5-12-2018 PUCOL, VALENCIA - EURASIAN GREEN WINGED TEAL (Anas crecca)
%2020.jpg)
The Eurasian teal (Anas crecca), common teal, or Eurasian green-winged teal is a common and widespread duck that breeds in temperate Eurosiberia and migrates south in winter. The Eurasian teal is often called simply the teal due to being the only one of these small dabbling ducks in much of its range. The bird gives its name to the blue-green colour teal.
It is a highly gregarious duck outside the breeding season and can form large flocks. It is commonly found in sheltered wetlands and feeds on seeds and aquatic invertebrates. The North American green-winged teal (A. carolinensis) was formerly (and sometimes is still) considered a subspecies of A. crecca.

The Eurasian teal belongs to the "true" teals, a group of small Anas dabbling ducks closely related to the mallard (A. platyrhynchos) and its relatives; that latter group in fact seems to have evolved from a true teal. It forms a superspecies with the green-winged teal and the speckled teal (A. flavirostris). A proposed subspecies, A. c. nimia of the Aleutian Islands, differs only in slightly larger size; it is probably not distinct.
Whether the Eurasian and green-winged teals are to be treated as one or two species is still being reviewed by the American Ornithologists' Union, while the International Union for Conservation of Nature and BirdLife International separate them nowadays. Despite the almost identical and highly apomorphic nuptial plumage of their males, which continues to puzzle scientists, they seem well distinct species, as indicated by a wealth of behavioural, morphological, and molecular data.

5-12-2018 PUCOL, VALENCIA - MONK PARAKEET (Myiopsitta monachus)
The Monk Parakeet, also known as the Quaker Parrot, is a small and vibrant green parrot with a greyish breast and a greenish-yellow abdomen. This charming bird is a member of the true parrot family, Psittacidae, and is known for its relatively long lifespan of 20-30 years.
Adult Monk Parakeets measure approximately 29 cm (11 in) in length with a wingspan of 48 cm (19 in), and an average weight of 100 g (3.5 oz). The species exhibits sexual dimorphism, with females being 10-20% smaller than males. They possess bright-green upperparts, a pale gray forehead and breast with darker scalloping, and very light-green to yellow underparts. Their remiges are dark blue, and they have a long, tapering tail. The bill is a notable orange color. Vocalizations include a loud and throaty chape(-yee) or quak quaki quak-wi quarr, and screeches skveet.
Monk Parakeets are adaptable birds that originally inhabit temperate to subtropical areas of South America. They are known to build stick nests in trees or on man-made structures, a unique behavior among parrots.
Native to South America, these birds are common in Argentina, Brazil, and Uruguay. They have established feral populations in North America and Europe, mainly in urban areas and regions with climates similar to their native habitat.
Monk Parakeets are gregarious and often breed colonially. They construct large communal nests with separate entrances for each pair. These nests can become quite sizable and may house other species. The birds are known to have helper individuals that assist with feeding the young, a behavior known as kin selection.
The Monk Parakeet's call is a distinctive and throaty chape(-yee) or quak quaki quak-wi quarr, with screeches of skveet. These vocalizations are important for communication within the species.
These parakeets breed in colonies, with nests that can house multiple pairs. Each pair has its own entrance to the communal nest. They lay five to 12 white eggs, which hatch in about 24 days.
The Cliff Parakeet (Myiopsitta luchsi) is similar in appearance but is considered a separate species due to morphological, behavioral, and geographical differences.
Monk Parakeets are known to feed on various seeds, fruits, and vegetation. In their native range, they are sometimes considered agricultural pests due to their feeding habits.
The Monk Parakeet is currently listed as Least Concern on the IUCN Red List. However, in some introduced areas, they are subject to control measures due to concerns about their impact on local ecosystems and agriculture.

4-12-2018 EL VERHEL, ALICANTE - MEADOW PIPIT (Anthus pratensis)
%2021.jpg)
The meadow pipit (Anthus pratensis) is a small passerine bird, which breeds in much of the Palearctic, from southeastern Greenland and Iceland east to just east of the Ural Mountains in Russia, and south to central France and Romania; an isolated population also occurs in the Caucasus Mountains. It is migratory over most of its range, wintering in southern Europe, North Africa, and south-western Asia, but is resident year-round in western Europe, though even here many birds move to the coast or lowlands in winter.
%2022.jpg)
This is a widespread and often abundant small pipit, 14.5–15 cm (5+1⁄2–6 in) long and 15–22 g (0.53–0.78 oz) weight. It is an undistinguished-looking species on the ground, mainly brown above and buff below, with darker streaking on most of its plumage; the tail is brown, with narrow white side edges. It has a thin bill and pale pinkish-yellow legs; the hind claw is notably long, longer than the rest of the hind toes. The call is a weak tsi-tsi. The simple repetitive song is given in a short song flight. Birds breeding in Ireland and western Scotland are slightly darker coloured than those in other areas, and are often distinguished as the subspecies A. p. whistleri, though it intergrades clinally with nominate A. p. pratensis found in the rest of the species' range.
It is similar to the red-throated pipit A. cervinus, which is more heavily streaked and (in summer only) has an orange-red throat, and to the tree pipit A. trivialis, which is slightly larger, less heavily streaked, and has stronger facial markings and a shorter hind claw. The song of the meadow pipit accelerates towards the end while that of the tree pipit slows down.
4-12-2018 MARXUQUERA, VALENCIA - BLACK REDSTART (FEMALE) (Phoenicurus ochruros)
%20(Phoenicurus%20ochruros)%2020.jpg)
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.

2-12-2018 ADOR CAMPO, VALENCIA - MEADOW PIPIT (Anthus pratensis)
%2020.jpg)
The Meadow Pipit, Anthus pratensis, is a small, unassuming bird of the
passerine family. It measures between 14.5 to 15 cm in length and weighs a mere 15 to 22 grams. Its plumage is predominantly brown above and buff below, with darker streaks adorning most of its body. The tail is brown with narrow white edges, and it stands on pale pinkish-yellow legs. A distinctive feature is its notably long hind claw, surpassing the length of its other hind toes.
When identifying the Meadow Pipit, look for its streaked appearance and listen for its weak "tsi-tsi" call. In flight, observe its song, which is a simple, repetitive tune that increases in pace towards the end. The bird's small size and long hind claw are also key identification markers.
%2021.jpg)
The Meadow Pipit favors open spaces such as pastures, bogs, and moorlands. It can also be found in low-intensity agricultural areas and, during winter, in saltmarshes and occasionally open woodlands.
This species breeds across the Palearctic, from Greenland and Iceland to the Ural Mountains, and south to central France and Romania. An isolated population resides in the Caucasus Mountains. While migratory over most of its range, wintering in southern Europe, North Africa, and southwestern Asia, it remains resident year-round in western Europe.

27-3-2018 FERNKLOOF LAKE, SOUTH AFRICA - THREE BANDED PLOVER (Charadrias tricollaris)
The Three-banded Plover, or Charadrius tricollaris, is a small wader, measuring 18 cm in length, with a distinctive elongated profile characterized by its long wings and very long tail. This bird is easily recognized in flight by its white front and the white side of the tail and rump. The adult's upperparts are a medium brown, while the underparts are predominantly white, featuring two black breast bands separated by a white band, which are the hallmark of this species. The head boasts a striking pattern with a black crown and white supercilia extending from the white forehead to meet at the back of the neck. The face is grey, transitioning to brown on the neck, and the orbital ring is a vivid orange-red. The bill is mostly black with a rosy red base.
When identifying the Three-banded Plover, look for the unique combination of the two black breast bands and the white band in between. The long wings and tail are also key features, setting it apart from most other small plovers. The thin white bar above the wings and the dark smudge over the primary coverts below are visible in flight. The Malagasy subspecies can be distinguished by a grey band between the bill and the white forehead, and grey sides of the head.
This species is typically found along inland rivers, pools, lakes, and pans, where it frequents exposed shores.
The Three-banded Plover is resident and generally sedentary across much of East Africa, southern Africa, and Madagascar.
Often seen as solitary individuals, the Three-banded Plover may also gather in small flocks. It hunts primarily by sight, searching for insects, worms, and other invertebrates.
The call of the Three-banded Plover is a sharp, whistled "weeet-weet."
Breeding involves a simple nest, which is a bare scrape on shingle. Egg laying varies by region, occurring from March to June in the tropics, but predominantly from July to October in southern Africa.
The diet consists of insects, worms, and other small invertebrates, which the Three-banded Plover hunts by sight.

29-11-2018 MONTE CORONA, VALENCIA - PUG MOTH (Genus Eupithecia)
%2020.jpg)
Eupithecia is the largest genus of moths of the family Geometridae, and the namesake and type genus of tribe Eupitheciini. Species in the genus are, like those of other genera in the tribe, commonly known as pugs. The genus is highly speciose, with over 1400 species, and members of the genus are present in most of the world with exception of Australasia. Roughly a quarter of described Eupithecia species occur in the Neotropical realm, where they have an especially high species diversity in the montane rain forests of the Andes. The genus includes a few agricultural pest species, such as the currant pug moth, Eupithecia assimilata, which is a pest on hops, and the cloaked pug moth, Eupithecia abietaria, which is a cone pest in spruce seed orchards.
Adult specimens of Eupithecia are typically small, often between 12 and 35 mm, with muted colours, and display a large amount of uniformity between species. As a result, identification of a specimen as part of genus Eupithecia is generally easy, but identifying the exact species is difficult and often reliant on examination of the dissected genitals. Most species share a characteristic resting pose in which the forewings are held flat at a right angle to the body—that is, the costal margins of both forewings form a more-or-less horizontal line—while the hindwings are largely covered by the forewings. They are generally nocturnal.
