27-9-2018 OLIVA MARJAL, VALENCIA - CRIMSON SPECKLED FLUNKEY MOTH (Utetheisa pulchella)

Utetheisa pulchella, the crimson-speckled flunkey, crimson-speckled footman, or crimson-speckled moth, is a moth of the family Erebidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.

This common widespread species can be found in most of Europe (as a migrant), in the entire Afrotropical realm, North Africa, in the Near East and Central Asia, in the western Indomalayan realm (not known east of Myanmar.) In the United Kingdom it is only a sporadic migrant. These moths inhabit dry open places, meadows, shrublands, grasslands and parks.

The wingspan of Utetheisa pulchella can reach 29–42 mm. The front wings are narrow, white or cream coloured with a variable pattern of numerous small black spots located between the larger-sized bright red spots. Sometimes the red spots are merged to transversal bands. The hindwings are wide, white, with an irregular black border along the outer edge and two black markings in the middle of the cell. The head and thorax range from cream colour to buff yellow, with the same pattern as the wings. The antennae are long and monofiliform. The abdomen is smooth, with a white background.

Caterpillars are warty, dark brown or greyish, with tufts of greyish hairs, an orange crossline on each segment, a wide whitish line along the back and two other lateral white lines.

27-9-2018 OLIVA MARJAL, VALENCIA - WILLOW WARBLER (Phylloscopus trochilus)

The willow warbler, Phylloscopus trochilus, presents itself as a rather unassuming yet charming leaf warbler. This small passerine measures between 11–12.5 cm in length and tips the scales at a delicate 7–15 g. Its plumage is a subtle greenish brown above, while below, it ranges from off-white to a gentle yellowish hue. The wings are a consistent greenish-brown, devoid of any wingbars, contributing to its understated elegance.

Distinguishing the willow warbler from its congeners, particularly the chiffchaff, can be a delightful challenge. Look for its paler pinkish-yellow legs, a contrast to the chiffchaff's darker limbs. The willow warbler's bill is longer and paler, and its overall shape is more refined. The primary projection, or wingtip, is notably longer, aiding in its identification. Juveniles tend to be more yellow below than their adult counterparts.

The willow warbler favors open woodlands replete with trees and ground cover suitable for nesting. It shows a particular fondness for birch, alder, and willow habitats. The proximity to the ground is crucial for its nesting sites, often chosen within low vegetation.

A true voyager, the willow warbler breeds across northern and temperate Europe and the Palearctic, stretching from Ireland to the Anadyr River basin in eastern Siberia. Come winter, the species migrates en masse to the warmer climes of sub-Saharan Africa.

The willow warbler is a highly migratory species, embarking on seasonal journeys that are remarkable for a bird of its size. It is one of the earliest warblers to herald the arrival of spring in northern Europe, though it lags slightly behind the chiffchaff. The breeding season typically yields one brood, with a rare second on occasion.

The willow warbler's song is a simple, melodious descending whistle, evoking the essence of spring. Its contact call is a distinctive disyllabic 'hoo-eet', which can be used to differentiate it from the more monosyllabic 'hweet' of the chiffchaff.

Nesting close to the ground, often in low vegetation, the willow warbler's breeding habits are a testament to its connection with the earth. The breeding season spans from late April to August, with the birds usually producing a single brood.

The chiffchaff is the willow warbler's closest look-alike, but careful observation of leg color, bill length, body shape, and primary projection can help keen birdwatchers tell them apart.

Insectivorous by nature, the willow warbler partakes in a diet consisting primarily of insects, which it deftly plucks from leaves and branches in its woodland home.

23-9-2018 MONTE CORONA, VALENCIA - MOORISH GECKO (Tarentola mauritanica)

Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas (in Montevideo, Buenos Aires and California). A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter. A robust species, up to 15 centimetres (5.9 in) long, its tubercules are enlarged and give the species a spiny armoured appearance.

The species was first described by Carl Linnaeus in 1758. It is also known as moorish gecko, crocodile gecko, European common gecko, and, regionally, as osga (in Portuguese), salamanquesa (in Spanish) and dragó (in Catalan).

20-9-2018 PARADOR ALMAGRO, LA MANCHA - EUROPEAN PIED FLYCATCHER (Ficedula hypoleuca)

The European pied flycatcher, Ficedula hypoleuca, is a diminutive passerine, a member of the Old World flycatcher family. This bird is characterized by its contrasting plumage, with males donning a striking black and white during the breeding season, while females and juveniles exhibit a more subdued brown and white. The species is known for its agility in the air as it pursues its insect prey.

Breeding males are predominantly black above with a white underbelly. Notable features include a large white patch on the wings, white sides on the tail, and a small patch on the forehead. The Iberian subspecies, iberiae, is distinguished by a larger forehead patch and a pale rump. Outside of the breeding season, males, females, and juveniles are more challenging to identify, with black replaced by pale brown, and can be easily confused with other Ficedula species.

These birds are denizens of deciduous woodlands, parks, and gardens, showing a preference for oak trees. They are adept at utilizing tree holes for nesting and can adapt to open-fronted nest boxes provided by conservation efforts.

The European pied flycatcher boasts a broad range, extending across Europe and the Western Palearctic. It is a migratory species, wintering in tropical Africa. Subspecies are distributed across various regions, from the UK and Scandinavia to the Iberian Peninsula and Russia.

The species exhibits a mixed mating system of monogamy and polygyny, with males often seeking a second mate after the primary female lays eggs. Males may assist with child-rearing duties for the primary mate, and occasionally for the secondary mate if proximity allows.

The male's song is a distinctive feature of oak woodlands in spring, described as loud, rhythmic, and melodious. It serves as a beacon during the breeding season, attracting mates and asserting territory.

Breeding takes place from June to August, with the species producing one brood per season. Nesting occurs in tree holes, and clutch size can range from 4 to 10 eggs.

The Atlas pied flycatcher, found in the mountains of northwest Africa, was once considered a subspecies but is now classified separately. The collared flycatcher is a similar species with which the European pied flycatcher may hybridize to a limited extent.

Insectivorous by nature, the European pied flycatcher's diet includes a variety of arthropods, with a particular fondness for ants, bees, and beetles. It captures its prey both in flight and from foliage.

The species is currently listed as Least Concern by the IUCN, thanks to its extensive range and population size. However, there have been noted declines in certain regions, attributed to factors such as climate change and habitat loss.

The European pied flycatcher spends the non-breeding season in sub-Saharan Africa, migrating to breeding grounds in Europe from mid-April to late May. After the breeding season, from August to mid-September, it returns to Africa.

The species thrives in upland broadleaf woodlands, particularly mature oak forests. Conservation efforts include managing grazing to maintain an open understory and providing nest boxes to compensate for the loss of natural tree holes. Grant funding for conservation is available through schemes like England's Woodland Improvement Grant and Natural England's Environmental Stewardship Scheme.

20-9-2018 ALARCOS, LA MANCHA - EUROPEAN FIREBUG (Pyrrhocoris apterus)

The firebug, Pyrrhocoris apterus, is a common insect of the family Pyrrhocoridae. Easily recognizable due to its striking red and black coloration, it may be confused with the similarly coloured though unrelated Corizus hyoscyami (cinnamon bug or squash bug). Pyrrhocoris apterus is distributed throughout the Palaearctic from the Atlantic coast of Europe to northwest China. It has also been reported from the United States, Central America, and India, and is also found in Australia. It has been reported as recently expanding its distribution northwards into mainland United Kingdom and eastward on to the coast of the Mediterranean Sea. They are frequently observed to form aggregations, especially as immature forms, containing from tens to perhaps a hundred individuals.

Firebugs generally mate in April and May. Their diet consists primarily of seeds from lime trees and mallows (see below). They can often be found in groups near the base of lime tree trunks, on the sunny side.

They can be seen in tandem formation when mating which can take from 12 hours up to 7 days. The long period of copulating is probably used by the males as a form of ejaculate-guarding under high competition with other males.

18-9-2018 TABLAS DE DAIMIEL, LA MANCHA - COMMON SHELDUCK (MALE) (Tadorna tadorna)

The common shelduck, Tadorna tadorna, is a waterfowl species that graces the Euro-Siberian region with its presence. It is a medium-sized bird, akin to a small, short-necked goose, and is quite the sight with its white plumage contrasted by chestnut patches and a black underbelly. The head and neck are a dark, iridescent green, and the bill is a reddish-pink, with the male sporting a conspicuous knob on the forehead during the breeding season. Pink feet complete the ensemble, making this bird a striking figure in its habitat.

To identify the common shelduck, look for the distinctive reddish-pink bill and pink feet. The male, especially in breeding plumage, has a bright red bill with a prominent knob. The female is slightly smaller and has white facial markings. Both sexes have a white body with chestnut patches, a black belly, and a dark green head and neck. In flight, the green and chestnut secondary feathers become visible, contrasting with the predominantly white underwings.

The common shelduck is found in a variety of wetland habitats, including temperate lakes and rivers, as well as estuaries and tidal mudflats in winter. It has a particular fondness for salt marshes and estuaries and is known to breed in rabbit burrows, tree holes, and even haystacks.

This species is widespread across temperate Eurasia. It breeds in temperate regions and migrates to subtropical areas for wintering. Some populations remain resident in the westernmost parts of Europe, while others undertake movements to moulting grounds like the Wadden Sea.

The common shelduck is a sociable bird, often seen in large moulting flocks that can number up to 100,000 individuals. It is known for leaving its young in crèches supervised by a few adults. The species is also covered by the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA), highlighting its ecological importance.

The vocalization of the common shelduck is a loud, unmistakable honk, which can be heard over considerable distances.

During the breeding season, the male's bill becomes particularly vibrant, and the species is known to nest in a variety of locations, from rabbit burrows to tree holes.

While the common shelduck is quite distinctive, it could potentially be confused with other shelduck species. However, its unique coloration and size generally make it easy to distinguish.

The common shelduck feeds on a variety of items, including mollusks and small aquatic creatures, which it often forages for in the mudflats during low tide.

The IUCN Red List classifies the common shelduck as Least Concern, indicating that, currently, there are no immediate threats to its population numbers on a global scale.

18-9-2018 TABLAS DE DAIMIEL, LA MANCHA - FERRUGINOUS DUCK (FEMALE) (Aythya nyroca)

The Ferruginous Duck, known scientifically as Aythya nyroca, is a medium-sized diving duck hailing from the vast expanses of Eurosiberia. The males are adorned with a rich, dark chestnut plumage on their heads, breasts, and flanks, which is set off by the stark white of their undertail coverts. When in flight, their white bellies and underwing patches become conspicuous. Females present a more subdued palette, being duller and browner. A notable feature of the male is its yellow eye, while the female's eye is dark.

To identify the Ferruginous Duck, look for the male's distinctive yellow eye and rich chestnut coloring. In contrast, the female will have a dark eye and a browner hue. When the bird takes to the air, observe the white belly and underwing patch that become visible, aiding in its identification.

The Ferruginous Duck shows a preference for shallow freshwater bodies teeming with rich submerged and floating vegetation. The margins of these waters are often densely populated with emergent vegetation. While it may occasionally inhabit saline or brackish pools or wetlands, during migration and wintering, it is also known to frequent coastal waters, inland seas, and large open lagoons.

This duck's breeding range stretches from Iberia and the Maghreb eastward to western Mongolia, and southward to Arabia. However, in the western part of its range, it has become scarce and localized, with some countries reporting local extirpation. In winter, the species disperses throughout the Mediterranean Basin and the Black Sea, with some migrating into sub-Saharan Africa via the Nile Valley. Eastern populations winter in South and Southeast Asia.

Ferruginous Ducks are sociable, yet they are less so than other species within the Aythya genus. In regions where they are common, they may form large flocks in the winter, often mingling with other diving ducks like tufted ducks and common pochards. They begin pairing from January, and during courtship, males may exhibit a tail-curling behavior that dips the tail into the water, highlighting the white undertail coverts. They may form colonies in protected areas, such as islands, sometimes alongside gulls, or nest singly in more concealed locations when less common.

The nesting period commences at the end of April or the start of May. Nests are constructed on the ground near water or occasionally as floating structures amidst emergent vegetation. The incubation of eggs spans 25–27 days, and the young take 55–60 days to fledge.

18-9-2018 TABLAS DE DAIMIEL, LA MANCHA - GREEN WINGED TEAL (Anas crecca)

The American Green-winged Teal (Anas carolinensis), a diminutive and sprightly member of the dabbling duck family, graces the northern reaches of North America with its presence. This species, once thought to be the same as its Eurasian counterpart, has been recognized as distinct, a testament to its unique characteristics. The male, resplendent in breeding plumage, sports a chestnut head adorned with a striking green eye patch, while the female's mottled brown feathers provide excellent camouflage.

To identify the male Green-winged Teal, look for the combination of grey flanks and back, a yellow rump, and a green speculum edged in white. The vertical white stripe on the side of the breast sets it apart from its Eurasian relative. Females, though more subdued in color, can be recognized by their size, shape, and the speculum. In eclipse plumage, the drake resembles the female, making identification more challenging.

The Green-winged Teal thrives in sheltered wetlands, including taiga bogs and marshes with abundant emergent vegetation. They show a preference for shallow waters and small ponds during the breeding season.

18-9-2018 TABLAS DE DAIMIEL, LA MANCHA - NORTHERN SHOVELER (FEMALE) (Spatula clypeata)

The Northern Shoveler, known in Britain simply as the shoveler, is a distinctive species with a broad, spatulate bill that sets it apart from other ducks. The male, or drake, in breeding plumage boasts an iridescent dark green head, a white chest, and chestnut flanks and belly. When in flight, one can observe the pale blue feathers on the forewing, edged with white and set against a green speculum. The female is more subdued in color, mottled brown akin to other dabblers, but her large, gray bill with orange hints is a clear identifier.

To identify the Northern Shoveler, look for the following characteristics:

Large, spatulate bill

Males: Iridescent dark green head, white chest, chestnut belly and flanks

Females: Mottled brown, similar to a female mallard but with a distinctive bill

In flight: Pale blue forewing feathers with a white border and green speculum

Size: Length of 48 cm (19 in), wingspan of 76 cm (30 in), and weight of 600 g (1.3 lb)

The Northern Shoveler frequents open wetlands such as wet grasslands or marshes with emergent vegetation. They prefer mud-bottomed marshes rich in invertebrate life.

This species has a broad breeding range across northern Europe, the Palearctic, and most of North America. It winters in southern Europe, the Indian subcontinent, Southeast Asia, Central America, the Caribbean, and northern South America. It is a rare vagrant to Australia.

Northern Shovelers are known for their unique foraging behavior, swimming rapidly in circles to create a funnel effect that brings food to the surface. They feed by dabbling for plant food and straining aquatic invertebrates from the water with their specialized bills. During the breeding season, males are territorial and perform elaborate courtship displays. They are fairly quiet, with males emitting a clunking call and females quacking like a mallard.

The male Northern Shoveler produces a clunking call, while the female's vocalization resembles a quack similar to that of a mallard.

Shovelers prefer to nest in grassy areas away from open water. The nest is a shallow depression lined with plant material and down, where the female typically lays about nine eggs. Males defend their territory and mates vigorously during the breeding season.

The diet consists primarily of plant food and aquatic invertebrates. The shoveler's bill is equipped with lamellae, which allow it to efficiently sift food from the water.

The Northern Shoveler is classified as Least Concern on the IUCN Red List, with a healthy and increasing population due to favorable habitat conditions.

18-9-2018 TABLAS DE DAIMIEL, LA MANCHA - NORTHERN SHOVELER (MALE) (Spatula clypeata)

The Northern shoveler (Spatula clypeata) is a widespread species of duck unmistakable in the northern hemisphere due to its large spatulate bill. In Britain, it is known simply as the shoveler. One part of its scientific name Spatula is the Latin for a "spoon" or "spatula"; the other part is derived from the Latin clypeata and can be translated as "shield-bearing".

During the breeding season, the male of this species has an iridescent dark green head, white breast, and chestnut belly and flanks. In flight, pale blue forewing feathers are revealed, separated from the green speculum by a white border. In early fall the male will have a white crescent on each side of the face. In non-breeding (eclipse) plumage, the male resembles the female. The female is a drab mottled brown like other dabblers, with plumage much like a female mallard, but easily distinguished by the long broad bill, which is gray-tinged with orange on the cutting edge and lower mandible. The female's forewing is gray.

18-9-2018 TABLAS DE DAIMIEL, LA MANCHA - COMMON SHELDUCK (Tadorna tadorna)

The common shelduck (Tadorna tadorna) is a waterfowl species of the shelduck genus, Tadorna. It is widespread and common in the Euro-Siberian region of the Palearctic, mainly breeding in temperate and wintering in subtropical regions; in winter, it can also be found in the Maghreb.

Fossil bones from Dorkovo (Bulgaria) described as Balcanas pliocaenica may actually belong to this species. More likely, they are an extinct species of Tadorna (if not a distinct genus) due to their Early Pliocene age; the present species is not unequivocally attested from the fossil record until some 2–3 million years later (Late Pliocene/Early Pleistocene).

The common shelduck resembles a small short-necked goose in size and shape. It is a striking bird, with a reddish-pink bill, pink feet, a white body with chestnut patches and a black belly, and a dark green head and neck. The wing coverts are white, the primary remiges black, and the secondaries green (only showing in flight) and chestnut. The underwings are almost entirely white. Sexes are similar, but the female is smaller, with some white facial markings, while the male is particularly crisply coloured in the breeding season, his bill bright red and bearing a prominent knob at the forehead.

18-9-2018 TABLAS DE DAIMIEL, LA MANCHA - 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.

The species has a broad breeding distribution across warm temperate to tropical regions of Asia, Africa, Australia, and Europe. Northern populations are migratory, wintering in Africa and southern Asia, while others remain as permanent residents in warmer areas.

Little Egrets are social yet territorial when feeding. They exhibit a range of foraging behaviors, from active chasing to patient ambush. Their movements are often in response to the presence of other animals, which may stir up prey.

The Little Egret's vocalizations include croaking and bubbling sounds at breeding colonies and a harsh alarm call when disturbed. These calls are similar to those of the Black-crowned Night Heron and the Cattle Egret.

Breeding colonies are often mixed with other water birds. Nests are platforms of sticks located in trees, shrubs, or reed beds. Clutches typically consist of three to five bluish-green eggs, incubated by both parents for about three weeks. The young fledge at approximately six weeks old.

The diet is diverse, including fish, amphibians, small reptiles, mammals, birds, crustaceans, molluscs, insects, spiders, and worms. The Little Egret employs various hunting techniques, both in water and on land, to capture its prey.

The Little Egret is classified as "Least Concern" by the IUCN. Conservation measures in the 20th century have allowed populations to recover in Europe, and the species has been expanding its range. It is now successfully colonizing new areas, including the New World.

18-9-2018 TABLAS DE DAIMIEL, LA MANCHA - GREAT CRESTED GREBE (Podiceps cristatus)

The great crested grebe, Podiceps cristatus, is a water bird of the grebe family, notable for its striking black and white plumage and elaborate courtship displays. It is the largest grebe species found in the Old World, with some larger species in the Americas.

Adults are unmistakable in summer with ornate head and neck decorations. In winter, they are whiter than most grebes, with a distinctive white above the eye and a pink bill. Juveniles can be identified by their black and white striped heads, which they lose upon reaching adulthood.

This species prefers vegetated areas of freshwater lakes for breeding.

The great crested grebe has three subspecies: P. c. cristatus in Eurasia, P. c. infuscatus in Africa, and P. c. australis in Australia, Tasmania, and the South Island of New Zealand. The European subspecies migrates from colder regions, while the African and Australasian subspecies are mainly sedentary.

The great crested grebe is an excellent swimmer and diver, pursuing fish underwater. Its mating display is particularly elaborate, involving synchronized dances and poses.

The great crested grebe has three subspecies: P. c. cristatus in Eurasia, P. c. infuscatus in Africa, and P. c. australis in Australia, Tasmania, and the South Island of New Zealand. The European subspecies migrates from colder regions, while the African and Australasian subspecies are mainly sedentary.

The great crested grebe is an excellent swimmer and diver, pursuing fish underwater. Its mating display is particularly elaborate, involving synchronized dances and poses.

The call of the great crested grebe is a loud barking "rah-rah-rah," complemented by a clicking "kek" and deep growls.

Both sexes build the nest at the water's edge, and the average clutch consists of four chalky-white eggs. Incubation is shared, starting with the first egg and lasting 27 to 29 days. The precocial young are capable of swimming and diving almost immediately and are taught by the adults.

Their diet mainly consists of fish, supplemented by small crustaceans, insects, small frogs, and newts.

The great crested grebe is listed as Least Concern by the IUCN. Conservation efforts in places like New Zealand's Lake Wānaka have been ongoing since 2013. The species has also been a beneficiary of early protection efforts by the Royal Society for the Protection of Birds in the United Kingdom.

22-9-2018 GANDIA GRAU, VALENCIA - EUROPEAN SHAG (Phalacrocorax aristotelis)

The European shag, or common shag (Gulosus aristotelis), is a medium-large seabird with a distinctive yellow throat-patch. During the breeding season, adults sport a small crest. This species is characterized by its metallic green-tinged sheen and a longish tail, setting it apart from its relatives with a lighter build and a more slender bill.

To identify the European shag, look for a bird measuring 68 to 78 cm in length with a wingspan of 95 to 110 cm. The adult shag has a green sheen on its feathers and a yellow patch on its throat. The bill is lighter and narrower compared to the great cormorant. Juveniles have darker underparts, and the tail consists of 12 feathers, as opposed to the great cormorant's 14.

The European shag is a coastal bird, preferring rocky shores for breeding and nesting. It is rarely found inland, as it is adapted to life at sea.

This species breeds along the rocky coasts of western and southern Europe, southwest Asia, and north Africa. It mainly winters within its breeding range, except for the northernmost populations. The largest colony is found in the Cíes Islands, Spain.

The European shag is a remarkable diver, known to reach depths of up to 61 meters. It is predominantly a benthic feeder, sourcing its prey from the sea bottom. Shags are known to travel significant distances from their roosts to feed. They exhibit a strong diving technique, leaping from the water to gain momentum.

Breeding takes place on coastal cliffs, with nests constructed from seaweed or twigs, bound together with guano. The breeding season is extensive, starting as early as February and in some cases extending to May or later. Typically, three eggs are laid, and chicks are entirely dependent on parental warmth, as they hatch without down.

The European shag can be confused with the great cormorant but is differentiated by its smaller size, lighter build, thinner bill, and the presence of a crest and metallic sheen in breeding adults.

The European shag's diet is diverse, with a preference for sand eels. However, diet composition can vary with environmental conditions, such as ocean warming and windy weather, which can influence prey availability and foraging success.

The IUCN Red List classifies the European shag as Least Concern, indicating that it is not currently at significant risk of widespread decline.

22-9-2018 MONTE CORONA, VALENCIA - GEOMETER MOTH (Genus Charissa)

The geometer moths are moths belonging to the family Geometridae of the insect order Lepidoptera, the moths and butterflies. Their scientific name derives from the Ancient Greek geo γεω (derivative form of γῆ or γαῖα "the earth"), and metron μέτρον "measure" in reference to the way their larvae, or inchworms, appear to measure the earth as they move along in a looping fashion. Geometridae is a very large family, containing around 23,000 described species; over 1400 species from six subfamilies are indigenous to North America alone. A well-known member is the peppered moth, Biston betularia, which has been the subject of numerous studies in population genetics. Several other geometer moths are notorious pests.

Many geometrids have slender abdomens and broad wings which are usually held flat with the hindwings visible. As such, they appear rather butterfly-like, but in most respects they are typical moths. The majority fly at night. They possess a frenulum to link the wings, and the antennae of the males are often feathered. They tend to blend into the background, often with intricate, wavy patterns on their wings. In some species, females have reduced wings (e.g. winter moth and fall cankerworm). Most are of moderate size, about 3 cm (1.2 in) in wingspan, but a range of sizes occur, from 10–50 mm (0.39–1.97 in), and a few (e.g., Dysphania species) reach an even larger size. They have distinctive paired tympanal organs at the base of the abdomen (these are absent in flightless females).

22-9-2018 GANDIA GRAU, VALENCIA - COMMON HIBISCUS (Hibiscus syriacus)

Hibiscus syriacus is a species of flowering plant in the mallow family, Malvaceae. It is native to areas of east Asia, but widely introduced elsewhere, including much of Europe and North America. It was given the epithet syriacus because it had been collected from gardens in Syria. Common names include the rose of Sharon, (especially in North America), Syrian ketmia, shrub althea (or simply althea, and rose mallow (in the United Kingdom). It is the national flower of South Korea and is mentioned in the South Korean national anthem.

Hibiscus syriacus is a hardy deciduous shrub. It is upright and vase-shaped, reaching 2–4 m (7–13 feet) in height, bearing large trumpet-shaped flowers with prominent yellow-tipped white stamens. The flowers are often pink in color, but can also be dark pink (almost purple), light pink or white. Individual flowers are short-lived, lasting only a day. However, numerous buds produced on the shrub's new growth provide prolific flowering over a long summer blooming period. The soil in which the Hibiscus thrives is moist but well-drained, and organically rich. Hibiscus syriacus is highly tolerant of air pollution, heat, humidity, poor soil and drought. The species has naturalized very well in many suburban areas and might even be termed slightly invasive, so frequently does it seed.

22-9-2018 GANDIA GRAU, VALENCIA - AUDOUIN'S GULL (JUVENILE) (Ichthyaetus audouinii)

The Audouin's gull, Ichthyaetus audouinii, presents itself as a large gull species, predominantly inhabiting the Mediterranean, the western coast of Saharan Africa, and the Iberian Peninsula. Its name pays homage to the French naturalist Jean Victoire Audouin. Resembling a small European herring gull, the adult Audouin's gull is distinguished by its short, stubby red bill and the unique "string of pearls" white wing primary tips. The legs of this bird are a subtle grey-green, and it takes a full four years for the gull to don its adult plumage.

When observing the Audouin's gull, one should note the red bill and the distinctive pattern of white spots along the wingtips, which contrast with the larger "mirrors" seen in other gull species. These features are key to distinguishing it from its relatives.

This gull favors coastal and pelagic environments, strictly adhering to regions where it can pursue its specialized diet.

The Audouin's gull is found in the Mediterranean, along the western Saharan African coast, and on the Iberian Peninsula. It breeds on small islands, either colonially or in solitude. 

Once considered one of the world's rarest gulls, the Audouin's gull has established new colonies but remains a rare sight with a population of around 10,000 pairs. This bird is not known to wander far from its breeding grounds, though occasional records exist of it appearing as far afield as the Netherlands, England, and even Trinidad.

Unlike many of its kin, the Audouin's gull does not scavenge but is a specialist fish eater. It feeds at night, often far out to sea, and also patrols beaches, occasionally dipping its legs into the water to create drag, aiding in its hunting technique.

The Audouin's gull breeds on small islands, laying 2-3 eggs in a ground nest. It has been known to breed both in colonies and as solitary pairs.

The Audouin's gull is currently classified as Vulnerable according to the IUCN Red List. It is also one of the species protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

18-9-2018 TABLAS DE DAIMIEL, LA MANCHA - WHITE HEADED DUCK (FEMALE) (Oxyura leucocephala)

The White-headed Duck, Oxyura leucocephala, presents a striking figure with its distinctive plumage and stout build. Males are adorned with a white head contrasted by a black crown, a blue bill, and a body cloaked in shades of reddish-grey. Females, on the other hand, exhibit a more subdued palette with a dark bill and less vibrant colouring.

Upon encountering this species, one can identify the male by its white head, black cap, and neck, and a blue bill, while the female can be recognized by her grey-brown body, white face, and darker bill and cap. These ducks measure between 43–48 cm in length and weigh approximately 580–750 g.

The White-headed Duck favors lakes with open water and dense vegetation along the margins, which provide essential cover and nesting sites. These habitats include natural lakes and ponds as well as man-made water bodies.

This species has a breeding range that spans from Spain and North Africa to western and central Asia. Sightings have been reported north of their typical range, though the status of these observations is often uncertain due to the potential for escapees from captivity.

The White-headed Duck is an adept diver and swimmer, often opting to escape threats by swimming rather than taking flight. It exhibits a preference for aquatic environments where it can forage and seek refuge.

An omnivorous diet characterizes this species, with a strong inclination towards vegetable matter. They forage by diving and swimming underwater, and display a notable reluctance to fly.

The International Union for Conservation of Nature (IUCN) has classified the White-headed Duck as "Endangered." Populations have seen a significant decline over the past decade, primarily due to habitat loss and hunting. Additionally, the Spanish population faces genetic dilution from interbreeding with the introduced Ruddy Duck (Oxyura jamaicensis), prompting conservation efforts to eradicate the non-native species from western Europe. The species is also protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

The Eurasian magpie, or common magpie (Pica pica), is a striking bird that graces the northern reaches of the Eurasian continent. It is a member of the crow family, known as corvids, and is part of the "monochrome" magpie group within the Holarctic radiation. The bird is easily recognized by its black and white plumage and long, iridescent tail.

Adult Eurasian magpies measure 44–46 cm in length, with over half of this being the tail. They have a wingspan of 52–62 cm. The head, neck, and breast are glossy black with a metallic sheen of green and violet, while the belly and scapulars are pure white. The wings are black with green or purple gloss, and the primaries have white inner webs. The tail is black with green and reddish-purple gloss. Both sexes have similar plumage, though females are slightly smaller.

The Eurasian magpie favors open countryside with scattered trees, avoiding dense forests and treeless areas. It adapts well to suburban environments, including parks and gardens, and can be found in city centers.

This magpie's range spans temperate Eurasia from the western edges of Portugal and Spain to the eastern limits of the Kamchatka Peninsula.

The Eurasian magpie is known for its intelligence, comparable to that of great apes. It is monogamous, with pairs often remaining together across seasons. They are sedentary, though northern populations may move south in severe weather.

The magpie's call is a distinctive "chac-chac" or a repetitive "chac-chac-chac-chac." Young birds emit a similar call and a high-pitched "Uik Uik," which can resemble a small dog's bark.

Magpies typically breed after their first year. They build large, domed nests in tall trees, laying clutches of five to six pale blue-green eggs, which are incubated for 21–22 days. The chicks are altricial and fledge at around 27 days, with parental care continuing for several weeks.

The Eurasian magpie can be confused with the North American black-billed magpie (Pica hudsonia), though they are now considered separate species.

Omnivorous, the Eurasian magpie's diet includes young birds, eggs, small mammals, insects, carrion, acorns, grain, and other plant matter.

With an extensive range and stable population trends in Europe, the Eurasian magpie is classified by the IUCN as Least Concern. Estimates suggest a total population of 46 to 228 million individuals globally.
