8-7-2018 TABLAS DE DAIMIEL, LA MANCHA - FERRUGINOUS DUCK (Aythya nyroca)

The Ferruginous Duck, known scientifically as Aythya nyroca, is a medium-sized diving duck hailing from the vast expanses of Eurosiberia. The males are adorned with a rich, dark chestnut plumage on their heads, breasts, and flanks, which is set off by the stark white of their undertail coverts. When in flight, their white bellies and underwing patches become conspicuous. Females present a more subdued palette, being duller and browner. A notable feature of the male is its yellow eye, while the female's eye is dark.

To identify the Ferruginous Duck, look for the male's distinctive yellow eye and rich chestnut coloring. In contrast, the female will have a dark eye and a browner hue. When the bird takes to the air, observe the white belly and underwing patch that become visible, aiding in its identification.

The Ferruginous Duck shows a preference for shallow freshwater bodies teeming with rich submerged and floating vegetation. The margins of these waters are often densely populated with emergent vegetation. While it may occasionally inhabit saline or brackish pools or wetlands, during migration and wintering, it is also known to frequent coastal waters, inland seas, and large open lagoons.

This duck's breeding range stretches from Iberia and the Maghreb eastward to western Mongolia, and southward to Arabia. However, in the western part of its range, it has become scarce and localized, with some countries reporting local extirpation. In winter, the species disperses throughout the Mediterranean Basin and the Black Sea, with some migrating into sub-Saharan Africa via the Nile Valley. Eastern populations winter in South and Southeast Asia.

Ferruginous Ducks are sociable, yet they are less so than other species within the Aythya genus. In regions where they are common, they may form large flocks in the winter, often mingling with other diving ducks like tufted ducks and common pochards. They begin pairing from January, and during courtship, males may exhibit a tail-curling behavior that dips the tail into the water, highlighting the white undertail coverts. They may form colonies in protected areas, such as islands, sometimes alongside gulls, or nest singly in more concealed locations when less common.

The nesting period commences at the end of April or the start of May. Nests are constructed on the ground near water or occasionally as floating structures amidst emergent vegetation. The incubation of eggs spans 25–27 days, and the young take 55–60 days to fledge.

These ducks primarily feed by diving or dabbling. Their diet consists mainly of aquatic plants, supplemented with molluscs, aquatic insects, and small fish. They are known to feed nocturnally and exhibit both upending (dabbling) and diving behaviors in their quest for sustenance.

The Ferruginous Duck faces threats from habitat degradation and destruction due to a variety of human activities, including impoundment, drainage, pollution, and mismanagement. The introduction of non-native species, such as grass carp, has also contributed to habitat degradation by reducing plant and animal biomass. Climate change-induced droughts pose additional threats, particularly in the drier parts of their range. Disturbance from fishing boats and anglers can lead to breeding site abandonment or disrupted breeding timing, especially in populated areas like Western Europe. Despite protection in most European countries, illegal and accidental hunting continues to threaten this species. The Ferruginous Duck is covered by the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA). Local conservation efforts include the protection of breeding habitats in Armenia as part of the network of Emerald Sites under the Bern Convention.

8-7-2018 TABLAS DE DAIMIEL, LA MANCHA - COMMON MALLOW (Malva sylvestris)

Malva sylvestris is a species of the mallow genus Malva, of which it the type species. Known as common mallow to English-speaking Europeans, it acquired the common names of cheeses, high mallow and tall mallow (mauve des bois by the French) as it migrated from its native home in Western Europe, North Africa and Asia through the English-speaking world.

M. sylvestris is a vigorous plant with showy flowers of bright mauve-purple, with dark veins, standing 0.91–1.22 metres (3–4 ft) high and growing freely in meadows, hedgerows and in fallow fields.

It is one of several species of different genera sometimes referred to as Creeping Charlie, a term more commonly applied to Glechoma hederacea (ground ivy).

Common mallow is a herbaceous perennial with an erect or decumbent branched stem up to 1.5 metres (5 ft) tall. The minutely ridged stems are covered with fine soft hairs, sometimes with a slightly bulbous base. The leaves are alternate, with a petiole up to 20 centimetres (8 in) long, simple but palmate, up to 7 cm long by 10 cm wide, with stellate hairs (i.e. several strands radiating from a common center) and prominent veins on the underside.

The flowers are reddish-purple with dark stripes and occur in axillary clusters of 2 to 4 along the main stem with the flowers at the base opening first. There are 5 petals, each being up to 2 cm (3⁄4 in) long, and 5 sepals, 3–6 mm long, which are fused in the lower half, and have broadly triangular lobes. There is also an epicalyx (or false calyx) with oblong segments, two-thirds as long as calyx lobes (2–3 mm long x 1.5 mm wide).

8-7-2018 TABLAS DE DAIMIEL, LA MANCHA - WHITE STORK (Ciconia ciconia)

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

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

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

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

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

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

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

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

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

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

8-7-2018 TABLAS DE DAIMIEL, LA MANCHA - EUROPEAN MOORHEN (JUVENILE) (Gallinula chloropus)

The common moorhen, known scientifically as Gallinula chloropus, is a bird of the rail family, Rallidae. It is a bird of striking appearance, with a mix of black and brown plumage, a white under-tail, and white streaks along its flanks. Its legs are a vibrant yellow, and it sports a distinctive red frontal shield. The bill is a matching red with a yellow tip. Juveniles are a duller brown and do not have the red shield.

Adult moorhens can be identified by their red frontal shield, which has a rounded top and fairly parallel sides. The tailward margin of the red unfeathered area is smoothly curved. Their yellow legs and the combination of their black and brown plumage with white markings make them quite distinctive. The young are browner and lack the red shield, making them less conspicuous.

The common moorhen is found in a variety of wetland habitats, including marshes, ponds, canals, and lakes that are rich in vegetation. It is also known to inhabit city parks with suitable water bodies.

This species has a broad distribution across many parts of the Old World. It is not found in polar regions or many tropical rainforests but is otherwise widespread, often being the most common rail species in its range.

Moorhens are known for their secretive nature but can become quite tame in certain areas. They exhibit territorial behavior during the breeding season and are known to aggressively defend their territory against intruders.

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 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.

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.

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).

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.
