30-10-2017 BENIRRAMA, ALICANTE - EUROPEAN ROBIN (Erithacus rubecula)

The European robin (Erithacus rubecula), known simply as the robin or robin redbreast in Great Britain and Ireland, is a small insectivorous passerine bird, a member of the chat subfamily of the Old World flycatcher family. It is a plucky little bird, with a length of about 12.5–14.0 cm and a weight of 16–22 g. Both sexes are similarly adorned with an orange breast and face, lined with grey, brown upper-parts, and a whitish belly.

Adult robins can be identified by their orange breast and face, bordered by a bluish-grey on the sides of the neck and chest. The upperparts are brownish, or olive-tinged in British birds, and the belly is whitish. The bill and eyes are black. Juvenile robins are distinguishable by their spotted brown and white plumage, with patches of orange gradually appearing as they mature.

The European robin is a bird of diverse habitats, found in woodlands, gardens, and parks across its range. It is particularly associated with areas where the soil is dug or disturbed, allowing it easy access to its invertebrate prey.

This bird has a wide distribution across Europe, extending east to Western Siberia and south to North Africa. It is sedentary in most of its range except the far north, where it is migratory.

The robin is diurnal and is known for its boldness in human presence, often seen investigating gardeners at work. It is territorial, with males known to fiercely defend their territory. The robin's diet is primarily composed of insects and worms, but it will also consume berries and fruit, especially in autumn and winter.

The robin's song is a delightful fluting warble, more plaintive during the winter months. Both sexes sing, with the male's song typically starting before dawn and ending after dusk. Urban robins may sing at night, possibly to avoid noise pollution during the day.

Robins are versatile in their choice of nesting sites, often opting for unusual locations such as nooks in machinery or even discarded clothing. They typically lay two or three clutches of eggs per season, with the eggs being cream, buff, or white and speckled with reddish-brown.

The European robin is unique among the Erithacus genus, with its closest relatives being the Japanese robin and the Ryukyu robin, which are now placed in a different genus.

Robins primarily feed on insects, spiders, and worms. During colder months, their diet is supplemented with berries and fruit. They are also known to visit bird tables for seed mixtures and suet.

The European robin is classified as Least Concern by the IUCN, with a stable and possibly increasing population. It does not face any significant threats that would warrant concern for its long-term survival.

30-10-2017 BENIRRAMA, ALICANTE - WALL BROWN BUTTERFLY (Lasiommata megera)

Lasiommata megera, the wall or wall brown, is a butterfly in the family Nymphalidae (subfamily Satyrinae). It is widespread in the Palearctic realm with a large variety of habitats and number of generations a year.

The species lives in North Africa, Europe, the Caucasus, Asia Minor, the Middle East, western Siberia, northern Tian Shan, Dzungarian Alatau, Kazakhstan and Dzungaria.

Habitats include forest edges and clearings, shrubby areas in ravines and river valleys and sparse woodlands. It is also found in mountain habitats up to 0–3,000 metres (0–9,843 ft) above sea level.

The imago flies from April to October in two or three generations depending on locality and altitude. The larva feeds on grasses in the genera Festuca, Bromus, Deschampsia, Poa, Dactylis and Brachypodium.

30-10-2017 BENIRRAMA, ALICANTE - HOUSE SPARROW (FEMALE) (Passer domesticus)

The house sparrow (Passer domesticus) is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of 16 cm (6.3 in) and a mass of 24–39.5 g (0.85–1.39 oz). Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus Passer, the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird.

The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, polar regions, and hot, dry deserts far away from human development. For sustenance, the house sparrow routinely feeds at home and public bird feeding stations, but naturally feeds on the seeds of grains, flowering plants and weeds. However, it is an opportunistic, omnivorous eater, and commonly catches insects, their larvae, caterpillars, invertebrates and many other natural foods.

Because of its numbers, ubiquity, and association with human settlements, the house sparrow is culturally prominent. It is extensively, and usually unsuccessfully, persecuted as an agricultural pest. It has also often been kept as a pet, as well as being a food item and a symbol of lust, sexual potency, commonness, and vulgarity. Though it is widespread and abundant, its numbers have declined in some areas. The animal's conservation status is listed as least concern on the IUCN Red List. 

30-10-2017 BENIRRAMA, ALICANTE - COMMON DARTER DRAGONFLY (FEMALE) (Sympetrum striolatum)

The common darter (Sympetrum striolatum) is a dragonfly of the family Libellulidae native to Eurasia. It is one of the most common dragonflies in Europe, occurring in a wide variety of water bodies, though with a preference for breeding in still water such as ponds and lakes. In the south of its range adults are on the wing all year round.

Sympetrum species are not easy to tell apart and in most areas more than one Sympetrum species will occur. Females and teneral individuals have light yellow thorax and abdomen. Males turn red as they mature. Females darken with age, becoming a dark chocolate brown, and sometimes develop a blue colouration to the bottom of the abdomen. The wings also develop a brown tinge with age. In all cases the legs have a cream or yellow stripe on a black background - this is a diagnostic feature of this species. The pterostigma of the females can be red, blue, pale blue or brown.

30-10-2017 BENIRRAMA, ALICANTE - EURASIAN GRIFFON (Gyps fulvus)

The Eurasian griffon vulture, Gyps fulvus, is a majestic bird of prey belonging to the Accipitridae family. It is a large Old World vulture, known for its impressive wingspan ranging from 2.3 to 2.8 meters. The males of the nominate race weigh between 6.2 and 10.5 kilograms, while females are approximately the same weight. The Indian subspecies, G. f. fulvescens, averages around 7.1 kilograms. These vultures are characterized by their white head, broad wings, and short tail feathers, with a distinctive white neck ruff and a yellow bill. The buff body and wing coverts provide a stark contrast to their darker flight feathers.

When identifying the Eurasian griffon vulture, look for its large size, broad wings, and short tail. The white head and neck ruff, along with the yellow bill, are key features. In flight, the contrast between the buff-colored body and the dark flight feathers is quite noticeable.

These vultures are typically found in mountainous regions where they breed on crags and cliffs. They are also known to inhabit open areas where they can soar in search of carrion.

The Eurasian griffon vulture has a wide range that includes southern Europe, north Africa, and parts of Asia. Notable populations can be found in countries such as Italy, Croatia, Ireland, Cyprus, Israel, Greece, France, Belgium, the Netherlands, Germany, Serbia, Austria, Spain, France, Portugal, Armenia, and Russia.

Griffon vultures are social birds, often seen soaring in flocks. They are scavengers, primarily feeding on the carcasses of dead animals. These vultures are known to grunt and hiss at roosts or when feeding. They are mostly resident birds, with some populations forming loose colonies.

Eurasian griffon vultures breed on mountain crags, laying a single egg. They may form colonies, and the population is mostly resident throughout the year.

The Eurasian griffon vulture should not be confused with the Rüppell's griffon vulture (Gyps rueppellii) or the Himalayan griffon vulture (Gyps himalayensis). It is also closely related to the white-backed vulture (Gyps africanus).

As scavengers, these vultures feed mostly on carrion, which they locate by soaring over open landscapes. They have been observed to increase their feeding rates when more food is available.

The Eurasian griffon vulture is currently listed as Least Concern on the IUCN Red List. However, the species has faced threats from the consumption of poisoned baits. Conservation efforts are focused on increasing awareness and reducing the use of illegal poisons.

29-10-2017 MONTE CORONA, VALENCIA - EUROPEAN ROBIN (Erithacus rubecula)

The European robin (Erithacus rubecula), known simply as the robin or robin redbreast in Great Britain and Ireland, is a small insectivorous passerine bird, a member of the chat subfamily of the Old World flycatcher family. It is a plucky little bird, with a length of about 12.5–14.0 cm and a weight of 16–22 g. Both sexes are similarly adorned with an orange breast and face, lined with grey, brown upper-parts, and a whitish belly.

Adult robins can be identified by their orange breast and face, bordered by a bluish-grey on the sides of the neck and chest. The upperparts are brownish, or olive-tinged in British birds, and the belly is whitish. The bill and eyes are black. Juvenile robins are distinguishable by their spotted brown and white plumage, with patches of orange gradually appearing as they mature.

The European robin is a bird of diverse habitats, found in woodlands, gardens, and parks across its range. It is particularly associated with areas where the soil is dug or disturbed, allowing it easy access to its invertebrate prey.

29-10-2017 MONTE CORONA, VALENCIA - EGYPTIAN LOCUST (Anacridium aegyptium)

Large and impressive the Egyptian Grasshopper is a common species around the Mediterranean. They are vegetarian and completely harmless to people, other than that they are often so well camouflaged they may startle you when they suddenly fly up in front of you as you walk.

Adult female Egyptian grasshoppers can reach a length of 6.5cm.

The male is smaller, growing to around 3.5cm. The antennae of both sexes are relatively short and robust. The spiny projections on the underside of the legs help the insect to cling to vertical surfaces.

The antennae are quite short and robust, the eye is diagnostic of the species - it is always striped. The pronuptum (the shield type shape behind the head, as seen in the image above) is distinctly ridged, like plates of armour.

The adult grasshoppers are generally grey, brown or olive coloured with variable patterns that allows them good camouflage against tree bark and other vegetation; green individuals may occur, but very infrequently.

If they are disturbed these grasshoppers can use their strong back legs for jumping

Both sexes fly very well at a good speed over short distances and can frequently be seen – and heard- doing so, making a distinctive ‘clattering’ sound.  

Eggs are laid in the spring just under the soil surface. The young grasshoppers are tiny when they first emerge as nymphs and can be found in a variety of colours including bright green, shades of brown and even a pale orange, a selection of which may be found feeding communally. They can be told apart from other grasshoppers by the shape and size of the pronotum  and if you can get a close enough look, they have the diagnostic vertical striped pattern in their eyes, which is visible at all growth stages.

The growing grasshoppers will undergo several moults during their first months; in the early stages the wings are only visible as tiny wing buds that enlarge gradually at each moult. It is not until they go through their last moult to adulthood that the wings develop fully.

Egyptian Grasshoppers can be found in a variety of habitats preferring warm dry areas of scrub land, maquis and areas with trees, including orchards and gardens; their diet consists of various leaves and a single insect will cause very little damage. They spend a lot of their time hiding amongst foliage and branches of shrubs and trees, and when they catch sight of you they will move slowly to the far side of  their ‘perch’, hoping you have not seen them.

This species is active throughout the year and can be found from sea-level to 1,500m.

29-10-2017 MONTE CORONA, VALENCIA - WALL BROWN BUTTERFLY (Lasiommata megera)

Lasiommata megera, the wall or wall brown, is a butterfly in the family Nymphalidae (subfamily Satyrinae). It is widespread in the Palearctic realm with a large variety of habitats and number of generations a year.

The species lives in North Africa, Europe, the Caucasus, Asia Minor, the Middle East, western Siberia, northern Tian Shan, Dzungarian Alatau, Kazakhstan and Dzungaria.

Habitats include forest edges and clearings, shrubby areas in ravines and river valleys and sparse woodlands. It is also found in mountain habitats up to 0–3,000 metres (0–9,843 ft) above sea level.

The imago flies from April to October in two or three generations depending on locality and altitude. The larva feeds on grasses in the genera Festuca, Bromus, Deschampsia, Poa, Dactylis and Brachypodium.

"The egg is pale green when first laid, and in shape it is almost spherical, but rather higher than broad; it is finely ribbed and reticulated, but unless examined through a lens it appears to be quite smooth. The caterpillar when full grown is whitish-green, dotted with white. From the larger of these dots on the back arise greyish bristles; the three lines on the back (dorsal and sub-dorsal) are whitish, edged with dark green; the line on the sides (spiracular) is white, fringed with greyish hairs; anal points green, hairy, extreme tips white. Head larger than the first ring (first thoracic segment), green dotted with white and hairy, jaws marked with brownish. The chrysalis is green, with yellow-tinted white markings on the edge of the wing covers and ridges; the spots on the body are yellowish, or sometimes white. Occasionally the chrysalids are blackish, with white or yellow points on the body". (South 1906)

28-10-2017 MONTE CORONA, VALENCIA - WALL BROWN BUTTERFLY (Lasiommata megera)

Lasiommata megera, the wall or wall brown, is a butterfly in the family Nymphalidae (subfamily Satyrinae). It is widespread in the Palearctic realm with a large variety of habitats and number of generations a year.

The species lives in North Africa, Europe, the Caucasus, Asia Minor, the Middle East, western Siberia, northern Tian Shan, Dzungarian Alatau, Kazakhstan and Dzungaria.

Habitats include forest edges and clearings, shrubby areas in ravines and river valleys and sparse woodlands. It is also found in mountain habitats up to 0–3,000 metres (0–9,843 ft) above sea level.

28-10-2017 MONTE CORONA, VALENCIA - RED ADMIRAL BUTTERFLY (Vanessa atalanta)

Vanessa atalanta, the red admiral or, previously, the red admirable, is a well-characterized, medium-sized butterfly with black wings, red bands, and white spots. It has a wingspan of about 2 inches (5 cm).[4] It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. The red admiral is widely distributed across temperate regions of North Africa, the Americas, Europe, Asia, and the Caribbean. It resides in warmer areas, but migrates north in spring and sometimes again in autumn. Typically found in moist woodlands, the red admiral caterpillar's primary host plant is the stinging nettle (Urtica dioica); it can also be found on the false nettle (Boehmeria cylindrica). The adult butterfly drinks from flowering plants like Buddleia and overripe fruit. Red admirals are territorial; females will only mate with males that hold territory. Males with superior flight abilities are more likely to successfully court females. It is known as an unusually calm butterfly, often allowing observation at a very close distance before flying away, also landing on and using humans as perches.

The Red Admiral was not named after a British naval commander, but rather by 18th-century naturalists. Its name is a corruption of the word “admirable.” 

Once fully grown, Red Admirals only live for up to six months during the summer and up to nine months during the winter.

28-10-2017 MONTE CORONA, VALENCIA - COMMON DARTER DRAGONFLY (FEMALE) (Sympetrum striolatum)

The common darter (Sympetrum striolatum) is a dragonfly of the family Libellulidae native to Eurasia. It is one of the most common dragonflies in Europe, occurring in a wide variety of water bodies, though with a preference for breeding in still water such as ponds and lakes. In the south of its range adults are on the wing all year round.

Sympetrum species are not easy to tell apart and in most areas more than one Sympetrum species will occur. Females and teneral individuals have light yellow thorax and abdomen. Males turn red as they mature. Females darken with age, becoming a dark chocolate brown, and sometimes develop a blue colouration to the bottom of the abdomen. The wings also develop a brown tinge with age. In all cases the legs have a cream or yellow stripe on a black background - this is a diagnostic feature of this species. The pterostigma of the females can be red, blue, pale blue or brown.

Adults can be seen on the wing all year round in southern Europe but in northern regions they occur from June to November.

This small dragonfly is seen in a wide variety of habitats, including lakes, ponds, canals and slow-flowing rivers. They are ambush predators, waiting on a prominent perch - such as a leaf or the top of a gate, until prey fly past, whereupon they will fly after it. They are territorial on breeding waters, often attempting to chase much bigger dragonflies away such as southern hawkers. This habit of repeatedly returning to a sunny spot allows you to easily predict where they are going to land, which is why it is one of the easiest dragonflies to photograph.

In suitable hunting areas away from water, however, they are not territorial: large numbers may assemble - groups of several hundred in a single field have been recorded - and lines of insects can be seen along the top of field gates.

Eggs are not laid, but broadcast from the air: the male holds the female in tandem and swings her down and forward over water. At the furthest point of the arc the female releases some of her eggs to fall on the water.

This is one of the most abundant dragonflies in Europe, and populations show no evidence of decline.

28-10-2017 MONTE CORONA, VALENCIA - WALL BROWN BUTTERFLY (Lasiommata megera)

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.[4] 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. The apical ocellus has a stronger tendency towardsduplication being usually somewhat distorted obliquely and — at least beneath — bearing two pupils. Between this ocellus and the apex there is nearly always a minute eye-dot, there occurring also often specimens with other accessory ocelli . Moreover, the ocelli of the hindwing are as a rule somewhat larger than in the same sex of hiera — A very large material proves that it is hardly possible to find definite trenchant distinctions , especially if one takes into account the large number of local forms of maera, all the various kinds of pattern and coloration exhibiting a great variability.

28-10-2017 MONTE CORONA, VALENCIA - COAL TIT (Periparus ater)

The Coal tit (Periparus ater) is a small passerine bird widespread and common resident breeder throughout the temperate to subtropical Palearctic, including North Africa.

The Coal tit has a distinctive large white nape spot on its black head. The head, throat, and neck of the adult are glossy blue-black, setting off the off-white sides of the face (tinged grey to yellow depending on subspecies) and the brilliant white nape; the white tips of the wing coverts appear as two wingbars. The underparts are whitish shading through buff to rufous on the flanks. The bill is black, the legs lead-colored, and the irides dark brown. The young birds are duller than the adults, lacking gloss on the black head, and with the white of nape and cheeks tinged with yellow.

Coal tits are found throughout Europe, Asia, and North Africa. They are all-year residents throughout almost all range, making only local movements in response to particularly severe weather; only the Siberian birds have a more regular migration. Coal tits prefer humid conifer forests but also frequent shrubland, conifer plantations, gardens, and urban areas.

Coal tits are social birds and often form small flocks in winter with other tits. They resemble other tits in acrobatic skill and restless activity, though they more frequently pitch on a trunk, and in little hops resemble a treecreeper. Coal tits are active during the day spending most of their time searching for food trees. They also visit gardens to feed on a variety of foods put out, particularly sunflower seeds. While searching for food, Coal tit flocks keep contact with incessant short 'dee' or 'see-see' calls. Their song is a strident 'if-he, if-he, if-he', heard most frequently from January to June, but also in autumn. The song resembles that of the Great tit, but much faster and higher in pitch. North African birds also have a 'currr' call similar to that of the European crested tit which is not found in Africa.

Coal tits are herbivores (granivores) and carnivores (insectivores). They feed on various seeds, sap, insects, and spiders.

Coal tits breed once per year between March and late July. They prefer to nest in a hole in a rotting tree stump, often low down, and the nest is deep within the hole; holes in the ground, burrows of mice or rabbits, chinks between the stones in walls, old nests of Pica magpies or other large birds, and squirrel dreys are also occupied. The materials, moss, hair, and grass, are closely felted together, and rabbit fur or feathers are added for the lining. The female lays 7 to 11 red-spotted white eggs and incubates them for 14-16 days. The chicks hatch blind and helpless and remain in the nest for about 14 to 19 days.

27-10-2017 MONTE CORONA, VALENCIA - FIRECREST (Regulus ignicapilla)

The Common Firecrest, Regulus ignicapilla, is a diminutive passerine, a member of the kinglet family. It is characterized by its vibrant olive-green upperparts, with a distinctive bronze patch on each shoulder, and its underparts are a soft whitish hue, tinged with brownish-grey on the breast and flanks. The head is adorned with a striking pattern: a black eye stripe, a long white supercilium, and a crest that is a brilliant yellow in females and a vivid orange in males.

Adult firecrests are unmistakable with their bold head pattern and bronze shoulders. The male's orange crest and the female's yellow crest are particularly prominent during the breeding season. Juveniles can be identified by their grey-tinged upperparts and less vibrant head markings. The firecrest's flight is characterized as weak and whirring, with occasional quick, evasive turns.

The Common Firecrest favors broadleaved or coniferous woodland and gardens for breeding. It shows a preference for cork oak and alder in lowland broadleaf forests, but also inhabits mixed woodlands and various coniferous trees, often with undergrowth of juniper, ivy, and wild rose.

This species is found across most of temperate Europe and northwestern Africa. It is partially migratory, with central European birds wintering to the south and west of their breeding range. The Balearic Islands and north Africa host the subspecies R. i. balearicus, while the Madeira firecrest, previously considered a subspecies, is now recognized as a distinct species.

The Common Firecrest is a restless bird, constantly on the move as it forages. It often hovers while searching for insects and is known to join flocks of tits in winter. The species is monogamous, with males displaying their crests and engaging in a unique display during the breeding season.

The firecrest's call is a series of thin, high notes, slightly lower-pitched than those of its relative, the goldcrest. Its song consists of a repetition of these call notes in a longer and slightly more varied sequence, typically lasting 0.5–2.5 seconds.

The Common Firecrest breeds in a compact, three-layered nest on a tree branch. The female incubates a clutch of 7–12 eggs, and both parents feed the chicks. The young fledge 22–24 days after hatching.

The firecrest can be distinguished from similar species like Pallas's warbler by its brighter crest and face pattern. Juvenile firecrests might be confused with goldcrests but usually show enough facial pattern to be differentiated.

Firecrests feed on small arthropods such as springtails, aphids, and spiders. They exhibit a preference for larger prey compared to goldcrests and often forage while hovering. Parents feed young chicks with smaller prey initially, gradually introducing larger items as the chicks grow.

The Common Firecrest is classified as Least Concern by the IUCN. It has a large population, estimated at 10–15 million individuals, and its range has expanded over the last century. There are no significant conservation concerns for this species at present.

26-10-2017 MONTE CORONA, VALENCIA - LACEWING (Apertochrysa flavifrons)

A very common species, mostly flying between late June and August (strongly peaking in late July/early August) but I have recorded this species right up to the second half of October.

This is one of a group of relatively unmarked green lacewings that require examination of the hairs on the wing to identify. Firstly eliminate the Chrysoperla spp. (see Chrysoperla carnea for details - and remember, best to check both wings in case of abnormalities). Also check there is no black spot between the antennae and the second segment of the antennae is green. You are then left with the Nineta species, the commonest of which, vittata, is large and has a long swollen basal segment of the antennae. The other Nineta species are usually large (forewing >= 16mm) and if you happen across an unusually small example the species so far recorded in Norfolk has a concave costal edge to the forewing.

Unlike the similar Cunctochrysa species, flavifrons lacks a strong pale creamy stripe down the centre of the thorax and the hairs on the costa stick out more prominently. Compared to Chrysopidia ciliata these hairs are more angled, lying at around 45 degrees to the costa whereas they're closer to straight out on ciliata. The hairs on the costal cross-veins mostly point backwards but a few may point forwards too, however these hairs don't generally overlap like they do in ciliata as they are shorter. The palps are ringed with black whereas if they're dark at all on ciliata it should only be on the outer face.

26-10-2017 MONTE CORONA, VALENCIA - EURASIAN SISKIN (Spinus spinus)

The Eurasian siskin (Spinus spinus) is a small passerine bird in the finch family Fringillidae. It is also called the European siskin, common siskin or just siskin. Other (archaic) names include black-headed goldfinch, barley bird and aberdevine. It is very common throughout Europe and Eurosiberia. It is found in forested areas, both coniferous and mixed woodland where it feeds on seeds of all kinds, especially of alder and conifers.

It can be distinguished from other similar finches by the colour of the plumage. The upper parts are greyish green and the under parts grey-streaked white. Its wings are black with a conspicuous yellow wing bar, and the tail is black with yellow sides. The male has a mainly yellow face and breast, with a neat black cap. Female and young birds have a greyish green head and no cap. It is a trusting, sociable and active bird. The song of this bird is a pleasant mix of twitters and trills. For these reasons it is often raised in captivity.

These birds have an unusual migration pattern as every few years in winter they migrate southwards in large numbers. The reasons for this behaviour are not known but may be related to climatic factors and above all the availability of food. In this way overwintering populations can thrive where food is abundant. This small finch is an acrobatic feeder, often hanging upside-down like a tit. It will visit garden bird feeding stations.

The siskin was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Fringilla spinus, in the 10th edition of Systema Naturae. In 1760, Brisson described the genus Carduelis, where this species was then placed. Recent taxonomic studies suggest placing it in the genus Spinus.

The scientific name Spinus is from the Ancient Greek spinos, a name for a now-unidentifiable bird. The English name is from German dialect sisschen or zeischen,

Despite being found across a wide area it is a monotypic species, that is, there are no distinct subspecies. This could be explained by a number of factors, such as spatial variability of individuals in breeding areas between years, the large overwintering area which supports a constant genetic interchange, and females having a number of clutches of eggs in one breeding season, each in a different place.

This bird may have reached America either from Asia or from Europe (Greenland/Iceland). It is the extant parental species of one of the Spinus/Carduelis three evolutive North American radiations of atriceps, pinus and dominicensis finches. It has been recorded both in the Aleutian Islands and the east: the Labrador Peninsula and St. Lawrence River mouth (Canada). This raises the possibility that this bird entered (or may still try to enter) America through Greenland/Iceland from Western Europe.

The bird's appearance shows sexual dimorphism. The male has a greyish green back; yellow rump; the sides of the tail are yellow and the end is black; the wings are black with a distinctive yellow wing stripe; its breast is yellowish becoming whiter and striped towards the cloaca; it has a black bib (or chin patch) and on its head it has two yellow auriculas and a black cap. The amount of black on the bib is very variable between males and the size of the bib has been related to dominance within a flock. The plumage of the female is more olive-coloured than the male. The cap and the auriculas are greenish with a white bib and a rump that is a slightly striped whitish yellow. The young have a similar colouration to the females, with drab colours and a more subdued plumage.

The shape of the siskin's beak is determined by its feeding habits. It is strong although it is also slender in order to pick up the seeds on which they feed. The legs and feet are dark brown and the eyes are black.

It has a rapid and bounding flight pattern that is similar to other finches.

The siskin is easy to recognize, but in some instances it can be confused with other finches such as the citril finch, the European greenfinch or the European serin. The Eurasian siskin, in many plumages, is a bright bird. Adult male Eurasian siskins are bright green and yellow with a black cap, and an unstreaked throat and breast. Adult females also usually have green and yellow plumage tones: for example, yellow in the supercilium and on the sides of the breast, green tones in the mantle and yellow in the rump. The ground colour of the underparts of the Eurasian siskin is normally pure white. In females and juveniles, the centre of the belly and lower breast are often largely or entirely unstreaked. The wingbars of the Eurasian siskin are broad and yellow (with the tips white) and the bill is short with a decurved culmen.

The siskin is a small, short-tailed bird, 11–12.5 centimetres (4.3–4.9 in) in length with a wingspan that ranges from 20 to 23 centimetres (7.9 to 9.1 in). It weighs between 12 and 18 grams (0.42 and 0.63 oz).

This species can be found across the greater part of Eurosiberia and the north of Africa. Its breeding area is separated into two zones, both on each side of the Palearctic realm: the eastern coast of Asia and the central and northern part of Europe.

These birds can be found throughout the year in Central Europe and some mountain ranges in the south of the continent. They are present in the north of Scandinavia and in Russia and they over-winter in the Mediterranean basin and the area around the Black Sea. In China they breed in the Khingan Mountains of Inner Mongolia and in Jiangsu province; they spend winter in Tibet, Taiwan, the valleys of the lower Yangtse River and the south east coast.

The Eurasian siskin is occasionally seen in North America. There is also a similar and closely related North America counterpart, the pine siskin (Spinus pinus).

Their seasonal distribution is also marked by the fact that they follow an anomalous migration pattern. Every few years they migrate southwards in larger numbers and the overwintering populations in the Iberian Peninsula are greatly augmented. This event has been the object of diverse theories, one theory suggests that it occurs in the years when Norway spruce produces abundant seeds in the centre and north of Europe, causing populations to increase. An alternative theory is that greater migration occurs when the preferred food of alder or birch seed fails. This species will form large flocks outside the breeding season, often mixed with redpolls.

It is a bird that does not remain for long in one area but which varies the areas it uses for breeding and feeding, over-wintering from one year to the next.

Its habitat is forested areas at a particular altitude on a mountain side and they have a certain predilection for humid areas. Coniferous woodland, especially spruce, is favoured for breeding. It builds its nest in a tree, laying 2–6 eggs. The British range of this once local breeder has expanded greatly due to an increase in commercial conifer plantations. The siskin also breeds in mixed woodland; while in winter they prefer stubble and crops and areas containing trees with seeds.

They are very active and restless birds. They are also very social, forming small cohesive flocks especially in autumn and winter. They are fairly trusting of humans, it being possible to observe them from a short distance. During the breeding season, however, they are much more timid, solitary and difficult to observe. For this reason there is a German legend which says that siskins guard a magic stone in their nests that makes them invisible. It is one of the few species which has been described as exhibiting "allofeeding"' behavior, this is where subordinates (of the same sex) regurgitate food for the dominant members of the group, which creates a strong cohesion in the flocks and implies a hierarchical structure within the group.

25-10-2017 - RACO DE OLLA, VALENCIA - PIED AVOCET (Recurvirostra avosetta)

The pied avocet, Recurvirostra avosetta, presents a striking silhouette with its bold black and white plumage. This large wader, belonging to the avocet and stilt family, Recurvirostridae, is adorned with a distinctive black cap and black markings on its wings and back, contrasting sharply against its otherwise white body. The species is noted for its elegant, upturned bill and elongated, bluish legs, which add to its graceful demeanor.

Adult pied avocets measure approximately 16.5–17.75 inches in length, with a wingspan stretching around 30–31.5 inches. Their long legs and upturned bills, measuring about 2.95–3.35 inches and 3–4 inches respectively, are key features for identification. Both sexes appear similar, while juveniles can be distinguished by their more greyish and sepia tones.

These birds favor shallow lakes with brackish water and exposed mudflats, which provide ideal foraging and breeding grounds.

The pied avocet breeds across temperate Europe and extends across the Palearctic to Central Asia and the Russian Far East. It is a migratory species, with most individuals wintering in Africa or southern Asia. Some, however, remain in the milder parts of their range during winter, such as southern Spain and southern England.

Pied avocets forage in shallow waters or on mudflats, often employing a unique side-to-side scything motion with their bills to capture prey. They primarily consume crustaceans and insects. During the breeding season, they nest on open ground, often forming small groups and sometimes associating with other wader species. Their nests are typically lined scrapes or mounds of vegetation, where they lay three to five eggs.

The avocet's call is a distinctive, melodious "kluit kluit," which carries far across their watery habitats.

Pied avocets establish breeding territories in shallow brackish waters, where they lay their eggs in simple ground nests. These nests may be lined with materials or placed on mounds of vegetation to protect them from flooding.

While the pied avocet's unique plumage and bill shape make it quite distinctive, it could potentially be confused with other avocet species within the genus Recurvirostra. However, its black and white coloration and habitat preferences are usually sufficient for accurate identification.

The diet of the pied avocet consists mainly of crustaceans and insects, which they adeptly capture with their specialized bill.

The IUCN Red List classifies the pied avocet as Least Concern, indicating that, at present, the species does not face any imminent threats to its survival on a global scale.

23-10-2017 - MONTE CORONA, VALENCIA - LARGE PSAMMODROMUS LIZARD (Psammodromus algirus)

The Large Psammodromus lizard is a long, slender lizard which has incredible agility and speed. Their tails are very long and slim sometimes up to twice the length of the body, it’s limbs are also long and thin allowing short burst of high speed. It’s head is slightly pointed.

The lizard’s back is a soft milk-chocolate brown colour and there are two creamy -yellow stripes running down each flank. The back legs up to the base of the tail are a soft rust-orange colour. The body scales are somewhat ‘jagged’ keeled, pointed and almost upturned on each scale end.

Their subtle colouration camouflages them in the habitats they frequent, against the soil and dried vegetation under shrubs in forests, woodland or more open scrubland. They may be seen out in the open, but generally stick fairly close to shrubs that they can hunt through and use as cover and shelter.

Psammodromus lizards are very agile and climb nimbly through shrubs and hedges, sometimes giving away their position as they rustle through dry leaves.

This species  adapts readily to a variety of habitats from sea level up to around 2600m in altitude in the warmer southern areas of their distribution range.

Their diet consists mainly of arthropods – beetles, spiders, grasshoppers and ants, they will also eat other small lizards and fruit or seeds.

Breeding begins in the spring and there may be two or rarely three clutches consisting of between 2 to 11 eggs. The incubation time can vary from one to six weeks with the young appearing from August through to October. The young are 2.5 to 3cm in body length and have the same colouration and patterns as the adults. This species may live up to 7 years, reaching their sexual maturity when they are two years old.
