9-1-2019 ALBUFERA, VALENCIA - BLACK HEADED GULL (Chroicocephalus ridibundus)


The black-headed gull (Chroicocephalus ridibundus) is a small gull that breeds in much of the Palearctic in Europe and Asia, and also locally in smaller numbers in coastal eastern Canada. Most of the population is migratory and winters further south, but many also remain in the milder areas of northwestern Europe. It was formerly sometimes cited as "common black-headed gull" to distinguish it from "great black-headed gull" (an old name for Pallas's gull).

Black-headed gulls were among the birds most heavily hit by the 2023 avian influenza outbreak, with over 4,000 birds killed in Great Britain by early May; similarly high mortality rates were also reported from France, the Netherlands, Italy and Germany.


The black-headed gull is a bold and opportunistic feeder. It eats insects, fish, seeds, worms, scraps, and carrion in towns, or invertebrates in ploughed fields with equal facility. It is a noisy species, especially in colonies, with a familiar "kree-ar" call.

It displays a variety of behaviour and adaptations. Some of these include removing eggshells from the nest after hatching, begging co-ordination between siblings, differences between sexes, conspecific brood parasitism, and extra-pair paternity. They are found in a variety of different habitats.

9-1-2018 ALBUFERA, VALENCIA - GREY WAGTAIL (Motacilla cinerea)


The Grey Wagtail, Motacilla cinerea, is a slender bird of the wagtail family, Motacillidae, with an overall length of approximately 18–19 cm. It bears a resemblance to the Yellow Wagtail but is distinguished by the yellow on its underside being confined to the throat and vent. The male, during the breeding season, is characterized by a striking black throat.

This species can be identified by its narrow white supercilium and a broken eye ring. The upperparts are a soft grey, while the underparts are predominantly whitish, with a contrasting yellow vent. Breeding males are notable for their black throats bordered by whitish moustachial stripes.

The Grey Wagtail is invariably found in association with running water during the breeding season. It may nest in natural settings or utilize man-made structures close to streams. Outside of breeding times, it can also be observed around lakes, coasts, and other watery environments.

The Grey Wagtail has a wide distribution across Eurosiberia, with several populations breeding in this region and migrating to tropical areas in Asia and Africa. Subspecies are found in the Azores, Madeira, Canary Islands, and from western Europe to central, east, and northeast Asia.

9-1-2018 ALBUFERA, VALENCIA - COMMON WATER CROWFOOT (Ranunculus aquatilis)


A member of the buttercup family, Common water-crowfoot displays white, buttercup-like flowers with yellow centres. It can form mats in ponds, ditches and streams during spring and summer.

Scientific name is Ranunculus aquatilis.

It can be seen in the UK from May to September.


Ranunculus aquatilis, the common water-crowfoot or white water-crowfoot, is a plant species of the genus Ranunculus, native throughout most of Europe and western North America, and also northwest Africa.

This is an aquatic plant, growing in mats on the surface of water. It has branching thread-like underwater leaves and toothed floater leaves. In fast flowing water the floaters may not be grown. The flowers are white petaled with yellow centres and are held a centimetre or two above the water. The floater leaves are used as props for the flowers and are grown at the same time.

6-1-2019 PEGO MARJAL, ALICANTE - 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. 

6-1-2019 PEGO MARJAL, 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 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.

8-1-2019 OLIVA CAMPO, VALENCIA - COMMON CHAFFINCH (MALE) (Fringilla coelebs)


The adult male Common chaffinch has a black forehead and a blue-grey crown, nape and upper mantle. The rump is a light olive-green; the lower mantle and scapulars form a brown saddle. The side of the head, throat and breast are a dull rust-red merging to pale creamy pink on the belly. The central pair of tail feathers are dark grey with a black shaft streak. The rest of the tail is black apart from the two outer feathers on each side which have white wedges. Each wing has a contrasting white panel on the coverts and a buff-white bar on the secondaries and inner primaries. The flight feathers are black with white on the basal portions of the vanes. 


The secondaries and inner primaries have pale yellow fringes on the outer web whereas the outer primaries have a white outer edge. After the autumn moult, the tips of the new feathers have a buff fringe that adds a brown cast to the coloured plumage. The ends of the feathers wear away over the winter so that by the spring breeding season the underlying brighter colours are displayed. The eyes have dark brown irises and the legs are grey-brown. In winter the bill is a pale grey and slightly darker along the upper ridge or culmen, but in spring the bill becomes bluish-grey with a small black tip. The adult female is much duller in appearance than the male. The head and most of the upperparts are shades of grey-brown. The underparts are paler. The lower back and rump are a dull olive green. The wings and tail are similar to those of the male. The juvenile resembles the female.

7-1-2019 GANDIA MARJAL, 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.

7-1-2019 GANDIA MARJAL, VALENCIA - EURASIAN COOT (Fulica atra)


The Eurasian coot, Fulica atra, also known as the common coot or Australian coot, is a distinctive waterbird with a slaty-black body, a glossy black head, and a striking white bill topped with a white frontal shield. This bird is a member of the Rallidae family, which includes rails and crakes. Both sexes exhibit similar plumage, making them indistinguishable in the field.

Adult Eurasian coots measure 36–38 cm in length with a wingspan of 70–80 cm. Males are slightly heavier than females, weighing around 890 g compared to the females' 750 g. The species is characterized by its white bill and frontal shield, which contrast sharply with its all-black body. Juveniles are paler with a whitish breast and lack the facial shield, which develops fully by one year of age.

The Eurasian coot is found on freshwater lakes and ponds and has adapted well to urban environments, often seen in city parks and gardens with water bodies.

This bird has a broad range across the Old World, including Europe, Asia, Australia, New Zealand, and parts of North Africa. It is a resident in milder regions but migrates south and west from much of Asia during winter.


The Eurasian coot is less secretive than many rails, often visible on open water or grasslands. It is territorial and aggressive during the breeding season, with both parents defending their territory. In non-breeding seasons, coots may form large flocks. They are reluctant flyers, preferring to run across water surfaces, and are known for bobbing their heads while swimming.

This species is known for its noisy demeanor, producing a variety of crackling, explosive, or trumpeting calls, which are often heard at night.

Coots build bulky, sometimes floating nests, concealed in vegetation or in the open. Both sexes construct the nest, with the male gathering materials. Clutches typically contain 6-10 buff-colored eggs speckled with black or dark brown. Both parents incubate the eggs, which hatch after 21-24 days. Chicks are precocial and nidifugous, with distinctive orange-red tips on their down.

Omnivorous in nature, the Eurasian coot consumes small live prey, including other birds' eggs, as well as algae, vegetation, seeds, and fruit. It employs various feeding techniques, both on land and in water.

The Eurasian coot is classified as Least Concern by the IUCN and is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

7-1-2019 GANDIA MARJAL, VALENCIA - MALLARD (MALE) (Anas platyrhynchos)


The Mallard, or wild duck (Anas platyrhynchos), is a familiar and widespread dabbling duck with a presence across temperate and subtropical regions of the Americas, Eurasia, and North Africa. It has also been introduced to parts of the Southern Hemisphere. The male is renowned for its iridescent green head and white collar, while the female sports a brown-speckled plumage. Both sexes boast a speculum—a patch of feathers with iridescent purple or blue hues bordered by white. The Mallard's length ranges from 50 to 65 cm, with a wingspan of 81 to 98 cm, and it typically weighs between 0.7 and 1.6 kg.

Males during the breeding season are unmistakable with their glossy green heads, white collars, and purple-tinged brown breasts. Females are mottled brown with buff cheeks and an eye-stripe. Both sexes have the distinctive speculum on their wings. The male's bill is yellowish-orange tipped with black, while the female's is darker, ranging from black to mottled orange and brown.


Mallards are found in a variety of wetlands, including parks, small ponds, rivers, lakes, and estuaries. They prefer water depths less than 0.9 meters and are drawn to areas with aquatic vegetation.

This species is distributed across the Northern and Southern Hemispheres, from Alaska to Mexico, the Hawaiian Islands, across the Palearctic, and down to southeastern and southwestern Australia and New Zealand.

Mallards are social birds that often form large flocks outside the breeding season. They are adaptable and can thrive in urban areas. The species is migratory in the northern parts of its range.


The female Mallard is known for its quintessential "quack," while the male's call is a quieter and deeper version of the female's. Vocalizations can vary by region, with urban ducks being louder than their rural counterparts.

Breeding pairs form in the fall, with the female laying 8 to 13 creamy white to greenish-buff eggs. Incubation lasts 27 to 28 days, and ducklings are precocial, swimming immediately after hatching.

Mallards are omnivorous, feeding on a variety of foods including seeds, plant matter, insects, crustaceans, and small animals. Their diet varies with the season and breeding cycle.

The Mallard is classified as Least Concern by the IUCN. However, it is considered invasive in some regions, where it can hybridize with and threaten local duck species.

7-1-2019 GANDIA MARJAL, VALENCIA - EUROPEAN ROBIN (Erithacus rubecula)


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. 


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.

6-1-2019 PEGO MARJAL, ALICANTE - WHITE STORK (Ciconia ciconia)


The White Stork (Ciconia ciconia) is a majestic bird, notable for its predominantly white plumage with contrasting black flight feathers. Adults boast impressive red legs and long, pointed red beaks. They average a length of 100–115 cm from beak to tail and have a wingspan ranging from 155 to 215 cm.

To identify the White Stork, look for its white body, black wingtips, and distinctive red legs and beak. In flight, they extend their necks and legs, presenting a stretched-out appearance. Juveniles have duller beaks and legs, which become brighter as they mature.

White Storks favor open farmlands, grassy meadows, and shallow wetlands. They avoid dense vegetation, preferring areas where they can easily spot and access their prey.

The White Stork breeds across Europe, northwestern Africa, southwestern Asia, and southern Africa. It is a long-distance migrant, wintering as far south as South Africa and on the Indian subcontinent.


These social birds can be seen in flocks, especially during migration. They are monogamous breeders, with both parents involved in nest building and care of the young. They walk with a slow, steady gait and rest with their heads hunched between their shoulders.

The White Stork is largely silent, but it is known for its bill-clattering display, which resonates from its throat pouch and serves as a form of communication.

White Storks build large stick nests, often reused for several years. Females lay clutches of usually four eggs, with both parents sharing incubation duties. The young fledge after about two months but remain dependent on their parents for a short while thereafter.


The White Stork can be confused with the yellow-billed stork, great white pelican, and Egyptian vulture when seen at a distance in flight. However, differences in beak shape, leg length, and flight posture can help distinguish these species.

As carnivores, White Storks consume a variety of prey, including insects, fish, amphibians, reptiles, small mammals, and occasionally small birds. They forage on the ground and in shallow waters.

The White Stork is classified as Least Concern by the IUCN. Its populations have benefited from conservation efforts, leading to reintroduction in areas where it had previously disappeared due to changes in land use and industrialization.

6-1-2019 PEGO MARJAL, ALICANTE - WATER PIPIT (Anthus spinoletta)


The water pipit (Anthus spinoletta) is a small passerine bird which breeds in the mountains of Southern Europe and the Palearctic eastwards to China. It is a short-distance migrant; many birds move to lower altitudes or wet open lowlands in winter.

The water pipit in breeding plumage has greyish-brown upperparts, weakly streaked with darker brown, and pale pink-buff underparts fading to whitish on the lower belly. The head is grey with a broad white supercilium ("eyebrow"), and the outer tail feathers are white. In winter, the head is grey-brown, the supercilium is duller, the upperparts are more streaked, and the underparts are white, streaked lightly with brown on the breast and flanks.

There are only minor differences among the three subspecies, the sexes are almost identical, and young birds resemble adults. The water pipit's song is delivered from a perch or in flight, and consists of four or five blocks, each consisting of about six repetitions of a different short note.

6-1-2019 PEGO MARJAL, ALICANTE - GLOSSY IBIS (Plegadis falcinellus)


The Glossy Ibis, Plegadis falcinellus, is a wading bird of the family Threskiornithidae, known for its striking, sickle-shaped bill. This mid-sized ibis measures 48–66 cm in length, with a wingspan of 80–105 cm. Breeding adults boast reddish-brown bodies and iridescent bottle-green wings, while non-breeders and juveniles display a more subdued coloration. The species is characterized by a brownish bill, dark facial skin with blue-gray to cobalt blue borders, and red-brown legs. In flight, the ibis extends its neck and exhibits a graceful V formation.
When identifying the Glossy Ibis, look for its unique glossy feathers and the distinct shape of its bill. The bird's flight pattern is also a telltale sign, as it flies with its neck outstretched, unlike herons. Listen for its various croaks and grunts, particularly the hoarse grrrr sound during the breeding season.


The Glossy Ibis favors freshwater or brackish wetlands with tall, dense emergent vegetation such as reeds, papyrus, or rushes, and low trees or bushes. It can also be found in lagoons, floodplains, wet meadows, swamps, reservoirs, sewage ponds, rice paddies, and irrigated farmland. Coastal habitats like estuaries and salt marshes are less common for this species.

This ibis is the most widespread of its kind, breeding in warm regions across Europe, Asia, Africa, Australia, and the Americas. It is migratory, with European birds wintering in Africa and North American birds migrating southward. The species has been expanding its range, with increasing numbers in Europe and successful breeding in Britain as of 2022.

The Glossy Ibis is known for its nomadic tendencies and dispersal movements post-breeding. Northern populations are migratory, traversing vast distances such as the Sahara Desert. The species nests in mixed colonies and forms large flocks during migration and winter. It often roosts communally with other species, sometimes in trees far from feeding areas.

6-1-2019 PEGO MARJAL, ALICANTE - EUROPEAN STONECHAT (Saxicola rubicola)


The European stonechat, Saxicola rubicola, is a small, charming passerine bird, once thought to be a member of the thrush family but now placed within the Old World flycatcher family, Muscicapidae. This species exhibits a striking sexual dimorphism, with males donning a black plumage with vibrant orange throats and females wearing a more subdued brown.

Males in their summer plumage are unmistakable with their black heads, orange throats, and white bellies. They also sport a distinctive white half-collar and small white patches on the wings and rump. Females, on the other hand, are predominantly brown with less pronounced white wing patches. Both sexes have notably short wings, which are shorter than those of their migratory relatives.

The European stonechat favors heathlands, coastal dunes, and open grasslands dotted with shrubs, brambles, and heather. These habitats provide the perfect backdrop for their active foraging and breeding behaviors.

6-1-2019 PEGO MARJAL, ALICANTE - 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.

6-1-2019 ADOR CAMPO, VALENCIA - LITTLE OWL (Athene noctua)


This owl usually perches in an elevated position ready to swoop down on any small creature it notices. It feeds on prey such as insects and earthworms, as well as small vertebrates including amphibians, reptiles, birds and mammals. It may pursue prey on the ground and it caches surplus food in holes or other hiding places. A study of the pellets of indigestible material that the birds regurgitate found mammals formed 20 to 50% of the diet and insects 24 to 49%. Mammals taken included mice, rats, voles, shrews, moles and rabbits. The birds were mostly taken during the breeding season and were often fledglings, and including the chicks of game birds. The insects included Diptera, Dermaptera, Coleoptera, Lepidoptera and Hymenoptera. Some vegetable matter (up to 5%) was included in the diet and may have been ingested incidentally.

The little owl is territorial, the male normally remaining in one territory for life. However, the boundaries may expand and contract, being largest in the courtship season in spring. The home range, in which the bird actually hunts for food, varies with the type of habitat and time of year. Little owls with home-ranges that incorporate a high diversity of habitats are much smaller (< 2 ha) than those which breed in monotonous farmland (with home-ranges over 12 ha). Larger home-ranges result in increased flight activity, longer foraging trips and fewer nest visits. If a male intrudes into the territory of another, the occupier approaches and emits its territorial calls. If the intruder persists, the occupier flies at him aggressively. If this is unsuccessful, the occupier repeats the attack, this time trying to make contact with his claws. In retreat, an owl often drops to the ground and makes a low-level escape. The territory is more actively defended against a strange male as compared to a known male from a neighbouring territory; it has been shown that the little owl can recognise familiar birds by voice.


The little owl is partly diurnal and often perches boldly and prominently during the day. If living in an area with a large amount of human activity, little owls may grow used to humans and will remain on their perch, often in full view, while people are around. The little owl has a life expectancy of about 16 years. However, many birds do not reach maturity; severe winters can take their toll and some birds are killed by road vehicles at night, so the average lifespan may be on the order of 3 years.

This owl becomes more vocal at night as the breeding season approaches in late spring. The nesting location varies with habitat, nests being found in holes in trees, in cliffs, quarries, walls, old buildings, river banks and rabbit burrows. A clutch of 3 to 5 eggs is laid (occasionally 2 to 8). The eggs are broadly elliptical, white and without gloss; they measure about 35.5 by 29.5 mm (1.40 by 1.16 in). They are incubated by the female who sometimes starts sitting after the first egg is laid. While she is incubating the eggs, the male brings food for her. The eggs hatch after 28 or 29 days. At first the chicks are brooded by the female and the male brings in food which she distributes to them. Later, both parents are involved in hunting and feeding them. The young leave the nest at about 7 weeks, and can fly a week or two later. Usually there is a single brood but when food is abundant, there may be two. The energy reserves that little owl chicks are able to build up when in the nest influences their post-fledgling survival, with birds in good physical condition having a much higher chance of survival than those in poor condition. When the young disperse, they seldom travel more than about 20 km (12 mi). Pairs of birds often remain together all year round and the bond may last until one partner dies.

6-1-2019 PEGO MARJAL, ALICANTE - COMMON BUZZARD (Buteo buteo)


Common buzzards are medium-sized birds of prey found across Europe, Asia, and Africa, known for their broad wings and fan-shaped tail, and have a varied diet that includes small mammals, birds, and carrion. They are adaptable and can live in diverse habitats, are generally monogamous and mate for life, and have a lifespan of around 8-12 years.

4-1-2016 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). 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.

In Culture
The red admiral features in several works of Vladimir Nabokov: Speak, Memory (1951), Pale Fire (1962), and King, Queen, Knave (1968).


The forewing of this butterfly bears on a black ground an oblique vermilion bandand a group of white subapical spots. On the hindwing the larger portion of the distal margin is red, with a row of small black spots and at the anal angle an elongate blue spot. The underside is partly variegated with blue; the forewing is on the whole similar in markings to the upper, while the hindwing is brightly variegated and clouded, bearing black markings, of which those in the cell resemble a figure (on the left wing 18 or 98, on the right 81 or 89); in the middle of the costal area there is a pale patch and in the distal marginal area a row of ocellus-like spots. Sometimes, especially in the female, the red band of the forewing bearsa small white spot in the middle.

The red admiral is found in temperate regions of North Africa, North and Central America, Europe, Asia, and island regions of Hawaii, and the Caribbean.

In northern Europe, it is one of the last butterflies to be seen before winter sets in, often feeding on the flowers of ivy on sunny days. The red admiral is also known to hibernate, re-emerging individuals showing prominently darker colors than the first brood. The butterfly also flies on sunny winter days, especially in southern Europe.

In North America, the red admiral generally has two broods from March through October. Most of North America must be recolonized each spring by southern migrants, but the species overwinters in south Texas.


Male red admirals are territorial and perch during the afternoon until sunset. Larger territories are optimal and subject to intrusion by other males more frequently than smaller territories. Territories tend to be oval, 8–24 feet (2.4–7.3 m) long and 13–42 feet (4.0–12.8 m) wide. Males patrol their territory by flying around the perimeter between 7 and 30 times per hour. On average, territory holders interact with intruders 10 to 15 times per hour.

When another male encroaches on a red admiral's territory, the resident chases away the intruder, often in a vertical, helical path to disorient or tire out the intruder while minimizing the horizontal distance it travels from its perch. The red admiral immediately returns to its territory after chasing off encroaching males. Time spent patrolling increases as number of the intruder interactions increases.

Patrolling behavior is correlated with warmer air temperatures, so males begin patrolling early and continue later on warmer days. Overcast skies usually led to patrolling later in the day. It is not clear whether this later start time is due to lower air temperature or a direct effect of decreased solar radiation. Another theory is that males believe it is earlier in the morning on cloudy days because of the reduced solar radiation.

Mating usually occurs in late autumn or early winter following collective migration to southern regions with a warmer climate. The red admiral's main host plant, stinging nettle, is most abundant during this migration. Larval development proceeds through winter and adults are first sighted in early spring. The new generation of adults migrates north before mating, because food is usually diminished by late spring. In Europe, the cyclic nature of this migration has been confirmed by analysing stable isotopes of wing samples. In spring, individuals arriving at northern Europe (Kaliningrad) were of a southern origin, while in autumn the isotope analyses revealed that samples came from the surrounding area or northern latitudes. During migration, the red admiral flies at high altitudes where high-speed winds carry the butterfly, reducing energy expenditure.

4-1-2016 MONTE CORONA, VALENCIA - CULICINE MOSQUITO (Culiseta longiareolata)


The Culicinae are the most extensive subfamily of mosquitoes (Culicidae) and have species in every continent except Antarctica, but are highly concentrated in tropical areas. Mosquitoes are best known as parasites to many vertebrate animals and vectors for disease. They are holometabolous insects, and most species lay their eggs in stagnant water, to benefit their aquatic larval stage.

The subfamily Culicinae is the largest subfamily of Culicidae, a family of Nematocera dipterans. There are 3,046 species of Culicinae mosquitoes, in 108 genera and 11 tribes. Members of the Culicinae subfamily are small flies with fore wings for flight and hind wings reduced to halteres for balance. The mosquitoes also have long, slender, legs and proboscis-style mouth parts for feeding on vertebrate blood or plant fluids. Only the females are blood feeders, requiring a high quality protein meal before they can oviposit. Because the mosquitoes are well adapted for finding hosts, the females can move quickly from one blood meal to another, and when injecting their saliva, can inject pathogens picked up from other hosts and thus efficiently spread disease.


Culicinae mosquitoes are holometabolous, going through four distinct life stages: egg, larva, pupa, and adult. The duration of each stage is species-specific, but all Culicinae mosquitoes are multivoltine. The egg, larval, and pupal stages are aquatic. Adults leave the water by flight to find plants or vertebrates on which to feed. Oviposition can occur in natural reservoirs of salt water or fresh water, or temporary pools, but oviposition sites are generally stagnant. All Psorophora and some Aedes species oviposit on soil where the eggs remain, unhatched, till flooded. Many species associate closely with humans, using accumulated ground water in developed areas for oviposition. Some species use plant cavities for oviposition. These species can, as larvae, drill into the plant for air.

Culicinae eggs are laid in groups by adult females, often numbering over a hundred. Most species lay the eggs on the surface of stagnant water. The female lays the eggs vertically and side by side, held together by a sticky substance excreted to coat the eggs, head end down, creating an egg raft that is convex below and concave above with ends that are typically upturned. Species that use this form of egg-laying typically hatch as first instar larvae within a few hours of laying. Oviposition on the surface of stagnant water is most common, but some species of Aedes and all Psorophora deposit their eggs in areas that will flood. Eggs are laid and embryological development occurs, but the eggs do not hatch till flooded. After flooding, the eggs will hatch within two to three days

4-1-2016 MARCHUQUERIA, VALENCIA - BLACK REDSTART (MALE) (Phoenicurus ochruros)


The Black redstart (Phoenicurus ochruros) is a small passerine bird in the genus Phoenicurus. Like its relatives, it was formerly classed as a member of the thrush family (Turdidae), but is now known to be an Old World flycatcher (Muscicapidae).

The adult male of this species is overall dark grey to black on the upperparts and with a black breast; the lower rump and tail are orange-red, with the two central tail feathers dark red-brown. The belly and undertail are either blackish-grey (western subspecies) or orange-red (eastern subspecies); the wings are blackish-grey with pale fringes on the secondaries forming a whitish panel (western subspecies) or all blackish (eastern subspecies). The female is grey (western subspecies) to grey-brown (eastern subspecies) overall except for the orange-red lower rump and tail, greyer than the common redstart; at any age, the grey axillaries and underwing coverts are also distinctive. There are two distinct forms in first calendar year males at least in western subspecies, with the first ('carei') being similar to females and the second ('paradoxus') approaching adult males but lacking the whitish wing panel that does only develop during post-breeding molt of wing feathers in the second calendar year. This second form is much rarer than the first.


Black redstarts breed in south and central Europe and Asia and north-west Africa, from Great Britain and Ireland (where local) south to Morocco, east to central China. They are resident in the milder parts of their range, but north-eastern birds migrate to winter in southern and western Europe and Asia, and north Africa. In some areas, birds that breed in mountains move to lower elevations in winter. Black redstarts inhabit stony ground in mountains, particularly cliffs and stony slopes with xerophytic vegetation. They are also found in villages, and urban areas and often occur in large industrial complexes that have bare areas and cliff-like buildings.

1-1-2019 ALBUFERA, VALENCIA - SPOTLESS STARLING (Sturnus unicolor)


The Spotless Starling, known scientifically as Sturnus unicolor, is a member of the starling family, Sturnidae. It bears a striking resemblance to its cousin, the Common Starling, but is distinguished by its slightly larger size, measuring 21-23 cm in length and weighing between 70-100 grams. Its plumage is a glossy, oily black, which may exhibit purple or green iridescence under bright light. Notably, during the spring and summer, its feathers are completely devoid of spots, while in winter, it sports only minuscule pale spots.

To identify the Spotless Starling, look for its longer throat feathers, which are double the length of those on the Common Starling, creating a pronounced "beard" especially visible when the bird vocalizes. Its legs are a vivid pink, and the bill color changes with the seasons: yellow with a bluish or pinkish base in summer, and a duller, often blackish hue in winter. Juveniles present a dull brown plumage, darker than their common counterparts, with a black bill and brown legs.

The Spotless Starling is quite adaptable, inhabiting a variety of open environments from farmlands and olive groves to urban areas. It thrives particularly well in open grazed holm oak woods and in cities like Gibraltar, where it is a common sight.

This bird has a more restricted range compared to the Common Starling, being native to the Iberian Peninsula, Northwest Africa, southernmost France, and the islands of Sicily, Corsica, and Sardinia. It is largely sedentary, with its population having expanded northward in recent decades.
