. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. It breeds colonially, often with other species of water birds, making a platform nest of sticks in a tree, bush or reed bed. A clutch of three to five bluish-green eggs is laid and incubated by both parents for about three weeks. The young fledge at about six weeks of age.
Its breeding distribution is in wetlands in warm temperate to tropical parts of Asia, Africa, Australia, and Europe. A successful colonist, its range has gradually expanded north, with stable and self-sustaining populations now present in the United Kingdom.
In warmer locations, most birds are permanent residents; northern populations, including many European birds, migrate to Africa and southern Asia to over-winter there. The birds may also wander north in late summer after the breeding season, and their tendency to disperse may have assisted in the recent expansion of the bird's range. At one time common in Western Europe, it was hunted extensively in the 19th century to provide plumes for the decoration of hats and became locally extinct in northwestern Europe and scarce in the south. Around 1950, conservation laws were introduced in southern Europe to protect the species and their numbers began to increase. By the beginning of the 21st century the bird was breeding again in France, the Netherlands, Ireland and Britain. Its range is continuing to expand westward, and the species has begun to colonise the New World; it was first seen in Barbados in 1954 and first bred there in 1994. The International Union for Conservation of Nature has assessed the bird's global conservation status as being of "least concern".
4-9-2019 ALBUFERA, VALENCIA - EURASIAN HOOPOE (Upupa epops)
%2020.jpg)
The Eurasian hoopoe (Upupa epops) is the most widespread species of the genus Upupa. It is a distinctive cinnamon coloured bird with black and white wings, a tall erectile crest, a broad white band across a black tail, and a long narrow downcurved bill. Its call is a soft "oop-oop-oop".
The Eurasian hoopoe is native to Europe, Asia and Africa. It is migratory in the northern part of its range. Some ornithologists consider the Madagascar hoopoes as a subspecies. The African hoopoe, subspecies U. e. africana, has sometimes been treated as a separate species.
%2021.jpg)
The Eurasian hoopoe is widespread in Europe, Asia, and North Africa and northern Sub-Saharan Africa. Most European and north Asian birds migrate to the tropics in winter. Those breeding in Europe usually migrate to the Sahel belt of sub-Saharan Africa. The birds predominantly migrate at night. In contrast, the African populations are sedentary all year. The species has been a vagrant in Alaska; U. e. saturata was recorded there in 1975 in the Yukon Delta. Hoopoes have been known to breed north of their European range, and in southern England during warm, dry summers that provide plenty of grasshoppers and similar insects, although as of the early 1980s northern European populations were reported to be in the decline, possibly due to changes in climate. In 2015, a record numbers of hoopoes were recorded in Ireland, with at least 50 birds recorded in the southwest of the country. This was the highest recorded number since 1965 when 65 individuals were sighted.

The Eurasian hoopoe is native to Europe, Asia and Africa. It is migratory in the northern part of its range. Some ornithologists consider the Madagascar hoopoes as a subspecies. The African hoopoe, subspecies U. e. africana, has sometimes been treated as a separate species.
The call is typically a trisyllabic oop-oop-oop, which may give rise to its English and scientific names, although two and four syllables are also common. An alternative explanation of the English and scientific names is that they are derived from the French name for the bird, huppée, which means crested. In the Himalayas, the calls can be confused with that of the Himalayan cuckoo (Cuculus saturatus), although the cuckoo typically produces four notes. Other calls include rasping croaks, when alarmed, and hisses. Females produce a wheezy note during courtship feeding by the male.

6-6-2019 KHWAI CAMP, BOTSWANA - WATTLED CRANE (Grus carunculatus) COURTESY MRS VALERIE FISHER
%20COURTESY%20MRS%20VALERIE%20FISHER%2020.jpg)
The wattled crane (Grus carunculata) is a large, threatened species of crane found in wetlands and grasslands of eastern and southern Africa, ranging from Ethiopia to South Africa. Some authorities consider it the sole member of the genus Bugeranus.
The wattled crane occurs in eleven countries in eastern and southern Africa, including an isolated population in the Ethiopia Highlands. More than half of the world's wattled cranes occur in Zambia, but the single largest concentration occurs in the Okavango Delta of Botswana.
The wattled crane has been spotted in Uganda for the first time in 2011, seen in the Kibimba Rice region in the eastern side of the country. This sighting brings the total number of bird species in Uganda to 1040.
In April 2018, a new population of Wattled Cranes was discovered in Angola.
%20COURTESY%20MRS%20VALERIE%20FISHER%2021.jpg)
Wattled cranes inhabit fairly inaccessible wetlands under most conditions. It requires shallow marsh-like habitats with a good deal of sedge-based vegetation. All cranes are omnivorous. The principal food of the wattled crane is mainly aquatic eating the tubers and rhizomes of submerged sedges and water lilies. It is one of the more herbivorous of extant cranes. The other primary portion of the diet consists of aquatic insects. They will supplement the diet with snails, amphibians and snakes when the opportunity arises. Roughly 90% of foraging done by this species occurs in shallow waters. They typically forage by digging vigorously with their bill into the muddy soil. On occasion, it will eat grain and grass seed as well, but does so much less often than the other three African crane species.
There does seem to be some seasonal movements in this crane species, but they are not well-known. Movements seem to be dictated by local water conditions rather than by seasonal temperature variations. During local floods, the number of wattled cranes can increase from almost none to as much as 3,000 individuals. These movements, in pursuit of ideal feeding conditions, seem more opportunistic movement rather than a fixed migration pattern. On the other hand, there has been observed a migration movement from the high to the low plateaus in Mozambique for the species.

1-9-2019 MONTE CORONA, VALENCIA - MEDITERRANEAN MANTIS (FEMALE) (Iris oratoria)
Reproduction: Lays eggs in a foam-like ootheca that hardens for protection. Parthenogenesis (reproduction without males) can occur if males are scarce.
Behavior: A highly efficient ambush predator that consumes small insects. Sexual cannibalism can occur.
Habitat and Range Native Range: The Mediterranean region of Europe.Introduced Range: It has also been introduced to the Middle East, Western Asia, and the United States, where it is spreading. As an Invasive Species The Mediterranean Mantis is considered an invasive species in parts of the United States, having been introduced to southern California in the 1930s.It has adapted well to the climate there and seems to be spreading further.
1-9-2019 PEGO MARJAL, ALICANTE - NOMAD DRAGONFLY (MALE AND FEMALE) (Sympetrum fonscolombii)
The red-veined darter or nomad (Sympetrum fonscolombii) is a dragonfly of the genus Sympetrum.
Sympetrum fonscolombii was named under the protonym Libellula fonscolombii by the Belgian entomologist Edmond de Sélys Longchamps, in 1840, in honor of the French entomologist Étienne of Fonscolombe (hence the species name). Its name is sometimes spelt fonscolombei instead of fonscolombii but Askew (2004) gives the latter as the correct spelling.
Sympetrum fonscolombii can reach a body length of 38–40 millimetres (1.5–1.6 in). This species is similar to other Sympetrum species but a good view with binoculars should give a positive identification, especially with a male.
Males have a red abdomen, redder than many other Sympetrum species. The frons and the thorax are red-brown. The eyes are brown above and blue/grey below. The wings have red veins and the wing bases of the hind-wings are yellow. The pterostigma is pale yellow with a border of black veins.
Female are similar but the abdomen is ochre yellow, not red, with two black lines along each side. The wings have yellow veins at the costa, leading edge and base, not red veins as found in the males. The legs of both sexes are mostly black with some yellow.
Immature males are like females but often with more red and a single line along each side of the abdomen.
Male S. fonscolombii can be mistaken for Crocothemis erythraea as both are very red dragonflies with yellow bases to the wings, red veins and pale pterostigma. However C. erythraea has no black on the legs, a broader body and no black on the head. Also C. erythraea females do not oviposit in tandem. The gestalt image of these two species is different and with some experience are easy to tell apart.
1-9-2019 PEGO MARJAL, ALICANTE - SCARLET DARTER DRAGONFLY (MALE) (Crocothemis erythraea)
%20(Crocothemis%20erythraea)%2020.jpg)
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.
%20(Crocothemis%20erythraea)%2021.jpg)
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.
1-9-2019 PEGO MARJAL, ALICANTE - PAINTED LADY BUTTERFLY (Vanessa cardui)
Painted Lady butterflies are known for their wide distribution, impressive long-distance migrations, and distinct orange, black, and white wing patterns. They are one of the most widespread butterfly species globally, found on every continent except Australia and Antarctica. Their lifespan is short, lasting only a few weeks, during which females lay about 500 eggs.
Migration and distribution
Global presence: They are found worldwide, with the exception of Australia and Antarctica.
Migratory journey: They are known for their long-distance migrations, which can involve traveling thousands of miles.
Non-stop travel: No single individual butterfly completes the entire round trip; multiple generations are involved in the journey across continents.
1-9-2019 PEGO MARJAL, ALICANTE - HOUSE SPARROW (FEMALE) (Passer domesticus)
%20(Passer%20domesticus)%2020.jpg)
These noisy and sociable birds are found around the world, thanks to their cheerful ability to make the most of humanity's rubbish and wastefulness. But monitoring suggests a severe decline in the UK House Sparrow population, recently estimated as dropping by 71% between 1977 and 2008 with large falls in both rural and urban populations. Their numbers are still dropping in England, Breeding Bird Survey data indicates recent population increases in Scotland, Wales and Northern Ireland.
1-9-2019 MONTE CORONA, VALENCIA - BLUE ROCK THRUSH (FEMALE) (Monticola solitarius)
%20(Monticola%20solitarius)%2020.jpg)
The blue rock thrush (Monticola solitarius) is a species of chat. This thrush-like Old World flycatcher was formerly placed in the family Turdidae. It breeds in southern Europe, northwest Africa, and from Central Asia to northern China and Malaysia. The blue rock thrush is the official national bird of Malta (the word for it in Maltese being Merill) and was shown on the Lm 1 coins that were part of the country's former currency.
The blue rock thrush is a starling-sized bird, 21–23 cm (8.3–9.1 in) in length with a long slim bill. The breeding male of the nominate subspecies is unmistakable, with all blue-grey plumage apart from its darker wings.[6] Females and immatures are much less striking, with dark brown upperparts, and paler brown scaly underparts. The male of the subspecies M. s. philippensis has rufous-chestnut plumage from the mid-breast down to the undertail. Both sexes lack the reddish outer tail feathers of rock thrush.
The male blue rock thrush sings a clear, melodious call that is similar to, but louder than, the call of the rock thrush.
%20(Monticola%20solitarius)%2021.jpg)
The European, north African and southeast Asian birds are mainly resident, apart from altitudinal movements. Other Asian populations are more migratory, wintering in sub-Saharan Africa, India and southeast Asia. This bird is a very uncommon visitor to northern and western Europe. There is some overlap in breeding and wintering ranges with the common rock thrush (Monticola saxatilis); Palearctic and southwestern Asia for breeding and northern Africa for wintering. It is known to have been spotted in North America twice: once in British Columbia in 1997 and once in Oregon and the Farallon Islands in 2024. It is unclear whether the Oregon and Farallon Islands spottings were the same bird.
The blue rock thrush breeds in open mountainous areas. It nests in rock cavities and walls, and usually lays 3–5 eggs. An omnivore, the blue rock thrush eats a wide variety of insects and small reptiles in addition to berries and seeds.

29-8-2019 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.
Physical characteristics Size: Adults grow to about \(15-20\) cm long, with the tail making up two-thirds of the total length.Body shape: They are slender with a long tail, a narrow head, and long, thin toes.Color: Dorsal colors are typically grey-brown with varied patterns. Females tend to have more prominent longitudinal stripes, while males are often smaller. Some individuals also have ventral color variations, including yellow, orange/red, and white morphs.
Habitat and behavior Habitat: The species is adaptable and can be found in various environments, including rocky areas, shrubby vegetation, and even human settlements.Distribution: Its range extends from the Rhône Valley in France to the Sierra Nevada in Spain.
Activity: They are diurnal and active, often seen basking, foraging, and hiding in vegetation.Diet: They feed on small invertebrates and sometimes fruit.Reproduction: As an oviparous (egg-laying) species, females lay an average of 2.80 eggs per clutch in continental populations.
28-8-2019 EL SALER, VALENCIA - GREY HERON (Ardea cinerea)
%2019.jpg)
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.
%2020.jpg)
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.
%2021.jpg)
The primary call of the Grey Heron is a loud croaking "fraaank." At breeding colonies, a variety of guttural and raucous noises can be heard, including greeting calls between mates and alarm calls when predators are nearby.
Breeding takes place in colonies, or heronries, typically in high trees near water. Nests are reused and added to each year. The breeding season sees a clutch of three to five bluish-green eggs laid, which both parents incubate. Chicks fledge at 7-8 weeks old.
The Grey Heron can be confused with the larger North American Great Blue Heron or the South American Cocoi Heron. However, it can be distinguished by its size and the coloration of its flanks and thighs.
Grey Herons are apex predators within their ecosystem, feeding on a variety of aquatic creatures such as fish, amphibians, crustaceans, and insects. They have also been known to consume small mammals and juvenile birds.
The Grey Heron is classified as Least Concern by the IUCN, indicating a stable and widespread population.
