24-5-2020 GANDIA PUERTO, VALENCIA - EUROPEAN SERIN (MALE) (Serinus serinus)
%20(Serinus%20serinus)%2020.jpg)
The European serin, or simply the serin (Serinus serinus), is a diminutive member of the finch family, Fringillidae. This sprightly bird is the smallest within its family, closely related to the Atlantic canary. It is characterized by its short tail and a length that spans a mere 11 to 12 centimeters. The serin's plumage is a tapestry of nature's palette, with upper parts dappled in dark-streaked greyish green and a conspicuous yellow rump. The underparts are a canvas of yellow breast and white belly, both adorned with heavy streaks.
When attempting to identify the European serin, look for the male's radiant yellow face and breast, which stand out against the greenish backdrop of its feathers. The male also boasts yellow wing bars and yellow tail sides, which can be quite helpful in distinguishing it from similar species. Both sexes share a buzzing trill of a song that resonates through their Mediterranean habitats.
The European serin is partial to open woodland and cultivated areas, often with a sprinkling of conifers. These environments provide the perfect backdrop for breeding and foraging.
%20(Serinus%20serinus)%2021.jpg)
This species has a breeding range that extends across southern and central Europe and into North Africa. Populations along the southern and Atlantic coasts tend to be resident, while those in the north are migratory, seeking warmer climates in southern Europe during the winter months.
Outside of the breeding season, the European serin is a sociable creature, forming flocks that may sometimes mingle with other finch species. It is an active and often conspicuous bird, its presence easily announced by its distinctive trill.
The serin's song is a distinctive buzzing trill, a sound that becomes part of the ambient music in regions where these birds are common.
The European serin weaves its nest within the shelter of a shrub or tree, where it lays a clutch of 3 to 5 eggs. The chosen breeding habitats are often areas of open woodland and cultivation, with a preference for some conifers.
The diet of the European serin is predominantly seeds, but it does not shy away from including insects during the breeding season, providing essential protein for its young.
24-5-2020 GANDIA PUERTO, VALENCIA - PAINTED LADY BUTTERFLY (Vanessa cardui)
Vanessa cardui is the most widespread of all butterfly species. It is commonly called the painted lady, or formerly in North America the cosmopolitan.
V. cardui occurs in any temperate zone, including mountains in the tropics. The species is resident only in warmer areas, but migrates in spring, and sometimes again in autumn. It migrates from North Africa and the Mediterranean to Britain and Europe in May and June, occasionally reaching Iceland, and from the Red Sea basin, via Israel and Cyprus, to Turkey in March and April. The occasional autumn migration made by V. cardui is likely for the inspection of resource changes; it consists of a round trip from Europe to Africa.
For decades, naturalists have debated whether the offspring of these immigrants ever make a southwards return migration. Research suggests that British painted ladies do undertake an autumn migration, making 14,500 km (9,000 mi) round trip from tropical Africa to the Arctic Circle in a series of steps by up to six successive generations. The Radar Entomology Unit at Rothamsted Research provided evidence that autumn migrations take place at high altitude, which explains why these migrations are seldom witnessed.
In recent years, thanks to the activity of The Worldwide Painted Lady Migration citizen science project, led by the Barcelona-based Institute of Evolutionary Biology (Catalan: Institut de Biologia Evolutiva), the huge range of migration has begun to be revealed. For example, some butterflies migrated from Iceland to the Sahara desert, and even further south.
V. cardui is known for its distinct migratory behaviour. In California, they are usually seen flying from north to north-west. These migrations appear to be partially initiated by heavy winter rains in the desert where rainfall controls the growth of larval food plants. In March 2019, after heavy rain produced an abundance of vegetation in the deserts, Southern California saw these butterflies migrating by the millions across the state.
Similarly, heavier than usual rain during the 2018-2019 winter seems to have been the cause of the extraordinarily large migration observed in Israel at the end of March, estimated at a billion individual butterflies. Painted lady migration patterns are highly erratic and they do not migrate every year. Some evidence suggests that global climatic events, such as el Niño, may affect the migratory behaviour of the painted lady butterflies, causing large-scale migrations. The first noticeable wave of migration in eastern Ukraine was noted in the 20s of April 2019. From May 15, numbers began to grow and it was possible to observe hundreds of this species in the Kharkiv region of Ukraine, including in the city streets of Kharkiv.
24-5-2020 GANDIA PUERTO, VALENCIA - WAVYLEAF MULLEIN (Verbascum sinuatum)
Verbascum sinuatum, commonly known as the scallop-leaved mullein, the wavyleaf mullein, or Candela regia, is a species of perennial herbaceous plants in the genus Verbascum (mullein), growing in heavy soils in Central Asia and the Mediterranean region. It grows to 1.2–1.5 m (3.9–4.9 ft). The plant has an erect inflorescence stem, and is entirely covered with stellate hairs (trichomes) which are not pleasant to the touch.
In the winter, a rosette of broad-leaves grows at the base of the Scallop-leaved mullein and spreads itself on the ground (length 30–50 cm). In the spring, a leafless stalk grows from the base of the plant, splitting into many diagonal stems that can grow as much as 50 to 100 cm. in length, on which the flowers are located. The plant bears simple, emarginate leaves, and has a yellow lamp-shaped flower (hence its name Candela) of 5 petals, blossoming mostly in late May to August, although sometimes as late as October.
24-5-2020 MONTE CORONA, VALENCIA - WAVE MOTH (Idaea ostrinaria)
%2020.jpg)
Idaea ostrinaria (Coral-bordered Wave) is a small geometrid moth found in European, Mediterranean, and Western Asian xerophilous (dry) habitats, typically at 0–800m altitude. It features a characteristic coral-red bordered wing and is polyphagous, with larvae feeding on withered foliage and detritus from herbaceous plants like thyme (Thymus) and heliotrope (Heliotropium).
Key Facts about Idaea ostrinaria:
Scientific Classification: Belongs to the order Lepidoptera, family Geometridae, and subfamily Sterrhinae.
Habitat: Prefers dry, coastal areas, and warm, open landscapes.
Appearance: Known for its reddish or "coral-bordered" wing markings, often featuring a delicate, pale, or brownish-grey ground color.
Larval Diet: Polyphagous, meaning they eat a variety of plants, including Labiatae (mint family), Boraginaceae, Campanulaceae, Convolvulaceae, and Caryophyllaceae.
Range: Primarily found in South-West Europe, the Mediterranean region, and parts of Western Asia.
Flight Season: Frequently observed in late spring and summer months (e.g., June sightings).

23-5-2020 MONTE CORONA, VALENCIA - GREY LEAVED CISTUS (Cistus albidus)
%2020.jpg)
Cistus albidus, the grey-leaved cistus, is a shrubby species of flowering plant in the family Cistaceae, with pink to purple flowers, native to south-western Europe and western north Africa.
Cistus albidus grows up to 1 m (3 ft) tall. Its leaves are oblong to elliptical in shape, usually 2–5 cm (0.8–2.0 in) long by 0.5–2 cm (0.2–0.8 in) wide. They have three prominent veins and are densely covered with short hairs, producing a greyish-white appearance. The flowers are arranged in cymes of one to seven individual flowers, each 4–6 cm (1.6–2.4 in) across with five purple to pink petals and five sepals.
Cistus albidus is native to the west of Southern Europe and western North Africa, particularly around the Mediterranean, including Portugal, Spain, the Balearic Islands, France, Corsica, Italy, Sardinia, and Morocco.
23-5-2020 MONTE CORONA, VALENCIA - LARGE WALL BROWN BUTTERFLY (Lasiommata maera)
%2020.jpg)
Lasiommata maera, the large wall brown, is a butterfly in the family Nymphalidae.
The species is common in continental Europe. It is also present in the Urals, south western Siberia, Asia Minor, Syria, Iran, Central Asia and the Himalayas. It is absent from the United Kingdom. Its preferred habitats are edges of the forest, unmanaged clearings on forested areas, rocky dry areas and stony slopes, at an elevation of 0–2,000 metres (0–6,562 ft) above sea level.
Lasiommata maera has a wingspan of 44–56 millimetres (1.7–2.2 in). These large butterflies are quite variable in color and pattern. Usually the upperside is orange in the forewings and mostly brown in the hindwings. The forewings always show a single ocellus, while the hindwings bear two or three ocelli. The underside of the forewings is orange and the underside of the hindwings is marbled with gray brown. This species is quite similar to Lasiommata megera, that is smaller and has paler yellow-orange forewings. Seitz P. maera L. (= adrasta Dup.) (45 d). On an average larger than hiera, more evenly coloured, the black markings of the ground less prominent in the nymotypical form with a sooty brown disc; the forewing of the male more pointed, with longer costal margin and more oblique distal margin; on the underside of the forewing the distal band extends without interruption across the median veins to the hindmargin. The underside of the hindwing has a much purer ground-colour, i. e. there are less clouds and shadows between the various dentate lines which cross the disc.
23-5-2020 MONTE CORONA, VALENCIA - EUROPEAN GOLDFINCH (Carduelis carduelis)
%2020.jpg)
The European goldfinch is native to Europe, North Africa, and western and central Asia. It is found in open, partially wooded lowlands and is a resident in the milder west of its range, but migrates from colder regions. It will also make local movements, even in the west, to escape bad weather. It has been introduced to many areas of the world. It was introduced to Bermuda, Canada, the United States, Mexico, Peru, Argentina, Chile, the Falkland Islands, Uruguay, Brazil, South Africa, Australia, and New Zealand in the 19th century, and their populations quickly increased and their range expanded greatly. In Australia, they now occur from Brisbane to the Eyre Peninsula, and are also spread throughout New Zealand. In the United States, they have become established in the western Great Lakes region.

22-5-2020 PEGO MARJAL, ALICANTE - LITTLE EGRET (Egretta garzetta)
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".

21-5-2020 MONTE CORONA, VALENCIA - SPOTTED FLYCATCHER (Muscicapa striata)
%2020.jpg)
Spotted flycatchers are one of our summer migrants that spend the winter in Africa. They are one of the latest migrants to reach us, with a few trickling into the country from late April and most arriving from mid-May.
Despite arriving relatively late, spotted flycatchers manage to rear two broods of young before departing at the end of August. The success of the second clutch is increased by fewer eggs being laid, meaning less mouths to fill. They will nest in gardens but the nest is usually well hidden on ledges or behind climbing plants.
Spotted flycatchers prefer large flying insects, including flies and butterflies. However, if the weather is cool and insects aren’t flying, they will take smaller invertebrates from leaves and branches. If poor weather persists, many nests fail as these smaller invertebrates tend to be eaten by the parents rather than fed to the young.
21-5-2020 MONTE CORONA, VALENCIA - WALCKENAER'S FEATHER LEGGED SPIDER (Uloborus walckenaerius)
%2019.jpg)
Uloborus walckenaerius, also known as the feather-legged spider, is a cribellate spider in the family Uloboridae. Like all spiders in this family, they do not have venom glands and immobilize their prey with over 140 m of thread. They are named in honor of Charles Athanase Walckenaer.
It is commonly known as the fluffy hackled orb-web spider.
Adult females have a body length of 3.5–6 mm (0.14–0.24 in), males 3–4 mm (0.12–0.17 in). They have a dark grey prosoma, covered with white hairs, leaving some dark bands uncovered. They have eight eyes, arranged in two almost parallel rows of four, with the anterior lateral eyes on the front corners of the head.
%2020.jpg)
The abdomen is greyish-white in colour, with a continuation of the pattern on the carapace. It bears a brown median line, with alternating white and brown bands on either side. There are fluffy white tufts of hair on the white bands, which are very distinct from the side. The legs range from dark grey-brown to reddish-brown, with faint, white annulations. The front two pairs of legs are significantly longer than the rear pairs.
%2021.jpg)
Uloborus walckenaerius has a widespread distribution throughout the Palearctic region and has been introduced to Cape Verde, Saint Helena, and South Africa.
The spider lives in warm, open terrain, like heathland, and weaves horizontal cribellate orb webs close to the ground. A stabilimentum is sometimes present, and the spider hangs beneath the hub.
21-5-2020 VILLALONGA CAMPO, VALENCIA - SMALL WHITE BUTTERFLY (Pieris rapae)
%2020.jpg)
In appearance it looks like a smaller version of the large white (Pieris brassicae). The upperside is creamy white with black tips on the forewings. Females also have two black spots in the center of the forewings. Its underwings are yellowish with black speckles. It is sometimes mistaken for a moth due to its plain appearance. The wingspan of adults is roughly 32–47 mm (1.3–1.9 in).
Pieris rapae has a wingbeat frequency averaging 12.8 flaps per second.
%2021.jpg)
The small white will readily lay eggs on both cultivated and wild members of the cabbage family, such as charlock (Sinapis arvensis) and hedge mustard (Sisymbrium officinale). P. rapae is known to lay eggs singularly on the host plant. The egg is characterized by a yellowish color and 12 longitudinal ridges. The egg production peaks about a week after adulthood in lab and the female can live up to 3 weeks.
Females tend to lay fewer eggs on plants in clumps than on isolated plants. It has been suggested that isothiocyanate compounds in the family Brassicaceae may have been evolved to reduce herbivory by caterpillars of the small white.cepted because the small white has later been shown to be immune to the isothiocyanate forming reaction due to a specific biochemical adaptation. In contrast, the small white and relatives seem to have evolved as a consequence of this biochemical adaptation to the isothiocyanate-forming glucosinolates.

19-5-2020 MONTE CORONA, VALENCIA - SPOTTED FLYCATCHER (Muscicapa striata)
%2020.jpg)
The Spotted Flycatcher, Muscicapa striata, is a modestly adorned yet charming small passerine bird belonging to the Old World flycatcher family. It is a migratory species, breeding across Europe and the Palearctic as far as Siberia, and spending the winter months in Africa and southwestern Asia. Despite its widespread presence, there is concern over its decline in certain areas.
Adult Spotted Flycatchers possess grey-brown upperparts and a somewhat pallid underbelly. Their crown and breast are streaked, which is the origin of their common name. They have short, black legs and a black bill shaped to suit their insectivorous diet. Juveniles can be distinguished by their browner plumage and the presence of spots on their upperparts.
These birds favor deciduous woodlands, parks, and gardens, particularly those with open spaces amidst trees.

17-5-2020 MONTE CORONA, VALENCIA - BLUE ROCK THRUSH (FEMALE) (Monticola solitarius)
%20(Monticola%20solitarius)%2021.jpg)
The female blue rock thrush (Monticola solitarius) is significantly different in appearance from the vibrant blue male, featuring a more "conservative" brownish-grey plumage that provides camouflage in its rocky habitats. While they are often less conspicuous, they play the primary role in incubating eggs and caring for the young.
Appearance & IdentificationColoration: Unlike the deep metallic blue of the male, females are primarily grey-brown on their upperparts.
Underparts: Their bellies and chests are lighter and exhibit a distinctive mottled or scaly pattern (barred with brown and pale buff).
%20(Monticola%20solitarius)%2022.jpg)
Subtle Details: Some females may show a very subtle bluish tinge on their back, wings, or tail, especially in certain light or depending on the subspecies.
Size: They are medium-sized birds, roughly the size of a blackbird, measuring approximately 21–23 cm (8.3–9.1 inches) in length.
Nesting & BreedingPrimary Incubator: The female takes the lead in incubating the eggs, a process that typically lasts between 14 and 16 days.
Egg Details: She usually lays a clutch of 3 to 5 eggs (sometimes up to 6) which are pale blue or bluish-green and often marked with fine reddish spots.
Nest Construction: Both sexes contribute to building the nest using twigs, dry grass, and fine roots, typically hidden in rock crevices, cliffs, or old stone buildings.
Broods: Depending on the region, a female may raise two to three broods per season, starting as early as late March.
