17-2-2021 RACO DE OLLA, 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.


The average wingspan of both males and females is 5.1 cm (2 in), although males tend to be slightly smaller than females. Furthermore, males possess a row of grayish-brown scent scales on their forewings that is absent in the females. Females have brighter and more distinct markings than males. The subspecies P. a. tircis is brown with pale yellow or cream spots and darker upperwing eyespots. The subspecies P. a. aegeria has a more orange background and the hindwing underside eyespots are reddish brown rather than black or dark gray. 

The two forms gradually intergrade into each other. Subspecies P. a. oblita is a darker brown, often approaching black with white rather than cream spots. The underside of its hindwings has a marginal pale purple band and a row of conspicuous white spots. The spots of subspecies P. a. insula are a tawny orange rather than a cream color. The underside of the forewings has patches of pale orange, and the underside of the hindwing has a purple-tinged band. Although there is considerable variation with each subspecies, identification of the different subspecies is manageable.

17-2-2021 CREU DE LONGA, VALENCIA - LITTLE EGRET (Egretta garzetta)


The Little egret (Egretta garzetta) is small elegant heron in the family Ardeidae. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. At one time common in Western Europe, the Little heron 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.
The plumage of the Little egret is normally entirely white, although there are dark forms with largely bluish-grey plumage. In the breeding season, the adult has two long plumes on the nape that form a crest. These plumes are about 150 mm (6 in) and are pointed and very narrow. There are similar feathers on the breast, but the barbs are more widely spread. 


There are also several elongated scapular feathers that have long loose barbs and may be 200 mm (8 in) long. During the winter the plumage is similar but the scapulars are shorter and more normal in appearance. The bill is long and slender and it and the lores are black. There is an area of greenish-grey bare skin at the base of the lower mandible and around the eye which has a yellow iris. The legs are black and the feet yellow. Juveniles are similar to non-breeding adults but have greenish-black legs and duller yellow feet, and may have a certain proportion of greyish or brownish feathers. The subspecies nigripes differs in having yellow skin between the bill and eye, and blackish feet. During the height of courtship, the lores turn red and the feet of the yellow-footed races turn red.

15-2-2021 JALON, VALENCIA - DOMESTIC MALLARD (Anas platyrhynchos var. domesticus)




 

15-2-2021 JALON, VALENCIA - 15-2-2021 JALON, VALENCIA - MALLARD X MUSKOVY DUCK (Anas platyrhynchos × cairina moschata)


The cross between a Mallard (Anas platyrhynchos) and a Muscovy Duck (Cairina moschata) produces a unique hybrid often called a Mulard or Mule Duck. Because these two species belong to different genera, their offspring are almost always sterile, meaning they cannot reproduce.Quick Comparison & Hybrid Types

Mule Duck: Produced when the father is a Muscovy and the mother is a Mallard (or Mallard-derived breed like a Pekin). These are typically larger and used in the commercial meat industry.

Hinny: Produced when the father is a Mallard and the mother is a Muscovy. These are less common and generally smaller than Mule Ducks.


Key Facts & CharacteristicsAppearance: 

Hybrids often exhibit a "mixed" look. They may have the iridescent green sheen of a Mallard head but with the larger body and slight red or black caruncles (fleshy growths) around the bill typical of a Muscovy.

Voice: They are generally quieter than Mallards. While female Mallards are famous for their loud quack, these hybrids may only produce soft hisses, trills, or muffled quacks.


Behavior: They often display a blend of habits. They may prefer terrestrial foraging like a Muscovy but are also capable swimmers like a Mallard.

Commercial Use: In agriculture, Mulards are highly valued for their meat and foie gras production. They are considered hardier and grow faster than many purebred ducks.

Commonality: While rare in the wild, they are frequently seen in urban parks and lakes where domestic ducks of both species are often abandoned and interbreed.

15-2-2021 JALON, VALENCIA - BLACK REDSTART (MALE) (Phoenicurus ochruros)


The Black Redstart (Phoenicurus ochruros) is a small, charismatic passerine bird, exhibiting a blend of dark and vibrant plumage. Males are distinguished by their dark grey to black upperparts and breast, with a striking orange-red rump and tail. Females and juveniles are more subdued in color, with grey to grey-brown feathers and the same vivid tail coloration that is the hallmark of the species.

Adult males are easily identified by their dark upperparts and black breast, contrasting with the orange-red lower rump and tail. The belly and undertail may vary from blackish-grey to orange-red, depending on the subspecies. Females and juveniles are less conspicuous, with overall greyer tones and a distinctive orange-red rump and tail. The presence of pale fringes on the secondaries forms a whitish wing panel in some subspecies.

The Black Redstart has adapted remarkably to urban environments, often found nesting in crevices or holes within buildings. Originally a dweller of stony mountainous regions, it now thrives in industrial areas with similar structural features.

This species is widely distributed across south and central Europe, Asia, and north-west Africa. It is a resident in milder regions, while populations in the northeast migrate to warmer areas during winter.

The Black Redstart is known for its robin-like movements, including quick ducks of the head and body, and frequent tail flicking. Males possess a rattling song and a tick call, adding to their distinctive presence.

The Black Redstart's vocal repertoire includes a variety of calls, which differ among subspecies. The male's song is a rattling melody, while its call is a sharp 'tick', often heard during its active foraging.

Typically monogamous, the Black Redstart begins breeding in mid-April. Nests are built by females in sheltered nooks, lined with soft materials. Clutches consist of 4 to 6 eggs, incubated primarily by the female. Both parents tend to the fledglings, which leave the nest after 12 to 19 days.

The Black Redstart's diet includes insects, which it often catches mid-flight. It is also known to forage in coastal areas for tiny crustaceans and flies.

13-2-2021 ADOR CAMPO, VALENCIA - EUROPEAN SERIN (MALE) (Serinus serinus)


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.

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.

12-2-2021 MONTE CORONA, VALENCIA - PINE BEAUTY MOTH (Panolis flammea)


The pine beauty (Panolis flammea) is a moth of the family Noctuidae. It is a common species of pine woods in Europe. The distribution area extends from Portugal to western Siberia, the Caucasus and Asia Minor. In the north it extends to the Arctic Circle, in the south it is found in Ceuta in Northern Africa in and southern Italy (including Sicily and Sardinia).

The forewings are typically rich orange brown, but sometimes are dark grey, with two large pale stigmata and fine streaks along the termen. The hindwings are brown or blackish.


The wingspan is 32–40 mm. Forewing orange rufous with some ochreous admixture; the veins dotted grey and white; the inner and outer lines deeper rufous, conversely edged with white, and dentate lunulate; submarginal line pale, preceded by a dentate rufous shade; the terminal area often paler; stigmata large, irregular; the claviform with some pale and brown scales at its extremity; orbicular and reniform pale rufous with deeper centres, the orbicular flattened, its lower edge often produced along median vein as a streak and connected with reniform, which is large with the upper end angularly produced outwards; fringe mottled rufous and white hindwing fuscous, often with a reddish tinge; the ab. griseovariegata Goeze has the rufous tints obscured by glaucous grey and fuscous.

This moth flies at night from March to May  and is attracted to light and sallow blossom.

Larva bright green with the lines broadly white edged with deep green; spiracular line edged below with yellow. It feeds on the needles of Pinus sylvestris and other pines, but sometimes on other trees (see list below), and can be a serious pest in forests. The species overwinters as a pupa.

11-2-2021 POTRIES, VALENCIA - SARDINIAN WARBLER (MALE) (Sylvia melanocephala)


The Sardinian warbler (Curruca melanocephala) is a common and widespread Sylviidae warbler from the Mediterranean region. Like most Curruca species, it has distinct male and female plumages. The adult male has a grey back, whitish underparts, black head, white throat and red eyes. Plumages are somewhat variable even in the same locality, with the intensity of a reddish hue on upper- and/or underside that varies from absent to (in some subspecies) pronounced. The female is mainly brown above and buff below, with a grey head. The Sardinian warbler's song is fast and rattling, and is very characteristic of the Mediterranean areas where this bird breeds.
