29-1-2020 CREU DE LONGA, VALENCIA - WHITE WAGTAIL (Motacilla alba)
The White Wagtail (Motacilla alba) is a small, elegant passerine bird, a member of the family Motacillidae, which includes pipits and longclaws. This slender bird measures between 16.5 to 19 cm in length, with East Asian subspecies reaching up to 21 cm. It is characterized by its long, constantly wagging tail, a behavior that has become synonymous with the genus. Weighing an average of 25 g, the White Wagtail can live up to 12 years in the wild.
Adult White Wagtails exhibit a distinctive plumage with a combination of grey, black, and white. The bird's upper parts are generally grey, with a white face, belly, and breast. Males during the breeding season may show a darker back, and the species is known for its sharp, brisk call and more melodious song during courtship.
The White Wagtail is commonly found in open country, often in close proximity to human habitation and water sources. It shows a preference for bare areas which facilitate the sighting and pursuit of prey. This bird has adapted well to urban environments, utilizing paved areas such as parking lots for foraging.
This species has a vast breeding range across Europe, the Asian Palearctic, parts of North Africa, and has a presence in Alaska. It is a migratory bird, with populations moving to Africa and parts of Asia during the winter. In Great Britain and Ireland, the darker subspecies known as the Pied Wagtail is more prevalent.
The White Wagtail is known for its perpetual tail wagging, a behavior that remains somewhat enigmatic but is thought to be a signal of vigilance to predators. It is a monogamous bird that defends its breeding territory with determination.
The call of the White Wagtail is a sharp "chisick," softer than that of the Pied Wagtail. Its song is more structured and is used by males to attract females rather than to mark territory.
29-1-2020 MONTE CORONA, VALENCIA - MEDITERRANEAN SPOTTED CHAFER (Oxythyrea funesta)
Oxythyrea funesta is a phytophagous beetle species belonging to the family Cetoniidae, subfamily Cetoniinae.
Common name "white spotted rose beetle".
This beetle is present in most of Europe, in the eastern Palearctic realm, and in the Near East. It is not present in North or South America.
Larvae are up to 30 mm long, they feed on plant roots and can remain until next spring in the soil.
The adults appear early in the spring, they grow up to 8–12 millimetres (0.31–0.47 in) and can mostly be encountered from May through July. They are considered an insect pest that do not just feed on pollen, but rode the floral organs, especially damaging light in color buds and flowers.
Their colour is black, more or less bronzed. Most of the specimens show six white spots in two longitudinal rows on the pronotum and many others on the elytra. They are completely covered with white pubescence (easily visible in profile). Older specimens usually have no hairs, as they are rubbed off with time.
The larvae build pupal cells in late summer or early autumn, in which they spend up to 1 week. They then molt. The pupal cell consists of pieces of soil and roots. The stage takes 3 weeks, but very often ends around the 15th day. The adults usually do not emerge after imagining and wait until the following spring, when they become active towards late April.
This phytophagous beetle is considered a pest because it feeds not only on pollen, but also on floral organs, particularly the light-colored flowers of Rosaceae (including fruit trees, roses, strawberries and irises). When present in large numbers, they can cause damage to peach, citrus, and Actinidia (kiwi) orchards or ornamental plant crops during flowering by consuming the stamens or damaging the pistils.
The rose chafer beetle has only one predator, the hairy scolia wasp (Scolia hirta), which parasitizes it. This species of wasp is endangered, leaving the field open for the rose chafer beetle to proliferate.
There is no chemical treatment. Gardeners who wish to eliminate this insect take advantage of its preference for white flowers, on which it is highly visible, and do so manually. This operation is more effective at lower temperatures, as the beetles' flight activity is limited below 18 degrees Celsius. Above this temperature, they will be lethargic, but their activity will gradually increase with the temperature and they will be more difficult to catch. Some commercial traps are available for purchase with chemical attractants but results are not impressive as they seem to find newly opened flower blossoms more attractive.

28-1-2020 OLIVA, VALENCIA - EUROPEAN GREENFINCH (Chloris chloris)
%2020.jpg)
The European greenfinch, or simply greenfinch, is a small passerine bird belonging to the finch family Fringillidae. Exhibiting a predominantly green plumage with yellow accents on the wings and tail, the male is a vibrant sight, while the female and juveniles are more subdued with brownish tones. This bird measures approximately 15 cm in length with a wingspan ranging from 24.5 to 27.5 cm, resembling the size and shape of a house sparrow.
To identify the European greenfinch, look for its thick and conical bill, a characteristic of seed-eating birds. The male's plumage is a striking green with yellow flashes on the wings and tail, whereas the female and young birds are more muted with brownish backs. The male's display flight is akin to a butterfly, a dance to charm its mate.
The greenfinch favors woodland edges, farmland hedges, and gardens with dense vegetation for breeding. It nests in trees or bushes within these habitats.
This bird has a broad range across Europe, North Africa, and Southwest Asia. It is mainly sedentary, but some populations in the northernmost regions migrate southwards in colder months. The species has also been introduced to Australia, New Zealand, Uruguay, and Argentina.
%2021.jpg)
The greenfinch is known for its social nature, often seen in flocks outside the breeding season. It exhibits a breeding season from March to June, with fledglings emerging in early July. The species is capable of producing multiple broods annually.
The song of the greenfinch is a delightful mix of trills and twitters, interspersed with distinctive wheezes, contributing to the rich tapestry of sounds in its natural environment.
The female greenfinch constructs the nest and incubates the eggs, typically laying 4-6 eggs per clutch. Eggs are incubated for about 13-14 days, with chicks being fed an insect larva-rich diet initially, followed by a seed paste as they grow.
Greenfinches have a varied diet consisting of seeds, berries, fruits, buds, flowers, and some arthropods. They forage in trees, bushes, and on the ground, adapting to available food sources.
The IUCN lists the European greenfinch as Least Concern, indicating a stable population despite some regional declines due to disease outbreaks.
28-1-2020 OLIVA, VALENCIA - MEADOW PIPIT (Anthus pratensis)
%2020-topaz-upscale-1.4x.jpg)
The meadow pipit (Anthus pratensis) is a small passerine bird that breeds throughout much of the Palearctic, from south-eastern 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, although even here many birds move to the coast or lowlands in winter.
It is primarily a species of open habitats, either uncultivated or low-intensity agriculture, such as grassland, moorland, and heathland, but also occurs in small numbers on arable land. In winter, it also uses saltmarshes and sometimes open woodland. It is a fairly terrestrial pipit, always feeding on the ground, but using elevated perches such as shrubs, fence lines, or electric wires as vantage points to watch for predators.

26-1-2020 MONTE CORONA, VALENCIA - GREAT TIT (Parus major)
%2020.jpg)
The great tit (Parus major) is a small passerine bird, easily recognized by its black head and neck, striking white cheeks, olive upperparts, and vibrant yellow underparts. This bird is the most widespread species in the genus Parus, found across Europe, the Middle East, Central Asia, and parts of North Africa.
Males are characterized by their bright plumage, with a black bib that extends down the belly, bordered by a lemon-yellow breast. Females and juveniles are similar but have duller coloration. The black line down the belly is also narrower and sometimes broken in these birds.
Great tits favor a variety of woodland habitats, including deciduous and mixed forests, forest edges, and even urban parks and gardens. They are also found in riverine woodlands and, in some regions, boreal taiga.
%2021.jpg)
This species is resident throughout its range, which extends from the Iberian Peninsula to the Amur Valley, and from Scandinavia to the Middle East. It is generally non-migratory, except in harsh winters when it may move to more temperate areas.
Great tits are known for their intelligence and adaptability. They exhibit a range of foraging behaviors and can solve problems with insight learning. They are also cavity nesters and are monogamous, with both parents involved in raising the chicks.
The great tit has a repertoire of up to 40 calls and songs, with the male being particularly vocal. A common call resembles the phrase "teacher, teacher," which is used to proclaim territory.
Breeding occurs once a year, with the female laying up to 12 eggs in a cavity nest. The female incubates the eggs alone, but both parents feed the chicks. In most years, the pair will raise two broods.
In summer, the diet is predominantly insectivorous, while in winter, it expands to include seeds and berries. Great tits are adept at handling large food items and are known to visit bird feeders in urban areas.

29-11-2019 SUECA, VALENCIA - MEADOW PIPIT (Anthus pratensis)
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.
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.
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.
%2020.jpg)
It is primarily a species of open habitats, either uncultivated or low-intensity agriculture, such as pasture, bogs, and moorland, but also occurs in low numbers in arable croplands. In winter, it also uses saltmarshes and sometimes open woodlands. It is a fairly terrestrial pipit, always feeding on the ground, but uses elevated perches such as shrubs, fence lines, or electricity wires as vantage points to watch for predators.
The estimated total population is 12 million pairs. It is an abundant species in the north of its range, and generally the commonest breeding bird in most of upland Britain, but less common further south. Breeding densities range from 80 pairs/km2 (210 pairs/sq mi) in northern Scandinavia, to 5–20 pairs/km2 (13–52 pairs/sq mi) in grassland in the south of the breeding range, and just 1/km2 (2.6/sq mi) in arable farmland. A few isolated breeding pairs are recorded from south of the main range, in the mountains of Spain, Italy, and the northern Balkans. A general decline in the population has occurred over the past 17 years, most notable in French farmland, with a 68% drop.
23-1-2020 TANCAT DE L'ILLA, VALENCIA - COMMON SANDPIPER (Actitis hypoleucos)
%2020.jpg)
The Common Sandpiper, Actitis hypoleucos, is a small wader of the Palearctic region, easily recognized by its greyish-brown upperparts and pristine white underparts. Adults typically measure between 18-20 cm in length, with a wingspan of 32-35 cm. They possess short, dark-yellowish legs and feet, and a bill that is pale at the base with a dark tip.
In the field, look for the Common Sandpiper's distinctive stiff-winged flight pattern, just above the water's surface. During the non-breeding season, they appear duller and exhibit more noticeable barring on the wings, which is most visible at close range. Juveniles display heavier barring above and buff edges to their wing feathers. The species can be differentiated from the similar Spotted Sandpiper by its darker legs and feet and the crisper wing pattern, especially in flight.
These birds are often found near freshwater sources, where they nest on the ground in close proximity to the water's edge.
23-1-2020 TANCAT DE L'ILLA, VALENCIA - WESTERN SWAMPHEN (Porphyrio porphyrio)
The Western Swamphen, Porphyrio porphyrio, is a striking waterbird of the rail family Rallidae. Known also as the sultana bird, this species is adorned with vibrant plumage, large feet, and a distinctive red bill and frontal shield, making it a conspicuous presence in its natural habitat.
This chicken-sized bird can be identified by its bright plumage, which is typically purple-blue, and its red bill and frontal shield. The large feet of the Western Swamphen are another characteristic feature, aiding in its navigation through wetland vegetation.
The Western Swamphen is found in a variety of wetlands, including swamps, lake edges, and damp pastures. These environments provide the bird with the necessary resources for feeding and breeding.

The Western Swamphen is found in a variety of wetlands, including swamps, lake edges, and damp pastures. These environments provide the bird with the necessary resources for feeding and breeding.
The species is native to parts of the Western Palearctic, with populations in Spain, Portugal, southeastern France, Italy (notably Sardinia and Sicily), and northwestern Africa, including Morocco, Algeria, and Tunisia.
Despite its somewhat clumsy flight, the Western Swamphen is capable of flying long distances. It is also an adept swimmer, particularly for a bird without webbed feet. The species is known for its loud, quick calls, which include bleating and hooting sounds that are quite unbird-like in tone. These calls are especially prevalent during the breeding season.
The Western Swamphen's vocalizations are distinctive and varied, including loud and quick bleating and hooting calls. These sounds are an integral part of the bird's social and breeding behaviors.
Breeding typically occurs seasonally, with timing correlating with peak rainfall or summer in temperate regions. The Western Swamphen nests in warm reed beds, constructing large pads of interwoven reeds on floating debris or just above water level. Both sexes incubate the 3–6 speckled eggs for 23–27 days. Chicks are precocious, feathered with downy black plumage, and are able to leave the nest shortly after hatching, though they may remain for a few days before venturing out.
The diet of the Western Swamphen includes tender shoots and vegetable-like matter found within its wetland habitat. It also consumes eggs, ducklings, small fish, and invertebrates such as snails. There are reports of these birds attacking large eels, though it is not confirmed if eels are a regular part of their diet. They are known to use one foot to bring food to their mouth rather than eating it on the ground.
The Western Swamphen is currently classified as Least Concern by the IUCN. The species has experienced a recovery in numbers following conservation efforts, including habitat protection and reintroduction schemes. It was once listed as "Rare" by the European Union but has since been reclassified as "Localised". The largest population resides in Spain, where the species has shown significant population growth and range expansion.
23-1-2020 MONTANYETA DEL SANS, VALENCIA - LITTLE EGRET (Egretta garzetta)
The Little Egret, Egretta garzetta, is a dainty heron adorned in pure white plumage. It is characterized by a slender black beak, long black legs, and, notably in the western race, yellow feet. This elegant bird is a sight to behold with its graceful neck and poised stance.
Adult Little Egrets measure between 55–65 cm in length with a wingspan of 88–106 cm, and weigh 350–550 g. Their plumage is predominantly white, though some may exhibit bluish-grey coloration. Breeding adults boast ornate nape plumes reaching about 150 mm, along with distinctive feathers on the breast and elongated scapulars. The bill and lores are black, with greenish-grey skin at the base of the lower mandible and around the eye, which houses a yellow iris. Legs are black with contrasting yellow feet, though juveniles may have greenish-black legs and duller feet. The subspecies E. g. nigripes is distinguished by yellow skin between the bill and eye, and blackish feet.
The Little Egret frequents a variety of wetland habitats, from the shores of lakes and rivers to marshes and coastal regions. It is often found in open environments, such as mangroves, swamps, mudflats, and sandy beaches, as well as human-altered landscapes like rice fields.
23-1-2020 SUECA, VALENCIA - CATTLE EGRET (Bubulcus ibis)
The western cattle egret (Bubulcus ibis) is a species of heron (family Ardeidae) found in the tropics, subtropics and warm temperate zones. Most taxonomic authorities lump this species and the eastern cattle egret together (called the cattle egret), but some (including the International Ornithologists' Union) separate them. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century.
It is a white bird adorned with buff plumes in the breeding season. It nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Western cattle egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inundated grasslands, pastures, farmlands, wetlands and rice paddies. They often accompany cattle or other large mammals, catching insect and small vertebrate prey disturbed by these animals. Some populations of the cattle egret are migratory and others show post-breeding dispersal.

22-1-2020 MONTE CORONA, VALENCIA - EUROPEAN ROBIN (Erithacus rubecula)
%2020.jpg)
European robins occur in Eurasia east to Western Siberia, south to Algeria, and on the Atlantic islands as far west as the Central Group of the Azores and Madeira. Irish and British robins are largely resident but a small minority, usually female, migrate to southern Europe during winter, a few as far as Spain. Scandinavian and Russian robins migrate to Britain and western Europe to escape the harsher winters. European robins prefer spruce woods in northern Europe, contrasting with their preference for parks and gardens in Ireland and Great Britain. These may also be found in grasslands, shrubby vegetation, hedgerows with some tall trees, orchards, and farmlands.
European robins are active during the day, however, they may also hunt insects on moonlit nights or near artificial light at night. These are generally solitary and territorial birds, and males are noted for their highly aggressive territorial behavior. They will fiercely attack other males and competitors that stray into their territories and may even attack other small birds without apparent provocation.
%2021.jpg)
European robins communicate using a variety of calls, including a ticking note that usually indicates anxiety or mild alarm. During the breeding season, robins produce a fluting, warbling song. Both the male and female sing during the winter, when they hold separate territories; the song then sounds more plaintive than the summer version.
The female typically moves a short distance from the summer nesting territory to a nearby area that is more suitable for winter feeding. The male keeps the same territory throughout the year. During the breeding season, males usually initiate their morning song an hour before civil sunrise and usually terminate their daily singing around thirty minutes after sunset. They may also sing at night, especially in urban areas that are artificially lit during the night.
22-1-2020 MONTE CORONA, VALENCIA - EGYPTIAN BIRD GRASSHOPPER (Anacridium aegyptium)
%2020.jpg)
Anacridium aegyptium, the Egyptian grasshopper or Egyptian locust, is a species of insect belonging to the subfamily Cyrtacanthacridinae.
A fairly common species, the Egyptian grasshopper is present in most of Europe, the Afrotropical realm, eastern Palearctic realm, the Near East, and North Africa, and has recently been observed in Cape Town, South Africa.
These grasshoppers inhabit trees and shrubs, scrub land, maquis, and orchards in warm and bright environments, at an elevation from sea level to 1,500 m.
Anacridium aegyptium is one of the largest European grasshoppers. Adult males grow up to 30–56 mm (1.2–2.2 in) long, while females reach 46–70 mm (1.8–2.8 in) in length. Their bodies are usually gray, brown, or olive-coloured, and their antennae are relatively short and robust. The tibiae of the hind legs are blue, while the femora are orange. The hind femora have characteristic dark marks. They are also easily identified by their characteristic eyes, which have vertical black and white stripes. Their pronota show a dorsal orange stripe and several small white spots. The wings are clear with dark marks.
This species is a folivore, essentially feeding on leaves of various plants. It is a solitary species, harmless to crops. Adults are mainly seen in August and September, but they are active throughout the year. After mating, these grasshoppers overwinter as adults. Spawning occurs in spring just under the soil surface and the nymphs appear in April. These grasshoppers undergo several molts. Nymphs differ from adults in appearance; their color varies from yellow to bright green and ocher and the wings are absent or small, as they are gradually developed after each molt.
