27-10-2015 MONTE CORONA - BLACK REDSTART (MALE) (Phoenicurus ochruros)

The adult male of this species is overall dark grey to black on the upperparts and with a black breast; the lower rump and tail are orange-red, with the two central tail feathers dark red-brown. The belly and undertail are either blackish-grey (western subspecies) or orange-red (eastern subspecies); the wings are blackish-grey with pale fringes on the secondaries forming a whitish panel (western subspecies) or all blackish (eastern subspecies). The female is grey (western subspecies) to grey-brown (eastern subspecies) overall except for the orange-red lower rump and tail, greyer than the common redstart; at any age, the grey axillaries and underwing coverts are also distinctive. There are two distinct forms in first calendar year males at least in western subspecies, with the first ('carei') being similar to females and the second ('paradoxus') approaching adult males but lacking the whitish wing panel that does only develop during post-breeding molt of wing feathers in the second calendar year. This second form is much rarer than the first.

Black redstarts breed in south and central Europe and Asia and north-west Africa, from Great Britain and Ireland (where local) south to Morocco, east to central China. They are resident in the milder parts of their range, but north-eastern birds migrate to winter in southern and western Europe and Asia, and north Africa. In some areas, birds that breed in mountains move to lower elevations in winter. Black redstarts inhabit stony ground in mountains, particularly cliffs and stony slopes with xerophytic vegetation. They are also found in villages, and urban areas and often occur in large industrial complexes that have bare areas and cliff-like buildings.

Black redstarts are diurnal birds. They spend daytime hours searching for food or perching in trees or bushes. They usually feed on the ground hopping around searching for insects or catching passing insects in flight, and may also use a “sit-and’wait” tactic. During winter Black redstarts are usually solitary but may be seen in pairs or small groups. With the start of the breeding season, they spend time in mated pairs and become territorial. Male Black redstarts have a rattling song and a ‘tick’ call.

18-10-2015 ONGAR, ESSEX - EASTERN GREY SQUIRREL (Sciurus carolinensis)

Europe's grey squirrels (Sciurus carolinensis) originated in North America, where they are known as eastern gray squirrels (to differentiate from western gray squirrels). They eat large seeds, flowers, buds, fruits, fungi, some insects and occasionally bird eggs.

They were first introduced into England, in a concerted way, in 1876, and through rapidly growing population and further introductions they spread to the rest of Great Britain by the early to mid-20th century. The eastern grey squirrel was introduced to Continental Europe in 1948 and has quickly taken advantage of Europe's food sources, habitats and lack of predators for grey squirrels. Genetic studies have shown that human intervention-- released pets and intentional dispersal--may play a much larger role in the spread of grey squirrels than previously believed.

The native squirrel in Europe is the red squirrel (Sciurus vulgaris). Both species have similar diets, use similar locations of the environment and have similar activity patterns; however, there is no evidence of noticeable aggression between the two species. These eastern grey squirrels are considered an invasive species in Europe because of their presence contributing to the displacement of the red squirrels.

The invasion of the grey squirrel in the United Kingdom can be classified as a Disease Mediated Invasion (DMI). More specifically, the invasion of the grey squirrels and displacement of the red squirrels can be described by "spillover DMI", which is defined as a non-native species bringing diseases with them into the new area that will infect the native species. Spillover is especially an issue of when the invading species is morphologically similar to the native one. This can have devastating effects.

They were first introduced into England, in a concerted way, in 1876, and through rapidly growing population and further introductions they spread to the rest of Great Britain by the early to mid-20th century.

The first reported introduction of grey squirrels in continental Europe was in 1948, and they were taken to Stupinigi, Italy, where there is still a growing population. In Ireland, however, Lord Longford was said to have introduced the American squirrels into his estate in 1911. Then in 1966, five squirrels were introduced to Nervi, Italy in the park of Genoa. Later in 1994, three pairs were again released to a park in Trecate but were captured and removed in 1996. As stated before, not all grey squirrel introductions were intentional. For example, in 1966 two females and one male escaped from a game farm on Vancouver Island.

Almost 80% of known grey squirrel introductions worldwide resulted in successful establishment in the new area. Typically, grey squirrels do not need large numbers to start a new population. From studying all of the known successful introductions of this species, 71.4% used fewer than 10 individuals. This efficiency in the spread of grey squirrels can be explained by the "enemy release hypothesis", which is when the invading species has better survival because its natural predators are not present. Also, natural parasites typically are not present in the area that the species has been introduced or has invaded. Because the grey squirrel poses such a threat to the trees and red squirrel in Europe, there is great effort to stop the further spread of the grey squirrels.

19-10-2015 LAKELAND, THURROCK - MALLARD (FEMALE) (Anas platyrhynchos)

The mallard (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. Mallards live in wetlands, eat water plants and small animals, and prefer to congregate in flocks of varying sizes. Unlike many waterfowl, mallards are considered an invasive species in some regions. It is a very adaptable species, being able to live and even thrive in urban areas. This species is the main ancestor of most breeds of domestic duck, and its naturally evolved wild gene pool has been genetically polluted by the domestic and feral mallard populations.

The magnificent mallard is one of the most recognizable bird species around the world. When flying, the bird displays a purplish-blue speculum, which is outlined in white. Males of this species are particularly colorful. Breeding males have a yellow beak, dark brown chest, black and white tail as well as bright green head and neck. They exhibit a white ring at the base of their neck. In addition, the sides of breeding males and most of their wings are gray. On the other hand, the plumage of female mallards and non-breeding males is less vivid and colorful. The overall plumage of female mallards is spotted with tan and brown patches, and the head is a lighter tan, showing dark bands near the crown and eyes. Females have orange-colored beaks, covered with dark spots. Females and non-breeding males generally look alike, though the latter have yellowish beaks.

19-10-2015 LAKELAND, THURROCK - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

The Great cormorant (Phalacrocorax carbo) is a widespread member of the cormorant family of seabirds. Many fishermen see in the Great cormorant a competitor for fish. Because of this, it was hunted nearly to extinction in the past but luckily due to conservation efforts, its numbers increased.

The Great cormorant is a large black bird, but there is a wide variation in size in the species' wide range. Males are typically larger and heavier than females. It has a longish tail and yellow throat patch. Adults have white patches on the thighs and on the throat in the breeding season. In European waters, the Great cormorant can be distinguished from the Common shag by its larger size, heavier build, thicker bill, lack of a crest, and plumage without any green tinge. In eastern North America, it is similarly larger and bulkier than the Double-crested cormorant, and the latter species has more yellow on the throat and bill and lack the white thigh patches frequently seen on great cormorants.

Great cormorants occur throughout Europe, Asia, Australia, Africa, and northeastern coastal North America. They may be both resident and migratory. Throughout the year in some areas, large groups remain within the breeding range. Greta cormorants frequent open marine environments and inland waters. They inhabit sandy or rocky sheltered coasts and estuaries and are rarely seen any distance from the coast. This species breeds on cliffs and inshore islands, among boulders and man-made structures. Birds that nest inland will breed on trees, bushes, and reedbeds, and even on bare ground.

Great cormorants are active during the day and are social birds, usually leaving roosts to forage early in the morning and returning within an hour. Little time each day is spent foraging, although parents with young tend to forage for longer. Much of the day is spent resting and preening near foraging areas or at roosts. Great cormorants generally are not aggressive towards one another, apart from at nest sites, where they exhibit territorial behavior. There may be dominance hierarchies. Outside of the breeding season, they usually gather in mixed-age, mixed-sex groups.

Great cormorants are monogamous, with pairs sometimes reuniting in subsequent years. The male chooses the nest site, displaying to attract the female by waving his wings up and down and flashing his white rump patch. He will also swing his head from side to side while holding his tail erect and calling loudly. The female responds by swinging her head slightly and “purring”. This species breeds at any time, depending on food resources. Breeding takes place in colonies of as many as 2,000 pairs, although colonies of a smaller size are typical. Colonies are often located close to other species, like darters, herons, and spoonbills. The parents build their nest with reeds, sticks, and seaweeds on a cliff, in a tree, or in a bush, according to the region. Often a nest is reused. 2 to 6 eggs are laid, with an average of 3-4. The parents share the incubation for 27 to 31 days. The altricial chicks hatch at intervals and fledge at about 50 days old. They remain with their parents for 50 or more days, relying on them for food. The young start to breed between 2 and 4 years old, typically when 3 years old.

18-10-2015 MALDON, ESSEX - MALLARD (FEMALE) (Anas platyrhynchos)

The Mallard is a large and heavy-looking duck. It has a long body, and a long and broad bill. The male has a dark green head, a yellow bill, is mainly purple-brown on the breast and grey on the body. The female is mainly brown with an orange bill. Mallards breed in all parts of the UK in summer and winter, wherever there are suitable wetland habitats, although it is rarer in upland areas. In the UK, Mallards may be resident breeders or migrants – many of the birds that breed in Iceland and northern Europe spend the winter here.

3-11-2015 GANDIA LA VITAL - HOUSE SPARROW (FEMALE) (Passer domesticus)

The House sparrow (Passer domesticus) is a small passerine bird found in most parts of the world. The extent of its range makes it the most widely distributed wild bird on the planet. Because of its numbers, ubiquity, and association with human settlements, the House sparrow is culturally prominent. It is extensively, and usually unsuccessfully, persecuted as an agricultural pest. It has also often been kept as a pet and was a food item. Though it is widespread and abundant, its numbers have declined in some areas.

House sparrows are native to most of Europe, the Mediterranean Basin, a large part of Asia, and parts of North Africa. These birds are strongly associated with human habitation and can live in urban or rural settings. They are found in widely varied habitats and climates but typically avoid extensive woodlands, grasslands, and deserts away from human development. The only terrestrial habitats that House sparrows do not inhabit are dense forests and tundra.

The plumage of the House sparrow is mostly different shades of grey and brown. The sexes exhibit strong dimorphism: the female is mostly buffish above and below, while the male has boldly colored head markings, a reddish back, and grey underparts. The male has a dark grey crown from the top of its bill to its back, and chestnut brown flanking its crown on the sides of its head. It has black around its bill, on its throat, and on the spaces between its bill and eyes (lores). It has a small white stripe between the lores and crown and small white spots immediately behind the eyes (postoculars), with black patches below and above them. The underparts are pale grey or white, as are the cheeks, ear coverts, and stripes at the base of the head. The upper back and mantle are a warm brown, with broad black streaks, while the lower back, rump, and upper tail coverts are greyish brown. The male is duller in fresh nonbreeding plumage, with whitish tips on many feathers. Wear and preening expose many of the bright brown and black markings, including most of the black throat and chest patch, called the "bib" or "badge". The male's bill is dark grey, but black in the breeding season. The female has no black markings or grey crowns. Its upperparts and head are brown with darker streaks around the mantle and a distinct pale supercilium. Its underparts are pale grey-brown. The female's bill is brownish-grey and becomes darker in breeding plumage approaching the black of the male's bill. Juveniles are similar to adult female, but deeper brown below and paler above, with paler and less defined supercilia. Juvenile males tend to have darker throats and white postoculars like adult males, while juvenile females tend to have white throats. The bills of young birds are light yellow to straw, paler than the female's bill.

18-10-2015 MALDON, ESSEX - MUTE SWAN (JUVENILE) (Cygnus olor)

The plumage of Mute swans is white, while the legs are dark grey. The beak is bright orange, with black around the nostrils and a black nail. Males are larger than females and have a larger knob on their bills. Young birds (cygnets) are not the bright white of mature adults, and their bill is dull greyish-black, not orange, for the first year. The down may range from pure white to grey to buff, with grey/buff the most common. The cygnets grow quickly, reaching a size close to their adult size in approximately 3 months after hatching. Cygnets typically retain their grey feathers until they are at least one year old, with the down on their wings having been replaced by flight feathers earlier that year. All Mute swans are white at maturity, though the feathers (particularly on the head and neck) are often stained orange-brown by iron and tannins in the water.

Mute swans breed in north-central Europe, the British Isles, and north-central Asia. They are partially migratory throughout northern latitudes in Europe and Asia, as far south as North Africa and the Mediterranean. Mute swans prefer well-sheltered bays, lakes, ponds, and open marshes.

Mute swans are usually very territorial with just a single pair on smaller lakes, though in a few locations where a large area of suitable feeding habitat is found, they can be colonial. Non-mated juveniles up to 3-4 years old commonly form larger flocks, which can total several hundred birds, often at regular traditional sites. Once the adult birds are mated they seek out their own territories and often live close to ducks and gulls. Mute swans feed during the daytime, by dabbling on the water surface and upending. While swimming they hold their neck with a graceful curve, the bill pointing downward. Mute swans are not very vocal but they do make a variety of sounds, often described as "grunting, hoarse whistling, and snorting noises." During a courtship display, they utter a rhythmic song. Mute swans usually hiss at competitors or intruders trying to enter their territory. The most familiar sound of these birds is the vibrant throbbing of the wings in flight which is unique to the species and can be heard from a range of 1 to 2 km (0.6 to 1 mi), indicating its value as a contact sound between birds in flight. Cygnets are especially vocal and communicate through a variety of whistling and chirping sounds when content, as well as a harsh squawking noise when distressed or lost. Mute swans can be very aggressive in defense of their nests and are highly protective of their mate and offspring. Most defensive acts begin with a loud hiss and, if this is not sufficient to drive off the predator or intruder, are followed by a physical attack. Swans attack by striking at the threat with bony spurs in their wings, accompanied by biting with their large bill.

Mute swans are mainly herbivores. They feed on a wide range of vegetation, both submerged aquatic plants which they reach with their long necks, and by grazing on land. The food commonly includes agricultural crop plants such as oilseed rape and wheat. They will also feed on small proportions of aquatic insects, fish, and frogs.

Mute swans are serially monogamous and remain together for at least one season. Males may, however, have four mates, and even "divorce" to have another female. Mute swans nest on large mounds that they build with waterside vegetation in shallow water on islands in the middle or at the very edge of a lake. They often reuse the same nest each year, restoring or rebuilding it as needed. Male and female swans share the care of the nest. The breeding starts in March or early April. Nest building is done by both parents, with the male bringing the nest material to the female. Females lay 5 to 12 eggs, and incubation lasts around 36-38 days, which is done mainly by the female while her mate defends the territory. The cygnets hatch over a period of 26 hours and both parents look after the young. The female broods the cygnets and they often ride on their mother's back from the age of 10 days. Two months after hatching the young are fully feathered. They stay with their parents until the following spring and breeding season. At 3 years of age, they become reproductively mature and start to breed.

18-10-2015 MALDON, ESSEX - LITTLE EGRET (Egretta garzetta)

https://en.wikipedia.org/wiki/Little_egret

14-10-2015 VALENCIA BIOPARC - EGYPTIAN GOOSE (Alopochen aegyptiaca)

The Egyptian goose (Alopochen aegyptiaca) is an African member of the Anatidae family including ducks, geese, and swans. Because of their popularity chiefly as an ornamental bird, the species has also been introduced to Europe, the United States and elsewhere outside their natural range. Egyptian geese were regularly represented in ancient Egyptian art.

The Egyptian goose is believed to be most closely related to the shelducks (genus Tadorna) and their relatives, and is placed with them in the subfamily Tadorninae. It is the only extant member of the genus Alopochen, which also contains closely related prehistoric and recently extinct species. mtDNA cytochrome b sequence data suggest that the relationships of Alopochen to Tadorna need further investigation.

It swims well and appears heavy in flight, more like a goose than a duck, hence the English name. On average, they are 63–73 cm (25–29 in) tall.

The sexes of this species are identical in plumage but the males are usually somewhat larger. They vary greatly in plumage tone, with some birds greyer and others browner, but this variation has not been observed to be sex- or age-related. A large part of the wings of mature birds is white, but the white is hidden by the wing coverts when at rest. When it is aroused, either in alarm or aggression, the white is displayed.

Egyptian geese in the wild can live for up to 15 years, while captive individuals have been recorded reaching an age of 35.

The voices and vocalisations of the sexes differ, the male having a hoarse, subdued duck-like quack which seldom sounds unless it is aroused, as well as a louder, breathy call which is performed in a rapid sequence, sounding somewhat like a steam engine. The female has a far noisier raucous quack that frequently sounds in aggression when tending her young. The male Egyptian goose attracts its mate with an elaborate, noisy courtship display that includes honking, neck stretching and feather displays.

The Egyptian goose is native to Sub-Saharan Africa and the Nile Valley, where it is widespread and common to abundant, though it has become scarce in the northern Nile Valley. It is found in open or semi-open habitats, typically near fresh water, ranging from lowlands to 4,000 m (13,000 ft) above sea level in the Ethiopian Highlands, and largely absent from dense forests and deserts. While not breeding, it disperses somewhat, sometimes making longer migrations northwards into the arid regions of the Sahel, and occasionally even reaching the North African nations of Algeria and Tunisia, historically a more frequent part of its range.

It was found in southeastern Europe (up to the lower Danube Valley and southern Hungary) until the early 1700s, and in parts of Turkey and the western Middle East until the early 1900s (and has since re-established through escaped captives), but its historical ranges in these places is incompletely known and the reason for the disappearances is also unknown.

This is a largely terrestrial species, which will also perch on trees and buildings.

This species will nest in a large variety of situations, especially in holes in mature trees in parkland. The female builds the nest from reeds, leaves and grass and both parents take turns incubating the eggs. Egyptian geese usually mate for life. Both the male and female care for the offspring until they are old enough to care for themselves. Such parental care, however, does not include foraging for the young, which are able forage for themselves upon hatching.

Egyptian geese typically eat seeds, leaves, grasses and plant stems. Occasionally, they will eat locusts, worms, or other small animals. Until the goslings are a few weeks old and strong enough to graze, they feed largely on small aquatic invertebrates, especially freshwater plankton. As a result, if anoxic conditions lead to the production of botulinum toxin and it gets passed up the food chain via worms and insect larvae insensitive to the toxin, entire clutches of goslings feeding on such prey may die. The parents, who do not eat such organisms to any significant extent, generally remain unaffected.

Both sexes are aggressively territorial towards their own species when breeding and frequently pursue intruders into the air, attacking them in aerial "dogfights". Egyptian geese have been observed attacking aerial objects such as drones that enter their habitat as well. Neighbouring pairs may even kill another's offspring for their own offsprings' survival, as well as for more resources.

In their native range, predators of Egyptian geese include leopards, lions, cheetahs, hyenas, crocodiles and Old World vultures.

14-10-2015 VALENCIA BIOPARC - AFRICAN BLACK DUCK (Anas sparsa)

The African black duck (Anas sparsa) is a species of duck of the genus Anas. It is genetically closest to the mallard group, but shows some peculiarities in its behavior and (as far as they can be discerned) plumage; it is accordingly placed in the subgenus Melananas pending further research.

The African black duck is mainly found in eastern and southern sub-Saharan Africa from South Africa north to South Sudan and Ethiopia with outlying populations in western equatorial Africa, in southeast Nigeria, Cameroon and Gabon.

It is an omnivore that feeds off of larvae and pupae usually found under rocks, aquatic animals, plant material, seeds, small fish, snails, and crabs.

Though it likes to stay in rivers and streams during the day it prefers large open waters during the night. This duck likes water in the wooded hills of Africa and hides its nest near running water. Also the African black duck makes its cup shaped nest of driftwood and matted grass. Though it builds its nest near water it is always above flood level and on the ground.

This species has an extremely large range and can be found in Angola, Botswana, Burundi, Cameroon, The Democratic Republic of the Congo, Equatorial Guinea, Ethiopia, Gabon, Guinea, Kenya, Malawi, Mozambique, Namibia, Nigeria, Rwanda, South Africa, South Sudan, Sudan, Tanzania, Uganda, Zambia, and Zimbabwe.HabitatThis species prefers fast-flowing shallow rivers and streams with rocky substrates, particularly in wooded and mountainous country up to 4,250 m (13,9436 ft.).PopulatioThe total population is unknown but scientists believe there are at least 10,000 mature individuals. The population is decreasing but is not severely fragmented.

14-10-2015 VALENCIA BIOPARC - YELLOW BILLED STORK (Mycteria ibis)

The yellow-billed stork (Mycteria ibis), sometimes also called the wood stork or wood ibis, is a large African wading stork species in the family Ciconiidae. It is widespread in regions south of the Sahara and also occurs in Madagascar.

his medium-sized stork stands 90–105 cm (35–41 in) tall. Its body is white with a short black tail that is glossed green and purple when freshly moulted. The bill is deep yellow, slightly decurved at the end and with a rounder cross-section than in other stork species outside the Mycteria. Feathers extend onto the head and neck just behind the eyes, with the face and forehead being covered by deep red skin. Both sexes are similar in appearance, but the male is larger and has a slightly longer heavier bill. Males and females weigh approximately 2.3 kg (5.1 lb) and 1.9 kg (4.2 lb) respectively.

Colouration becomes more vivid during the breeding season. In the breeding season, the plumage is coloured pink on the upperwings and back; the ordinarily brown legs also turn bright pink; the bill becomes a deeper yellow and the face becomes a deeper red.

Juveniles are greyish-brown with a dull, partially bare orange face and a dull yellowish bill. The legs and feet are brown and feathers are blackish-brown all over. At fledging, salmon-pink colouration in the underwings begins to develop and after about one year, the plumage is greyish-white. Flight feathers on the tail and wing also become black. Later, the pink colouration typical of adult plumage appears.

These storks walk with a high-stepped stalking gait on the ground of shallow water. Their approximate walking rate has been recorded as 70 steps per minute. They fly with alternating flaps and glides, with the speed of their flaps averaging 177–205 beats per minute. They usually flap only for short journeys and often fly in a soaring and gliding motion over several kilometres for locomotion between breeding colonies or roosts and feeding sites. By soaring on thermals and gliding by turns, they can cover large distances without wasting much energy. On descending from high altitudes, this stork has been observed to dive deeply at high speeds and flip over and over from side to side, hence showing impressive aerobatics. It even appears to enjoy these aerial stunts.

This species is generally non-vocal, but will utter hissing falsetto screams during social displays in the breeding season. These storks also engage in bill clattering and an audible “woofing” wing beat at breeding colonies Nestlings make a loud continual monotonous braying call to beg parental adults for food.

14-10-2015 VALENCIA BIOPARC - GREY HERON (Ardea cinerea)

The Grey Heron is a distinctive species with grey, black, and white plumage. It is often seen along rivers or lake margins, or standing in flooded fields.

In flight their large size, impressive wingspan, long legs, and folded neck give them an unmistakable silhouette. Largely silent away from colonies, flight is sometimes accompanied by a harsh ‘kraank’ call.

Grey Herons gather to nest in treetop sites called heronries, some of which have been occupied for many decades. These have been monitored in the UK since 1928 through the Heronries Census. Overall the UK's breeding population has increased, with numbers peaking in the early 2000, but with some more recent declines.

Herons are often seen standing as still as a statue on their long thin legs in shallow waters of ponds and lakes patiently waiting for their next meal to swim by. These tall birds spend most of their time alone feeding mainly on fish but can be tempted by the occasional tasty mole! When feeling particularly lazy the heron will visit gardens with ponds for a quick and easy snack. Make sure you look out for these incredible birds in flight, their slow-flapping wings and long legs held out behind make them hard to miss!

The heron is an easily recognised, grey-backed bird, with long legs, a long, white neck, bright yellow bill and a black eyestripe that continues as long, drooping feathers down the neck. Flies with its long legs stretched out, but its neck pulled in.

 

Found throughout town and countryside, on canals, ponds, lakes and rivers across the UK.

 

Herons nest in colonies called 'Heronries', often in the top of trees. Here, they make their large, ungainly nests out of twigs and lay 3-4 eggs. The young will fledge from the nest after about one and half months.

19-10-2015 LAKELAND, THURROCK - MALLARD (MALE) (Anas platyrhynchos)

The mallard (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa.

They exhibit a white ring at the base of their neck. In addition, the sides of breeding males and most of their wings are gray. On the other hand, the plumage of female mallards and non-breeding males is less vivid and colorful. The overall plumage of female mallards is spotted with tan and brown patches, and the head is a lighter tan, showing dark bands near the crown and eyes. Females have orange-colored beaks, covered with dark spots. Females and non-breeding males generally look alike, though the latter have yellowish beaks.

14-10-2015 VALENCIA BIOPARC - SPOTTED THICK NEE (Burhinus capensis)

The spotted thick-knee, which can reach up to 45.5 cm (17.9 in) in height, has long legs and brown-and-white speckled plumage which provides camouflage, making it difficult to spot the bird in the grasslands and savannas where it roams. Its head is large and round with a prominent yellow eye and a short, stout beak. When in flight or standing in a characteristic position with its wings raised, it shows a striking contrasting pattern. Its legs are long and yellow and the tibiotarsal joint is expanded, giving it the name "thick-knee".

It nests on the ground, lining a scrape with grasses, feathers, pebbles and twigs. The female typically lays two eggs, and males and females rear the offspring together, with both bringing food back to the nest. The birds will defend the nest and adopt a defensive pose with wings spread and tail cocked and will even peck an intruder. Sometimes they will fake injuries to lead predators away from the nest.

The spotted thick-knee is native to the grasslands and savannas of sub-Saharan Africa. Its range extends from Senegal, Mali and Mauritania in the west to Ethiopia, Kenya, Tanzania and South Africa in the east and south, and south Yemen.

The spotted thick-knee has a very extensive range, and its population is believed to be stable. For these reasons, the IUCN has rated it as being of "Least Concern".

1-10-2015 MONTE CORONA, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)

The House sparrow (Passer domesticus) is a small passerine bird found in most parts of the world. The extent of its range makes it the most widely distributed wild bird on the planet. Because of its numbers, ubiquity, and association with human settlements, the House sparrow is culturally prominent. It is extensively, and usually unsuccessfully, persecuted as an agricultural pest. It has also often been kept as a pet and was a food item. Though it is widespread and abundant, its numbers have declined in some areas.

The plumage of the House sparrow is mostly different shades of grey and brown. The sexes exhibit strong dimorphism: the female is mostly buffish above and below, while the male has boldly colored head markings, a reddish back, and grey underparts. The male has a dark grey crown from the top of its bill to its back, and chestnut brown flanking its crown on the sides of its head. It has black around its bill, on its throat, and on the spaces between its bill and eyes (lores). It has a small white stripe between the lores and crown and small white spots immediately behind the eyes (postoculars), with black patches below and above them. The underparts are pale grey or white, as are the cheeks, ear coverts, and stripes at the base of the head. The upper back and mantle are a warm brown, with broad black streaks, while the lower back, rump, and upper tail coverts are greyish brown. The male is duller in fresh nonbreeding plumage, with whitish tips on many feathers. Wear and preening expose many of the bright brown and black markings, including most of the black throat and chest patch, called the "bib" or "badge". The male's bill is dark grey, but black in the breeding season. The female has no black markings or grey crowns. Its upperparts and head are brown with darker streaks around the mantle and a distinct pale supercilium. Its underparts are pale grey-brown. The female's bill is brownish-grey and becomes darker in breeding plumage approaching the black of the male's bill. Juveniles are similar to adult female, but deeper brown below and paler above, with paler and less defined supercilia. Juvenile males tend to have darker throats and white postoculars like adult males, while juvenile females tend to have white throats. The bills of young birds are light yellow to straw, paler than the female's bill.

11-10-2015 VILLALONGA RESERVOIR, VALENCIA - GREEN SANDPIPER (Tringa ochropus)

The green sandpiper (Tringa ochropus) is a small wader (shorebird) of the Old World.

The green sandpiper represents an ancient lineage of the genus Tringa; its only close living relative is the solitary sandpiper (T. solitaria). They both have brown wings with little light dots and a delicate but contrasting neck and chest pattern. In addition, both species nest in trees, unlike most other scolopacids.

Given its basal position in Tringa, it is fairly unsurprising that suspected cases of hybridisation between this species and the common sandpiper (A. hypoleucos) of the sister genus Actitis have been reported.

The green sandpiper was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the current binomial name Tringa ochropus. The genus name Tringa is the Neo-Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific ochropus is from Ancient Greek okhros, "ochre", and pous, "foot". The species is monotypic: no subspecies are recognised.

19-3-2015 JURONG, SINGAPORE - CATTLE EGRET (Bubulcus ibis)

The Cattle egret (Bubulcus ibis) is a cosmopolitan species of heron named for its association with cattle. It is the only member of the monotypic genus Bubulcus, although some authorities regard its two subspecies as full species, the Western cattle egret and the Eastern cattle egret. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea.

The Cattle egret is a stocky bird. It has a relatively short, thick neck, a sturdy bill, and a hunched posture. The nonbreeding adult has mainly white plumage, a yellow bill, and greyish-yellow legs. During the breeding season, adults of the nominate western subspecies develop orange-buff plumes on the back, breast, and crown, and the bill, legs, and irises become bright red for a brief period prior to pairing. The sexes are similar, but the male is marginally larger and has slightly longer breeding plumes than the female; juvenile birds lack coloured plumes and have a black bill.

19-3-2015 JURONG, SINGAPORE - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

Global population: 1,400,000 to 2,100,000 individuals. The European breeding population is estimated at 828,000 to 1,030,000 mature individuals 

Wingspan: 121 to 160 cm 

Life span: over 10 years. The oldest Great Cormorant ever recorded was over 21 years old.  

Distinct features: Great Cormorants are large birds with long, thick, necks. Their black plumage has a blue-greenish metallic reflection. Their powerful bills are greyish with white patches around its base. Their legs are dark and long. Males are typically larger and heavier than females. When flying, this seabird can be recognised by its brief glides, breaking its active flight with slightly shallow wingbeats. When in their flock, Great Cormorants fly quite high up, holding a formation. But when alone, they often fly low over the water. Their plumage is not waterproof, so they often stand on rocks, wings outstretched, to dry off after fishing. 

Main prey: This seabird has a diverse diet that includes fish, amphibians, crustaceans and nestling birds. They can occasionally dive to catch their prey, mostly in the benthic zone (the lowest level of a body of water) and above 10 meters. They are usually solitary feeders but can form large fishing flocks in some areas.

The green sandpiper (Tringa ochropus) is a small wader (shorebird) of the Old World.

The green sandpiper represents an ancient lineage of the genus Tringa; its only close living relative is the solitary sandpiper (T. solitaria). They both have brown wings with little light dots and a delicate but contrasting neck and chest pattern. In addition, both species nest in trees, unlike most other scolopacids.

Given its basal position in Tringa, it is fairly unsurprising that suspected cases of hybridisation between this species and the common sandpiper (A. hypoleucos) of the sister genus Actitis have been reported.

This species is a somewhat plump wader with a dark greenish-brown back and wings, greyish head and breast and otherwise white underparts. The back is spotted white to varying extents, being maximal in the breeding adult, and less in winter and young birds. The legs and short bill are both dark green.

It is conspicuous and characteristically patterned in flight, with the wings dark above and below and a brilliant white rump. The latter feature reliably distinguishes it from the slightly smaller but otherwise very similar solitary sandpiper (T. solitaria) of North America.

In flight it has a characteristic three-note whistle.
