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.

1-1-2019 ALBUFERA, VALENCIA - EUROPEAN STONECHAT (FEMALE) (Saxicola rubicola)


1-1-2019 ALBUFERA, 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.

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.


The Little egret (Egretta garzetta) is small elegant heron in the family Ardeidae. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. At one time common in Western Europe, the Little heron was hunted extensively in the 19th century to provide plumes for the decoration of hats and became locally extinct in Northwestern Europe and scarce in the south. Around 1950, conservation laws were introduced in southern Europe to protect the species and their numbers began to increase.

The plumage of the Little egret is normally entirely white, although there are dark forms with largely bluish-grey plumage. In the breeding season, the adult has two long plumes on the nape that form a crest. These plumes are about 150 mm (6 in) and are pointed and very narrow. There are similar feathers on the breast, but the barbs are more widely spread.

In the breeding season, the adult has two long plumes on the nape that form a crest. These plumes are about 150 mm (6 in) and are pointed and very narrow. There are similar feathers on the breast, but the barbs are more widely spread. There are also several elongated scapular feathers that have long loose barbs and may be 200 mm (8 in) long. During the winter the plumage is similar but the scapulars are shorter and more normal in appearance. The bill is long and slender and it and the lores are black. There is an area of greenish-grey bare skin at the base of the lower mandible and around the eye which has a yellow iris. The legs are black and the feet yellow. Juveniles are similar to non-breeding adults but have greenish-black legs and duller yellow feet, and may have a certain proportion of greyish or brownish feathers. The subspecies nigripes differs in having yellow skin between the bill and eye, and blackish feet. During the height of courtship, the lores turn red and the feet of the yellow-footed races turn red.

Little egrets are sociable birds and are often seen in small flocks. They are diurnal birds and feed mainly in the early morning and in the late afternoon. They use a variety of methods to procure their food; they stalk their prey in shallow water, often running with raised wings or shuffling their feet to disturb small fish, or may stand still and wait to ambush prey. Little egrets also make use of opportunities provided by cormorants disturbing fish or humans attracting fish by throwing bread into the water. On land, they walk or run while chasing their prey, feed on creatures disturbed by grazing livestock and ticks on the livestock, and even scavenge occasionally. Little egrets are silent birds in general, however, at their breeding colonies, they make various croaking and bubbling calls. When disturbed, they produce a harsh alarm call.

1-1-2019 ALBUFERA, VALENCIA - WHITE WAGTAIL (Motacilla alba)


The white wagtail (Motacilla alba) is a small passerine bird in the family Motacillidae, which also includes pipits and longclaws. The species breeds in the Palearctic zone in most of Europe and Asia and parts of North Africa; it also has a toehold in western Alaska as a scarce breeder. It is resident in the mildest parts of its range, but otherwise migrates to Africa. In total, there are between 9 and 11 subspecies of M. alba; in Ireland and Great Britain, the black-backed subspecies known as the pied wagtail (M. a. yarrellii) predominates.

The white wagtail is an insectivorous bird of open country, often near habitation and water. It prefers bare areas for feeding, where it can see and pursue its prey. In urban areas, it has adapted to foraging on paved areas such as car parks. It nests in crevices in stone walls and similar natural and human-made structures. 


This species breeds throughout Eurasia up to latitudes 75°N, only being absent in the Arctic from areas where the July isotherm is less than 4 °C. It also breeds in the mountains of Morocco and western Alaska. It occupies a wide range of habitats, but is absent from deserts. White wagtails are residents in the milder parts of its range such as western Europe and the Mediterranean, but migratory in much of the rest of its range. Northern European breeders winter around the Mediterranean and in tropical and subtropical Africa, and Asiatic birds move to the Middle East, India, and Southeast Asia. Birds from the North American population also winter in tropical Asia.

It is the national bird of Latvia and has featured on the stamps of several countries. It is listed as being 'of least concern' by IUCN.

1-1-2019 ALBUFERA, VALENCIA - EUROPEAN STONECHAT (Saxicola rubicola)





1-1-2019 ALBUFERA, VALENCIA - EURASIAN KESTREL (Falco tinnunculus)


The common kestrel, Falco tinnunculus, is a bird of prey from the kestrel group within the falcon family Falconidae. It is also known as the European kestrel, Eurasian kestrel, or Old World kestrel. In the United Kingdom, it is often simply referred to as the "kestrel." This raptor is small compared to other birds of prey but larger than most songbirds, with long wings and a distinctive long tail.

Males and females exhibit sexual dimorphism in their plumage. The male has a blue-grey cap and tail with a black tip bordered by a narrow white rim. Its back is chestnut with black spots, and the underside is buff with black streaks. The female is larger and lacks the blue-grey coloring, having a brown back with black bars and a similar underside to the male. Both sexes have a prominent black malar stripe, bright yellow cere, feet, and eye-ring, with dark toenails, bill, and iris.

The common kestrel favors open habitats such as fields, heaths, shrubland, and marshland. It does not require woodland but needs alternative perching and nesting sites like rocks or buildings. It thrives in treeless steppes and can adapt to human settlements and various landscapes, from wetlands to arid savannas.

1-1-2019 ALBUFERA, VALENCIA - NORTHERN LAPWING (Vanellus vanellus)


The Northern Lapwing is a medium-sized wader bird known for its long, black crest, iridescent green back, and a "pee-wit" call. It lives in open habitats like wetlands and grasslands, feeding on invertebrates like worms and insects. They build ground nests and are known for their unique hunting technique of quickly moving, stopping, and listening for prey.

Physical characteristics Size: Approximately \(30\) cm (\(12\) inches) long with a wingspan of \(67-87\) cm (\(26-34\) inches).

Crest: A distinctive, long, wispy crest adorns the head, though it is shorter in females and juveniles.Plumage:Back is iridescent green with metallic reflections.Underparts are black and white.Males have more distinct black and white markings on the head and breast than females.Bill: Short and straight, with a black color.Legs: Long and pinkish.


Habitat and diet Habitat: Prefers open, grassy environments such as pastures, farmlands, and wetlands. They can also be found in wastelands.

Diet: Primarily carnivorous, feeding on terrestrial invertebrates like earthworms, molluscs, insects, and spiders. They also consume a small amount of plant matter. 

Behavior and reproduction Behavior: They are known for a peculiar hunting technique of running, stopping to listen and look for prey, and repeating the process. They are also gregarious and can be very territorial when nesting.

Vocalization: Vocal during the breeding season, producing a loud, shrill "pee-wit" call (which gives them the alternative name "peewit"), and a wheezy "pee-wit, wit wit, eeze wit" during their display flight.

Nesting: Nests on the ground, with both parents defending the nest aggressively.


Reproduction: Typically lay a single clutch of \(3-4\) eggs, usually between March and June.Chicks: Are precocial, meaning they can walk shortly after hatching, and are able to swim within \(24\) hours.

Lifespan: Can live to be approximately \(16\) years old, with breeding typically starting at age two. Conservation status and threats Threats: Modern farming practices that have led to the loss of suitable nesting and feeding habitats.

Predators: Predators are a major threat, especially to nests and young chicks. Mammals are the biggest threat to chicks.Conservation efforts: Some groups are working with farmers to create safe nesting areas by leaving certain plots unplanted and free of fertilizers and pesticides.

Both sexes have a prominent black malar stripe, bright yellow cere, feet, and eye-ring, with dark toenails, bill, and iris.


The common kestrel favors open habitats such as fields, heaths, shrubland, and marshland. It does not require woodland but needs alternative perching and nesting sites like rocks or buildings. It thrives in treeless steppes and can adapt to human settlements and various landscapes, from wetlands to arid savannas.

This species has a vast range, being widespread in Europe, Asia, and Africa, and occasionally reaching the east coast of North America. It has colonized some oceanic islands, though vagrant individuals are generally rare.


The common kestrel is diurnal and can be sedentary or migratory, depending on the region. It is known for its characteristic hunting behavior, hovering 10-20 meters above the ground before diving steeply onto prey. It is also capable of seeing ultraviolet light, which aids in detecting the urine trails of small mammals.

Breeding occurs in spring or the start of the dry season, with the kestrel preferring cavity nests in cliffs, trees, or buildings. Clutches typically consist of 3-7 eggs, which are incubated by both parents. The young fledge after 4-5 weeks and stay with the family for a short period thereafter.


The lesser kestrel and American kestrel are similar but not closely related. The lesser kestrel lacks black on the upperside except for wing and tail tips, while the American kestrel has much grey in the wings of males.

The common kestrel's diet consists almost exclusively of mouse-sized mammals, such as voles, shrews, and true mice. It may also consume small birds, particularly during the summer when fledglings are abundant. Invertebrates and arthropods can be significant food sources seasonally.

20-4-2018 OKAVANGO DELTA, BOTSWANA - VERVET MONKEY (Chlorocebus pygerythrus)


The Vervet monkey (Chlorocebus pygerythrus) is an Old World monkey native to Africa. The term "vervet" is also used to refer to all the members of the genus Chlorocebus. These adorable monkeys live in social groups and involve their communication and alarm calls, specifically in regard to kin and group recognition, and particular predator sightings.

The Vervet monkey is of medium to large size and has a black-tipped tail which is often longer than its body. Its fur is olive or gray, lighter on the underside. Its hands and feet are black, as are its ears and face. Its face has a white band above it, framed with white cheek tufts. Its arms and legs are long, about the same length as each other, to enable the monkey to walk with ease on all fours while on the ground, and this actually makes it quite speedy when running. The males tend to be bigger than the females.

31-12-2018 ADOR CAMPO, VALENCIA - MEDITERRANEAN PALE GLOW-WORM (Nyctophila reichii)


Nyctophila reichii, commonly known as the Mediterranean firefly, is a species of firefly. The species is very common in the southern and eastern part of the Iberian Peninsula.

Fireflies are insects of the order Coleoptera, that is, of the group of beetles, and of the family Lampyridae, whose members have the remarkable characteristic of emitting light from the end of the abdomen by means of a chemical reaction. This luminescence that we see as small points of light on summer nights has the function of sexual attraction.


Nyctophila reichii, the Mediterranean firefly, is the most common species of firefly in the Bages region. Like other fireflies, Nyctophila reichii has a very marked sexual dimorphism; males and females would be considered different species if they were not seen copulating (in image 5a).

Adult females - in images 1 and 2 - are much larger than males; they have a large, swollen abdomen, about 4 cm long, light in colour with a pinkish tinge, short elytra that do not quite cover the abdomen, vestigial wings that are not used for flight and the pronotum forming a pinkish growth on the head. At night, females emit a cold, greenish light through the luminescent organs located on the ventral side of the last three abdominal segments, in order to attract a male. Females often adopt a contorted posture with the tip of the abdomen pointing upwards so that the luminescence is more visible.

The males - in images 3 and 4 - are much smaller, about 15-18 mm; they have the appearance of a typical beetle with well-developed elytra covering the abdomen and membranous wings that allow it to fly. The males of the Mediterranean firefly do not emit luminescence.

The larvae are dark and segmented, with the sides of the body red (photos 6, 7, 8 and 9). Both in the larval and adult stages, fireflies are specialized predators in the capture of snails and slugs. Image 6 shows a Nyctophila reichii larva devouring a dune snail ( Theba pisana ) .

30-12-2018 ADOR CAMPO, VALENCIA - LITTLE OWL (Athene noctua)


The Little Owl, Athene noctua, is a diminutive yet distinctive bird, often associated with the goddess Athena in Greek mythology and Minerva in Roman lore. This bird is characterized by a flat-topped head, a robust, compact body, and a relatively short tail. Its plumage is a mottled greyish-brown, adorned with white spots, streaks, and bars, giving it a cryptic appearance. Both sexes are similar in size, measuring approximately 22 cm in length with a wingspan of 56 cm, and weighing around 180 grams.

The Little Owl possesses a large head, elongated legs, and striking yellow eyes. Its white "eyebrows" lend it a somewhat stern expression. Juvenile birds are somewhat duller than adults and lack the white crown spots. The species is known for its woodpecker-like bounding flight. During the moult, which occurs from July to November, males begin shedding feathers before females.


This owl favors open countryside and thrives in a variety of habitats, including agricultural lands with hedgerows and trees, orchards, woodland edges, parks, gardens, steppes, and semi-deserts. It can also be found in treeless areas such as dunes, and near human-made structures like ruins and quarries.

The Little Owl's range spans much of temperate and warmer parts of Europe, the Palearctic east to Korea, and North Africa. It has been introduced to Britain and the South Island of New Zealand, where it has established populations.

The Little Owl is known for its territorial nature, with males defending their territories from intruders. It is partly diurnal and can often be seen perched in prominent positions during the day. Its diet consists of insects, earthworms, other invertebrates, and small vertebrates. The owl is adept at swooping down on prey from its perch and is known to cache surplus food.


The Little Owl's call is a querulous "kiew, kiew," and it also produces various whistling or trilling sounds. During the breeding season, it may emit more modulated calls, and pairs can engage in duets. Near the nest, the owl may make yelping, chattering, or barking noises.

Breeding season sees increased vocal activity at night in late spring. Nests are located in a variety of places, including tree holes, cliffs, and old buildings. The female lays a clutch of about four eggs, which she incubates. The male provides food during this period, and both parents feed the chicks once hatched. Young owls fledge at about seven weeks of age.

The Little Owl can be confused with other small owl species, but its distinctive "eyebrows," yellow eyes, and flight pattern help differentiate it.

The Little Owl's diet is diverse, including mammals like mice and voles, birds, and a wide range of insects. It hunts both on the ground and in flight, and food caching behavior has been observed.

Conservation Status
The International Union for Conservation of Nature (IUCN) has classified the Little Owl as "Least Concern" due to its extensive range and large overall population, which appears to be stable.

30-12-2018 POTRIES, 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.

30-12-2018 POTRIES, VALENCIA - COMMON CHAFFINCH (FEMALE) (Fringilla coelebs)


The Eurasian chaffinch, or simply the chaffinch (Fringilla coelebs), presents a striking dichotomy in plumage between the sexes. The male is resplendent with a blue-grey cap and rust-red underparts, while the female's attire is more subdued, though both genders boast two white wing bars and white sides to their tails. The male's robust voice is a herald of spring, as he sings from exposed perches to court a mate.

To identify the male chaffinch, look for the black forehead, blue-grey crown, and rust-red breast, which fades to a pale creamy-pink on the belly. The wings feature a white panel on the coverts and a buff-white bar on the secondaries and inner primaries. Females and juveniles are more muted with grey-brown shades above and paler below, but retain the distinctive wing markings.

Chaffinches favor wooded environments, thriving in areas where the July isotherm ranges from 12 to 30°C. They are adaptable, however, and can be found in a variety of forested landscapes across their range.

This small passerine bird is widespread across Europe and parts of Asia, extending to Siberia. It is also an introduced species in some regions, such as New Zealand and South Africa.


Chaffinches are gregarious outside the breeding season, forming flocks in open countryside. They exhibit partial migration, with birds in colder regions moving south for the winter, while those in milder areas may remain sedentary.

The male chaffinch's song is a delightful mix of trills and chirps, with regional dialects adding to the chorus. Each male typically has a repertoire of two or three song types.

Monogamous by nature, chaffinches breed once they reach one year of age. The female meticulously constructs a nest in the fork of a tree, laying a clutch of 4-5 eggs that hatch in about 13 days. The fledglings take to the wing approximately 14 days later but continue to receive parental care for several weeks thereafter.

During the breeding season, chaffinches forage in trees for invertebrates, particularly caterpillars, to feed their young. Outside this period, their diet shifts to seeds and plant material found on the ground.

With its large numbers and expansive range, the Eurasian chaffinch is classified as of Least Concern by the International Union for Conservation of Nature. There is no evidence of significant population declines at present.

27-12-2018 OLIVA MARJAL, VALENCIA - COMMON CHIFFCHAFF (Phylloscopus collybita)


The Common Chiffchaff, Phylloscopus collybita, is a diminutive and sprightly leaf warbler known for its distinctive, onomatopoeic song. This small, migratory passerine is characterized by its greenish-brown upperparts and off-white underparts, with a weight ranging from 6 to 8 grams and a length of 10-12 centimeters.

In the field, look for the Common Chiffchaff's short whitish supercilium, fine dark bill, and dark legs. Its primary projection is short, and the plumage may appear duller and browner as it wears. Juveniles are browner above with yellow-white underparts, but they soon acquire brighter plumage after their first moult.


The Common Chiffchaff breeds in open woodlands with a mix of taller trees and ground cover across northern and temperate Europe, Asia, and parts of north Africa. It prefers woodland with trees at least 5 meters high and an undergrowth of grasses and nettles.

This species has a vast breeding range, extending from Europe to eastern Siberia and northward to about 70 N. It winters in southern and western Europe, southern Asia, and north Africa. The Common Chiffchaff is one of the earliest spring migrants to return to its breeding grounds and one of the last to depart in autumn.


The male Common Chiffchaff is fiercely territorial during the breeding season, defending its core territory against rivals. It exhibits a fearless nature, even attacking predators that threaten its nest. Outside the breeding season, these birds may form small flocks with other warblers.

The Willow Warbler and Bonelli's Warbler are similar species but can be differentiated by their longer primary projection, sleeker appearance, and different vocalizations. The Iberian Chiffchaff, once considered a subspecies, is now treated as a separate species due to differences in song, morphology, and genetics.


The Common Chiffchaff is insectivorous, feeding on a variety of insects and other small invertebrates. It is known to be an active forager, often seen flitting through foliage or hovering briefly to snatch prey.

The Common Chiffchaff is classified as "Least Concern" by the IUCN, with an extensive range and large population. While one subspecies is likely extinct, the overall species does not face significant threats at present, and populations in some areas are increasing.
