23-3-2018 BOULDER BAY, SOUTH AFRICA - MILE A MINUTE VINE (Ipomoea cairica)

Ipomoea cairica is a vining, herbaceous, perennial plant with palmate leaves and large, showy white to lavender flowers. A species of morning glory, it has many common names, including mile-a-minute vine, Messina creeper, Cairo morning glory, coast morning glory and railroad creeper. The species name cairica translates to "from Cairo", the city where this species was first collected.

A hairless, slim climber with bulbous roots and lignescented base, its leaves are stalked with 2 to 6 cm long petioles. The leaf blade is ovate to circular in outline, 3 to 10 cm long and 6 to 9 cm wide. It is divided into five to seven segments, these are lanceolate, ovate or elliptic, entire and pointed at the tip and base. Often pseudo side-leaves are formed.

The lavender-coloured inflorescences are one to a cyme. The flower stalks are 12 to 20 mm long, the sepals are 6 to 8 mm long, ovate and sting-pointed. The crown is funnel-shaped, 4 to 6 cm long and violet colored. The stamens and the stylus do not protrude beyond the crown. The ovary is hairless. The fruits are spherical capsules approximately 1 cm in diameter containing one or two hairy seeds. Each fruit matures at about 1 cm across and contains hairy seeds. The vine blooms occasionally throughout the months, but more profusely from spring to summer.

23-3-2018 BOULDER BAY, SOUTH AFRICA - KAROO PRINIA (karoo prinia)

The Karoo prinia, or spotted prinia (Prinia maculosa), presents itself as a small, active passerine bird, measuring between 13 to 15 centimeters in length. It is adorned with short, rounded wings, a longish tail that it often holds cocked, and robust legs. Its bill is short and straight, colored a deep black. The bird's head features a whitish eyebrow, while the upperparts are a plain brown. The throat and lower face are whitish with dark streaking, and the underparts are a pale yellowish white or yellow, marked with distinct black streaking. A notable dark spot near the end of the long tail adds to its distinctive appearance. The feet and legs are a pinkish-brown, and the eye is a deep, dark brown. Both sexes of the Karoo prinia are identical in plumage, though juveniles can be distinguished by their much yellower underparts and lighter streaking.

When identifying the Karoo prinia, look for the bird's whitish eyebrow and the streaked underparts. The tail is typically held at an angle and has a dark spot near the end. Juveniles are yellower below and less heavily streaked than adults.

This species is found in karoo scrub, fynbos, and bracken-covered slopes, favoring semi-desert and mountainous environments.

The Karoo prinia is a resident breeder in South Africa, Lesotho, and the southernmost parts of Namibia.

The Karoo prinia is often observed in pairs or small groups. It is a bird that prefers the lower strata of scrub but may occasionally be seen perching atop a bush. It is known for its active foraging behavior, searching for small insects with a tail that is characteristically cocked and swung from side to side.

The vocal repertoire of the Karoo prinia includes a sharp "chleet-chleet-chleet-chleet-chleet-chleet" and a fast, buzzy "tit-tit-tit-tit-tit."

Breeding behavior includes constructing a thin-walled oval nest with a side entrance, woven from green grass and well concealed within a leafy shrub or bush. The breeding season varies by region, occurring from August to September in areas with winter rainfall and extending to December in other locales.

The diet consists primarily of small insects, which the Karoo prinia actively seeks out in its preferred habitats.

The Karoo prinia is classified as Least Concern by the IUCN Red List. It has a large range, estimated at 670,000 square kilometers, and the population size is believed to be large, with no immediate threats that would warrant concern over population decline.

23-3-2018 BOULDERS BAY, SOUTH AFRICA - CAPE WAGTAIL (Motacilla capensis ssp capensis)

The Cape wagtail, or Wells's wagtail, is a modestly adorned bird with a relatively short tail. Its upperparts are an unassuming olive grey, while the face is similarly hued, accented by a tan supercilium and dark lores. The underparts are a soft creamy white, occasionally showing a subtle pinkish tinge on the lower breast and belly. A dusky breast band is present, and the flanks share the olive-grey of the breast. The wings are a brownish black with pale feather edging, and the tail is predominantly blackish, save for the white outer feathers. Juveniles resemble adults but are a touch browner above and have a more yellowish hue below.

Look for the iconic black triangle on the chest, a key feature for identification. There is no sexual dimorphism in plumage, so males and females appear alike.

The Cape wagtail is a versatile species, inhabiting areas near water such as riverbanks, as well as rocky coastlines, farms, villages, cultivated lands, parks, gardens, and urban centres. In East Africa, it is typically found at altitudes above 2,000 meters.

This bird is widespread in eastern and southern Africa, ranging from Uganda and Kenya, through Zambia and Angola, and down to the Western Cape and the Cape of Good Hope.

The species is mostly resident and territorial, but some may migrate altitudinally or form flocks outside the breeding season.

Cape wagtails are monogamous and may remain with their breeding partner across multiple seasons. They are solitary nesters, constructing nests in a variety of natural and artificial recesses. Breeding can occur year-round, with a peak from mid-winter to early summer. Clutches typically consist of one to five eggs, incubated by both parents for about two weeks. Chicks are fed by both parents and fledge in about two to three weeks, with full independence reached approximately one to two months post-fledging.

The Cape wagtail's diet consists mainly of invertebrates, which it hunts on the ground or in shallow water. It is known to feed on a variety of prey, including insects, fiddler crabs, sandhoppers, snails, ticks, tadpoles, small fish, and even small chameleons. It is also known to consume carrion and occasionally human food.

23-3-2018 BOULDERS BAY, SOUTH AFRICA - SOUTHERN ROCK AGAMA (Agama atra)

The southern rock agama or southern African rock agama (Agama atra) is a species of lizard from the family Agamidae that occurs in Southern Africa in Zambia, South Africa, Eswatini, Mozambique, Zimbabwe and Botswana. It lives in small colonies on rocky outcrops, and the males are very conspicuous for their bright blue heads.

The natural range of this species is over the entire South Africa and Botswana, excluding only sandy areas of the Northern Cape and portions of the Limpopo, Mpumalanga, and KwaZulu-Natal provinces.

This rather sociable agama is normally found in small groups or colonies. It grows up to about 25 cm and has a thin dorsal crest that runs the length of its body. It typically has a short, plump body and a thin tail, with a triangular head. During the breeding season, the heads of the males become bright blue. The males also take to sitting on top of prominent rocks and are therefore a common sight in mountainous areas of South Africa. The females and young are a more uniform greyish-brown and are much more shy.

These active, diurnal lizards normally hunt small insects such as ants and termites. They sometimes adjust to living near urban areas and can even live in rocky gardens. However, the increasingly dense populations of domestic cats being kept as pets in suburban areas have unfortunately led to a decline in population, as these introduced predators tend to kill all the agamas in the immediate area. Agama atra's natural predators in the wild include the fiscal shrike and various snakes. Agama atra is also easy prey for eagles and larger reptiles. Under attack the Agamas go into hiding and will only return once the danger is over. Some Agamas are kept as household pets and generally have a good relationship with their pet owners.

A. atra has some ability to change colour, although not to the same extent as chameleons, of which the Agamidae are a sister group. When a male agama in breeding colouration is approached by a potential predator, it will lie flat against a rock and lose the intense breeding colours in favour of more cryptic colouration. A dominant male usually occupies a high point in the area and performs a pushup display and head nodding to warn off intruders.

12-6-2018 MONTE CORONA, VALENCIA - CATALONIA WALL LIZARD (Podarcis liolepis)

Podarcis liolepis, the Columbretes wall lizard or Catalan wall lizard, is very similar to the other lizards in the genus Podarcis. This species was formerly described as a subspecies of the Iberian wall lizard, but has now been elevated to species status. These are slender lizards with long tails, narrow tapered heads and long thin toes, and stout legs. Colours are variable, although generally grey-brown. Often very subtle spots and stripes along the back and flanks can be seen and these can be more distinguished in the female. The underside is a much lighter cream or beige with sometimes a reddish tint. Adults grow 15–20 cm in length from the nose to tip of the tail. Body length can be a little as one third of the total body length, the tail making up the other two thirds.

This species is one of 28 currently described species of the genus Podarcis. Podarcis liolepis is one of eight species in a monophyletic clade of Iberian and North African wall lizards (Kaliontzopoulou et al., 2011; Yang et al., 2021). The distribution of these species is complex and with several hybrid zones (Caeiro-Dias et al., 2018; Caeiro-Dias et al., 2021; Gaczorek et al., 2023; Pinho et al., 2008). Podarcis liolepis is also found on several islands in the Columbretes archipelago east of the Iberian Peninsula (Böhme, 1986).

The Catalan wall lizard inhabits a range of different habitats, from sea level to >1700 m altitude. The species can be common in urban environments. Lizards can be active all year round, except at high altitude, but breeding is restricted to spring and early summer. The species is oviparous and Meiri et al. (2020) report an average clutch size of 2.80.

The Catalan wall lizard is a relatively small-bodied wall lizard. In continental populations, males range 44.9–65.7 mm in snout-to-vent length (SVL) whereas females range 43.3–61.3 mm in SVL (Carazo et al., 2011; Carretero & Salvador, 2016). Lizards from the Columbretes archipelago are larger with an average SVL of 65.3–68 in males and 61.7-61.9 in females (Castilla & Bauwens, 1991a; Castilla & Bauwens, 1991b). The dorsum of this species is mostly showing a reticulated pattern with brown or green hues on a darker background. As in most species of Podarcis, the sexes differ in appearance with females being generally smaller and showing a pattern that is more dominated by longitudinal stripes. This species is one of several Podarcis that exhibit ventral color polymorphism with yellow, orange/red and white morphs 

12-6-2018 MONTE CORONA, VALENCIA - EPAULET SKIMMER DRAGONFLY (Orthetrum chrysostigma)

Orthetrum chrysostigma, the epaulet skimmer, is a species of dragonfly in the family Libellulidae. It is found in Algeria, Angola, Benin, Botswana, Burkina Faso, Cameroon, Central African Republic, Chad, the Democratic Republic of the Congo, Ivory Coast, Egypt, Equatorial Guinea, Ethiopia, Gambia, Ghana, Guinea, Kenya, Liberia, Libya, Malawi, Mali, Mauritania, Morocco, Mozambique, Namibia, Niger, Nigeria, Senegal, Sierra Leone, Somalia, South Africa, Sudan, Tanzania, Togo, Uganda, Zambia, Zimbabwe, and possibly Burundi as well as Canary Islands, Israel, and Portugal. It was recorded in the Maltese Islands in 2010. One was also spotted in Tel Aviv, Israel in August 2022.

Its natural habitats are subtropical or tropical moist lowland forests, dry savanna, moist savanna, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, rivers, intermittent rivers, shrub-dominated wetlands, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, and freshwater springs. The adults prey on various flying insects. The bodies of adult males are blue, and those of young and females are yellow and brown. 

12-6-2018 MARCHUQUERA, VALENCIA - EURASIAN TREE SPARROW (MALE) (Passer montanus)

The Eurasian tree sparrow (Passer montanus) is a charming passerine bird, easily recognized by its rich chestnut crown and nape, and a distinctive black patch on each pure white cheek. Both sexes are similarly adorned, and the juveniles mirror the adults, albeit with slightly duller hues. This species is somewhat smaller than the closely related house sparrow, and its size is approximately 12.5–14 cm in length, with a wingspan of about 21 cm.

To identify the Eurasian tree sparrow, look for the kidney-shaped black ear patch on each white cheek, the black chin and throat, and the light brown upperparts streaked with black. The wings bear two narrow white bars, and the legs are pale brown. The bill is lead-blue in summer, darkening almost to black in winter. Unlike the house sparrow, there is no sexual dimorphism in plumage, making both males and females equally easy to identify.

In Europe, the Eurasian tree sparrow is typically found in lightly wooded open countryside, while in eastern Asia, it is more common in urban settings. It prefers nesting in natural cavities, holes in buildings, or even the abandoned nests of other large birds. This species is not typically found in mountainous regions, despite its scientific name suggesting otherwise.

The Eurasian tree sparrow has a broad distribution across temperate Eurasia and Southeast Asia, and it has been introduced to other regions such as the United States. Its range extends from Europe across Asia to the Lena River and south to the northern regions of Turkey, the Caucasus, Kazakhstan, Mongolia, and North Korea.

The Eurasian tree sparrow is a sociable bird, often seen in flocks. It is sedentary in most of its range, but northern populations may migrate southward in winter. This species is known for its untidy nests and can breed in a variety of locations, from tree holes to urban structures.

The Eurasian tree sparrow does not have a true song but communicates with a series of excited "tschip" calls during courtship and other monosyllabic chirps for social interactions. Its flight call is a harsh "teck."

Breeding maturity is reached within a year, and the typical clutch consists of five or six eggs. Both parents incubate the eggs for about 12-13 days, and the chicks fledge after 15-18 days. The species may raise two or three broods each year.

Primarily a seed and grain eater, the Eurasian tree sparrow forages on the ground in flocks. During the breeding season, it also consumes invertebrates to feed its young. It is known to visit feeding stations, particularly for peanuts.

12-6-2018 MONTE CORONA, VALENCIA - JUMPING SPIDER (Menemerus semilimbatus)

Menemerus semilimbatus is a spider in the family Salticidae.

Menemerus semilimbatus are about 6.5–8.4 millimetres (0.26–0.33 in) long, the male being slightly smaller than the female. These fairly big jumping spiders are dorso-ventrally flattened and are covered with short dense, grayish-white hairs, with hairy whitish palps and a white band on the side margins of the carapace, showing also a small white, triangular marking in the middle. The eyes are large and forward-facing. The legs are light brown with darker rings and patches, while the abdomen is dorsally yellowish or grayish, with a characteristic pattern of several bright V-shaped markings. The females show a notch at the posterior edge of the epigyne and two oval depressions in the anterior half.

Menemerus semilimbatus is a Mediterranean species widely distributed in Europe, southern Asia and in Africa. In the Americas, it has been reported in Argentina, Chile, Ecuador and USA.

 These spiders are synanthropic living in gardens and inside and on the outside of houses. It is usually found on the walls of buildings where it stalks its prey.

12-6-2018 MONTE CORONA, VALENCIA - COMB CLAWED DARKLING BEETLE (Heliotaurus ruficollis)

Heliotaurus ruficollis is a species of comb-clawed beetle in the family Tenebrionidae, found in southern Europe and northern Africa. The beetles are generally black with a dark red thorax.

20-3-2018 RETIRO PARQUE, MADRID - MEXICAN PLUM (Prunus mexicana)

Prunus mexicana, commonly known as the Mexican plum, Inch plum, and Bigtree plum, is a North American species of plum tree that can be found in the central United States and Northern Mexico.

Prunus mexicana has a single trunk, an open crown, and reaches a height of 15–38 feet (4.6–11.6 m).[3] It has dark green, simple ovate leaves 2–4.5 inches (5.1–11.4 cm) long and 1.25–2 inches (3.2–5.1 cm) wide. In the early spring it is covered with five-petaled fragrant white or pale pink flowers 0.75–1 inch (19–25 mm) wide. Its dark gray bark is banded with horizontal lenticels. The dark red or purple fruit ripens late in the fall.

Prunus mexicana is very similar to Prunus americana, and they intergrade along a broad contact zone centered around Arkansas and Missouri. These intermediate individuals may be impossible to assign to a specific species.

20-3-2018 RETIRO PARQUE, MADRID - YELLOW BELLIED SLIDER TERRAPIN (Trachemys scripta.scripta)

The yellow-bellied slider (Trachemys scripta scripta ) is a land and water turtle belonging to the family Emydidae. This subspecies of pond slider is native to the southeastern United States, specifically from Florida to southeastern Virginia, and is the most common turtle species in its range. It is found in a wide variety of habitats, including slow-moving rivers, floodplain swamps, marshes, seasonal wetlands, and permanent ponds. Yellow-bellied sliders are popular as pets.

Adult male yellow-bellied sliders typically reach 5–9 inches (13–23 cm) in length; females range from 8–13 inches (20–33 cm). The carapace (upper shell) is typically brown and black, often with yellow stripes. The skin is olive green with prominent patches of yellow down the neck and legs. As the name implies, the plastron (bottom shell) is mostly yellow with black spots along the edges. Adults tend to grow darker as they age. Yellow-bellied sliders are often confused with eastern river cooters, who also have yellow stripes on the neck and yellow undersides, but the latter lack the green spots characteristic of this species. The yellow belly often has an "s"-shaped yellow stripe on its face. They also have markings shaped like question marks on their bellies. Females of the species reach a larger body size than the males do in the same populations.

20-3-2018 RETIRO PARQUE. MADRID - BLACK SWAN (Cygnus atratus)

The black swan (Cygnus atratus) is a striking large waterbird, native to the southeastern and southwestern regions of Australia. It is characterized by its predominantly black plumage and a distinctive red bill, with a pale bar and tip. The legs and feet are a greyish-black hue. Males, known as cobs, are marginally larger than females, or pens, and possess a longer, straighter bill. Juveniles, referred to as cygnets, display a greyish-brown coloration with pale-edged feathers.

Adult black swans range from 110 to 142 centimeters in length and weigh between 3.7 and 9 kilograms. Their wingspan stretches from 1.6 to 2 meters. Notably, they have the longest neck relative to body size among swans, which is typically curved into an elegant "S" shape.

Black swans inhabit a variety of wetland environments, including fresh, brackish, and saltwater lakes, as well as swamps and rivers with abundant underwater and emergent vegetation. They are also found in permanent wetlands and ornamental lakes, and may occasionally venture into flooded pastures, tidal mudflats, or the open sea near islands or the coast.

Within Australia, black swans are common in the wetlands of the southwest and east, and their range extends to adjacent coastal islands. They are nomadic birds, with migration patterns influenced by climatic conditions, such as rainfall or drought.

Black swans are highly sociable and can be observed either alone or in groups, sometimes numbering in the hundreds or thousands. They are known for their strong, undulating flight, often forming a line or a "V" formation. On the water, they may carry their feathers or wings raised in an aggressive display.

The black swan is known for its musical and far-reaching bugle-like sound, which can be heard both on the water and in flight. It also emits a range of softer crooning notes and can whistle, particularly when disturbed during breeding and nesting.

Black swans are monogamous breeders, with both partners sharing incubation and cygnet-rearing duties. They typically nest in the wetter winter months, constructing large mounds of reeds, grasses, and weeds. Clutches usually contain four to eight greenish-white eggs, incubated for about 35-40 days.

The diet of the black swan is predominantly herbivorous, consisting mainly of aquatic and marshland plants. They feed by dipping their heads under shallow water or up-ending in deeper waters, and are also capable of filter feeding at the water's surface.

20-3-2018 RETIRO PARQUE, MADRID - EURASIAN BLACKBIRD (MALE) (Turdus merula)

The Common blackbird (Turdus merula) is a species of true thrush. It is also called the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply the blackbird where this does not lead to confusion with a similar-looking local species. This common and conspicuous species has given rise to a number of literary and cultural references, frequently related to its song.

The adult male has glossy black plumage, blackish-brown legs, a yellow eye ring, and an orange-yellow bill. The bill darkens somewhat in winter. The adult female is sooty-brown with a dull yellowish-brownish bill, a brownish-white throat, and some weak mottling on the breast. The juvenile is similar to the female but has pale spots on the upperparts, and the very young juvenile also has a speckled breast. Young birds vary in the shade of brown, with darker birds presumably males. The first-year male resembles the adult male but has a dark bill and weaker eye ring, and its folded wing is brown, rather than black like the body plumage.

Common blackbirds breed in Europe, North Africa, India, and southern China. Populations in the north and east migrate to winter in Egypt and the west and southeast of Asia. Depending on latitude, Common blackbirds may be resident, partially migratory, or fully migratory. These birds live in very varied habitats, including mountainous regions and big city centers, where they inhabit open forests and forest edges, woodlands, cultivated areas, gardens, and parks if the cover is dense enough for hiding.

Common blackbirds are diurnal and eat mainly on the ground, turning the leaf litter to find the invertebrates hidden below. The bird runs for a short distance and stops suddenly to turn its head sideways to detect its prey and hops while it digs the ground with its bill to attract worms. It will feed in trees and bushes on the fruits and berries that it prefers. These birds will often take sunbaths, while flattened on grass or warm ground, with their beak open and their head inclined, and wings and tails spread. Common blackbirds are territorial, strongly defending their territory, mostly in urban areas where each pair does not have much space. Females may also fight, in defense of a good nest site. While winter food is available, Common blackbirds will stay within their territory for the year, although they will occupy different areas. Migrating birds are more gregarious, flying in small flocks and eating in loose groups at the wintering grounds.

20-3-2018 RETIRO PARQUE, MADRID - SPOTLESS STARLING (Sturnus unicolor)

The Spotless Starling, known scientifically as Sturnus unicolor, is a member of the starling family, Sturnidae. It bears a striking resemblance to its cousin, the Common Starling, but is distinguished by its slightly larger size, measuring 21-23 cm in length and weighing between 70-100 grams. Its plumage is a glossy, oily black, which may exhibit purple or green iridescence under bright light. Notably, during the spring and summer, its feathers are completely devoid of spots, while in winter, it sports only minuscule pale spots.

To identify the Spotless Starling, look for its longer throat feathers, which are double the length of those on the Common Starling, creating a pronounced "beard" especially visible when the bird vocalizes. Its legs are a vivid pink, and the bill color changes with the seasons: yellow with a bluish or pinkish base in summer, and a duller, often blackish hue in winter. Juveniles present a dull brown plumage, darker than their common counterparts, with a black bill and brown legs.

The Spotless Starling is quite adaptable, inhabiting a variety of open environments from farmlands and olive groves to urban areas. It thrives particularly well in open grazed holm oak woods and in cities like Gibraltar, where it is a common sight.

This bird has a more restricted range compared to the Common Starling, being native to the Iberian Peninsula, Northwest Africa, southernmost France, and the islands of Sicily, Corsica, and Sardinia. It is largely sedentary, with its population having expanded northward in recent decades.

The Spotless Starling is a sociable creature, often seen in sizeable flocks that can number up to 100,000 in the winter months. These flocks may include Common Starlings as well. It exhibits a strong, direct flight and, like its relative, walks rather than hops.

A vocal bird, the Spotless Starling is an accomplished mimic. Its calls are reminiscent of the Common Starling but are notably louder.

As a cavity-nesting species, the Spotless Starling makes its home in tree holes, buildings, and cliff crevices. It typically lays a clutch of three to five eggs.

An omnivorous bird, the Spotless Starling's diet includes a wide array of invertebrates, berries, and human-provided food scraps.

20-3-2018 RETIRO PARQUE, MADRID - EURASIAN MAGPIE (Pica pica)

The Eurasian magpie, or common magpie (Pica pica), is a striking bird that graces the northern reaches of the Eurasian continent. It is a member of the crow family, known as corvids, and is part of the "monochrome" magpie group within the Holarctic radiation. The bird is easily recognized by its black and white plumage and long, iridescent tail.

Adult Eurasian magpies measure 44–46 cm in length, with over half of this being the tail. They have a wingspan of 52–62 cm. The head, neck, and breast are glossy black with a metallic sheen of green and violet, while the belly and scapulars are pure white. The wings are black with green or purple gloss, and the primaries have white inner webs. The tail is black with green and reddish-purple gloss. Both sexes have similar plumage, though females are slightly smaller.

The Eurasian magpie favors open countryside with scattered trees, avoiding dense forests and treeless areas. It adapts well to suburban environments, including parks and gardens, and can be found in city centers.

This magpie's range spans temperate Eurasia from the western edges of Portugal and Spain to the eastern limits of the Kamchatka Peninsula.

The Eurasian magpie is known for its intelligence, comparable to that of great apes. It is monogamous, with pairs often remaining together across seasons. They are sedentary, though northern populations may move south in severe weather.

The magpie's call is a distinctive "chac-chac" or a repetitive "chac-chac-chac-chac." Young birds emit a similar call and a high-pitched "Uik Uik," which can resemble a small dog's bark.

Magpies typically breed after their first year. They build large, domed nests in tall trees, laying clutches of five to six pale blue-green eggs, which are incubated for 21–22 days. The chicks are altricial and fledge at around 27 days, with parental care continuing for several weeks.

Omnivorous, the Eurasian magpie's diet includes young birds, eggs, small mammals, insects, carrion, acorns, grain, and other plant matter.

With an extensive range and stable population trends in Europe, the Eurasian magpie is classified by the IUCN as Least Concern. Estimates suggest a total population of 46 to 228 million individuals globally.

20-3-2018 RETIRO PARQUE, MADRID - HOUSE SPARROW (MALE) (Passer domesticus)

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

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

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

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

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

20-3-2018 RETIRO PARQUE, MADRID - EURASIAN BLACKBIRD (MALE) (Turdus merula)

The Common Blackbird, Turdus merula, is a true thrush and a familiar sight in gardens and woodlands. The male is distinguished by its all-black plumage, bright yellow eye-ring, and orange-yellow bill, which darkens slightly during winter. Females and juveniles are more demure in their attire, sporting mainly dark brown feathers.

Adult males are entirely black with the exception of the yellow eye-ring and bill. Females are sooty-brown with a duller bill, and juveniles resemble females but have pale spots on their upperparts. The very young may also exhibit a speckled breast.

The Common Blackbird thrives in a variety of habitats including woodlands with dense undergrowth, gardens, parks, and hedgerows. It shows a preference for deciduous trees and areas with thick vegetation.

This species is widespread across Europe, western Asia, and North Africa. It has also been introduced to Australia and New Zealand. Its range varies from resident populations in the milder regions to partially or fully migratory populations in areas with more severe winters.

The Common Blackbird is territorial, especially during breeding season, with males displaying distinctive threat behaviors to ward off rivals. Outside of breeding season, they can be more sociable, often forming small flocks. The species is known for its adaptability to urban environments, where it may overwinter more readily than in rural settings.

The male's song is a melodious and fluted warble, often heard from elevated perches during the breeding season. The Common Blackbird also has a repertoire of calls including a sharp "seee" when agitated and a "pook-pook-pook" to signal ground predators.

Monogamous by nature, the Common Blackbird builds a neat, cup-shaped nest, often in dense shrubbery. The female lays three to five bluish-green eggs adorned with reddish-brown blotches. Both parents are involved in feeding the altricial chicks until they fledge.

The Common Blackbird can be confused with the Ring Ouzel or the Common Starling in Europe. In Asia, it has several similar-looking relatives, such as the Indian, Tibetan, and Chinese Blackbirds, which were once considered subspecies.

An omnivore, the Common Blackbird forages primarily on the ground for insects, earthworms, seeds, and berries. It is adept at pulling earthworms from the soil and foraging through leaf litter for other invertebrates.

The IUCN lists the Common Blackbird as Least Concern. It has a vast range and a large, stable population, though there have been localized declines due to changes in agricultural practices and urbanization.

21-3-2018 ATOCHA STATION, MADRID - YELLOW BELLIED SLIDER TERRAPIN (Trachemys scripta.scripta)

The yellow-bellied slider (Trachemys scripta scripta ) is a land and water turtle belonging to the family Emydidae. This subspecies of pond slider is native to the southeastern United States, specifically from Florida to southeastern Virginia, and is the most common turtle species in its range. It is found in a wide variety of habitats, including slow-moving rivers, floodplain swamps, marshes, seasonal wetlands, and permanent ponds. Yellow-bellied sliders are popular as pets.

Adult male yellow-bellied sliders typically reach 5–9 inches (13–23 cm) in length; females range from 8–13 inches (20–33 cm). The carapace (upper shell) is typically brown and black, often with yellow stripes. The skin is olive green with prominent patches of yellow down the neck and legs. As the name implies, the plastron (bottom shell) is mostly yellow with black spots along the edges. Adults tend to grow darker as they age. Yellow-bellied sliders are often confused with eastern river cooters, who also have yellow stripes on the neck and yellow undersides, but the latter lack the green spots characteristic of this species. The yellow belly often has an "s"-shaped yellow stripe on its face. They also have markings shaped like question marks on their bellies. Females of the species reach a larger body size than the males do in the same populations.

The Yellow-bellied Slider is a large, semi-aquatic, basking turtle that can be found resting on logs, stumps, or rocks in sunny, mild weather. It can live for more than 25 years in the wild, and up to 40 years in captivity. This species can mate with the Redeared Slider (Trachemys scripta elegans), producing hybrids that are often sold as pets.

This turtle is considered native to North Carolina, South Carolina, and Virginia. It has expanded its range, with established populations now found in Arizona, California,

Florida, and Pennsylvania. Other states, including New Mexico, New York, and Virginia have collected individual turtles, but it is yet unknown if established populations exist  in these states. In Pennsylvania, the Yellow-bellied Slider has been reported in the Lake Erie, Ohio, Susquehanna,

and Delaware River watersheds.

11-6-2018 MONTE CORONA, VALENCIA - ORANGE FEATHERLEG DAMSELFLY (Platycnemis acutipennis)

Platycnemis acutipennis, known as the orange featherleg or the orange white-legged damselfly, is a species of damselfly in the family Platycnemididae.

Platycnemis acutipennis is the only European damselfly which combines an orange-red abdomen and blue eyes. The male has moderately wide hind tibias (wider in both P. pennipes and P. latipes; and the males of both those species have blue abdomens). The thorax is buff-coloured with black stripes. There is an orange spot near the tip of each wing. The sexes are similar.

Platycnemis acutipennis lives in fresh water, either still or up to moderately fast-flowing.

Platycnemis acutipennis is common and widely distributed across the southwest of Europe including Portugal, Spain, and France; it is endemic to that area. There are however some recent records from Germany.
