7-3-2020 THATTEKAD, INDIA - MALABAR WHISTLING THRUSH (Myophonus horsfieldii)
The Malabar whistling thrush (Myophonus horsfieldii) is a whistling thrush in the family Muscicapidae. The bird has been called whistling schoolboy for the whistling calls that they make at dawn that have a very human quality. The species is a resident in the Western Ghats and associated hills of peninsular India including central India and parts of the Eastern Ghats.
Malabar whistling thrushes are usually found in dark undergrowth in dense riverine forest. They typically forage in the margins, beds and adjacent ground of rocky hill streams and rivers in forest, secondary growth and plantations from foothills up to 2200 m above sea level but reach the plains in the rainy season. The species is found all along the Western Ghats south of the Surat Dangs. They are also found along the Satpura range to Chhattisgarh, northwestern Orissa (Surguja and Simlipal National Park), and locally in the Eastern Ghats. Populations are not migratory but are known to disperse widely in winter. An individual that was ringed in Mahabaleshwar in the summer of 1972 was recovered in the winter of 1976 in Sampaje, Coorg. Although historically recorded twice from Mount Abu, more recent surveys have not recorded the bird or suitable habitat in that location.
7-3-2020 THATTEKAD, INDIA - BROWN SHRIKE (Lanius cristatus)
The brown shrike (Lanius cristatus) is a bird in the shrike family that is found mainly in Asia. It is closely related to the red-backed shrike (L. collurio) and isabelline shrike (L. isabellinus). The genus name, Lanius, is derived from the Latin word for "butcher", and some shrikes are also known as "butcher birds" because of their feeding habits. The specific cristatus is Latin for "crested", used in a broader sense than in English. The common English name "shrike" is from Old English scríc, "shriek", referring to the shrill call.
Like most other shrikes, it has a distinctive black "bandit-mask" through the eye and is found mainly in open scrub habitats, where it perches on the tops of thorny bushes in search of prey. Several populations of this widespread species form distinctive subspecies which breed in temperate Asia and migrate to their winter quarters in tropical Asia. They are sometimes found as vagrants in Europe and North America.

6-3-2020 RAIPUR , INDIA - ROSE COLOURED STARLING (Pastor roseus)
%2010.jpg)
The rosy starling (Pastor roseus) is a passerine bird in the starling family, Sturnidae, also known as the rose-coloured starling or rose-coloured pastor. The species was recently placed in its own monotypic genus, Pastor, and split from Sturnus. This split is supported by recent studies, though other related species within its new genus are not yet known for certain.
The genus name Pastor, and the old English name come from the Latin pastor, "shepherd", and by extension a pastor. The specific roseus is Latin for "rose-coloured".
Formerly, some authorities also considered the maroon oriole to be a species within the genus Pastor.

29-2-2020 SAN CARLOS PARQUE, MADRID - EURASIAN TREE SPARROW (MALE)
%2020.jpg)
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.
The Eurasian tree sparrow can be confused with the house sparrow, but the latter has a grey, not brown, crown and lacks the distinctive face pattern of the tree sparrow.
29-2-2020 SAN CARLOS PARQUE, MADRID - EUROPEAN RABBIT (Oryctolagus cuniculus)
%2021.jpg)
The European rabbit is smaller than the European hare and Mountain hare and lacks black ear tips, as well as having proportionately shorter legs. The fur of the European rabbit is generally greyish-brown, but this is subject to much variation. The guard hairs are banded brown and black, or grey, while the nape of the neck and scrotum are reddish. The chest patch is brown, while the rest of the underparts are white or grey. A white star shape is often present on kits' foreheads but rarely occurs in adults. The whiskers are long and black, and the feet are fully furred and buff-coloured. The tail has a white underside, which becomes prominent when escaping danger. This may act as a signal for other rabbits to run. Moulting occurs once a year, beginning in March on the face and spreading over the back. The underfur is completely replaced by October-November. The European rabbit exhibits great variation in colour, from light sandy to dark grey and completely black. Such variation depends largely on the amount of guard hairs relative to regular pelage.
European rabbits are found in southwestern Europe (including Portugal, Spain, and western France) and in northwest Africa (including Morocco and Algeria). Their ideal habitat consists of short grasslands with secure refuge (such as burrows, boulders, hedgerows, scrub, and woodland) near feeding areas. In large coniferous plantations, European rabbits only occur in peripheral areas and along fire breaks and rides.
%2020.jpg)
European rabbits are herbivores (graminivores) and coprophages. They eat a wide variety of herbage, especially grasses, favoring the young, succulent leaves and shoots of the most nutritious species. Hungry rabbits in winter may eat tree bark and blackberries. Like other leporids, European rabbits also consume their own fecal pellets, which are filled with protein-rich bacteria.
European rabbits exhibit an interesting mating system; dominant bucks are polygynous, whereas lower-status individuals (both bucks and does) often form monogamous pairs. Rabbits signal their readiness to mate by marking other animals and inanimate objects with an odoriferous substance secreted through a chin gland; this process is known as "chinning". The breeding season usually takes place from January to August. Does give birth to 3-7 kittens after the gestation period of 30 days. Shortly before giving birth, the doe will construct a separate burrow known as a "stop" or "stab", generally in an open field away from the main warren. These breeding burrows are typically a few feet long and are lined with grass and moss as well as fur plucked from the doe's belly. The breeding burrow protects the kittens from adult bucks as well as from predators. Kittens are altricial, being born blind, deaf, and furless, and they are totally dependent upon their mother. The young born to the dominant buck and doe enjoy better nesting and feeding grounds; they tend to grow larger and stronger and become more dominant than kittens born to subordinate rabbits. Does nurse their kittens once a night, for only a few minutes. After suckling is complete, the doe seals the entrance to the stop with soil and vegetation. The kittens grow rapidly and their eyes open 11 days after birth. The ears do not gain the power of motion until 10 days of age and can be erected after 13. At 18 days, the kittens begin to leave the burrow and at 4 weeks they are weaned. Young bucks become reproductively mature at four months of age, while does can begin to breed at three to five months.
29-2-2020 SAN CARLOS PARQUE, MADRID - EGYPTIAN GOOSE (Alopochen aegyptiaca)
The Egyptian goose, Alopochen aegyptiaca, is a striking bird, native to Sub-Saharan Africa and the Nile Valley. It is a member of the Anatidae family, which includes ducks, geese, and swans. This species is unique in its appearance, resembling a goose more than a duck when in flight, with a heavy and robust stature. Adults typically measure between 63 to 73 centimeters in height.
Both sexes of the Egyptian goose display identical plumage, though males are generally larger. Plumage tones can vary from grey to brown, not necessarily indicative of age or sex. Mature birds boast a significant white patch on their wings, concealed by wing coverts when at rest but prominently displayed when the bird is agitated or in flight.
The Egyptian goose favors open or semi-open environments, often found near freshwater sources. Its habitat ranges from lowlands to high altitudes, such as the Ethiopian Highlands, up to 4,000 meters above sea level. It avoids dense forests and deserts.
This species is widespread and common in its native range, though numbers have dwindled in the northern Nile Valley. Historically found in southeastern Europe and parts of the Middle East, its presence in these areas has diminished.
The Egyptian goose is largely terrestrial, capable of perching on trees and buildings. It is known for its aggressive territorial behavior, especially during breeding season, and is not hesitant to engage in aerial combat with intruders. The species is monogamous, with both parents caring for their offspring.
The male's call is a subdued, hoarse quack, becoming louder and more rapid when agitated, resembling a steam engine. The female's quack is raucous and frequently heard, particularly when defending her young.
Nesting occurs in a variety of locations, with a preference for holes in mature trees. Both parents incubate the eggs, and the young are capable of foraging for themselves shortly after hatching.
Egyptian geese primarily consume seeds, leaves, grasses, and plant stems. They may also eat small animals such as locusts and worms. Goslings initially feed on small aquatic invertebrates before transitioning to grazing.
The Egyptian goose is classified as Least Concern by the IUCN, indicating a stable population. However, in regions where it has been introduced, it is considered invasive and may pose a threat to native species.

26-2-2020 OLIVA CANAL LES FONTS, VALENCIA - EUROPEAN SERIN (Serinus serinus)
The European serin, or simply the serin (Serinus serinus), is a diminutive member of the finch family, Fringillidae. This sprightly bird is the smallest within its family, closely related to the Atlantic canary. It is characterized by its short tail and a length that spans a mere 11 to 12 centimeters. The serin's plumage is a tapestry of nature's palette, with upper parts dappled in dark-streaked greyish green and a conspicuous yellow rump. The underparts are a canvas of yellow breast and white belly, both adorned with heavy streaks.
When attempting to identify the European serin, look for the male's radiant yellow face and breast, which stand out against the greenish backdrop of its feathers. The male also boasts yellow wing bars and yellow tail sides, which can be quite helpful in distinguishing it from similar species. Both sexes share a buzzing trill of a song that resonates through their Mediterranean habitats.
The European serin is partial to open woodland and cultivated areas, often with a sprinkling of conifers. These environments provide the perfect backdrop for breeding and foraging.
This species has a breeding range that extends across southern and central Europe and into North Africa. Populations along the southern and Atlantic coasts tend to be resident, while those in the north are migratory, seeking warmer climates in southern Europe during the winter months.
Outside of the breeding season, the European serin is a sociable creature, forming flocks that may sometimes mingle with other finch species. It is an active and often conspicuous bird, its presence easily announced by its distinctive trill.
The serin's song is a distinctive buzzing trill, a sound that becomes part of the ambient music in regions where these birds are common.
The European serin weaves its nest within the shelter of a shrub or tree, where it lays a clutch of 3 to 5 eggs. The chosen breeding habitats are often areas of open woodland and cultivation, with a preference for some conifers.
The diet of the European serin is predominantly seeds, but it does not shy away from including insects during the breeding season, providing essential protein for its young.
The IUCN Red List categorizes the European serin as Least Concern, indicating that, for now, this species does not face any imminent threats to its survival.
