4-10-2017 PEGO MARJAL, ALICANTE - BANDED GARDEN SPIDER (Argiope trifasciata)


Argiope trifasciata (the banded garden spider or banded orb weaving spider) is a species of spider native to North and South America, but now found around the world. It can be found in certain areas of Europe, namely the Iberian Peninsula, the Canary Islands, and Madeira. The similar looking Argiope bruennichi is common in the Azores. They typically begin to appear during autumn from early September to late October as temperatures start dropping. In Egypt, the type locality of this spider, females were found surviving the relatively warm winter months.


Behavior

In Illinois, Argiope trifasciata hatches in early summer but does not become readily notable until mid-August, when they have grown large enough to make their distinctive webs, which can be up to 60 cm (24 in) in diameter, among stems and bushes. The female rests at the centre of the web facing downwards, with her legs often arranged in pairs, making a cross shape; some female spiders conceal themselves in a hidden location close to the web, being alerted to a potential victim by a non-sticky thread leading to the center. Some segments of the web often have thicker threads known as stabilimenta forming a decorative pattern. 


Male spiders are much smaller than females and have their own small webs in close proximity to the females' webs. Argiope trifasciata is diurnal, and feeds on the insects that get snared in the web. Large, powerful prey like paper wasps, are swiftly wrapped in silk to immobilise them, before being injected with toxic saliva.


Their webs can reach a diameter of about 60 cm. The length of the web depends on the size of the spider. Webs are capable of reaching a total length of two meters.


Subspecies

Argiope trifasciata deserticola Simon, 1906 (Sudan)
Argiope trifasciata kauaiensis Simon, 1900 (Hawaii)

 
The silk decorations of Argiope spiders are thought of as visual signals by researchers. Even though the purpose behind the silk decorations made by Argiope trifasciata remains uncertain, there are a few hypotheses: to make the spider appear larger and to act as a warning sign. It has been shown that webs containing stabilimenta catch fewer insects because they are less cryptic, but on the other hand these webs are less often damaged by birds flying through them.

4-10-2017 PEGO MARJAL, ALICANTE - BOOTED EAGLE (Hieraaetus pennatus)


The Booted eagle (Hieraaetus pennatus) is a small mostly migratory bird of prey with a wide distribution. Despite its small size, the Booted eagle is a fierce hunter that usually captures and kill its prey in its powerful talons.

There are two relatively distinct plumage forms of the Botted eagle. Pale birds are mainly light grey with a darker head and flight feathers. The other form has mid-brown plumage with dark grey flight feathers.


Booted eagles breed in many different regions in both the northern and southern hemisphere. These include southern Europe, North Africa, and across Asia, and also in western South Africa and Namibia. The northern populations are migratory spending November to February in Sub-Saharan Africa and South Asia, while the small southern African populations are sedentary. Booted eagles prefer to live in wooded, often hilly countryside with some open areas. They breed in rocky, broken terrain but migrants may use almost any type of habitat except the dense forest. The birds of the Palearctic breeding population usually nest in coniferous or deciduous woodlands and often in trees.


Booted eagles are active during the day and are typically seen in pairs or as solitary individuals. They fly at relatively low heights, making them conspicuous. Booted eagles typically hunt on the wing, stooping quickly with wings folded in and feet extended. They can also catch insects while walking on the ground. The common call of Booted eagles is a shrill 'kli-kli-kli'.

Booted eagles are carnivores. Their diet includes small mammals, rodents, reptiles and birds. In Southern Africa, it has been noted that birds are their most common prey.

Booted eagles are monogamous. They form strong pair bonds that last for life. With the start of the breeding season, pairs can be seen circling high above in spectacular display. Egg-laying takes place between March and June. The female lays 1-2 eggs in a nest built from sticks and lined with green leaves in a tree or on a crag, or it takes over the disused nest of another large bird such as a Black kite or Grey heron. The female incubates the egg for around 45 days and is fed by the male during this time. After hatching she guards the nest and the young while the male provides all the food. The chicks fledge after 50-55 days and continue to be fed by both parents for another 2 weeks.

2-10-2017 BARX, VALENCIA - CARDINAL BUTTERFLY (Argynnis pandora)


Argynnis pandora, the cardinal, is a butterfly of the family Nymphalidae. It is common throughout southern Europe and is also found in northern Africa and the Middle east and then east across the Palearctic to the Tian-Shan andnorthwestern India.

The butterfly flies from April to September (in Europe typically May to August) depending on the location. In Switzerland, the species is found at altitudes of up to 2600 meters. Among other habitats, it favours deciduous and open pine forests, in which there is a large supply of nectar-rich plants from the genera Cirsium , Carduus or Centaurea.

The larvae feed on Viola species.


The wingspan is 64–80 mm. A. pandora Schiff. (= cinara F., maja Cr.) (71c). The largest European Argynnis. Above stronglyre calling valesina, but brighter greenish, densely spotted with black. Beneath quite different, the apex of the forewing and the hindwing bright green, the disc of the forewing fleshy red and spotted with deep black, the hindwing with a few narrow bands, which are more white than silvery and vary strongly in number and development.In ab. dacica Horinuz., a kind of valesina-form from Roumania, the basal area of both wings darkened, contrasting with the distal area, which is slightly paler than usual. — pasargades Fruhst.[now subspeciesA. p. pasargades], from the Alexander Mts., has the whole upperside pale, especially the forewing, which has hardly a trace of green, being also paler yellow beneath, with the black markings reduced. — seitzi Fruhst.[now subspecies A. p. seitzi Fruhstorfer, 1908] (71c) has been described fromspecimens found by me [Stichel] in the Aures Mts. in Algeria.


Larger than European individuals, paler green beneath, darker greenish yellow above; the black markings more prominent and abundant, often confluent. — paupercula' Ragusa has no silvery white bands and spots; especially in the southern districts, where it is locally the prevalent form, for instance in Algeria. — Larva purplish brown, with black head, without the yellow dorsal stripe of paphia, otherwise similar to the latter, but the spines shorter; on the back of each segment a velvety black spot with 2 white dashes; until June on Viola. The species occurs particularly in the Mediterranean countries, being found in North Africa, the Canaries, Spain, South France northward to the Valais, where it approaches the German frontier, also in Italy, the south of Austria-Hungary, Turkey and Asia Minor, going eastward to the Tian-shan; plentiful in some places. The butterflies are on the wing from June onwards; their flight is fast and graceful, rushing or swimming, and they usually settle on those branches of trees which hang over the road, or on thistle-heads.

1-10-2017 MONTE CORONA, ADOR - FLESH FLY (Family Sarcophagidae)


Sarcophagidae (from Ancient Greek σάρξ sárx 'flesh' and φαγεῖν phageîn 'to eat') are a family of flies commonly known as flesh flies. They differ from most flies in that they are ovoviviparous, opportunistically depositing hatched or hatching maggots instead of eggs on carrion, dung, decaying material, or open wounds of mammals, hence their common name. Some flesh fly larvae are internal parasites of other insects such as Orthoptera, and some, in particular the Miltogramminae, are kleptoparasites of solitary Hymenoptera. The adults mostly feed on fluids from animal bodies, nectar, sweet foods, fluids from animal waste and other organic substances. Juveniles need protein to develop and may be laid on carrion, dung or sweet plant foods (including fruit, nuts, and artificial foodstuffs).Members of the subfamily Sarcophaginae are small to large flies 0.16–0.9 inches (4.1–22.9 mm) with black and gray longitudinal stripes on the thorax and checkering on the abdomen. Other key features include red eyes and a bristled abdomen. Abdominal sternites II and III are free and cover the margins of tergites. The posthumeral bristles are one or two in number, with the outermost pair missing.


The presutural bristle is located lower than the notopleural bristle, and closer to the notopleural bristle than to the outermost posthumeral bristle. The presutural bristle is located higher than or level with the posthumeral bristle. The hindmost posthumeral bristle is located even with or toward the midline from the presutural bristle. Four notopleural bristles are present and arranged in the order - short, long, short, long - from front to rear.

Vein M1 +2 (anterior transverse vein, medial vein 1+2 ) is always present, and the cubitulus is strongly bent at right angles or acute; vein Rs is dibranched.

The eyes are smooth and very rarely hairy.

Flesh flies can carry leprosy bacilli and can transmit intestinal pseudomyiasis to people who eat their larvae. Flesh flies, particularly Wohlfahrtia magnifica, can also cause myiasis in animals, mostly to sheep, and can give them blood poisoning, or asymptomatic leprosy infections.

30-9-2017 GANDIA PLAYA, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)


House sparrows have adapted conical beaks and a specialized bone in their tongues that helps them eat seeds efficiently.

House sparrows are insectivorous (insect-eating) and granivorous (grain-eating) songbirds with stout conical beaks, stubby squared-off tails, and small plump bodies.  House sparrows and Ontario’s native sparrow species belong in different families, with Ontario’s natives belonging to the Passerellidae family (new world sparrows), while house sparrows belong to the Passeridae family (old world sparrows). Native to Eurasia, northern Africa, and most of Europe, this species became invasive following their intentional release into Brooklyn in the mid-1800s as a control method to decrease linden moth populations (Barlow, 2015). Today, this avian invader has made most of North America its home.


Male and female house sparrows will typically grow to be similar sizes, with both sexes capable of reaching a body length of 15-17 cm and wingspans of 19-25 cm (The Cornell Lab of Ornithology). This species displays sexual dimorphism (sexes of the same species display different morphological characteristics); males have more vibrant and distinct colouration (specifically during breeding season), whereas females and juveniles appear more monotone and streaky brown.   

The appearance of males will vary depending on the season. Males will be the easiest to identify throughout the breeding season and display the most distinct markings and colouration, with their patterned heads being the most recognizable during this time. Breeding males have a grey-coloured crown, a rufus/chestnut brown-coloured stripe behind the eye that extends down into the nape, a black throat that sometimes extends into the upper chest, white/light grey lower chest and belly, and brown and black striping located on the wings and mantle (area between the wings on birds’ back). Breeding males will usually have a black beak.

28-9-2017 MONTE CORONA, VALENCIA - MEDITERRANEAN KATYDID (Phaneroptera nana)


The Mediterranean katydid (Phaneroptera nana) female sings in response to the male, prompting the male to move towards the female. This is unique to the species, because in other species of katydids, it is usually the female moving towards the male in response to hearing their chirps. However, because the females stay static while the males move to locate them, the females are at less risk of encountering threats and predators. However, the males will not decide to interact with a female unless they illicit a response within 60 milliseconds, ensuring that the female is close enough to them.


The females are selective of the males they respond to, and generally they prefer longer chirps. At least two chirps from the males are needed for the female to entertain the males and reply to them. However, more chirps than that from the males do not make the females more likely to duet with the males.

The female Mediterranean katydids lay their eggs in the lamina of plants. the female does this by bending her abdomen and chewing on the lamina to create an opening. The eggs she lays around 3mm in size on average. Those eggs usually hatch in summertime but that can vary. The timing means that P. nana is usually easily encountered through the summer and fall seasons.

27-9-2017 MARJAL DE MOROS, SAGUNTO - NORTHERN WHEATEAR (FEMALE) (Oenanthe oenanthe)


The northern wheatear or wheatear (Oenanthe oenanthe ) is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. It is the most widespread member of the wheatear genus Oenanthe in Europe and North and Central Asia.

The northern wheatear is a migratory insectivorous species breeding in open stony country in Europe and east across the Palearctic with footholds in northeastern Canada and Greenland as well as in northwestern Canada and Alaska. It nests in rock crevices and rabbit burrows. All birds spend most of their winter in Africa.

The northern wheatear is larger than the European robin at 14.5–16 cm (5.7–6.3 in) in length. The northern wheatear also has a wingspan of 26– 32 cm and weighs 17-30 g.

Both sexes have a white rump and tail, with a black inverted T-pattern at the end of the tail.

The plumage of the summer male has grey upperparts, buff throat and black wings and face mask. In autumn it resembles the female apart from the black wings. The female is pale brown above and buff below with darker brown wings. The male has a whistling, crackly song. Its call is a typical chat chack noise, and the flight call is the same.

28-9-2017 CAMI LES FONTS OLIVA, 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.

28-9-2017 MARJAL DE OLIVA, 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.

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

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

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

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

28-9-2017 CAMI LES FONTS OLIVA, VALENCIA - GREYLAG GOOSE (Anser anser)


The Greylag goose (Anser anser) is a large goose in the waterfowl family Anatidae. Its distribution is widespread, with birds from the north of its range in Europe and Asia migrating southwards to spend the winter in warmer places. It is the ancestor of most breeds of domestic goose, having been domesticated at least as early as 1360 BC.




The Greylag is the largest and bulkiest of the grey geese of the genus Anser, but is more lightly built and agile than its domestic relative. It has a rotund, bulky body, a thick and long neck, and a large head and bill. It has pink legs and feet, and an orange or pink bill with a white or brown nail (hard horny material at the tip of the upper mandible). The plumage of the Greylag goose is greyish brown, with a darker head and paler breast and belly with a variable amount of black spotting. It has a pale grey forewing and rump which are noticeable when the bird is in flight or stretches its wings on the ground. It has a white line bordering its upper flanks, and its wing coverts are light-colored, contrasting with its darker flight feathers. Its plumage is patterned by the pale fringes of the feathers. Juveniles differ mostly in their lack of black speckling on the breast and belly and by their greyish legs. Adults have a distinctive 'concertina' pattern of folds in the feathers on their necks.

28-9-2017 MARJAL DE OLIVA, VALENCIA - WHITE WAGTAIL (Motacilla alba)


The White Wagtail (Motacilla alba) is a small, elegant passerine bird, a member of the family Motacillidae, which includes pipits and longclaws. This slender bird measures between 16.5 to 19 cm in length, with East Asian subspecies reaching up to 21 cm. It is characterized by its long, constantly wagging tail, a behavior that has become synonymous with the genus. Weighing an average of 25 g, the White Wagtail can live up to 12 years in the wild.

Adult White Wagtails exhibit a distinctive plumage with a combination of grey, black, and white. The bird's upper parts are generally grey, with a white face, belly, and breast. Males during the breeding season may show a darker back, and the species is known for its sharp, brisk call and more melodious song during courtship.

The White Wagtail is commonly found in open country, often in close proximity to human habitation and water sources. It shows a preference for bare areas which facilitate the sighting and pursuit of prey. This bird has adapted well to urban environments, utilizing paved areas such as parking lots for foraging.

This species has a vast breeding range across Europe, the Asian Palearctic, parts of North Africa, and has a presence in Alaska. It is a migratory bird, with populations moving to Africa and parts of Asia during the winter. In Great Britain and Ireland, the darker subspecies known as the Pied Wagtail is more prevalent.

The White Wagtail is known for its perpetual tail wagging, a behavior that remains somewhat enigmatic but is thought to be a signal of vigilance to predators. It is a monogamous bird that defends its breeding territory with determination.

27-9-2017 MARJAL DE MOROS, SAGUNTO - RUDDY DARTER DRAGONFLY


The ruddy darter is to be found in temperate regions throughout Europe as far east as Siberia and as far south as the northern Sahara. Its conservation status is regarded as secure, and indeed numbers seem to be increasing in some locations such as central England.

It is present in the following countries: Albania; Algeria; Armenia; Austria; Azerbaijan; Belarus; Belgium; Bosnia and Herzegovina; Bulgaria; Croatia; Cyprus; Czech Republic; Denmark; Estonia; Finland; France; Germany; Greece; Hungary; Ireland; Italy; Kazakhstan; Kyrgyzstan; Latvia; Liechtenstein; Lithuania; Luxembourg; Macedonia, the former Yugoslav Republic of; Moldova; Monaco; Montenegro; Morocco; Netherlands; Norway; Poland; Portugal; Romania; Russian Federation; Serbia; Slovakia; Slovenia; Spain; Sweden; Switzerland; Tajikistan; Tunisia; Turkmenistan; Ukraine; United Kingdom; Uzbekistan. 

This species tends to prefer quiet bodies of water that feature semiaquatic vegetation such as rushes and reeds.

The ruddy darter can reach a body length of 34–36 millimetres (1.3–1.4 in)[3] and attains a wingspan of up to 6 cm (2.4 in). These dragonflies are smaller than the common darter. They have black legs and the wings show a brown pterostigma and an orange color at the base of the wings. Two evident black marks are located on segments S8 and S9 of the abdomen.


The head, thorax and abdomen of the mature male are vivid red, while the female is slightly smaller, and is a golden-yellow colour with black markings. The blood-red color of the males develop with maturity, together with a red frons and a red-brown thorax.  The abdomen widens for the final third of its length and shows a marked pinched section where it joins the thorax.

The all-black legs of the ruddy darter distinguish it from the otherwise very similar common darter (Sympetrum striolatum) and vagrant darter (Sympetrum vulgatum), both of which show yellow stripes on their legs. The spotted darter (Sympetrum depressiusculum) with all-black legs has noticeably more clubbed abdomen and brighter pterostigmata.

The ruddy darter can be found between the months of June and November.  Mating takes place on the wing, with the coupled pair performing a dipping flight over the water. The female jettisons her fertilised eggs at the water surface by alternating movements of the abdomen. The male may hover nearby during this period and protect the female by driving off any approaching males.

The larvae spend the year beneath the water surface before emerging and pupating into adults.

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

27-9-2017 MARJAL DE MOROS, SAGUNTO - GREATER FLAMINGO (JUVENILE) (Phoenicopterus roseus)


The greater flamingo, Phoenicopterus roseus, stands as the most widespread and largest member of the flamingo family. This majestic bird is adorned with pinkish-white plumage, save for the red wing coverts and contrasting black primary and secondary flight feathers. The bill is a striking pink with a black tip, and the legs are a uniform pink, completing the iconic look of this species.

Adult greater flamingos can be identified by their height, ranging from 110 to 150 cm, and their weight between 2 and 4 kg. The largest males can reach up to 187 cm tall and weigh 4.5 kg. Observers should note the distinctive coloration, with the majority of the body being pinkish-white, red wing coverts, and black flight feathers. The pink bill with a black tip and entirely pink legs are also key identification features. The call of the greater flamingo is reminiscent of a goose-like honking.

The pink bill with a black tip and entirely pink legs are also key identification features. The call of the greater flamingo is reminiscent of a goose-like honking.


Greater flamingos favor mudflats and shallow coastal lagoons with saline water, where they can be seen stirring the mud with their feet in search of food.

This species is common in the Old World, with a range that includes Northern and Sub-Saharan Africa, the Indian Subcontinent, the Middle East, the Levant, and Southern Europe. Notably, they are found in coastal regions and along water bodies such as the Nile River, the Persian Gulf, the Gulf of Aden, the Red Sea, and the Mediterranean.

Greater flamingos are social birds, often found in large flocks. They feed with their heads down, filtering out sustenance from the water with their specially adapted bills. During the breeding season, these birds engage in a fascinating display of spreading uropygial secretions over their feathers to enhance their color, a behavior likened to applying "make-up."

The vocalization of the greater flamingo is a distinctive honking, similar to that of a goose, which can be heard over considerable distances.

The species lays a single chalky-white egg on a mud mound, a typical breeding behavior for flamingos.


While similar to the American flamingo, the greater flamingo can be distinguished by differences in head, neck, body, and bill coloration.

Greater flamingos feed on a diet that includes small shrimp, seeds, blue-green algae, microscopic organisms, and mollusks. They filter their food from the water with their downward-facing heads and movable upper jaws.

The IUCN Red List classifies the greater flamingo as Least Concern, indicating a stable population. However, they face threats from habitat encroachment and pollution in their water supplies.

In the voice of David Attenborough, one might say: "The greater flamingo, with its elegant stature and vibrant hues, is a testament to the wonders of the avian world. As it sifts through the shallows, one cannot help but be captivated by its grace and the delicate balance it maintains within its ecosystem."

27-9-2017 MARJAL DE MOROS, SAGUNTO - EARED GREBE (JUVENILE) (Podiceps nigricollis)


The Black-necked Grebe, also known as the Eared Grebe (Podiceps nigricollis), is a striking member of the grebe family. It is characterized by its distinctive breeding plumage, which includes a black to blackish-brown head, neck, and breast, and ochre-colored feathers that fan out behind the eyes over the ear coverts. The flanks are a rich tawny rufous to maroon-chestnut, while the abdomen remains white. In non-breeding plumage, the bird sports greyish-black upper parts and a white or whitish body. Juveniles have a browner hue in their darker areas.

To identify the Black-necked Grebe, look for the red eye with a narrow yellow ring, the blackish line extending from the gape to the eye, and the thin, upturned black bill. The subspecies californicus typically has a longer bill, while P. n. gurneyi is smaller with a greyer head and lacks non-breeding plumage.

This species favors vegetated freshwater lakes for breeding and migrates to saline lakes and coastal estuaries post-breeding.

The Black-necked Grebe has a wide distribution, breeding across parts of Africa, Eurasia, and the Americas. It winters in locations such as the southwestern Palearctic, eastern parts of Africa and Asia, southern Africa, and as far south as Guatemala in the Americas.

The Black-necked Grebe is a reluctant and inefficient flier, often avoiding flight except during migration. It can travel up to 6,000 kilometers during migration and becomes flightless for two months during the moulting period.


During the breeding season, the Black-necked Grebe emits a high-pitched "ooeek" call that ascends in pitch, used for both territorial and courtship purposes. Outside of breeding, it is generally silent.

Breeding occurs in various locations depending on the subspecies, with a floating cup nest built on open lakes. The species is socially monogamous and may lay one or sometimes two clutches of three to four eggs, with brood parasitism being common.

The Black-necked Grebe can be confused with other grebe species, but its distinctive breeding plumage and vocalizations help differentiate it.

The diet consists mainly of insects, crustaceans, molluscs, tadpoles, small frogs, and fish. It employs multiple foraging techniques, including diving, foliage gleaning, and capturing flying insects.

The IUCN classifies the Black-necked Grebe as Least Concern, with an estimated population of 3.9–4.2 million individuals. Despite potential threats like oil spills and disease outbreaks, these are not considered significant risks to the overall population.

27-9-2017 MARJAL DE MOROS, SAGUNTO - ZITTING CISTICOLA (Cisticola juncidis)


The Zitting Cisticola, or Streaked Fantail Warbler, is a diminutive bird, measuring a mere 10 to 12 centimeters in length. Its upper parts are adorned with a brown plumage, intricately streaked with black, while its underparts remain a modest whitish hue. The tail is a noteworthy feature, broad and tipped with white, and is frequently flicked—a behavior that has inspired one of the bird's colloquial names.

To identify the Zitting Cisticola, look for its rufous rump and the absence of gold on the collar. The tail, brownish with white tips, is another distinguishing characteristic. Males, during the breeding season, exhibit less crown streaking and more pronounced back markings than females, though differences between sexes are generally subtle.


The Zitting Cisticola favors grasslands as its primary habitat, often found in proximity to bodies of water.

This species boasts a broad range, encompassing southern Europe, Africa (excluding deserts and rainforests), and southern Asia, extending to northern Australia. It is largely sedentary, though certain East Asian populations undertake migrations to warmer climes in winter.


These birds are predominantly insectivorous and may be observed in small flocks. The breeding season is timed with the rains, and in many regions, the Zitting Cisticola is known to produce two broods annually. Males display polygynous tendencies, though monogamous pairings are not uncommon. The male initiates nest construction within the grasses and performs a specialized display to attract females, who then complete the nest.

The male's breeding season is marked by a distinctive flight display, punctuated by a series of "zitting" calls reminiscent of the sound of scissors snipping.


Nests are artfully constructed with living leaves woven into a soft matrix of plant down, cobwebs, and grass. The structure is cup-shaped with an overhead canopy for camouflage. Females lay 3 to 6 eggs and are solely responsible for incubation, which lasts approximately 10 days. Multiple broods may be raised in a single season.

The Zitting Cisticola can be differentiated from the Golden-headed Cisticola (Cisticola exilis) by the absence of a nuchal collar.

Their diet consists primarily of insects, which they forage for within their grassland habitats.

The Zitting Cisticola is classified as Least Concern by the IUCN, indicating a stable population without immediate threats to its survival.

27-9-2017 MARJAL DE MOROS, SAGUNTO - EURASIAN COOT (JUVENILE) (Fulica atra)



The Eurasian coot (Fulica atra), also known as the Common coot, or Australian coot, is a member of the rail and crake bird family, the Rallidae. It is found in Europe, Asia, Australia, New Zealand, and parts of North Africa. Similar-looking coot species are found throughout the world, with the largest variety of coot species living in South America.

The Eurasian coot is 36–38 cm (14–15 in) in length with a wing-span of 70–80 cm (28–31 in); males weigh around 890 g (31 oz) and females 750 g (26 oz). It is largely black except for the white bill and frontal shield (which gives rise to the phrase "as bald as a coot", in use as early as 1430). As a swimming species, the coot has partial webbing on its long strong toes. The sexes are similar in appearance.


The juvenile is paler than the adult, has a whitish breast, and lacks the facial shield; the adult black plumage develops when about 3–4 months old, but the white shield is only fully developed at about one year old.

Eurasian coots breed in Europe, Asia, Australia, and Africa. They have recently expanded their range into New Zealand. These birds are residents in the milder parts of their range only performing nomadic movements; however, populations from much of Asia migrate further south and west in winter as the waters freeze. Eurasian coots inhabit freshwater lakes, ponds, pools, creeks, rivers and river deltas, marshes, freshwater meadows, flooded grasslands, and freshwater, and saline lagoons.

22-9-2017 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 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.


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.

22-9-2017 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.

22-9-2017 MONTE CORONA, VALENCIA - SOUTHERN SKIMMER DRAGONFLY (Orthetrum brunneum)


Orthetrum brunneum, the southern skimmer, is a species of 'skimmers' belonging to the family Libellulidae.

Subspecies
Subspecies include:

Orthetrum brunneum var. brunneum (Fonscolombe, 1837) (Palearctic realm)
Orthetrum brunneum var. cycnos (Sélys, 1848) (Corsica and Sardinia) 
Distribution
This 'skimmer' is present in most of Europe and the range extends to Mongolia and North Africa.

It occurs in Afghanistan, Albania, Algeria, Andorra, Armenia, Austria, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, China, Croatia, Cyprus, Czech Republic, Egypt, France, Germany, Greece, Hungary, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Republic of Macedonia, Malta, Moldova, Montenegro, Netherlands, Poland, Portugal, Romania, Russia, Serbia; Slovakia, Slovenia, Spain, Switzerland, Turkey, and Ukraine.

This species mainly prefers small streams, canals and ditches, with shallow, fast warming water.


The adults grow up to 40–45 millimetres (1.6–1.8 in) long. Their dimensions on average are larger than in Orthetrum coerulescens.

The thorax and the abdomen are pale blue in males, yellowish-brown or greyish-brown in females. Young males are brownish. The abdomen is relatively flattened and shows a thin middorsal black line and distinct points on each segment. The wings are hyaline, with yellow or pale brown pterostigma. The wingspan reaches 66–70 millimetres (2.6–2.8 in).

Adults can be encountered from mid June through late August in the immediate vicinity of quiet rivers or close to stagnant and shallow waters, lying on a well sunny ground. Sexually mature males defend a 'territory' on the waterfront by making short inspection flights, in order to chase away other males.

These skimmers commonly mate at rest, usually on the ground. Female lays the eggs on the surface of shallow water, touching it only with her abdomen while flying, sometimes accompanied by the male, that keeps other males at a distance.

The larvae are ferocious predators. They live buried in fine soil material (fine sand, silt, etc.), in unshaded places in shallow water. They overwinter and develop in two or three years.
