%20(Turdus%20merula)%2020.jpg)
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.

19-5-2021 MONTE CORONA, VALENCIA - CITRONELLA ANT (Subgenus Lasius)
Lasius is a genus of formicine ants. The type species for this genus is the black garden ant, Lasius niger. Other major members, which live in drier heathland, are the cornfield ant, L. neoniger, and L. alienus. Other species include the temporary social parasites of the L. mixtus group and the hyper-social parasite L. fuliginosus. Lasius flavus is also a commonly seen species, building grassy hillocks in undisturbed pasture. In the Alps, these mounds – always aligned east to catch the first rays of the rising sun – have been traditionally used by goatherds as natural compasses.[citation needed] Species in the subgenus Acanthomyops, in particular L. interjectus and L. claviger, are commonly known as citronella ants due to their citronella-like smell.
Several species in this genus are noted to be social parasites. Some species such as Lasius latipes and Lasius murphyi are noted to have their mating flights in mid-late summer and invade other colonies of Lasius, primarily Lasius neoniger. The queens of species Lasius orientalis and Lasius umbratus have been observed using chemical signals to invade other Lasius colonies and trick the workers to kill the residing queen, accepting the invading queen as their own. Other species, such as Lasius claviger, are known to overwinter and invade colonies in the spring.

17-5-2021 PEGO MARJAL, ALICANTE - WHINCHAT ( Saxicola rubetra)
The whinchat (Saxicola rubetra ) is a small migratory passerine bird breeding in Europe and western Asia and wintering in central Africa. At one time considered to be in the thrush family, Turdidae, it is now placed in the Old World flycatcher family, Muscicapidae. Both sexes have a strong supercilium, brownish upper parts mottled darker, a pale throat and breast, a pale buff to whitish belly, and a blackish tail with white bases to the outer tail feathers, but in the breeding season, the male has an orange-buff throat and breast.
The whinchat is a solitary species, favouring open grassy country with rough vegetation and scattered small shrubs. It perches in elevated locations ready to pounce on the insects and other small invertebrates that form its diet. The nest is built by the female on the ground in coarse vegetation, with a clutch of four to seven eggs being laid. The hen incubates the eggs for about thirteen days and then both parents feed the nestlings.
Fledging takes place about eighteen days after hatching and the parents continue to feed the young for another fortnight. Moulting takes place in late summer before the migration southwards, and again on the wintering grounds in Africa before the migration northwards in spring. The whinchat is a common species with a wide range and the International Union for Conservation of Nature has classified it as being of "least concern".
The Whinchat is largely solitary, forming small family groups in autumn. It exhibits a typical behavior of perching on elevated spots to scan for food and display territorial signals. Breeding occurs in late April and May, with the nest built on the ground by the female. Both parents feed the young, which fledge at about eighteen days old and remain dependent for another fortnight.
The Whinchat's main call is a soft "hue-tac-tac," with the male's song being a whistling, crackly but soft melody, often including mimetic phrases from other bird species' songs. The song is used for breeding from April to July and is occasionally heard on the wintering grounds.
Nesting occurs in dense low vegetation, with the female laying a clutch of four to seven eggs. Incubation lasts about thirteen days, and fledging takes place around eighteen days after hatching. The species is known to breed once they reach one year of age.
The Whinchat can be confused with the European stonechat or the Siberian stonechat, but it can be distinguished by its conspicuous supercilium, whiter belly, and longer wingtips, which are adaptations to its long-distance migration.
The diet consists mainly of insects and other small invertebrates, with occasional fruit consumption. Whinchats perch on elevated spots to make sallies for ground insects or flying insects, displaying their white tail and wing flashes while perched.
The Whinchat is classified as "Least Concern" by the IUCN, though some populations, particularly in Western Europe, are in decline due to agricultural intensification. Conservation efforts focus on maintaining suitable habitat and mitigating the impacts of land use changes.

5-5-2021 BONAIRE, VALENCIA - 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.
16-5-2021 MONTAVERNER, VALENCIA - EUROPEAN STONECHAT (MALE) (Saxicola rubicola)
The European stonechat, Saxicola rubicola, is a small, charming passerine bird, once thought to be a member of the thrush family but now placed within the Old World flycatcher family, Muscicapidae. This species exhibits a striking sexual dimorphism, with males donning a black plumage with vibrant orange throats and females wearing a more subdued brown.
Males in their summer plumage are unmistakable with their black heads, orange throats, and white bellies. They also sport a distinctive white half-collar and small white patches on the wings and rump. Females, on the other hand, are predominantly brown with less pronounced white wing patches. Both sexes have notably short wings, which are shorter than those of their migratory relatives.
The European stonechat favors heathlands, coastal dunes, and open grasslands dotted with shrubs, brambles, and heather. These habitats provide the perfect backdrop for their active foraging and breeding behaviors.
This species is widely distributed across Europe, reaching as far east as Ukraine and the South Caucasus, and can also be found in parts of North Africa.
Stonechats are known for their lively presence, often perching conspicuously as they keep a vigilant eye on their surroundings. They exhibit a partial migratory pattern, with some populations moving southward to escape the colder winters.
The male stonechat's song is a delightful, high-pitched twitter, reminiscent of a dunnock's melody. Both sexes communicate with a distinctive call that evokes the sound of two stones being tapped together.
European stonechats are monogamous during the breeding season and commence their reproductive efforts at one year of age. They raise two to three broods per season, with the female constructing the nest and both parents tending to the young.
The European stonechat can be confused with the Siberian stonechat and the African stonechat, but genetic evidence supports their distinction as separate species.
These birds are adept insectivores, gleaning a variety of invertebrates from their environment to sustain themselves and their offspring.

19-5-2019 BUMI HILLS, ZIMBABWE - SOUTHERN WARTHOG (Phacochoerus africanus ssp. sundevallii) PHOTO COURTESY OF MRS VALERIE FISHER
%20PHOTO%20COURTESY%20OF%20MRS%20VALERIE%20FISHER%2020.jpg)
The common warthog is a medium-sized species, with a head-and-body length ranging from 0.9 to 1.5 m (2 ft 11 in to 4 ft 11 in), and shoulder height from 63.5 to 85 cm (25.0 to 33.5 in). Females, at 45 to 75 kg (99 to 165 lb), are smaller and lighter than males, at 60 to 150 kg (130 to 330 lb).[4][5] A warthog is identifiable by the two pairs of tusks protruding from the mouth and curving upwards. The lower pair, which is far shorter than the upper pair, becomes razor-sharp by rubbing against the upper pair every time the mouth is opened and closed. The upper canine teeth can grow to 25.5 cm (10.0 in) long and have a wide elliptical cross section, being about 4.5 cm (1.8 in) deep and 2.5 cm (0.98 in) wide. A tusk will curve 90° or more from the root, and will not lie flat on a table, as it curves somewhat backwards as it grows. The tusks are not used for digging, but are used for combat with other hogs and in defense against predators – the lower set can inflict severe wounds.
%20PHOTO%20COURTESY%20OF%20MRS%20VALERIE%20FISHER%2021.jpg)
Common warthog ivory is taken from the constantly growing canine teeth. The tusks, particularly the upper set, work in much the same way as elephant tusks with all designs scaled down. Tusks are carved predominantly for the tourist trade in eastern and southern Africa.[citation needed]
The head of the common warthog is large, with a mane down the spine to the middle of the back. Sparse hair covers the body. Its color is usually black or brown. Tails are long and end with a tuft of hair. Common warthogs do not have subcutaneous fat and the coat is sparse, making them susceptible to extreme environmental temperatures.
As of 1999, the common warthog population in southern Africa was estimated to be about 250,000. Typical densities range between 1 and 10 km2 (0.39 and 3.86 sq mi) in protected areas, but local densities of 77 km2 (30 sq mi) were found on short grass in Nakuru National Park in Kenya. The species is susceptible to drought and hunting (especially with dogs), which may result in localized extinctions. The common warthog is present in numerous protected areas across its extensive range.
15-5-2021 RIO SERPIS GANDIA, VALENCIA - SPOTLESS STARLING (Sturnus unicolor)
%2020.jpg)
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.
15-5-2021 RIO SERPIS GANDIA, VALENCIA - LITTLE EGRET (Egretta garzetta)
The little egret (Egretta garzetta) is a species of small heron in the family Ardeidae. It is a white bird with a slender black beak, long black legs and, in the western race, yellow feet. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. It breeds colonially, often with other species of water birds, making a platform nest of sticks in a tree, bush or reed bed. A clutch of three to five bluish-green eggs is laid and incubated by both parents for about three weeks. The young fledge at about six weeks of age.
Its breeding distribution is in wetlands in warm temperate to tropical parts of Asia, Africa, Australia, and Europe. A successful colonist, its range has gradually expanded north, with stable and self-sustaining populations now present in the United Kingdom.
In warmer locations, most birds are permanent residents; northern populations, including many European birds, migrate to Africa and southern Asia to over-winter there. The birds may also wander north in late summer after the breeding season, and their tendency to disperse may have assisted in the recent expansion of the bird's range. At one time common in Western Europe, it was hunted extensively in the 19th century to provide plumes for the decoration of hats and became locally extinct in northwestern Europe and scarce in the south. Around 1950, conservation laws were introduced in southern Europe to protect the species and their numbers began to increase. By the beginning of the 21st century the bird was breeding again in France, the Netherlands, Ireland and Britain. Its range is continuing to expand westward, and the species has begun to colonise the New World; it was first seen in Barbados in 1954 and first bred there in 1994. The International Union for Conservation of Nature has assessed the bird's global conservation status as being of "least concern".
