3-7-2020 MOROS MARJAL, VALENCIA - YELLOW HORNED POPPY (Glaucium flavum)
It grows in coastal habitats on shingle banks and beaches, but can also be found on cliff tops and in sand dunes.
It produces an orange foul smelling sap, if cut open. All parts of the plant, including the seeds, are toxic, and can cause a wide range of symptoms (if eaten), and respiratory failure, resulting in death.
Glaucine is the main alkaloid component in Glaucium flavum. Glaucine has bronchodilator and antiinflammatory effects, acting as a PDE4 inhibitor and calcium channel blocker, and is used medically as an antitussive in some countries. Glaucine may produce side effects such as sedation, fatigue, and a hallucinogenic effect characterised by colourful visual images, and as a recreational drug. For a detailed bibliography on glaucine and Glaucium flavum see: National Agricultural Library. (Glaucium flavum entry)
In the past, it was known in Hampshire, UK as 'squatmore', and the roots were used to treat bruises. Also pains in the breast, stomach and intestines.
2-7-2020 ROSSELL, CASTELLON - IBERIAN MARBLE WHITE BUTTERFLY (Melanargia lachesis)
%2020-topaz-upscale-1.4x.jpg)
Melanargia lachesis, the Iberian marbled white, is a butterfly species belonging to the family Nymphalidae.
It can be found on the Iberian Peninsula and the south of France.
The length of the forewings is 25–28 mm. Seitz- M. lachesis Hbn. (= nemausica Esp.) (38b). Lighter than galathea, even than the lightest forms of the same. The black discocellular anguliform spot of the forewing constricted where it is bent. Hindwing entirely white, apart from the interrupted submarginal band; the base very sparingly dusted, the markings of the underside however shine through in the male. In Spain, Portugal and South France. – The specimens with creamy yellow ground-colour, which are somewhat rarer than the chalky white canigulensis Obth.; from the Pyrenees.
%2021-topaz-upscale-1.4x.jpg)
The butterflies fly in one generation from June to August.They occur from the plain to about 1,600 meters above sea level. They prefer dry, flowering, natural meadows that can also be overgrown with bushes. The larvae feed on various grasses.
The Iberian Marbled White (Melanargia lachesis) is a distinctive black-and-white butterfly native to the Iberian Peninsula and southern France. Despite its common name, it is actually part of the "Brown" family (Satyrinae) rather than the true whites.
Key FactsAppearance: It features a striking chequered black and white pattern. It is distinguished from the similar Marbled White (M. galathea) by having less black at the base of its forewings and a generally whiter appearance.
%2022-topaz-upscale-1.4x.jpg)
Size: This is a relatively large butterfly, with some individuals reaching a wingspan of up to 6 cm.
Distribution: It is almost exclusively found in Spain, Portugal, and southern France as far as the Rhône valley. In northern Spain and southern France, its range overlaps with its cousin, the common Marbled White.
Habitat: It thrives in hot, dry, flowery grasslands and meadows, often on calcareous soils.Diet: Adults frequently feed on the nectar of purple flowers like knapweed, thistles, and scabious.
Life Cycle:It is univoltine, meaning it produces only one generation per year, with adults flying between June and August.Caterpillars feed on various grass species (such as Festuca and Brachypodium) and hibernate through the winter while still small.Unusually, females do not attach their eggs to plants; they drop them randomly onto the ground while flying over tall grasses.

2-7-2020 ROSSELL, CASTELLON - CORN BUNTING (Emberiza calandra)
The corn bunting (Emberiza calandra) is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae. This is a large bunting with heavily streaked buff-brown plumage. The sexes are similar but the male is slightly larger than the female. Its range extends from Western Europe and North Africa across to northwestern China.
The corn bunting was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae and retains its original binomial name of Emberiza calandra. The type locality is Sweden. The genus name Emberiza is from Old German Embritz, a bunting. The specific calandra is from Ancient Greek kalandros, the calandra lark. The corn bunting has sometimes been placed in its own monotypic genus Miliaria.
This is an unusual bunting because the plumages of the sexes are similar in appearance, though the male is approximately 20% larger than the female. This large bulky bunting is 16–19 cm long, with a conspicuously dark eye and yellowish mandibles. Males lack any showy colours, especially on the head, which is otherwise typical of genus Emberiza. Both sexes look something like larks, being streaked grey-brown above with whitish underparts. The underparts are streaked over the flanks and breast, and the streaking forms gorget around the throat. The lesser wing coverts are distinctively dark and white-tipped. The tail is plain brown.
The song of the male is a repetitive metallic sound, usually likened to jangling keys, which is given from a low bush, fence post or telephone wires.
It breeds across southern and central Europe, north Africa and Asia across to Kazakhstan. It is mainly resident, but some birds from colder regions of central Europe and Asia migrate southwards in winter.
The corn bunting is a bird of open country with trees, such as farmland and weedy wasteland. It has declined greatly in north-west Europe due to intensive agricultural practices depriving it of its food supply of weed seeds and insects, the latter especially vital when feeding the young. It has recently become extinct in Wales and Ireland, where it was previously common.
Its natural food consists mainly of seeds but also includes insects such as crickets, especially when feeding young.
Males defend territories in the breeding season and can be polygynous, with up to three females per breeding male. The population sex ratio is generally 1:1, which means some males remain unmated during a season. Males play only a small role in parental care; they are not involved in nest building or incubation, and only feed the chicks when they are over half grown.
The nest is made of grass, lined with hair or fine grass, and is usually built on the ground. Average clutch size is four, but commonly varies from three to five, occasionally six.

29-6-2020 VILLALONGA RESERVOIR, VALENCIA - WHITE FEATHERLEG DAMSELFLY (Platycnemis latipes)
As well as the diagnostic broad, 'feathery' white legs, it generally has a paler blue body to help distinguish it from the other blue damselflies. The pale chestnut wing spots are also characteristic. Immature males and females are mostly creamy white (form lactea). Females take on a very pale green colour on maturity.
This damselfly favours slow moving rivers and canals with luxuriant vegetation.
It can be seen from mid May to mid August.
The males engage in a courtship display to woo the female, raising its front white legs in front of the female as part of the act.
In Britain it is found in mainly lowland areas, up to the Midlands. It is uncommon but can become locally frequent.
29-6-2020 VILLALONGA RESERVOIR, VALENCIA - EUROPEAN GOLDFINCH (JUVENILE) (Carduelis carduelis)
%20(Carduelis%20carduelis)%2020.jpg)
The European goldfinch, or simply goldfinch (Carduelis carduelis), is a small, vibrant passerine bird belonging to the finch family. This charming avian species is adorned with a striking red face, encircled by black markings near the eyes, and a black-and-white head. The back and flanks exhibit a warm buff or chestnut brown, while the wings are black with a prominent yellow bar. The tail is black, and the rump is a contrasting white. Males and females are similar in appearance, though the male boasts a slightly more extensive red mask.
Upon closer inspection, one can discern the male goldfinch by its larger, more vivid red mask that extends just beyond the eye. The female's red face does not reach past the eye, and her shoulder feathers are brown, as opposed to the male's black. The bill is ivory-colored, long, and pointed, and the tail is forked. Juveniles can be identified by their plain heads and greyer backs, but the yellow wing stripe is a clear indicator of their species.
The European goldfinch favors open, partially wooded lowlands and is a resident in the milder western parts of its range. In colder regions, it migrates to escape the harsh weather.
%20(Carduelis%20carduelis)%2021.jpg)
Native to Europe, North Africa, and western and central Asia, the European goldfinch has also been introduced to various regions across the globe, including Australia, New Zealand, and Uruguay.
The European goldfinch is known for its sociable nature, often forming flocks in the winter. It is a frequent visitor to bird feeders, particularly in the colder months.
The goldfinch's song is a delightful, silvery twittering, while its call is a melodic tickeLIT. Its song comprises a tinkling medley of trills and twitters, always including the tri-syllabic call phrase.
The female goldfinch solely constructs the nest, which is often situated several meters above ground, camouflaged by leaves. The nest is made of mosses and lichens, lined with plant down, and secured with spider silk. Eggs are laid at daily intervals, typically resulting in a clutch of 4-6 eggs. Incubation lasts 11-13 days, with the female being fed by the male. Both parents feed the chicks, which fledge 13-18 days after hatching.
Goldfinches have a preference for small seeds, such as those from thistles and teasels, but will also consume insects when feeding young. They are particularly drawn to bird feeders offering niger seed.
29-6-2020 MONTE CORONA, VALENCIA - SPECKLED WOOD BUTTERFLY (Pararge aegeria)
The speckled wood (Pararge aegeria) is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic realm. The species is subdivided into multiple subspecies, including Pararge aegeria aegeria, Pararge aegeria tircis, Pararge aegeria oblita, and Pararge aegeria insula. The color of this butterfly varies between subspecies. The existence of these subspecies is due to variation in morphology down a gradient corresponding to a geographic cline.
The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on ecological conditions. The monandrous female must choose which type of male can help her reproduce successfully. Her decision is heavily influenced by environmental conditions.

28-6-2020 POTRIES, VALENCIA - BROAD SCARLET 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.
28-6-2020 MONTE CORONA, VALENCIA - THE BORDERED STRAW MOTH (Heliothis peltigera)
%2020.jpg)
Heliothis peltigera, also known as the bordered straw, is a species of moth of the family Noctuidae.
The Greek epithet "Heliothis" means "scorched by the sun", while the Latin species name peltigera means wearing a small shield, with reference to the reniform marking on the forewings.
This species can be found in Southern Europe and the Near East, but it is present further north too, because it is a regular migratory species northbound. It is also present in most of Africa (Algeria, Chad, Egypt, Eritrea, Gambia, Libya, Mauritania, Morocco, Niger, Somalia, Tunisia) and in Asia, ranging to China and Laos.
This heat-loving species occurs mainly on hot wastelands and warm slopes.
Heliothis peltigera has a wingspan of 29–40 mm and forewings reaching a length of 16–19 mm. These moths are rather variable in pattern and colour.
28-6-2020 VILLALONGA RESERVOIR, VALENCIA - YELLOW LEGGED GULL (Larus michahellis)
The yellow-legged gull is a large gull found in Europe, the Middle East and North Africa, which has only recently achieved wide recognition as a distinct species. It was formerly treated as a subspecies of either the Caspian gull L. cachinnans, or more broadly as a subspecies of the herring gull L. argentatus.The genus name is from Latin Larus which appears to have referred to a gull or other large seabird, and the species name honours the German zoologist Karl Michahelles.
The yellow-legged gull is a large gull, though the size does vary, with the smallest females being scarcely larger than a common gull and the largest males being roughly the size of a great black-backed gull. They range in length from 52 to 68 cm (20 to 27 in) in total length, from 120 to 155 cm (47 to 61 in) in wingspan and from 550 to 1,600 g (1.21 to 3.53 lb) in weight. Among standard measurements, the wing chord is 40.8 to 47.2 cm (16.1 to 18.6 in), the bill is 4.6 to 6 cm (1.8 to 2.4 in) and the tarsus is 5.6 to 7.5 cm (2.2 to 3.0 in). Adults are externally similar to herring gulls but have yellow legs. They have a grey back, slightly darker than herring gulls but lighter than lesser black-backed gulls.
They are much whiter-headed in autumn, and have more extensively black wing tips with few white spots, just as lesser black-backed. They have a red spot on the bill as adults, like the entire complex. There is a red ring around the eye like in the lesser black-backed gull but unlike in the herring gull which has a dark yellow ring.
First-year birds have a paler head, rump and underparts than those of the herring gull, more closely resembling first-year great black-backed gulls in plumage. They have a dark bill and eyes, pinkish grey legs, dark flight feathers and a well-defined black band on the tail. They become lighter in the underparts and lose the upperpart pattern subsequently. By their second winter, birds are essentially feathered like adults, save for the patterned feathers remaining on the wing coverts. However, their bill tips are black, their eyes still dark, and the legs are a light yellow flesh colour.
The call is a loud laugh which is deeper and more nasal than the call of the herring gull.
The breeding range is centred on the Mediterranean Sea. In North Africa, it is common in Morocco, Algeria and Tunisia and increasing in places. Recent breeding has occurred in Libya and Egypt. In the Middle East, a few breed in Israel and Syria with larger numbers in Cyprus and Turkey. In Europe, there are colonies all along the Mediterranean coast, and also on the Atlantic islands and coasts north to Brittany and west to the Azores. It also breeds on the western side of the Black Sea; here it overlaps with the Caspian gull but there is a difference in habitat, with the yellow-legged gull preferring sea cliffs and the Caspian gull flatter shores. In recent decades birds have spread north into central and western Europe. One to four pairs have attempted to breed in southern England since 1995 (sometimes hybrid pairs with lesser black-backed gulls), though colonisation has been very slow.
28-6-2020 VILLALONGA RESERVOIR, VALENCIA - EURASIAN REED WARBLER (Acrocephalus scirpaceus)
The Common Reed Warbler, Acrocephalus scirpaceus, is a medium-sized warbler measuring approximately 13 cm in length with a wingspan ranging from 17 to 21 cm. It exhibits an unstreaked brown back with buff underparts. Both sexes are identical in appearance, which is typical for warblers. Juveniles can be distinguished by their richer buff underparts. The species is characterized by a flattened forehead and a robust, pointed bill.
When identifying the Common Reed Warbler, look for its brown, unstreaked back and buff underparts. The bird's supercilium is less pronounced than that of the larger Great Reed Warbler. In flight, observe the wing-span and listen for its distinctive song.
This species is almost exclusively found in reed beds, often with interspersed bushes, providing it with the necessary cover and nesting sites.
The Common Reed Warbler breeds across Europe into the temperate western Palaearctic and is migratory, wintering in sub-Saharan Africa. It is also a resident species in large parts of Africa.
Males typically arrive at breeding grounds a few weeks before females. The species is generally monogamous, with pairs raising up to two broods per season. It is known to be brood parasitized by the Common Cuckoo.
The song of the Common Reed Warbler is a distinctive slow, chattering "jit-jit-jit" with acrocephaline whistles and mimicry.
Nests are built by the female over water, often in reeds, and are deep cylindrical cups. Clutches usually contain three to five pale green eggs with olive or grey speckles. Both parents incubate the eggs, which hatch after 9-12 days. Fledglings leave the nest after 10-12 days but are fed by parents for an additional 10-14 days.
The Great Reed Warbler is similar in appearance but is larger and has a more pronounced supercilium.
The Common Reed Warbler is primarily insectivorous but may occasionally consume plant material such as berries.

27-6-2020 MARXUQUERA, VALENCIA - RED RUMPED SWALLOW (Cecropis daurica)
%2020.jpg)
The Red-rumped Swallow (Cecropis daurica) is a small, graceful passerine bird, a member of the swallow family. It is characterized by its blue upperparts and dusky underparts, with a distinctive pale or reddish rump, face, and neck collar. Unlike the Barn Swallow, it lacks a breast band but features black undertails. Its wings are broad yet pointed, allowing for swift and agile flight.
To identify the Red-rumped Swallow, look for its darker underparts compared to the Barn Swallow, and the absence of a breast band. The rump is pale or reddish, providing a stark contrast to the blue upperparts. The bird's flight is fast, with frequent swoops as it pursues airborne insects.
This species is often found in open hilly country, where it can be seen gracefully hawking for insects over grasslands. It is also known to adapt to human structures, nesting under cliff overhangs, on buildings, and bridges.
%2021.jpg)
The Red-rumped Swallow has a wide distribution, breeding in temperate southern Europe and Asia, from Portugal and Spain to Japan, India, Sri Lanka, and tropical Africa. While the Indian and African populations are resident, European and other Asian birds are migratory, wintering in Africa or India.
These swallows are gregarious outside the breeding season, often seen in large numbers on the plains of India. They do not typically form large breeding colonies but are known to be social. Their flight is characterized by swift, agile movements as they feed on insects in the air.
The Red-rumped Swallow communicates with a series of chirps and trills, a delightful symphony that fills the air especially during the breeding season.
The Red-rumped Swallow constructs quarter-sphere nests with a tunnel entrance, using mud collected in their beaks. They lay 3 to 6 eggs and prefer to nest under cliff overhangs or on human-made structures.
This species is an aerial insectivore, feeding on insects caught in flight. They are adept at catching their prey mid-air, often following cattle or taking advantage of grass fires to find insects.

24-6-2020 RIVER JUCAR, RIOLA, VALENCIA - EUROPEAN MOORHEN (Gallinula chloropus)
%2020.jpg)
The common moorhen (Gallinula chloropus), also known as the waterhen or swamp chicken, is a bird species in the rail family (Rallidae). It is distributed across many parts of the Old World.
The common moorhen lives around well-vegetated marshes, ponds, canals and other wetlands. The species is not found in the polar regions or many tropical rainforests. Elsewhere it is likely the most common rail species, except for the Eurasian coot in some regions.
The closely related common gallinule of the New World has been recognized as a separate species by most authorities, starting with the American Ornithologists' Union and the International Ornithological Committee in 2011.
The moorhen is a distinctive species, with predominantly black and brown plumage, with the exception of a white under-tail, white streaks on the flanks, yellow legs and a red frontal shield. The bill is red with a yellow tip. The young are browner and lack the red shield. The frontal shield of the adult has a rounded top and fairly parallel sides; the tailward margin of the red unfeathered area is a smooth waving line. In the related common gallinule (Gallinula galeata) of the Americas, the frontal shield has a fairly straight top and is less wide towards the bill, giving a marked indentation to the back margin of the red area.
%2021.jpg)
The common moorhen gives a wide range of gargling calls and will emit loud hisses when threatened. A midsized to large rail, it can range from 30 to 38 cm (12 to 15 in) in length and span 50 to 62 cm (20 to 24 in) across the wings. The body mass of this species can range from 192 to 500 g (6.8 to 17.6 oz).
This is a common breeding and resident bird in marsh environments, rivers, well-vegetated lakes and even in city parks. Populations in areas where the waters freeze, such as eastern Europe, will migrate to more temperate climates. In China, common moorhen populations are largely resident south of the Yangtze River, whilst northern populations migrate in the winter, therefore these populations show high genetic diversity.
This species will consume a wide variety of vegetable material and small aquatic creatures. They forage beside or in the water, sometimes walking on lilypads or upending in the water to feed. They are often secretive, but can become tame in some areas. Despite loss of habitat in parts of its range, the common moorhen remains plentiful and widespread.
24-6-2020 ULLAL DE BALDOVI, VALENCIA - PERSIAN SILK TREE (Albizia julibrissin)
Albizia julibrissin, the Persian silk tree, pink silk tree, or mimosa tree, is a species of tree in the Fabaceae family, native to southwestern and eastern Asia.
It was introduced to Europe in the mid-18th century by Italian nobleman Filippo degli Albizzi, and the name of its entire genus Albizzia is given after him. The specific epithet julibrissin is a corruption of the Persian word gul-i abrisham (گل ابریشم), which means "silk flower" (from gul گل "flower" + abrisham ابریشم "silk").
Albizia julibrissin is known by a wide variety of common names, such as Persian silk tree and pink siris. It is also called Lankaran acacia or bastard tamarind, though it is not too closely related to either genus. The species is called Chinese silk tree, silk tree or mimosa in the United States, which is misleading—the former can refer to any species of Albizia which is most common in any one locale; and, although once included in Mimosa, neither is it very close to the Mimoseae. To add to the confusion, several species of Acacia, notably Acacia baileyana and Acacia dealbata, are also known as "mimosa" (especially in floristry), and many Fabaceae trees with highly divided leaves are called thus in horticulture.
