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.

29-9-2016 LAKELANDS, ESSEX - EURASIAN COOT (Fulica atra)

The Eurasian coot is 36–38 cm (14–15 in) in length with a wing-span of 70–80 cm (28–31 in); males weigh around 890 g (31 oz) and females 750 g (26 oz). It is largely black except for the white bill and frontal shield (which gives rise to the phrase "as bald as a coot", in use as early as 1430). As a swimming species, the coot has partial webbing on its long strong toes. The sexes are similar in appearance.

The juvenile is paler than the adult, has a whitish breast, and lacks the facial shield; the adult black plumage develops when about 3–4 months old, but the white shield is only fully developed at about one year old.

The Eurasian coot (Fulica atra), also known as the Common coot, or Australian coot, is a member of the rail and crake bird family, the Rallidae. It is found in Europe, Asia, Australia, New Zealand, and parts of North Africa. Similar-looking coot species are found throughout the world, with the largest variety of coot species living in South America.

Eurasian coots breed in Europe, Asia, Australia, and Africa. They have recently expanded their range into New Zealand. These birds are residents in the milder parts of their range only performing nomadic movements; however, populations from much of Asia migrate further south and west in winter as the waters freeze. Eurasian coots inhabit freshwater lakes, ponds, pools, creeks, rivers and river deltas, marshes, freshwater meadows, flooded grasslands, and freshwater, and saline lagoons.

Eurasian coots are much less secretive than most of the rail family, and frequently swim on open water or walk across waterside grasslands. They are quite aggressive birds, and strongly territorial during the breeding season, and both parents defend their nesting site. During the non-breeding season, they may form large flocks, possibly related to predator avoidance. Eurasian coots are reluctant to fly and when taking off run across the water surface with much splashing. They do the same, but without actually flying, when traveling a short distance at speed in territorial disputes or on land to escape from intruders. As with many rails, their weak flight does not inspire confidence, but on migration, usually at night, they can cover surprisingly large distances. When swimming they bob their heads, and make short dives from a little jump. When fighting other waterbirds (especially other coots), Eurasian coots attack by charging their opponent and striking them with their long legs. When feeding, these birds graze on land or in the water. In the water, they may upend in the fashion of a mallard or dive in search of food. Eurasian coots are noisy and have a wide repertoire of crackling, explosive, or trumpeting calls, often given at night.

29-9-2016 LAKELANDS, ESSEX - CANADA GOOSE (Branta canadensis)

The Canada goose (Branta canadensis) is a large wild goose native to the arctic and temperate regions of North America. Like most geese, the Canada goose is primarily herbivorous and normally migratory; often found on or close to fresh water. These birds are extremely adept at living in human-altered areas and have established breeding colonies in urban and cultivated habitats, which provide food and few natural predators. The success of this common park species has led to its often being considered a pest species because of its excrement, its depredation of crops, its noise, its aggressive territorial behavior toward both humans and other animals, and its habit of stalking and begging for food, the latter a result of humans disobeying artificial feeding policies toward wild animals.

Canada geese have a white mark on their beak, near their chin. Another distinctive feature of these birds is a white U-like band on their rump. The male of a breeding pair is usually bigger. The feet, legs, and beak of Canada geese are black. They have a blackish-brown tail and blackish rump. The back and scapulars are darker brown. The breast, abdomen, and flanks vary from light gray to dark chocolate brown in color, either being mixed with a black neck or separated from it by a white ring.

The Canada goose is a native North American species, being also introduced to the UK, New Zealand, Chile, Argentina, and the Falkland Islands. These animals can be found at different elevations from alpine to coastal regions. The habitat of Canada geese is open areas with short grass. As a general rule, these animals avoid areas with obstructions such as tall grass, to be able to watch for predators. They live near water bodies such as coastlines, rivers, marshes, or ponds. They can also be frequently found in agricultural or urban areas. They breed in Canada and the northern United States while their migration reaches as far as northern Europe.

They are diurnal, being active during the day. The geese spend a lot of time grazing and foraging. Canada geese forage for food on land as well as in the water. The geese are very social animals, forming large nesting colonies meanwhile making the nests at a certain distance from each other. Pair of nesting geese can either choose to live solitary or to use the same breeding area as other pairs do. During the breeding season, Canada geese form long-term pairs. During this period, males aggressively defend the nesting site and the goslings, not allowing humans and other animals to approach it. In the autumn, these birds congregate into large flocks, consisting of family groups, to migrate southward to their wintering grounds

Canada geese are monogamous, mating once in a lifetime, usually during the second year of their lives. Normally, the breeding season takes place in April-May, sometimes extending into June in areas with a colder climate. When the nesting site is chosen, the female builds the nest and lays 4-7 eggs whereas the male stands guard. Then the female incubates the eggs for about 28 days. As soon as hatched out, the chicks are able to feed, walk, swim and dive. They leave the nest in 1-2 days but stay with their parents for the first year of their lives. The parents help the young to find food, leading the chicks to feeding areas. Depending on the subspecies, chicks of Canada goose are able to fly within 7-9 weeks after hatching out.

29-9-2016 MALDON, ESSEX - TUFTED DUCK (FEMALE) (Aythya fuligula)

The Tufted duck (Aythya fuligula) is a small diving duck found in northern Eurasia. Its scientific name comes from Ancient Greek word aithuia, an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin words fuligo "soot" and gula "throat".

Adult males of this species are all black in color except for white flanks and a blue-grey bill with gold-yellow eyes, along with a thin crest on the back of their heads. They have an obvious head tuft that gives these birds their name. Adult females are brown with paler flanks and are more easily confused with other diving ducks. In flight Tufted ducks show a white stripe across the back of the wing.

Tufted ducks breed throughout temperate and northern Eurasia. They occasionally can be found as a winter visitor along both coasts of the United States and Canada. These ducks are migratory in most of their range and overwinter in the milder south and west of Europe, Africa, Middle-East, Southern Asia and all year in most of the United Kingdom. Tufted ducks breed close to marshes and lakes with plenty of vegetation to conceal the nest. They are also found on coastal lagoons, shorelines, estuaries, sheltered ponds, slow-flowing rivers, tidal bays or freshwater wetlands.

Tufted ducks are social birds and often form large flocks on open water in winter. They are highly aquatic and spend most of their life in the water. These birds feed mainly by diving, but they will sometimes upend from the surface. They are generally active during the day but migrate by night. Tufted ducks communicate with each other vocally. The females' call is a harsh, growling "karr", mostly given in flight. The males are mostly silent but they make whistles during courtship based on a simple "wit-oo".

Tufted ducks are serially monogamous; pairs form during migration and stay together for one breeding season. The breeding season occurs from May to early August. Tufted ducks nest singly or in loose groups usually near water and among dense vegetation. Females build the nest on the ground and line it with down and vegetation. They then lay 8 to 10 olive-grey eggs and incubate them alone around 26-28 days. During this time males leave to form moulting flocks. Ducklings hatch fully developed and are able to follow their mother to learn how to feed soon after hatching. They fledge 49 to 56 days after hatching and become independent after another 21 to 56 days. Young Tufted ducks reach reproductive maturity and able to breed for the first time when they are 1 year old.

The biggest threat to Tufted ducks is habitat loss due to the destruction of wetlands for human development, drainage, pollution and oil spills. They also suffer from disturbance on inland water bodies and noises from urban development, hunting, and predation.Tufted ducks feed on many aquatic invertebrates, thus controlling their populations. In turn, these birds serve an important food source for local predators.

29-9-2016 NORTHWOOD PARK, BASILDON - EUROPEAN ROBIN (Erithacus rubecula)

The European robin (Erithacus rubecula), known simply as the robin or robin redbreast in Great Britain and Ireland, is a small insectivorous passerine bird that belongs to the chat subfamily of the Old World flycatcher family. It is found across Europe, east to Western Siberia and south to North Africa; it is sedentary in most of its range except the far north.

It is about 12.5–14.0 cm (4.9–5.5 in) in length; the male and female are similar in colouration, with an orange breast and face lined with grey, brown upper-parts and a whitish belly.

The robin occurs in Eurasia east to Western Siberia, south to Algeria and on the Atlantic islands as far west as the Central Group of the Azores and Madeira. It is a vagrant in Iceland. In the southeast, it reaches Iran the Caucasus range. Irish and British robins are largely resident but a small minority, usually female, migrate to southern Europe during winter, a few as far as Spain. Scandinavian and Russian robins migrate to Britain and western Europe to escape the harsher winters. These migrants can be recognised by the greyer tone of the upper parts of their bodies and duller orange breast. The continental European robins that migrate during winter prefer spruce woods in northern Europe, contrasting with its preference for parks and gardens in Great Britain.

In southern Iberia, habitat segregation of resident and migrant robins occurs, with resident robins remaining in the same woodlands where they bred.

In the 15th century, when it became popular to give human names to familiar species, the bird came to be known as robin redbreast, which was eventually shortened to robin. As a given name, Robin is originally a smaller form of the name Robert. The term robin is also applied to some birds in other families with red or orange breasts. These include the American robin (Turdus migratorius, a thrush) and the Australasian robins of the family Petroicidae, the relationships of which are unclear.

Other older English names for the bird include ruddock and robinet. In American literature of the late 19th century, this robin was frequently called the English robin.

Attempts to introduce the European robin into Australia and New Zealand in the latter part of the 19th century were unsuccessful. Birds were released around Melbourne, Auckland, Christchurch, Wellington and Dunedin by various local acclimatisation societies, with none becoming established. There was a similar outcome in North America, as birds failed to become established after being released in Long Island, New York in 1852, Oregon in 1889–1892, and the Saanich Peninsula in British Columbia in 1908–1910.
