8-7-2018 TABLAS DE DAIMIEL, LA MANCHA - BARN SWALLOW (Hirundo rustica)


The barn swallow (Hirundo rustica) is a migratory passerine bird, recognized as the most widespread species of swallow in the world. It is a distinctive bird with blue upperparts and a long, deeply forked tail, known for its graceful flight and agile maneuvers. The adult male of the nominate subspecies is 17–19 cm in length, including elongated outer tail feathers, and has a wingspan of 32–34.5 cm. It is adorned with a rufous forehead, chin, and throat, which are set apart from the off-white underparts by a broad dark blue breast band. The outer tail feathers are elongated, contributing to the iconic "swallow tail."

The barn swallow can be identified by its steel blue upperparts, a rufous face, and a dark blue breast band that separates the rufous from the off-white underparts. The deeply forked tail is a key characteristic, with a line of white spots across the upper tail's outer end. Females resemble males but have shorter tail streamers and less glossy blue coloring. Juveniles are browner with paler rufous faces and whiter underparts, lacking the adult's long tail streamers.

The barn swallow favors open country with low vegetation, such as pastures, meadows, and farmland, often near water. It avoids heavily wooded or steep areas and densely built-up locations. The species typically nests in man-made structures like barns and stables, or under bridges and wharves.

9-7-2018 PETROLA LAKES, ALBACETE - BLACK WINGED STILT (JUVENILE) (Himantopus himantopus)


The Black-winged Stilt, Himantopus himantopus, is a slender wader known for its strikingly long, pink legs and contrasting black-and-white plumage. This elegant bird is a member of the avocet and stilt family, Recurvirostridae.

Adult Black-winged Stilts measure 33–36 cm in length. They possess a long, thin black bill and display a distinctive black and white coloration. The head and neck are predominantly white, with variable black markings depending on the sex and subspecies. Males typically have a glossy or greenish sheen on their black backs, while females exhibit a more brownish tinge. During flight, their long legs trail behind, and their wingbeats are steady.

These birds favor marshes, shallow lakes, and ponds as their breeding grounds. They are also known to inhabit coastal areas during migration and in the winter months.

The Black-winged Stilt has a wide range, extending across Europe, Asia, and Africa. Some populations migrate to coastal regions in winter, while others in milder climates may remain resident or engage in short-range movements.

The Black-winged Stilt has a wide range, extending across Europe, Asia, and Africa. Some populations migrate to coastal regions in winter, while others in milder climates may remain resident or engage in short-range movements.


Black-winged Stilts are often seen foraging in shallow waters, gracefully picking insects and crustaceans from the surface. They are known to nest in small groups, sometimes alongside avocets, and exhibit a variety of courtship behaviors, including intricate displays and duets.

The flight call of the Black-winged Stilt is a sharp and clear kleek, typically heard during its aerial maneuvers.


Nests are simple bare spots on the ground near water. These birds are communal nesters and may breed in loose colonies. They have been known to breed as far north as Britain, with recent successful breeding events recorded in Southern and Northern England.

Their diet consists mainly of insects and crustaceans, which they deftly pick from the water's surface or from wet sand.

The IUCN lists the Black-winged Stilt as Least Concern, indicating a stable global population. However, they are protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds, highlighting the importance of international cooperation in their conservation.

9-7-2018 LAGUNA DEL REY, RUIDERA - WAVYLEAF MULLEIN (Verbascum sinuatum)


Verbascum sinuatum, commonly known as the scallop-leaved mullein, the wavyleaf mullein, or Candela regia, is a species of perennial herbaceous plants in the genus Verbascum (mullein), growing in heavy soils in Central Asia and the Mediterranean region. It grows to 1.2–1.5 m (3.9–4.9 ft). The plant has an erect inflorescence stem, and is entirely covered with stellate hairs (trichomes) which are not pleasant to the touch.

In the winter, a rosette of broad-leaves grows at the base of the Scallop-leaved mullein and spreads itself on the ground (length 30–50 cm). In the spring, a leafless stalk grows from the base of the plant, splitting into many diagonal stems that can grow as much as 50 to 100 cm. in length, on which the flowers are located. The plant bears simple, emarginate leaves, and has a yellow lamp-shaped flower (hence its name Candela) of 5 petals, blossoming mostly in late May to August, although sometimes as late as October.

The plant's leaves are alternate, rosette, entire, dentate or serrate.

The plant has a broad Irano-Turanian distribution, as well as a broad Mediterranean distribution (stretching from the Mediterranean coastal regions to West and South Iran). The plant is native to Israel, where it grows in the Golan, the Hermon, the coastline of the Mediterranean Sea, Gilboa, Carmel, Samarian Mountains, Judean Mountains, the Jordan Valley, the Sharon valley, Shephelah, Northern Negev, and Eilat Mountains, and the Arabah, typically found in waste habitats, along waysides, and in open chaparrals (shrublands) and phrygana.

9-7-2018 LAGUNA DEL REY, RUIDERA - YELLOW STAR THISTLE (Centaurea solstitialis)


Centaurea solstitialis is an annual herb from the family Asteraceae. During the vegetative stage it forms a rosette of non-spiny leaves, between 5–20 centimetres (2–8 inches) in diameter. As the summer approaches, it produces a flowering stem up to 1 metre (3+1⁄2 feet) in height. The leaves at the base are lobed and range between 5–8 cm (2–3 in) in length, while the ones on the stem are unlobed and smaller. Between May and October, the stem produces numerous spinous flower heads (capitula) about 12–16 millimetres (1⁄2–5⁄8 in) across, containing between 10–50 yellow flowers, with spines between 1–2.5 cm (3⁄8–1 in). Flowers within capitula are pollinated by insects and each capitula produces 10–50 seeds, some with and some without a pappus. It is an annual semelparous species, and will die after reproduction is completed, normally by the end of the summer.

9-7-2018 LAGUNAS DE REY, RUIDERA - ELMLEAF BLACKBERRY (Rubus ulmifolius)


Rubus ulmifolius is a species of wild blackberry known by the English common name elmleaf blackberry or thornless blackberry and the Spanish common name zarzamora. It is native to Europe and North Africa, and has also become naturalized in parts of the United States (especially California), Australia, and southern South America.

Rubus ulmifolius is a brambly shrub sometimes as much as 5 meters (almost 17 feet) tall, sometimes with spines but not always. Leaves are palmately compound with 3 or 5 leaflets, the leaflets green on the upper surface but white on the underside because of a dense layer of woolly hairs. Flowers are usually pink, sometimes white. The fruit is a compound drupe, dark purple, almost black.

Rubus ulmifolius is found in its native range across Western Europe, from the Netherlands south to Spain and Portugal, in Britain and Ireland, as well as NW Africa. It is naturalised in North America, South America, Australasia and South Africa.[citation needed] In Britain and Ireland it is a plant of hedges and woodland edges on calcareous soils.

9-7-2018 LAGUNAS DE REY, RUIDERA - GREAT CRESTED GREBE (Podiceps cristatus)


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

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

This species prefers vegetated areas of freshwater lakes for breeding.

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

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

8-7-2018 TABLAS DE DAIMIEL, LA MANCHA - GREAT BANDED GRAYLING BUTTERFLY (Brintesia circe)


Brintesia is a monotypic butterfly genus in the family Nymphalidae and subfamily Satyrinae. Its one species is Brintesia circe, the great banded grayling.

Brintesia circe reaches on average wingspan of 65–80 millimetres (2.6–3.1 in). Its wings are mainly black or dark brown. They have a broad white band at the edge of the basal area of all wings and usually a second white streak on the lower wings. The black eyespots on the underside of the upper wings have a white contour. Brintesia circe is quite similar to Hipparchia fagi, but in the latter the second white streak on the lower wings is always missing and the eyespots have a yellow contour. These butterflies usually rest on the branches of a tree, protected by their cryptic markings, but ready to take off and fly away when disturbed.


The butterflies are on the wing from July till September, flying with preference on grassy inclines where single oak-trees grow, and settle on bare places on the ground, mole-hills and on tree-trunks, always with the head upwards and the wings tightly closed and placed one over the other, the underside being adapted to the bark of trees. They rarely visit flowers, and then usually thistles, but one more often finds them on damp places on the roads. The flight of the males is slow, searching, but tumbling and rather fast when disturbed. In South Europe the species appears to occur everywhere very commonly, and it is still very abundant also in southern Germany (Darmstadt), being but rare in the north, extending to Waldeck and the Harz Mts.; more abundant and stronger in the west, near Toulouse for instance in giant specimens. At the south coast of Europe the species occurs in countless numbers; I counted once near Genoa more than 30 specimens on one tree.


These butterflies fly in one generation from June to September feeding on nectar of flowers. Larvae feed on various herbaceous plants (mainly on Anthoxanthum, Bromus, Festuca and Sesleria species). The young larvae overwinter.

The species can be found in central and southern Europe (Spain, France, Italy, Greece, southern Germany and Poland), in Anatolia and the Caucasus up to Iran.

These butterflies prefer light woodland, grasslands bordering forest edges and generally dry and bushy environments, at an altitude of 0–1,600 metres (0–5,249 ft) above sea level.

Brintesia circe venusta (Fruhstorfer, 1909)

8-7-2018 TABLAS DE DAIMIEL, LA MANCHA - EURASIAN REED WARBLER (Acrocephalus scirpaceus)


The Common Reed Warbler, Acrocephalus scirpaceus, is a medium-sized warbler measuring approximately 13 cm in length with a wingspan ranging from 17 to 21 cm. It exhibits an unstreaked brown back with buff underparts. Both sexes are identical in appearance, which is typical for warblers. Juveniles can be distinguished by their richer buff underparts. The species is characterized by a flattened forehead and a robust, pointed bill.

When identifying the Common Reed Warbler, look for its brown, unstreaked back and buff underparts. The bird's supercilium is less pronounced than that of the larger Great Reed Warbler. In flight, observe the wing-span and listen for its distinctive song.

This species is almost exclusively found in reed beds, often with interspersed bushes, providing it with the necessary cover and nesting sites.

The Common Reed Warbler breeds across Europe into the temperate western Palaearctic and is migratory, wintering in sub-Saharan Africa. It is also a resident species in large parts of Africa.

Males typically arrive at breeding grounds a few weeks before females. The species is generally monogamous, with pairs raising up to two broods per season. It is known to be brood parasitized by the Common Cuckoo.


The song of the Common Reed Warbler is a distinctive slow, chattering "jit-jit-jit" with acrocephaline whistles and mimicry.

Nests are built by the female over water, often in reeds, and are deep cylindrical cups. Clutches usually contain three to five pale green eggs with olive or grey speckles. Both parents incubate the eggs, which hatch after 9-12 days. Fledglings leave the nest after 10-12 days but are fed by parents for an additional 10-14 days.

The Great Reed Warbler is similar in appearance but is larger and has a more pronounced supercilium.

The Common Reed Warbler is primarily insectivorous but may occasionally consume plant material such as berries.

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - CRESTED LARK (Galerida cristata)


The Crested Lark (Galerida cristata) is a small, robust passerine bird, approximately 17 cm in height with a wingspan ranging from 29 to 38 cm. It weighs between 37 and 55 grams. Both sexes are similar in appearance, with a brown plumage that is paler on the underparts and a distinctive crest on the head, which is raised prominently during displays. The tail is short with light brown outer feathers, and the underwings exhibit a reddish hue in flight.

Adult Crested Larks are characterized by their brown, streaky plumage with a paler underside. The young birds can be identified by the additional spots on their backs. The species' most notable feature is its crest, which can be seen at all times but is particularly prominent during territorial or courtship displays. In flight, the reddish underwings are a key identification marker.

The Crested Lark is found in dry, open landscapes such as fields, roadsides, and wastelands. It has adapted well to human-altered environments and can often be seen in areas with sparse vegetation, such as sandy patches near railways, docks, and airfields.

This lark has a wide range across temperate Eurasia, from Portugal to northeastern China and eastern India, and in Africa down to Niger. It is a resident bird, meaning it does not migrate seasonally. However, it is a rare vagrant to Great Britain.


The Crested Lark is known for its undulating flight pattern and its melodious, warbling song, which can be heard from high in the sky or at ground level. It is a territorial bird that sings to establish its presence, often from a height of 30 to 60 meters.

The song of the Crested Lark is a liquid series of notes, often transcribed as "whee-whee-wheeoo" or "twee-tee-too." It is a characteristic sound of open country in its range.

The Crested Lark nests on the ground in shallow depressions, using dead grasses and roots to construct its nest. It typically lays three to five brown, finely speckled eggs, which hatch after about 11 to 12 days. The young are precocial and leave the nest early, becoming fully fledged at around 15 to 16 days old. The species often raises two broods per year.

Primarily vegetarian, the Crested Lark feeds on grains and seeds such as oats, wheat, and barley. It also consumes insects, particularly beetles. Juveniles are fed by both parents and start foraging on their own shortly before they are capable of flight.

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - 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.

6-7-2018 TABLAS DE DAIMIEL, LA MANCHA - BOOTED EAGLE (Hieraaetus pennatus)


The booted eagle, Hieraaetus pennatus, is a medium-sized bird of prey, with a stature comparable to the common buzzard. It exhibits sexual dimorphism, with females being larger, weighing approximately 840–1,025 grams, while males are lighter at 510–770 grams. The species measures around 40 cm in length and boasts a wingspan ranging from 110 to 132 cm. It is characterized by two distinct plumage morphs: a pale variant with light grey feathers and a darker head and flight feathers, and a darker morph with mid-brown plumage and dark grey flight feathers.

The booted eagle favors wooded, often hilly landscapes with some open areas. It breeds in rocky, broken terrain but is adaptable during migration, utilizing a variety of habitats except dense forests.

This raptor has a wide distribution, breeding in southern Europe, North Africa, and across Asia, with a disjunct breeding population in southwestern Africa. Northern populations are migratory, wintering in Sub-Saharan Africa and South Asia, while the southern African populations are sedentary.

The booted eagle is typically observed flying at low altitudes, making it quite conspicuous. It is often seen in pairs or as solitary individuals. The species is known for its sophisticated courtship rituals involving elaborate flight displays.

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - BLACK WINGED STILT (Himantopus himantopus)


The Black-winged Stilt has a wide range, extending across Europe, Asia, and Africa. Some populations migrate to coastal regions in winter, while others in milder climates may remain resident or engage in short-range movements.

Black-winged Stilts are often seen foraging in shallow waters, gracefully picking insects and crustaceans from the surface. They are known to nest in small groups, sometimes alongside avocets, and exhibit a variety of courtship behaviors, including intricate displays and duets.

The flight call of the Black-winged Stilt is a sharp and clear kleek, typically heard during its aerial maneuvers.


Nests are simple bare spots on the ground near water. These birds are communal nesters and may breed in loose colonies. They have been known to breed as far north as Britain, with recent successful breeding events recorded in Southern and Northern England.
The Black-winged Stilt can be confused with other stilt species, such as the Black-necked Stilt (H. mexicanus) in the Americas, the White-backed Stilt (H. melanurus), and the Pied Stilt (H. leucocephalus) in Australasia and New Zealand.

Their diet consists mainly of insects and crustaceans, which they deftly pick from the water's surface or from wet sand.

The IUCN lists the Black-winged Stilt as Least Concern, indicating a stable global population. However, they are protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds, highlighting the importance of international cooperation in their conservation.

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - RED CRESTED POCHARD (FEMALE) (Netta rufina)


The Red-crested Pochard, Netta rufina, is a striking large diving duck. Its name is drawn from the Greek word for duck, 'Netta', and the Latin 'rufina', meaning 'golden-red', a nod to the male's vibrant plumage.

Males are resplendent with a rounded orange head, a red bill, and a contrasting black breast. Their sides are a crisp white, with a brown back and a black tail. Females, on the other hand, are clad in more subdued tones, primarily pale brown with a darker back and crown, and a whitish face. During eclipse, males resemble females but retain their red bills.

These ducks favor lowland marshes and lakes, thriving in the wetland habitats of southern Europe.

These ducks favor lowland marshes and lakes, thriving in the wetland habitats of southern Europe.

The Red-crested Pochard breeds from the steppe and semi-desert regions near the Black Sea to Central Asia and Mongolia. It is a somewhat migratory species, with northern populations wintering in the Indian Subcontinent and Africa.

Gregarious by nature, Red-crested Pochards form large flocks in the winter, often mingling with other diving ducks such as the Common Pochard. They are known to both dive and dabble for their food.


The male emits a distinctive wheezing 'veht', while the female can be heard making a series of hoarse 'vrah-vrah-vrah' calls.

Nests are constructed lakeside amidst vegetation, where they lay clutches of 8–12 pale green eggs.

While unique in appearance, the male Red-crested Pochard can be confused with other pochards during eclipse plumage, but the red bill is a distinguishing feature.

Their diet consists mainly of aquatic plants. These ducks are adept at upending in the water, a method they use more frequently than most diving ducks to forage for food.

The Red-crested Pochard is classified as Least Concern by the IUCN, and it is also a species protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - WHITE HEADED DUCK (FEMALE) (Oxyura leucocephala)


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

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

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


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

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


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

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

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - PIED AVOCET (Recurvirostra avosetta)


The pied avocet is a black and white bird with a very long, upturned beak. It lives and breeds in the coastal areas of Europe and Central Asia. In winter, the bird moves to warmer areas - to Africa or South Asia.

The avocet uses its bill to search for food. It puts its bill into the shallow water and sweeps it from side to side to scare up little animals and catch them.

When feeling threatened the pied avocet utters a series of sounds and slightly varies the pitch level. It sounds like the pied avocet approaches its enemy much faster than it really does. With a bit of luck, this will scare its enemy away. This sound effect is called the Doppler effect.

Just think of a fire truck siren. As long as the truck is approaching you, the siren sounds higher. When the truck is driving away from you, it sounds lower. This phenomenon is related to the sound waves. As long as the car is approaching it kind of pushes the sound waves ahead and compresses them, so that they sound higher.

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - BLACK TAILED GODWIT (Limosa limosa)


The black-tailed godwit, Limosa limosa, is a statuesque wader with a striking silhouette, characterized by its long legs and an equally long, straight bill. In its breeding attire, it dons an orange head, neck, and chest, while in the non-breeding season, it adopts a more subdued grey-brown plumage. Regardless of the season, it sports a distinctive black and white wingbar.

When observing the black-tailed godwit, look for its long, straight bill, which can range from 7.5 to 12 cm in length, and its tall, elegant stance. The bill's base is tinged with yellowish or orange-pink during the breeding season, turning pink in winter. The legs are a dark hue, varying from grey to black. In flight, the bold black and white pattern on its wings and a white rump are conspicuous markers. Compared to the bar-tailed godwit, the black-tailed has a straighter bill and longer legs, and stands taller.



The black-tailed godwit favors a range of wetland habitats for breeding, including fens, lake edges, damp meadows, moorlands, and bogs. It is also known to adapt to human-altered landscapes such as wet grasslands and pastures.
This species has a broad breeding range that spans from Iceland across Europe to central Asia. During the northern hemisphere winter, it migrates to diverse regions including the Indian subcontinent, Australia, New Zealand, western Europe, and west Africa.

The black-tailed godwit is a sociable bird, often seen migrating in flocks. It exhibits a strong fidelity to its breeding grounds, where pairs reunite each season with remarkable punctuality. If a mate is delayed, 'divorce' may ensue.


The most frequently heard call of the black-tailed godwit is a loud and insistent "weeka weeka weeka."

These godwits are predominantly monogamous, with a tendency towards bigamy in some cases. They nest in loose colonies, with males establishing temporary territories for courtship. Both parents share the duty of incubating the olive-green to dark brown eggs, and the young are precocial, leaving the nest shortly after hatching.


The bar-tailed godwit is the species most similar in appearance to the black-tailed godwit, but differences in bill shape, leg length, and plumage, particularly in flight, aid in their distinction.


The diet of the black-tailed godwit is varied, consisting mainly of invertebrates such as beetles, flies, and worms, with the addition of aquatic plants during winter and migration. They forage by probing in the mud or picking prey from the surface.

The black-tailed godwit is classified as Near Threatened, with an estimated global population of 634,000 to 805,000 birds. Conservation efforts are in place to address the decline in numbers and to manage the pressures from hunting in certain regions.

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - LITTLE EGRET (Egretta garzetta)


The Little Egret, Egretta garzetta, is a dainty heron adorned in pure white plumage. It is characterized by a slender black beak, long black legs, and, notably in the western race, yellow feet. This elegant bird is a sight to behold with its graceful neck and poised stance.

Adult Little Egrets measure between 55–65 cm in length with a wingspan of 88–106 cm, and weigh 350–550 g. Their plumage is predominantly white, though some may exhibit bluish-grey coloration. Breeding adults boast ornate nape plumes reaching about 150 mm, along with distinctive feathers on the breast and elongated scapulars. The bill and lores are black, with greenish-grey skin at the base of the lower mandible and around the eye, which houses a yellow iris. Legs are black with contrasting yellow feet, though juveniles may have greenish-black legs and duller feet. The subspecies E. g. nigripes is distinguished by yellow skin between the bill and eye, and blackish feet. 

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - COMMON POCHARD (FEMALE) (Aythya ferina)


The Common Pochard (Aythya ferina) is a medium-sized diving duck, belonging to the family Anatidae. It is a bird of robust build, with a sloping forehead and a relatively long bill. The male is distinguished by its chestnut head and neck, black breast and tail, and pale grey body with fine vermiculations. The female is more subdued in coloration, with a brownish body and a less vibrant head and neck.

Males can be identified by their striking chestnut head and neck, black breast, and pale grey body. They have a dark grey bill with a blue-grey band and yellow-orange to red irises, which intensify during the breeding season. Females and juveniles are less colorful, with brownish tones and grey legs and feet. The female's iris is brown, sometimes with a yellowish tinge, while juveniles have a yellow-olive iris that darkens with age.

The Common Pochard favors marshes and lakes with at least a meter of water depth for breeding. These habitats provide the necessary cover and food resources for the species.


This species has a widespread distribution across the Palearctic. It breeds mainly in the steppe regions of Scandinavia and Siberia and winters in the south and west of Europe. In the British Isles, it breeds in eastern England and lowland Scotland, with increasing numbers in Northern Ireland and sporadically in the Republic of Ireland.

Common Pochards are gregarious, forming large flocks in winter, often alongside other diving duck species. They are strong fliers, capable of reaching speeds of 49-54 mph in direct flight.

The male is generally silent but may emit a soft whistle during courtship. The female produces a soft growl when disturbed, and ducklings have a short contact call, which becomes higher and faster when they are distressed.

The female constructs a platform nest of plant material, lined with down, either on the ground near water or over water on a platform. Clutches typically consist of 8-10 greenish-grey eggs, with incubation beginning only after the entire clutch is laid. The species is known for high rates of conspecific brood parasitism.

Common Pochards feed on plant material, seeds, small fish, molluscs, and aquatic invertebrates, obtained by diving or dabbling. They often forage in association with Bewick's and Whooper Swans, benefiting from the swans' sediment-disturbing activities.

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - EURASIAN SKYLARK (Alauda arvensis)


The Eurasian skylark (Alauda arvensis) is a passerine bird in the lark family, Alaudidae. It is a widespread species found across Europe and the Palearctic with introduced populations in Australia, New Zealand and on the Hawaiian Islands. It is a bird of open farmland and heath, known for the song of the male, which is delivered in hovering flight from heights of 50 to 100 metres (160 to 330 ft). The sexes are alike. It is streaked greyish-brown above and on the breast and has a buff-white belly.

The female Eurasian skylark builds an open nest in a shallow depression on open ground well away from trees, bushes and hedges. She lays three to five eggs which she incubates for around 11 days. The chicks are fed by both parents but leave the nest after eight to ten days, well before they can fly. They scatter and hide in the vegetation but continue to be fed by the parents until they can fly at 18 to 20 days of age. Nests are subject to high predation rates by larger birds and small mammals. The parents can have several broods in a single season.

6-7-2018 TABLAS DE DAIMIEL, LA MANCHA - EUROPEAN BEE-EATER (Merops apiaster)


The European bee-eater, Merops apiaster, is a bird of arresting beauty and grace. Its plumage is a kaleidoscope of warm hues, with brown and yellow adorning its upper parts, while the wings boast a vibrant green. The beak, a stark black, contrasts sharply with the bird's colorful attire. This slender avian can reach a length of 27–29 cm, including the elongated central tail feathers that add to its elegance. Both sexes are similar in appearance, though the female may sport greener shoulder feathers compared to the male's gold.

When identifying the European bee-eater, look for its distinctive coloration and sleek profile. The non-breeding plumage is more subdued, with a blue-green back and the absence of elongated central tail feathers. Juveniles resemble non-breeding adults but exhibit less variation in feather colors. During the moulting period, adults transition to breeding plumage, which is completed before their winter migration to Africa.

These birds favor open country in warmer climates, often found in proximity to sandy banks and river shores where they can nest and forage with ease.

The European bee-eater breeds across southern and central Europe, parts of northern and southern Africa, and western Asia. While the southern African population remains resident year-round, others migrate to tropical Africa for the winter. Occasionally, they are seen north of their typical range, with sporadic breeding in northern Europe.


Gregarious by nature, European bee-eaters nest colonially in sandy banks, with communal tendencies extending to feeding and roosting. Courtship involves the male presenting the female with large prey items, a gesture of both affection and sustenance.

The call of the European bee-eater is a melodious and liquid "prreee" or "prruup," a sound as mellow as the bird's demeanor.


Breeding season sees these birds tunneling into sandy banks to lay their spherical white eggs, with both parents sharing the duties of incubation and care. The eggs hatch after about three weeks, and the young are raised with communal diligence.

While the European bee-eater is distinctive, it may be confused with other bee-eater species. However, its unique coloration and tail feathers generally set it apart.

True to their name, European bee-eaters feast primarily on bees, wasps, and hornets. They exhibit remarkable skill in catching these insects mid-flight and have a unique method of removing the sting before consumption. Their diet is predominantly composed of Hymenoptera, particularly the European honey bee.

The IUCN lists the European bee-eater as Least Concern, indicating a stable population without immediate threats to its survival. However, their interactions with bee populations and apiaries are of interest to conservationists and apiculturists alike.

4-7-2018 ALBUFERA, 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.

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.

4-7-2018 RACO DE OLLA, VALENCIA - BLACK WINGED STILT (Himantopus himantopus)


Black-winged stilts (Himantopus himantopus) are very long-legged wading birds. They are found in both warm and hot climates, feed on small aquatic creatures, and nest on the ground surface in small colonies.

Adult Black-winged stilts have long, pink legs, and a long, rather thin black bill. They are generally black above and white below, with a white head and neck. Males have a black back, often with a greenish gloss or sheen. Females' backs have a brownish hue, contrasting with the black remiges. In populations where the top of the head is normally white (at least in winter), females tend to have less black on the head and neck the entire year round, while males often have much more black, particularly in summer. This difference is not clear-cut, however, and males usually grow all-white head feathers in winter. Immature birds are grey, instead of black, and have a markedly sandy hue on their wings, with light feather fringes appearing as a whitish line in flight.


Black-winged stilts are found across Europe, Asia, Africa, Australia, and North, Central and South Americas. Some populations are migratory and move to the ocean coasts in winter; those in warmer regions are generally resident or short-range vagrants. Black-winged stilts breed in freshwater and brackish marshes, shallow lakes, ponds, and flooded fields. They can also be found in mountainous areas near lakes, river deltas, estuaries, coastal lagoons and marshes, salt meadows, and mudflats.

Black-winged stilts are very gregarious birds. They often gather in groups of around 20 individuals and may migrate or roost in large flocks of several thousand birds. Black-winged tilts are mainly diurnal; however, they are also adapted to nocturnal vision and may also forage even on moonless nights. Black-winged stilts feed in shallow water, wading slowly picking up their food from the water surface or sand.

Black-winged stilts are carnivores (insectivores, molluscivores, vermivores). They eat mainly insects and crustaceans but may also take tadpoles, mollusks, worms, and spiders.
