20-9-2018 ALARCOS, LA MANCHA - SQUIRTING CUCUMBER (Ecballium elaterium)
Ecballium is a genus of flowering plants in the family Cucurbitaceae containing a single species, Ecballium elaterium, also called the squirting cucumber, as well as the noli me tangere[citation needed] and its English translation touch-me-not[citation needed]. Its unusual common name derives from the ripe fruit squirting a stream of mucilaginous liquid containing its seeds as a means of seed dispersal, an example of rapid plant movement.
E. elaterium is native to Europe, northern Africa, and temperate areas of Asia, and is considered an invasive species. It is grown as an ornamental plant elsewhere, and in some places it has naturalized.
The tissue in the fruit of the Ecballium elaterium that surrounds the seeds is made of large, thin-walled cells facilitating the propulsive release of seeds by "squirting". Pressure to expel the seeds is created by the increased concentration of a glucoside called elaterinidin in the sap of the fruit tissue's cells, leading to a turgor pressure of up to 27 atms. The seeds are projected as far as 7–8 m (23–26 ft). The pressure builds up until its force detaches the fruit from the stalk. At the same time, the pericarp contracts and the fruit and seeds are ejected through the hole produced by detachment. The pressure-building method may depend on the phloem sieve tubes, indicating that the squirting mechanism can be decreased in water stressed conditions.
20-9-2018 ALARCOS, LA MANCHA - EUROPEAN HELIOTROPE (Heliotropium europaeum)
Heliotropium europaeum is a species of heliotrope known by the common names European heliotrope and European turn-sole. It is native to Europe, Asia, and North Africa, but it is widely naturalized elsewhere, such as in Australia and North America. It grows as a roadside weed in some places. This is an annual herb growing from a taproot and reaching maximum heights near 40 centimeters.
The stem and oval-shaped leaves are covered in soft hairs. The inflorescences are coiled spikes of white flowers with fuzzy or bristly sepals. Each flower is just a few millimeters wide. The fruit is a bumpy nutlet.
Toxicity
Heliotropium europaeum contains pyrrolizidine alkaloids and is poisonous.

19-9-2018 TABLAS DE DAIMIEL, LA MANCHA - BLACK TAILED GODWIT (Limosa limosa)
The black-tailed godwit favors a range of wetland habitats for breeding, including fens, lake edges, damp meadows, moorlands, and bogs. It is also known to adapt to human-altered landscapes such as wet grasslands and pastures.
This species has a broad breeding range that spans from Iceland across Europe to central Asia. During the northern hemisphere winter, it migrates to diverse regions including the Indian subcontinent, Australia, New Zealand, western Europe, and west Africa.
The black-tailed godwit is a sociable bird, often seen migrating in flocks. It exhibits a strong fidelity to its breeding grounds, where pairs reunite each season with remarkable punctuality. If a mate is delayed, 'divorce' may ensue.
The most frequently heard call of the black-tailed godwit is a loud and insistent "weeka weeka weeka."

18-9-2018 TABLAS DE DAIMIEL, LA MANCHA - EURASIAN LINNET (MALE) (Linaria cannabina)
%20(Linaria%20cannabina)%2020-gigapixel-scale-1_5x.jpg){kind=tracking}
The common linnet (Linaria cannabina) is a small passerine bird of the finch family, Fringillidae. It derives its common name and the scientific name, Linaria, from its fondness for hemp seeds and flax seeds—flax being the English name of the plant from which linen is made.
The common linnet is a slim bird with a long tail. The upper parts are brown, the throat is sullied white and the bill is grey. The summer male has a grey nape, red head-patch and red breast. Females and young birds lack the red and have white underparts, the breast streaked buff.
The common linnet breeds in Europe, the western Palearctic and North Africa. It is partially resident, but many eastern and northern birds migrate farther south in the breeding range or move to the coasts. They are sometimes found several hundred miles off-shore. It has been introduced to the Dominican Republic.
17-9-2018 MONTE CORONA, VALENCIA - MOORISH GECKO (Tarentola mauritanica)
Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas (in Montevideo, Buenos Aires and California). A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter. A robust species, up to 15 centimetres (5.9 in) long, its tubercules are enlarged and give the species a spiny armoured appearance.
The species was first described by Carl Linnaeus in 1758. It is also known as moorish gecko, crocodile gecko, European common gecko, and, regionally, as osga (in Portuguese), salamanquesa (in Spanish) and dragó (in Catalan).

15-4-2018 CHOBE RIVER, NAMIBIA - WHITE FRONTED BEE-EATER (Merops bullockoides)
%2020.jpg)
The White-fronted Bee-eater, known scientifically as Merops bullockoides, is a vibrant and slender bird adorned with a striking black mask and a white forehead. Its square tail and bright red throat patch are distinctive features. Measuring at 23 cm in length, the bird's upperparts are a lush green, while its underparts boast a warm cinnamon hue. Its call is a resonant, deep squeak that carries through the air.
To identify the White-fronted Bee-eater, look for its unique combination of colors: a black mask, white forehead, green upperparts, and cinnamon underparts. The square tail and bright red throat patch are also key identifiers. Listen for its deep squeaking call as a helpful auditory clue.
This species thrives in the open savannahs of sub-equatorial Africa, often found near gullies where their insect prey, particularly bees, are abundant.
The White-fronted Bee-eater is widely distributed across the savannah regions of sub-equatorial Africa, where it is a common sight in its preferred habitat.
The White-fronted Bee-eater exhibits a complex social structure, nesting in colonies that can average around 200 individuals. These colonies are not just for breeding but also serve as a communal space for roosting and socializing. The birds demonstrate cooperative breeding, with non-breeding individuals acting as helpers to their kin, significantly increasing the success rate of raising young.
10-11-2016 MANDALAY, MYANMAR - FRECKLE BREASTED WOODPECKER (Dendrocopos analis)
%2020.jpg)
The freckle-breasted woodpecker (Dendrocopos analis ) is a species of bird in the family Picidae.It is found in Indonesia, Laos, Myanmar, Thailand, Cambodia, and Vietnam.

13-9-2018 MONTE CORONA, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)
House sparrows are distinguished by their compact shape and powerful beak. A house sparrow’s back and wings are striped brown and black, and its abdomen, crown and cheeks are grey. It may be tricky to distinguish a house sparrow from a tree sparrow, however, they do differ: the tree sparrow has chocolate-brown areas and small, black stains on its cheeks.
House sparrows are some of the most well-known songbirds in the UK
Female house sparrows are not as loud as their male counterparts. While the male has brown areas near his eyes that frame his cheeks, the female’s face is almost completely grey. In addition, the male’s breast and throat are covered with what look like black stains–stains that are conspicuously missing from the female.
Note: The area of black on the male’s breast serves as a status symbol. Its size is related to the bird’s fighting strength, and thus to its dominance. Outside of breeding season, this black area reduces in size and males become less conspicuous.
Female house sparrows (right) are plainer than males
House sparrow chicks look like their mothers. However, this doesn’t last long! Barely eight weeks after hatching, young house sparrows lose their youthful plumage and, before winter, look just like an adult.
15-9-2018 MONTE CORONA, VALENCIA - BAND WINGED GRASSHOPPER (Genus Sphingonotus)
Bandwings, or band-winged grasshoppers, are the subfamily Oedipodinae of grasshoppers classified under the family Acrididae. They have a worldwide distribution and were originally elevated to full family status as the Oedipodidae. Many species primarily inhabit xeric weedy fields, and some are considered to be important locusts:
Locusta migratoria: the migratory locust
Chortoicetes terminifera: the Australian plague locust
Locustana pardalina the brown locust
These grasshoppers often have colorful hindwings that may be yellow or red and edged with black. Others have black hindwings with pale edges, and a few species (including the most economically important ones) have clear hindwings. The arolium is extremely small or absent.
When bandwings feel safe, they appear drab. When they feel threatened, they leap out to reveal bold and bright colors. Some predators might even mistake the blue-winged grasshopper for a butterfly. But when the predator looks for the grasshopper, it is hiding in the grass. Bandwings continue this process if the predator tries to attack them.

12-9-2018 ALBUFERA, VALENCIA - SQUACCO HERON (Ardeola ralloides)
The Squacco Heron, Ardeola ralloides, is a diminutive member of the heron family, measuring a mere 44–47 cm in length, with a compact body of 20–23 cm and a wingspan stretching 80–92 cm. This species is adorned with a buff-brown back and, during the summer months, adults boast elongated neck feathers that add to their allure.
In the field, one may identify the Squacco Heron by its stocky build, abbreviated neck, and stout bill. Its back is cloaked in a buff-brown hue. When in flight, the heron undergoes a remarkable transformation, revealing a predominantly white plumage that contrasts starkly with its resting appearance.
The Squacco Heron favors marshy wetlands in temperate regions for its habitat, where the water is warm and inviting.
Originating from the Old World, the Squacco Heron breeds in the southern reaches of Europe and extends into the Greater Middle East. When not breeding, it migrates to winter in the African continent.
This species is migratory by nature, seeking the warmer climates of Africa to spend the winter. It is seldom seen north of its breeding grounds. The Squacco Heron has been observed as a vagrant in the Fernando de Noronha islands and, on rarer occasions, in mainland South America. It nests in modest colonies, often in the company of other wading birds, and constructs its nests from sticks on platforms in trees or shrubs.
The Squacco Heron selects freshwater locales across Europe and the Middle East to breed, later migrating southward to the Sub-Saharan African region. During the breeding season, they lay a clutch of three to four eggs.
Adept at foraging, the Squacco Heron feeds on a diet consisting of fish, frogs, and insects, making the most of its wetland environment.
The IUCN Red List currently classifies the Squacco Heron as Least Concern, indicating a stable population without immediate threats to its survival.
Non-breeding Squacco Herons share certain physical characteristics with other heron species such as the Indian Pond Heron and the Malagasy Pond Heron, including tawny plumage, lighter streaking, a smaller bill, and narrower wing tips.
The Squacco Heron uses freshwater localities throughout Europe and the Middle East as breeding grounds to later migrate south to the Sub-Saharan African region. Non-breeding Squacco Herons share similar traits with other heron species like the Indian Pond Heron and Malagasy Pond Heron which show tawny color plumage, lighter streaking, smaller bill, and narrower wing tips.
The squacco heron is a migrant, wintering in Africa. It is rare north of its breeding range. The species has been recorded in Fernando de Noronha islands, and more rarely in mainland South America, as a vagrant. This is a stocky species with a short neck, short thick bill and buff-brown back. In summer, adults have long neck feathers. Its appearance is transformed in flight, when it looks very white due to the colour of the wings.
The squacco heron's breeding habitat is marshy wetlands in warm countries. The birds nest in small colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. Three to four eggs are laid. They feed on fish, frogs and insects.

13-9-2018 GANDIA, VALENCIA - EGYPTIAN BIRD GRASSHOPPER (Anacridium aegyptium)
Anacridium aegyptium, the Egyptian grasshopper or Egyptian locust, is a species of insect belonging to the subfamily Cyrtacanthacridinae.
Anacridium aegyptium var. rubrispinum Bei-Bienko, 1948 - Anacridium rubrispinum Bei-Bienko, 1948
A fairly common species, the Egyptian grasshopper is present in most of Europe, the Afrotropical realm, eastern Palearctic realm, the Near East, and North Africa, and has recently been observed in Cape Town, South Africa.
These grasshoppers inhabit trees and shrubs, scrub land, maquis, and orchards in warm and bright environments, at an elevation from sea level to 1,500 m.
Anacridium aegyptium is one of the largest European grasshoppers. Adult males grow up to 30–56 mm (1.2–2.2 in) long, while females reach 46–70 mm (1.8–2.8 in) in length. Their bodies are usually gray, brown, or olive-coloured, and their antennae are relatively short and robust. The tibiae of the hind legs are blue, while the femora are orange. The hind femora have characteristic dark marks. They are also easily identified by their characteristic eyes, which have vertical black and white stripes. Their pronota show a dorsal orange stripe and several small white spots. The wings are clear with dark marks.
This species is a folivore, essentially feeding on leaves of various plants. It is a solitary species, harmless to crops. Adults are mainly seen in August and September, but they are active throughout the year. After mating, these grasshoppers overwinter as adults. Spawning occurs in spring just under the soil surface and the nymphs appear in April. These grasshoppers undergo several molts. Nymphs differ from adults in appearance; their color varies from yellow to bright green and ocher and the wings are absent or small, as they are gradually developed after each molt.
