10-2-2016 MONTE CORONA, VALENCIA - BUFF TAILED BUMBLE BEE (Bombus terrestris)


Bombus terrestris, the buff-tailed bumblebee or large earth bumblebee, is one of the most numerous bumblebee species in Europe. It is one of the main species used in greenhouse pollination, and so can be found in many countries and areas where it is not native, such as Tasmania.[2] Moreover, it is a eusocial insect with an overlap of generations, a division of labour, and cooperative brood care. The queen is monogamous which means she mates with only one male. B. terrestris workers learn flower colours and forage efficiently.

B. terrestris is most commonly found throughout Europe and generally occupies temperate climates. Because it can survive in a wide variety of habitats, there are populations in the Near East, the Mediterranean Islands, and Northern Africa as well.[6] Additionally, it has escaped captivity after being introduced as a greenhouse pollinator in countries where it is not native, so this bee is now considered an invasive species in many of these places, including Japan, Chile, Argentina, and Tasmania. Nests are usually found underground, such as in abandoned rodent dens. Colonies form comb-like nest structures with egg cells each containing several eggs. The queen will lay egg cells on top of one another. Colonies produce between 300 and 400 bees on average, with a large variation in the number of workers.

2-6-2017 MONTE CORONA, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)


The house sparrow (Passer domesticus) is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of 16 cm (6.3 in) and a mass of 24–39.5 g (0.85–1.39 oz). Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus Passer, the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird.
The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, polar regions, and hot, dry deserts far away from human development. For sustenance, the house sparrow routinely feeds at home and public bird feeding stations, but naturally feeds on the seeds of grains, flowering plants and weeds. However, it is an opportunistic, omnivorous eater, and commonly catches insects, their larvae, caterpillars, invertebrates and many other natural foods.

4-6-2017 MONTE CORONA, VALENCIA - EURASIAN COLLARED DOVE (Streptopelia decaocto)


The Eurasian collared dove, also known as the collared dove or Turkish dove (Streptopelia decaocto), is a bird of modest size, presenting a grey-buff to pinkish-grey plumage that is slightly darker above than below. It is recognized by its distinctive black half-collar edged with white on its nape, from which it derives its name. The species exhibits a blue-grey underwing patch and a tail that is grey-buff above, with dark grey and white-tipped feathers below. The sexes appear similar, with juveniles displaying a less developed collar and a brown iris.

To identify the Eurasian collared dove, look for its medium size, slimmer and longer-tailed body compared to a rock pigeon, and a shorter stature than the wood pigeon. The red legs, black bill, and red iris surrounded by a small area of bare skin, which may appear white or yellow, are key features. The bird's song, a three-part cooing "goo-GOO-goo," and a harsh screeching call are also distinctive identifiers.


This species is often found in proximity to human habitation, particularly where food is plentiful and trees are available for nesting. It is not uncommon to see these doves frequenting bird tables and farms.

Originally from warm temperate and subtropical Asia, the Eurasian collared dove has expanded its range dramatically, colonizing colder countries and becoming a permanent resident in many. Its range now includes Europe, North America, and the Caribbean.

The Eurasian collared dove is known for its dispersive nature rather than migratory habits. It is a monogamous bird that shares parental duties and can breed throughout the year when food is abundant. The male performs a ritual flight during courtship, and the species can produce several broods annually.


The Eurasian collared dove's song is a distinctive "goo-GOO-goo," while its call is a harsh screech lasting about two seconds, often heard in flight before landing.

Breeding occurs close to human settlements, with nests typically within 1 km of inhabited buildings. The female lays two white eggs, which are incubated by both parents. Breeding can happen year-round in favorable conditions.

The diet of the Eurasian collared dove consists mainly of grain, seeds, shoots, and insects. They are gregarious and can form sizeable flocks in winter around food sources.

The Eurasian collared dove is currently listed as Least Concern on the IUCN Red List, indicating it is not at immediate risk of population decline. However, its invasive status in North America is a cause for ecological concern, as it may out-compete native species and potentially spread diseases to domestic poultry and other birds.

4-6-2017 MONTE CORONA, 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.


The average wingspan of both males and females is 5.1 cm (2 in), although males tend to be slightly smaller than females. Furthermore, males possess a row of grayish-brown scent scales on their forewings that is absent in the females. Females have brighter and more distinct markings than males. The subspecies P. a. tircis is brown with pale yellow or cream spots and darker upperwing eyespots. The subspecies P. a. aegeria has a more orange background and the hindwing underside eyespots are reddish brown rather than black or dark gray. The two forms gradually intergrade into each other. Subspecies P. a. oblita is a darker brown, often approaching black with white rather than cream spots. The underside of its hindwings has a marginal pale purple band and a row of conspicuous white spots. The spots of subspecies P. a. insula are a tawny orange rather than a cream color. The underside of the forewings has patches of pale orange, and the underside of the hindwing has a purple-tinged band. Although there is considerable variation with each subspecies, identification of the different subspecies is manageable.

4-6-2017 MONTE CORONA, VALENCIA - ANGLE MOTH (Ortaliella perspersata)


The Angle Moth (Ortaliella perspersata) is a species of insects with 118 observations.

4-6-2017 MONTE CORONA, VALENCIA - SPANISH GATEKEEPER BUTTERFLY (Pyronia bathseba)


Pyronia bathseba, the Spanish gatekeeper, is a butterfly of the family Nymphalidae. It is found on the Iberian Peninsula and in France, Morocco, and Algeria. A similar gatekeeper species is Pyronia tithonus, which is found in northern Europe.

The wingspan is 18–19 mm. The butterfly is on wing from May to July depending on the location.

The larvae feed on Poaceae species, mainly Brachypodium species.


A lovely species with very smart underside hindwing markings.

Its distribution & Flight patern is  North Africa, Iberian peninsula and Mediterranean France. April to July. Can be found in early May in south France at sea level and early July in Morocco at 2200m.

Its Habitat consists of Grassy rocky places usually amongst dry scrub. Generally skulks low down amongst the entwined twigs and branches of scrub and grasses. I've found it on a beach where the only grasses to be found were amongst low scrub that was stabilising the dunes. Frequently hides from the sun by resting low in bushes or below tufts of grass.

25-5-2015 GENOVES, VALENCIA - OLD WORLD SWALLOWTAIL BUTTERFLY (Papilio machaon)


Papilio machaon, the Old World swallowtail, is a butterfly of the family Papilionidae. The butterfly is also known as the common yellow swallowtail or simply the swallowtail (a common name applied to all members of the family, but this species was the first to be given the name). It is the type species of the genus Papilio. This widespread species is found in much of the Palearctic (it is the only swallowtail in most of Europe) and in North America.

This species is named after Machaon (Ancient Greek: Μαχάων, romanized: Makháōn) a figure in Greek mythology. He was a son of Asclepius.

Papilio machaon was named by Carl Linnaeus in the 10th edition of Systema Naturae in 1758, alongside nearly 200 other species of butterfly. Later, Pierre André Latreille designated it as the type species of the genus Papilio. The specific epithet machaon refers to Machaon, son of Asclepius in the works of Homer.


28-4-2014 MARXUQUERA, VALENCIA - QUEEN OF SPAIN FRITILLARY BUTTERFLY (Issoria lathonia)


lathonia) is a butterfly of the family Nymphalidae.

This migratory species is widespread in most of Europe, in North Africa, Canary Islands, and in the eastern Palearctic realm (Central Asia, Himalayas, Baluchistan, and Western China). These butterflies live in open areas, in dry lawns, agricultural wastelands and in extensive crops at altitudes between sea level and 2700 m.

Issoria lathonia is a medium-sized butterfly with a wingspan of 38–46 millimetres (1.5–1.8 in). The wings show a deep orange-violet background, with rounded black spots arranged in regular rows and suffused with greenish gray in the females. The underside of the hindwings is decorated with large pearly nacreous spots and it is crossed by a postdiscal row of black eyespots with pearly pupils. Some pearly spots also appear at the apex of the forewings.

The caterpillar can reach a length of 35 millimetres (1.4 in). It is grayish brown, with black spots, and relatively short brown spines with white tip, and a double row of dorsal white streaks. The suspended chrysalis is dark brown, with a large white saddle-shaped stain and some smaller ones of the same color, resembling a bird's dropping.

The imago is loosely similar to Speyeria aglaja, Fabriciana adippe and Brenthis daphne, which have the same orange color on the upperside of the wings, but show different markings and spots. Moreover, the underside of the hindwings does not have the large pearly spots characteristic of the Queen of Spain fritillary.


The Queen of Spain fritillary (Issoria This species is present almost throughout the year, with three or four successive generations. The eggs are laid separately on the underside of the leaves of the host plant. The larval cycle is exceptionally short. The pupation takes place among the low vegetation, between a few leaves united by silk. This species may overwinter at all larval stages.

Adults are strong flyers and fly from March to October. The heat-dependent caterpillars feed on Viola species (wild pansy or heartsease (Viola tricolor), field pansy (Viola arvensis), Viola canina, Viola odorata, Viola calcarata, Viola lutea, Viola biflora), lucerne (Medicago sativa), borage (Borago officinalis), Anchusa, Rubus and Onobrychis species.

In the dry regions Issoria lathonia carries out a seasonal vertical migration between hardy evergreen shrubs and small trees of plains and mountain fir pines, where it remains in summer to descend in autumn at low altitude.

3-6-2017 VILLALONGA RESERVOIR, VALENCIA - GREY HERON (Ardea cinerea)


Grey Herons are unmistakeable – tall, with long legs, a long beak and grey, black and white feathering. They can stand with their neck stretched out, looking for food, or hunched down with their neck bent over their chest.

The Grey Heron is a distinctive species with grey, black, and white plumage. It is often seen along rivers or lake margins, or standing in flooded fields.

In flight their large size, impressive wingspan, long legs, and folded neck give them an unmistakable silhouette. Largely silent away from colonies, flight is sometimes accompanied by a harsh ‘kraank’ call.

Grey Herons gather to nest in treetop sites called heronries, some of which have been occupied for many decades. These have been monitored in the UK since 1928 through the Heronries Census. Overall the UK's breeding population has increased, with numbers peaking in the early 2000, but with some more recent declines.

3-6-2017 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).

8-5-2017 ARCOS DE FRONTERA, ANDALUSIA - SPOTTED OWL (Strix occidentalis)


The Spotted Owl, Strix occidentalis, is a medium-sized owl with a heart-shaped face and no ear tufts. It has a rounded head and a short, square tail. The plumage is mottled with dark brown and white spots, giving it excellent camouflage against the bark of trees. This owl is a true denizen of the forest, relying on the complex structure of old-growth habitats.

Adult Spotted Owls typically measure around 43 cm in length, with a wingspan of 114 cm, and weigh approximately 600 grams. Their eggs are white and smooth, with a slightly grainy texture, measuring just over 50 mm in length. To distinguish them from the similar Barred Owl, look for the Spotted Owl's characteristic cross-shaped markings on the underparts, as opposed to the Barred Owl's alternating bars and streaks.

The Spotted Owl inhabits a variety of forest types, showing a preference for closed-canopy, uneven-aged, late-successional, and old-growth forests. The Mexican subspecies also utilizes chaparral and pinyon woodlands, including steep-walled canyons with sparse canopy cover.

Three subspecies of the Spotted Owl are distributed from British Columbia to Mexico. The Northern Spotted Owl ranges from southwestern British Columbia through parts of California, while the California Spotted Owl's range extends further south. The Mexican Spotted Owl is found in disjunct populations across the Southwestern US and into western Mexico.


Spotted Owls are nocturnal and exhibit a sit-and-wait hunting strategy, often swooping down on prey from a perch. They are monogamous and exhibit high site fidelity, with some pairs using the same nesting sites repeatedly. These owls do not breed every year, and juveniles typically disperse in late summer to fall.

The Spotted Owl's vocalizations include a series of hoots, often described as haunting and ethereal, which can carry through the dense forest they call home.

Breeding season spans from early spring to late summer or fall. Spotted Owls do not construct their own nests but use tree cavities or abandoned nests of other birds. Clutch size is usually two eggs, but can occasionally be as many as four.

The Barred Owl (Strix varia) is the most similar species, being larger and grayer with different breast patterning. Hybridization with Barred Owls has resulted in "sparred owls," which are interspecific hybrids.

The Spotted Owl's diet primarily consists of small mammals and birds. Prey items include flying squirrels, woodrats, deer mice, pocket gophers, voles, hares, rabbits, and various species of squirrels. They also consume bats, birds, amphibians, reptiles, and insects to a lesser extent.

The Spotted Owl is classified as Near Threatened, with a decreasing population trend. Habitat loss and competition with the Barred Owl are significant threats. The Northern and Mexican subspecies are listed as threatened under the Endangered Species Act, with the California Spotted Owl proposed for listing. Conservation efforts include habitat protection and management, as well as experimental removal of competing Barred Owls.

8-5-2017 ARCOS DE FRONTERA, ANDALUSIA - RED TAILED HAWK (Buteo jamaicensis)


The Red-tailed Hawk (Buteo jamaicensis) is a robust bird of prey, one of the most familiar hawks in North America. This species exhibits a broad range of plumage variations, with 14 recognized subspecies differing in color and range. The Red-tailed Hawk is a large raptor, weighing between 690 to 1,600 grams (1.5 to 3.5 pounds), with a length of 45–65 centimeters (18–26 inches) and a wingspan of 110–141 centimeters (3 feet 7 inches – 4 feet 8 inches). Females are typically about 25% heavier than males. The species is known for its brick-red tail, which gives it its common name.

Adult Red-tailed Hawks have a rich brown upper body and pale underparts, with a streaked belly and a dark bar between the shoulder and wrist. The tail is usually a rich red color above and pale below, with a black subterminal band. Immature birds have a brown tail with dark bars and may lack the red coloration. The bird's beak is short and dark, and the legs and feet are yellow. In flight, the broad, rounded wings and short, wide tail are characteristic.

Red-tailed Hawks are highly adaptable and can be found in a variety of habitats, including deserts, grasslands, forests, agricultural fields, and urban areas. They prefer open areas with high perching sites from which they can survey their territory.

This species has a vast range, breeding from Alaska and northern Canada down through the United States to Panama and the West Indies. It is absent from the high Arctic and the most densely forested parts of the Amazon.

25-6-2014 PEGO MARSHES, ALICANTE - EUROPEAN MOORHEN (JUVENILE) (Gallinula chloropus)


2-6-2017 MONTE CORONA, VALENCIA - SARDINIAN WARBLER (MALE) (Sylvia melanocephala)


The Sardinian warbler, Curruca melanocephala, presents itself as a charming and distinctive bird of the Mediterranean. The males are adorned with a sleek grey back and pristine whitish underparts, crowned with a striking black head, a pure white throat, and captivating red eyes. The females, on the other hand, exhibit a more subdued palette, with brown upperparts and buff underparts, complemented by a subtle grey head.

When attempting to identify the Sardinian warbler, look for the male's black head and red eyes, which contrast with the white throat and grey back. Females can be recognized by their brown and buff coloration with a greyish head. The variability in plumage, including the presence or absence of a reddish hue, can be a helpful clue in distinguishing between subspecies.

This typical warbler favors open landscapes and cultivated areas, where it can find bushes suitable for nesting. Its preference for such environments makes it a familiar sight in the Mediterranean countryside.

The Sardinian warbler is a resident of the southernmost regions of Europe, extending its range into Asia in Turkey and the eastern Mediterranean. While not extensively migratory, some individuals do venture to North Africa for the winter, and the species has been known to appear as a vagrant as far as Great Britain.


This species is known for its affinity for open and cultivated areas with ample shrubbery for nesting. The Sardinian warbler constructs its nest in low shrubs or brambles, where it lays a clutch of 3-6 eggs. Its diet is primarily insectivorous, but it will not shy away from indulging in berries and other soft fruits.

The Sardinian warbler's song is a rapid and rattling melody, a sound that has become synonymous with the Mediterranean landscapes where it thrives.

The breeding habits of the Sardinian warbler involve the construction of nests in low shrubbery, where the female lays a clutch of eggs that both parents will tend to.

The Sardinian warbler is part of a superspecies complex, which includes Menetries's warbler and the eastern subalpine warbler. These species share certain characteristics, such as white malar areas and light throats in males, but can be differentiated by other plumage features and their distinct calls.

Primarily insectivorous, the Sardinian warbler supplements its diet with berries and other soft fruits, particularly when insects are less abundant.

The Sardinian warbler is currently listed as Least Concern by the IUCN, indicating that, for now, this species does not face any imminent threats to its survival.

2-6-2017 MONTE CORONA, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)


The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.

Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.

The house sparrow is highly adaptable and can thrive in both urban and rural environments. It is commonly found in close association with human habitation and avoids dense forests, grasslands, polar regions, and deserts far from human development.

Native to Europe, the Mediterranean Basin, and much of Asia, the house sparrow has been introduced to various regions worldwide, including parts of Australasia, Africa, and the Americas, making it one of the most widely distributed wild birds.


House sparrows are social birds, often seen in flocks. They exhibit a range of behaviors, including dust or water bathing and communal roosting. Males are known to be territorial around their nesting sites.

The house sparrow's vocalizations are predominantly variations of a simple chirping call. Males may sing or give an "ecstatic call" during the breeding season, and the species uses a variety of calls for different social interactions.

House sparrows are generally monogamous and may mate for life. They can breed in the season following their hatching and often produce multiple clutches per year, with each clutch containing up to five eggs. Nest sites are varied, with a preference for cavities.

The house sparrow can be confused with other seed-eating birds, such as the Eurasian tree sparrow, which has a chestnut crown and a black cheek patch.

An opportunistic feeder, the house sparrow's diet consists mainly of seeds from grains and weeds, but it also consumes insects and other invertebrates, especially during the breeding season when feeding young.

Despite its widespread distribution and abundance, the house sparrow has experienced declines in some areas. However, it is currently listed as Least Concern on the IUCN Red List.

2-6-2017 MONTE CORONA, VALENCIA - SPECKLED WOOD BUTTERFLY (Pararge aegeria)


Occurs in woodland, gardens and hedgerows. Butterflies often perch in sunny spots, spiralling into the air to chase each other.

The aptly named Speckled Wood flies in partially shaded woodland with dappled sunlight. The male usually perches in a small pool of sunlight, from where it rises rapidly to intercept any intruder. Both sexes feed on honeydew in the treetops and are rarely seen feeding on flowers, except early and late in the year when aphid activity is low.

The range of this butterfly contracted during the late nineteenth and early twentieth centuries but has spread back since the 1920s. It has continued to spread over the past two decades, recolonizing many areas in eastern and northern England and Scotland.


Speckled wood (Pararge aegeria) Understated yet headstrong, the speckled wood spends its time basking in sun-dappled woodland and fiercely patrolling its patch. The pupa is well disguised as a leaf. The speckled wood usually feeds on aphid honeydew, but can feed on fruit.

In Europe there are two main subspecies of Speckled Wood. In the UK we get the paler tircis which is largely found NE of a line from southern England down to the Aegean. SW of this line is the orangey aegeria, with intermediate forms along the transition line including a subspecies endemic to the Isles of Scilly called insula. In warmer years we get more orangey individuals in the UK, so its likely temperature plays a role in this distribution. There is a fourth subspecies found in western Scotland, P. a. oblita.

1-4-2017 MIAMI, FLORIDA - TUFTED TITMOUSE (Baeolophus bicolor)


The Tufted Titmouse, Baeolophus bicolor, is a small, charismatic songbird of North America, belonging to the tit and chickadee family, Paridae. It is easily recognized by its grey upper body, white front, and rust-colored flanks. A distinctive black forehead and a tufted grey crest adorn its head, adding to its spirited appearance.

Adult Tufted Titmice measure between 5.5 to 6.3 inches in length, with a wingspan ranging from 7.9 to 10.2 inches, and weigh between 0.6 to 0.9 ounces. Males are generally larger than females. Juveniles may be identified by their less pronounced black forehead, which can lead to confusion with the Oak Titmouse in areas where their ranges do not overlap.


This species thrives in a variety of wooded environments, including deciduous and mixed forests, as well as human-altered landscapes such as gardens, parks, and shrublands.

Originally native to the Ohio and Mississippi River basins, the Tufted Titmouse has expanded its range due to factors such as the provision of bird feeders. It is now found across the United States and into parts of Ontario and Quebec in Canada. This bird is non-migratory, remaining in its territory year-round.


The Tufted Titmouse is an active forager, often seen gathering food from the ground and tree branches. It consumes a varied diet of berries, nuts, seeds, small fruits, insects, and other invertebrates, with caterpillars being a significant component during the summer months. It is known to visit bird feeders, typically grabbing a seed and retreating to cover to eat. This bird exhibits a notable curiosity towards humans and may investigate human structures in search of prey.

The song of the Tufted Titmouse is a clear, whistled "peter-peter-peter," which can vary in up to 20 notable ways. They are vocal birds, often responding to the sounds of agitation in other birds and forming mixed-species foraging flocks.


Nesting occurs in tree cavities, including natural holes, old woodpecker nests, or human-made nest boxes. Nests are lined with soft materials, and occasionally, snake skin sheds are used as a deterrent to predators. Eggs are white or cream with brownish or purplish spots, and the clutch size averages five to seven eggs. Offspring may stay with their parents through the winter and sometimes assist in raising the next year's brood.

The Tufted Titmouse's diet is diverse, including berries, nuts, seeds, insects, and other small invertebrates. It is a common visitor to bird feeders, where it exhibits a pattern of taking a seed and flying to cover to consume it.

The Tufted Titmouse has experienced a population increase of more than 1.5% per year from 1966 to 2015 in the northeastern U.S. The current breeding population is estimated at around 8 million individuals, and the species is classified as Least Concern by the IUCN.

2-6-2017 MONTE CORONA, VALENCIA - COMMON DARTER DRAGONFLY (FEMALE) (Sympetrum striolatum)


The common darter (Sympetrum striolatum) is a dragonfly of the family Libellulidae native to Eurasia. It is one of the most common dragonflies in Europe, occurring in a wide variety of water bodies, though with a preference for breeding in still water such as ponds and lakes. In the south of its range adults are on the wing all year round.

Sympetrum species are not easy to tell apart and in most areas more than one Sympetrum species will occur. Females and teneral individuals have light yellow thorax and abdomen. Males turn red as they mature. Females darken with age, becoming a dark chocolate brown, and sometimes develop a blue colouration to the bottom of the abdomen. The wings also develop a brown tinge with age. In all cases the legs have a cream or yellow stripe on a black background - this is a diagnostic feature of this species. The pterostigma of the females can be red, blue, pale blue or brown.

Adults can be seen on the wing all year round in southern Europe but in northern regions they occur from June to November.


This small dragonfly is seen in a wide variety of habitats, including lakes, ponds, canals and slow-flowing rivers. They are ambush predators, waiting on a prominent perch - such as a leaf or the top of a gate, until prey fly past, whereupon they will fly after it. They are territorial on breeding waters, often attempting to chase much bigger dragonflies away such as southern hawkers. This habit of repeatedly returning to a sunny spot allows you to easily predict where they are going to land, which is why it is one of the easiest dragonflies to photograph.

In suitable hunting areas away from water, however, they are not territorial: large numbers may assemble - groups of several hundred in a single field have been recorded - and lines of insects can be seen along the top of field gates.

Eggs are not laid, but broadcast from the air: the male holds the female in tandem and swings her down and forward over water. At the furthest point of the arc the female releases some of her eggs to fall on the water.

1-6-2017 MONTE CORONA, VALENCIA - SPOTTED FLYCATCHER (Muscicapa striata)


Spotted flycatchers are one of our summer migrants that spend the winter in Africa. They are one of the latest migrants to reach us, with a few trickling into the country from late April and most arriving from mid-May.
Despite arriving relatively late, spotted flycatchers manage to rear two broods of young before departing at the end of August. The success of the second clutch is increased by fewer eggs being laid, meaning less mouths to fill. They will nest in gardens but the nest is usually well hidden on ledges or behind climbing plants.

Spotted flycatchers prefer large flying insects, including flies and butterflies. However, if the weather is cool and insects aren’t flying, they will take smaller invertebrates from leaves and branches. If poor weather persists, many nests fail as these smaller invertebrates tend to be eaten by the parents rather than fed to the young.


In order to reduce the chances of their invertebrate prey escaping, spotted flycatchers have a series of modified feathers, like bristles, down the sides of the bill. They have also adapted to catch stinging insects. They rub the sting end on their perch to remove it, making the prey safe to eat.

The spotted flycatcher is red listed due to its rapid and consistent population decline with an 89 per cent decrease between 1967 and 2012. Evidence suggests that this is due to poor annual survival rates of first year birds, but conditions in their wintering grounds in Africa may also have contributed to the decline.


Spotted flycatchers are fairly drab birds, with brown-grey upperparts. Below they have dull white plumage with pale streaking, and there is streaking on the head. Juveniles are similar but have pale spots on their upperparts. Despite their dull appearance, they are easy to spot as they like to perch on exposed posts or branches from which they catch their prey.

As well as looking plain, the spotted flycatcher’s song is pretty unremarkable. It is squeaky, mostly unmelodic and very soft. The squeaky part of the song is part of its territorial defence, and the more musical sequences are aimed at potential mates.

1-6-2017 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).


The Common wall gecko is a small lizard native to the western Mediterranean area of North Africa and Europe. It is commonly observed on walls in urban environments, mainly in warm coastal areas. However, the Common wall gecko can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as insect hunter. This little creature is brownish-grey or brown in color with darker or lighter spots. These colors change in intensity according to the light. When geckos are active by day their color is darker than during the night.

In Europe, Common wall geckos can be found through most of the Iberian Peninsula (except northwestern Portugal and most of northern Spain), southern France, coastal Italy, southern Slovenia, northern coastal Croatia, and southwestern parts of Greece. In North Africa, they range from northern Egypt, through northern Libya, northern and central Tunisia, and northern Algeria to most of Morocco and northwestern Western Sahara. There is an isolated introduced population in southern Western Sahara. Common wall geckos can be found in rocky areas, cliffs, rock fields, and on many construction sites, ruins, building walls, and inside houses.

26-5-2017 MARJOL DE MOROS, VALENCIA - BLUE WINGED GRASSHOPPER (Oedipoda caerulescens)


The blue-winged grasshopper, Oedipoda caerulescens, is a grasshopper in the genus Oedipoda.
This species occurs in Europe, North Africa and Asia. It was recently rediscovered in the Maltese islands.

Oedipoda caerulescens is a medium-sized grasshopper, between 15 and 21 mm for males and between 22 and 28 mm for females. The body coloration varies greatly depending on the substrate on which the animals have developed: reddish brown, gray, yellowish, or even completely dark or bright. The forewings are crossed most often by two or three pale bands, but the most striking characteristic, very visible when the insect flies away, is the bright coloration of the hind wings, a beautiful turquoise highlighted with a black marginal stripe. Furthermore, the posterior femora have a notch on their upper surface. At rest, confusion is possible with other Oedipoda species such as O. germanica.


Subspecies
Oedipoda caerulescens armoricana Sellier, 1948
Oedipoda caerulescens caerulescens (Linnaeus, 1758)
Oedipoda caerulescens nigrothoracica Görtler, 1948
Oedipoda caerulescens sulfurescens Saussure, 1884


Oedipoda caerulescens frequents dry areas with low and open vegetation: dunes, heathlands, grasslands on sand and sunlit limestone rocks. Many stations correspond to land recently used for human activities, such as coal spoil heaps, quarries and pits, the ballast of railway tracks, etc. It is exclusively a terrestrial insect, and its cryptic coloration often matches its substrate. It presses itself to the ground and remains motionless, and jumps only at the very close approach of danger. A remarkable behavior is the "hook" landing which serves to confuse potential attackers. Thus, the grasshopper lands and swings round to face the direction it has come from. The sudden disappearance of the blue hind wings of the adult makes it difficult for predators to shift quickly enough to a different kind of search to relocate the prey. The female lays her eggs in bare, dry soil. In this species, acoustic emissions are virtually nonexistent. The diet consists mainly of grasses.

31-5-2017 MARJAL DE MOROS, VALENCIA - SQUACCO HERON (Ardeola ralloides)


The Squacco Heron, Ardeola ralloides, is a diminutive member of the heron family, measuring a mere 44–47 cm in length, with a compact body of 20–23 cm and a wingspan stretching 80–92 cm. This species is adorned with a buff-brown back and, during the summer months, adults boast elongated neck feathers that add to their allure.

In the field, one may identify the Squacco Heron by its stocky build, abbreviated neck, and stout bill. Its back is cloaked in a buff-brown hue. When in flight, the heron undergoes a remarkable transformation, revealing a predominantly white plumage that contrasts starkly with its resting appearance.


The Squacco Heron favors marshy wetlands in temperate regions for its habitat, where the water is warm and inviting.

Originating from the Old World, the Squacco Heron breeds in the southern reaches of Europe and extends into the Greater Middle East. When not breeding, it migrates to winter in the African continent.


This species is migratory by nature, seeking the warmer climates of Africa to spend the winter. It is seldom seen north of its breeding grounds. The Squacco Heron has been observed as a vagrant in the Fernando de Noronha islands and, on rarer occasions, in mainland South America. It nests in modest colonies, often in the company of other wading birds, and constructs its nests from sticks on platforms in trees or shrubs.

The Squacco Heron selects freshwater locales across Europe and the Middle East to breed, later migrating southward to the Sub-Saharan African region. During the breeding season, they lay a clutch of three to four eggs.


The squacco heron is a migrant, wintering in Africa. It is rare north of its breeding range. The species has been recorded in Fernando de Noronha islands, and more rarely in mainland South America, as a vagrant. This is a stocky species with a short neck, short thick bill and buff-brown back. In summer, adults have long neck feathers. Its appearance is transformed in flight, when it looks very white due to the colour of the wings.

The squacco heron's breeding habitat is marshy wetlands in warm countries. The birds nest in small colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. Three to four eggs are laid. They feed on fish, frogs and insects.


Adept at foraging, the Squacco Heron feeds on a diet consisting of fish, frogs, and insects, making the most of its wetland environment.

The IUCN Red List currently classifies the Squacco Heron as Least Concern, indicating a stable population without immediate threats to its survival.

Non-breeding Squacco Herons share certain physical characteristics with other heron species such as the Indian Pond Heron and the Malagasy Pond Heron, including tawny plumage, lighter streaking, a smaller bill, and narrower wing tips.
