29-9-2016 MALDON, ESSEX - EUROPEAN STARLING (FEMALE) (Sturnus vulgaris)

The Common starling (Sturnus vulgaris) is a medium-sized passerine bird in the starling family, Sturnidae. It is a noisy bird, especially in communal roosts and other gregarious situations, with an unmusical but varied song. Its gift for mimicry has been noted in literature including the Mabinogion and the works of Pliny the Elder and William Shakespeare.

The Сommon starling is a medium-sized bird. It has glossy black plumage with a metallic sheen, which is speckled with white at some times of the year. The legs are pink and the bill is black in winter and yellow in summer. Juveniles are grey-brown and by their first winter resemble adults though often retaining some brown juvenile feathering, especially on the head. They can usually be sexed by the color of the irises, rich brown in males, mouse-brown, or grey in females.

Common starlings are native to Eurasia and are found throughout Europe, northern Africa (from Morocco to Egypt), India (mainly in the north but regularly extending further south and extending into the Maldives) Nepal, the Middle East including Syria, Iran, and Iraq and north-western China. Common starlings in the south and west of Europe are mainly resident, although other populations migrate from regions where the winter is harsh. Most birds from northern Europe, Russia, and Ukraine migrate southwestwards or southeastwards. In the autumn, when immigrants are arriving from eastern Europe, many of Britain's common starlings are setting off for Iberia and North Africa.

Common starlings prefer urban or suburban areas, reedbeds, grassy areas such as farmland, grazing pastures, playing fields, golf courses, and airfields where short grass makes foraging easy. They occasionally inhabit open forests and woodlands and are sometimes found in shrubby areas. These birds are also found in coastal areas, where they nest and roost on cliffs and forage amongst the seaweed.

29-9-2016 MALDON, ESSEX - EUROPEAN STARLING (MALE) (Sturnus vulgaris)

The Common starling (Sturnus vulgaris) is a medium-sized passerine bird in the starling family, Sturnidae.

They occasionally inhabit open forests and woodlands and are sometimes found in shrubby areas. These birds are also found in coastal areas, where they nest and roost on cliffs and forage amongst the seaweed.

Common starlings are highly gregarious birds, especially in autumn and winter when huge, noisy flocks may form near roosts. These birds move by walking or running, rather than hopping. Their flight is quite strong and direct; their triangular-shaped wings beat very rapidly, and periodically the birds glide for a short way without losing much height before resuming powered flight. When in a flock, starlings take off almost simultaneously, wheel and turn in unison, form a compact mass, or trail off into a wispy stream, bunch up again, and land in a coordinated fashion. Common starlings feed by day using three types of foraging behavior. "Probing" involves the bird plunging its beak into the ground randomly and repetitively until an insect has been found. "Hawking" is the capture of flying insects directly from the air, and "lunging" is the less common technique of striking forward to catch a moving invertebrate on the ground. Earthworms are caught by pulling from the soil. Common starlings communicate with help of various calls that include a flock call, threat call, attack call, snarl call, and copulation calls. The alarm call is a harsh scream, and while foraging together Common starlings squabble incessantly. They chatter while roosting and bathing, making a great deal of noise that can cause irritation to people living nearby. Their song consists of a wide variety of both melodic and mechanical-sounding noises as part of a ritual succession of sounds. The songsters are more commonly male although females also sing on occasion.

Their song consists of a wide variety of both melodic and mechanical-sounding noises as part of a ritual succession of sounds. The songsters are more commonly male although females also sing on occasion.

Common starlings are both monogamous and polygynous; although broods are generally brought up by one male and one female, occasionally the pair may have an extra helper. Males may mate with a second female while the first is still in the nest. Breeding takes place during the spring and summer. Unpaired males find a suitable cavity and begin to build nests in order to attract single females, often decorating the nest with ornaments such as flowers and fresh green material.

The males sing throughout the construction and even more so when a female approaches his nest. After the pair was formed, the male and female continue to build the nest. Nests may be in any type of hole, common locations include inside hollowed trees, buildings, tree stumps, and man-made nest boxes. Nests are typically made out of straw, dry grass, and twigs with an inner lining made up of feathers, wool, and soft leaves. The female lays 4-5 eggs that are ovoid in shape and pale blue or occasionally white, and they commonly have a glossy appearance. Incubation lasts 13 days and both parents share the responsibility of brooding the eggs. The chicks are born blind and naked. They develop light fluffy down within 7 days of hatching and can see within 9 days. Nestlings remain in the nest for 3 weeks, where they are fed continuously by both parents. After leaving the nest fledglings continue to be fed by their parents for another 1 or 2 weeks. A pair can raise up to three broods per year, although two broods are typical. Within 2 months, most juveniles will have molted and gained their first basic plumage. They acquire their adult plumage the following year.

29-9-2016 MALDON, ESSEX - CARRION CROW (Corvus corone)

The carrion crow (Corvus corone) is a passerine bird of the family Corvidae and the genus Corvus which is native to western Europe and the eastern Palearctic.

The plumage of the Carrion crow is black with a green or purple sheen, much greener than the gloss of the rook. The bill, legs, and feet are also black. There is frequent confusion between the Carrion crow and the rook, another black corvid found within its range. The beak of the crow is stouter and in consequence looks shorter, and whereas in the adult rook the nostrils are bare, those of the crow are covered at all ages with bristle-like feathers. As well as this, the wings of a Carrion crow are proportionally shorter and broader than those of the rook when seen in flight. Juvenile Carrion crows can be identified by their brownish plumage and blue eyes, both of which darken to black and brown as the crow grows older.

Carrion crows are native to western Europe and much of Asia. Birds that live in colder areas may migrate south to spend the winter months. Carrion crows live in a variety of habitats including parks and gardens, cultivated areas, wetlands, forest clearings, woodlands, moors, inshore islands, coastal cliffs, and tidepools.

Carrion crowns are generally solitary but may feed in groups and are often sociable in winter roosts. They are noisy birds, perching on a vantage point such as a building or the top of a tree and calling three or four times in quick succession, with a slight pause between each series of croaks. During each series of calls, a crow may perform an accompanying gesture, raising its shoulders and bowing its head and neck downwards with each caw. Carrion crows are scavengers by nature, which is why they tend to frequent sites inhabited by humans in order to feed on their household waste. They will also harass birds of prey or even foxes for their kills. Carrion crows actively hunt and occasionally co-operate with other crows to make kills, and are sometimes seen catching ducklings for food. Due to their gregarious lifestyle and defensive abilities, Carrion crows have few natural predators. They will actively harass predators and competitors that enter their territory or threaten them or their offspring and will engage in group mobbing behavior as a method to defend themselves.

29-9-2016 HANNINGFIELD RESERVOIR, ESSEX - MALLARD (FEMALE) (Anas platyrhynchos)

The mallard or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa, and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae.  Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.

29-9-2016 LAKELANDS, ESSEX - SPECKLED WOOD BUTTERFLY (Pararge aegeria)

The speckled wood (Pararge aegeria) is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic realm. The species is subdivided into multiple subspecies, including Pararge aegeria aegeria, Pararge aegeria tircis, Pararge aegeria oblita, and Pararge aegeria insula. The color of this butterfly varies between subspecies. The existence of these subspecies is due to variation in morphology down a gradient corresponding to a geographic cline. The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on ecological conditions. The monandrous female must choose which type of male can help her reproduce successfully. Her decision is heavily influenced by environmental conditions.

The average wingspan of both males and females is 5.1 cm (2 in), although males tend to be slightly smaller than females. Furthermore, males possess a row of grayish-brown scent scales on their forewings that is absent in the females. Females have brighter and more distinct markings than males. The subspecies P. a. tircis is brown with pale yellow or cream spots and darker upperwing eyespots. The subspecies P. a. aegeria has a more orange background and the hindwing underside eyespots are reddish brown rather than black or dark gray. The two forms gradually intergrade into each other. Subspecies P. a. oblita is a darker brown, often approaching black with white rather than cream spots. The underside of its hindwings has a marginal pale purple band and a row of conspicuous white spots. The spots of subspecies P. a. insula are a tawny orange rather than a cream color. The underside of the forewings has patches of pale orange, and the underside of the hindwing has a purple-tinged band. Although there is considerable variation with each subspecies, identification of the different subspecies is manageable.

The morphology of this butterfly varies as a gradient down its geographic cline from north to south. The northern butterflies in this species have a bigger size, adult body mass, and wing area. These measurements decrease as one moves in a southerly direction in the speckled wood's range. Forewing length on the other hand increases moving in a northerly direction. This is due to the fact that in the cooler temperatures of the northern part of this butterfly's range, the butterflies need larger forewings for thermoregulation. Finally, the northern butterflies are darker than their southern counterpart, and there is a coloration gradient, down their geographical cline.

The speckled wood occupies a diversity of grassy, flowery habitats in forest, meadow steppe, woods, and glades. It can also be found in urban areas alongside hedges, in wooded urban parks, and occasionally in gardens. Within its range the speckled wood typically prefers damp areas. It is generally found in woodland areas throughout much of the Palearctic realm. P. a. tircis is found in northern and central Europe, Asia Minor, Syria, Russia, and central Asia, and the P. a. aegeria is found in southwestern Europe and North Africa. Two additional subspecies are found within the British Isles: the Scottish speckled wood (P. a. oblita) is restricted to Scotland and its surrounding isles, and the Isles of Scilly speckled wood (P. a. insula) is found only on the Isles of Scilly. P. a. tricis and P. a. aegeria gradually intergrade into each other.

29-9-2016 LAKELANDS, ESSEX - MUTE SWAN (Cygnus olor)

The Mute swan (Cygnus olor) is known as an integral feature of urban parks as well as most of the waterways in our regions. But originally this beautiful white bird was a wild animal, not always with compatible behavior and habits for life in city parks. It is also amongst the heaviest of the world's flying birds.

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.

29-9-2016 LAKELANDS, ESSEX - MALLARD HYBRID (FEMALE) (Anas platyrhynchos)

The mallard is considered to be a species of least concern by the International Union for Conservation of Nature (IUCN). 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 which may have supported more localised, sensitive species of waterfowl before development. The non-migratory mallard interbreeds with indigenous wild ducks of closely related species through genetic pollution by producing fertile offspring. Complete hybridisation of various species of wild duck gene pools could result in the extinction of many indigenous waterfowl. 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.

Mallards frequently interbreed with their closest relatives in the genus Anas, such as the American black duck, and also with species more distantly related, such as the northern pintail, leading to various hybrids that may be fully fertile. The mallard has hybridised with more than 40 species in the wild, and an additional 20 species in captivity, though fertile hybrids typically have two Anas parents. Mallards and their domestic conspecifics are fully interfertile; many wild mallard populations in North America contain significant amounts of domestic mallard DNA.

29-9-2016 LAKELANDS, ESSEX - GREYLAG GOOSE (Anser anser)

The Greylag goose (Anser anser) is a large goose in the waterfowl family Anatidae. Its distribution is widespread, with birds from the north of its range in Europe and Asia migrating southwards to spend the winter in warmer places. It is the ancestor of most breeds of domestic goose, having been domesticated at least as early as 1360 BC.

The Greylag is the largest and bulkiest of the grey geese of the genus Anser, but is more lightly built and agile than its domestic relative. It has a rotund, bulky body, a thick and long neck, and a large head and bill. It has pink legs and feet, and an orange or pink bill with a white or brown nail (hard horny material at the tip of the upper mandible). The plumage of the Greylag goose is greyish brown, with a darker head and paler breast and belly with a variable amount of black spotting. It has a pale grey forewing and rump which are noticeable when the bird is in flight or stretches its wings on the ground. It has a white line bordering its upper flanks, and its wing coverts are light-colored, contrasting with its darker flight feathers. Its plumage is patterned by the pale fringes of the feathers. Juveniles differ mostly in their lack of black speckling on the breast and belly and by their greyish legs. Adults have a distinctive 'concertina' pattern of folds in the feathers on their necks.

Greylag geese breed in Iceland, Norway, Sweden, Finland, the Baltic States, northern Russia, Poland, eastern Hungary, and Romania. They also breed locally in the United Kingdom, Denmark, Germany, Austria, the Czech Republic, Slovakia, and North Macedonia. The eastern race extends eastwards across a broad swathe of Asia to China. European birds migrate southwards to the Mediterranean region and North Africa. Asian birds migrate to Azerbaijan, Iran, Pakistan, northern India, Bangladesh, and eastward to China. In North America, there are both feral domestic geese, which are similar to greylags, and occasional vagrant greylags. 

Greylag geese seen in the wild in New Zealand probably originated from the escape of farmyard geese, same as in Australia, where feral birds are now established in the east and southeast of the country. Greylag geese breed on moors with scattered lochs, in marshes, fens, and peat-bogs, besides lakes and on little islands some way out to sea. They like the dense ground cover of reeds, rushes, heather, bushes, and willow thickets. On their wintering grounds, they frequent salt marshes, estuaries, freshwater marshes, steppes, flooded fields, bogs, and pastures near lakes, rivers, and streams. They also visit agricultural land where they feed on crops, moving at night to shoals and sand banks on the coast, mud banks in estuaries, or secluded lakes.

29-9-2016 LAKELANDS, ESSEX - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

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.

Great cormorants have large populations and are widespread, although surveys are not complete across their range. Being an important fish competitor, in the past, they were almost extinct in Europe. However, in recent years increases have been observed, thanks to intensive protection. But in some countries, expanding conflicts with fish farms and fisheries lead to new persecution. Another threat is that hatchlings may be eaten by raptors before fledging.

The IUCN Red List reports that the global population of Great cormorants is about 1,400,000-2,100,000 individuals. The European population is estimated at 401,000-512,000 pairs, which equates to 803,000-1,020,000 mature individuals. Overall, currently, Great cormorants are classified as Least Concern (LC) on the IUCN Red List and their numbers today are increasing.
