Grey heron

The grey heron (Ardea cinerea) is a long-legged predatory wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water or stalking its prey through the shallows.

Standing up to 1 m tall, adults weigh from 1 to 2 kg (2.2 to 4.4 lb). They have a white head and neck with a broad black stripe that extends from the eye to the black crest. The body and wings are grey above and the underparts are greyish-white, with some black on the flanks. The long, sharply pointed beak is pinkish-yellow and the legs are brown.

The birds breed colonially in spring in "heronries", usually building their nests high in trees. A clutch of usually three to five bluish-green eggs is laid. Both birds incubate the eggs for around 25 days, and then both feed the chicks, which fledge when 7-8 weeks old. Many juveniles do not survive their first winter, but if they do, they can expect to live for about 5 years.

In Ancient Egypt, the deity Bennu was depicted as a heron in New Kingdom artwork. In Ancient Rome, the heron was a bird of divination. Roast heron was once a specially prized dish; when George Neville became Archbishop of York in 1465, 400 herons were served to the guests.

Description

GreyHeron3 MJF
Head, with neck retracted

The grey heron is a large bird, standing up to 100 cm (39 in) tall and measuring 84–102 cm (33–40 in) long with a 155–195 cm (61–77 in) wingspan.[2] The body weight can range from 1.02–2.08 kg (2.2–4.6 lb).[3] The plumage is largely ashy-grey above, and greyish-white below with some black on the flanks. Adults have the head and neck white with a broad black supercilium that terminates in the slender, dangling crest, and bluish-black streaks on the front of the neck. The scapular feathers are elongated and the feathers at the base of the neck are also somewhat elongated. Immature birds lack the dark stripe on the head and are generally duller in appearance than adults, with a grey head and neck, and a small, dark grey crest. The pinkish-yellow beak is long, straight and powerful, and is brighter in colour in breeding adults. The iris is yellow and the legs are brown and very long.[4]

The main call is a loud croaking "fraaank", but a variety of guttural and raucous noises is heard at the breeding colony. The male uses an advertisement call to encourage a female to join him at the nest, and both sexes use various greeting calls after a pair bond has been established. A loud, harsh "schaah" is used by the male in driving other birds from the vicinity of the nest and a soft "gogogo" expresses anxiety, as when a predator is nearby or a human walks past the colony. The chicks utter loud chattering or ticking noises.[4]

Taxonomy and evolution

Herons are a fairly ancient lineage and first appeared in the fossil record in the Paleogene period; very few fossil herons have been found, though. By seven million years ago (the late Miocene), birds closely resembling modern forms and attributable to modern genera had appeared.[5]

Herons are members of the family Ardeidae, and the majority of extant species are in the subfamily Ardeinae and known as true or typical herons. This subfamily includes the herons and egrets, the green herons, the pond herons, the night herons, and a few other species. The grey heron belongs in this subfamily and is placed in the genus Ardea, which also includes the cattle egret and the great egret.[5] The grey heron was first described in 1758 by the Swedish naturalist Carl Linnaeus, who gave it the name Ardea cinerea. The scientific name comes from Latin ardea "heron", and cinerea , "ash-grey" (from cineris ashes).[6]

Four subspecies are recognised:[7]

It is closely related and similar to the North American great blue heron (Ardea herodias), which differs in being larger, and having chestnut-brown flanks and thighs, and to the cocoi heron (Ardea cocoi) from South America with which it forms a superspecies. Some authorities believe that the subspecies A. c. monicae should be considered a separate species.[8] It has been known to hybridise with the great egret (Ardea alba), the little egret (Egretta garzetta), the great blue heron and the purple heron (Ardea purpurea).[9] The Australian white-faced heron is often incorrectly called a grey heron.[10] In Ireland, the grey heron is often colloquially called a "crane".[11]

Distribution and habitat

The grey heron has an extensive range throughout most of the Palearctic ecozone. The range of the nominate subspecies A. c. cinerea extends to 70° N in Norway and 66°N in Sweden, but otherwise its northerly limit is around 60°N across the rest of Europe and Asia eastwards as far as the Ural Mountains. To the south, its range extends to northern Spain, France, central Italy, the Balkans, the Caucasus, Iraq, Iran, India, and Myanmar (Burma). It is also present in Africa south of the Sahara Desert, the Canary Islands, Morocco, Algeria, Tunisia, and many of the Mediterranean Islands. It is replaced by A. c. jouyi in eastern Siberia, Mongolia, eastern China, Hainan, Japan, and Taiwan. In Madagascar and the Aldabra Islands, the subspecies A. c. firasa is found, while the subspecies A. c. monicae is restricted to Mauritania and offshore islands.[4]

Over much of its range, the grey heron is resident, but birds from the more northerly parts of Europe migrate southwards, some remaining in Central and Southern Europe, others travelling on to Africa south of the Sahara Desert.[4]

Within its range, the grey heron can be found anywhere with suitable watery habitat that can supply its food. The water body needs to be either shallow enough, or have a shelving margin in it, which it can wade. Although most common in the lowlands, it also occurs in mountain tarns, lakes, reservoirs, large and small rivers, marshes, ponds, ditches, flooded areas, coastal lagoons, estuaries, and the sea shore. It sometimes forages away from water in pasture, and it has been recorded in desert areas, hunting for beetles and lizards. Breeding colonies are usually near feeding areas, but exceptionally may be up to 8 km (5 mi) away, and birds sometimes forage as much as 20 km (12 mi) from the nesting site.[4]

Behavior

The grey heron has a slow flight, with its long neck retracted (S-shaped). This is characteristic of herons and bitterns, and distinguishes them from storks, cranes, and spoonbills, which extend their necks.[4] It flies with slow wing-beats and sometimes glides for short distances. It sometimes soars, circling to considerable heights, but not as often as the stork. In spring, and occasionally in autumn, birds may soar high above the heronry and chase each other, undertake aerial manoeuvres or swoop down towards the ground. The birds often perch in trees, but spend much time on the ground, striding about or standing still for long periods with an upright stance, often on a single leg.[4]

Diet and feeding

Grey Heron, Leighton Moss
Swallowing an eel

Fish, amphibians, small mammals, and insects are taken in shallow water with the heron's long bill. It has also been observed catching and killing juvenile birds such as ducklings, and occasionally takes birds up to the size of a water rail.[12] It may stand motionless in the shallows, or on a rock or sandbank beside the water, waiting for prey to come within striking distance. Alternatively, it moves slowly and stealthily through the water with its body less upright than when at rest and its neck curved in an "S". It is able to straighten its neck and strike with its bill very fast.[4]

Small fish are swallowed head first, and larger prey and eels are carried to the shore where they are subdued by being beaten on the ground or stabbed by the bill. They are then swallowed, or have hunks of flesh torn off. For prey such as small mammals and birds or ducklings, the prey is held by the neck and either drowned, suffocated, or killed by having its neck snapped with the heron's beak, before being swallowed whole. The bird regurgitates pellets of indigestible material such as fur, bones and the chitinous remains of insects. The main periods of hunting are around dawn and dusk, but it is also active at other times of day. At night it roosts in trees or on cliffs, where it tends to be gregarious.[4]

This species breeds in colonies known as heronries, usually in high trees close to lakes, the seashore, or other wetlands. Other sites are sometimes chosen, and these include low trees and bushes, bramble patches, reed beds, heather clumps and cliff ledges. The same nest is used year after year until blown down; it starts as a small platform of sticks but expands into a bulky nest as more material is added in subsequent years. It may be lined with smaller twigs, strands of root or dead grasses, and in reed beds, it is built from dead reeds. The male usually collects the material, while the female constructs the nest. Breeding activities take place between February and June. When a bird arrives at the nest, a greeting ceremony occurs in which each partner raises and lowers its wings and plumes.[11] In continental Europe, and elsewhere, nesting colonies sometimes include nests of the purple heron and other heron species.[4]

Building nest

Courtship involves the male calling from his chosen nesting site. On the arrival of the female, both birds participate in a stretching ceremony, in which each bird extends its neck vertically before bringing it backwards and downwards with the bill remaining vertical, simultaneously flexing its legs, before returning to its normal stance. The snapping ceremony is another behaviour where the neck is extended forward, the head is lowered to the level of the feet, and the mandibles are vigorously snapped together. This may be repeated 20-40 times. When the pairing is settled, the birds may caress each other by attending to the other bird's plumage. The male may then offer the female a stick, which she incorporates into the nest. At this, the male becomes excited, further preening the female and copulation takes place.[4]

Eggs, collection Museum Wiesbaden

The clutch of eggs usually numbers three to five, though as few as two and as many as seven eggs have been recorded. The eggs have a matt surface and are greenish-blue, averaging 60 mm × 43 mm (2.36 in × 1.69 in). The eggs are normally laid at two-day intervals and incubation usually starts after the first or second egg has been laid. Both birds take part in incubation and the period lasts about 25 days. Both parents bring food for the young. At first, the chicks seize the adult's bill from the side and extract regurgitated food from it. Later, the adult disgorges the food at the nest and the chicks squabble for possession. They fledge at 7-8 weeks. Usually, a single brood is raised each year, but two broods have been recorded.[4]

The oldest recorded bird lived for 23 years, but the average life expectancy in the wild is about 5 years. Only about a third of juveniles survive into their second year, many falling victim to predation.[11]

City life

Grey herons have the ability to live in cities where habitats and nesting space are available. In the Netherlands, it has established itself over the past decades in great numbers in urban environments. In cities such as Amsterdam, they are ever present and well adapted to modern city life.[13] They hunt as usual, but also visit street markets and snackbars. Some individuals make use of people feeding them at their homes or share the catch of recreational fishermen. Similar behaviour on a smaller scale has been reported in Ireland.[14] Garden ponds stocked with ornamental fish are attractive to herons, and may provide young birds with a learning opportunity on how to catch easy prey.[15]

Herons have been observed visiting water enclosures in zoos, such as spaces for penguins, otters, pelicans, and seals, and taking food meant for the animals on display.[16][17][18][19]

Predators and parasites

Being large birds with powerful beaks, grey herons have few predators as adults, but the eggs and young are more vulnerable. The adult birds do not usually leave the nest unattended, but may be lured away by marauding crows or kites.[20] A dead grey heron found in the Pyrenees is thought to have been killed by an otter. The bird may have been weakened by harsh winter weather causing scarcity of its prey.[21]

A study suggested that Central European grey herons host 29 species of parasitic worms. The dominant species consisted of Apharyngostrigea cornu (67% prevalence), Posthodiplostomum cuticola (41% prevalence), Echinochasmus beleocephalus (39% prevalence), Uroproctepisthmium bursicola (36% prevalence), Neogryporhynchus cheilancristrotus (31% prevalence), Desmidocercella numidica (29% prevalence), and Bilharziella polonica (5% prevalence). Juvenile grey herons were shown to host fewer species, but the intensity of infection was higher in the juveniles than in the adult herons. Of the digenean flatworms found in Central European grey herons, 52% of the species likely infected their definitive hosts outside Central Europe itself, in the premigratory, migratory, or wintering quarters, despite the fact that a substantial proportion of grey herons does not migrate to the south.[22]

In human culture

"The Heron. Common Heron, Heronsewgh, or Heronshaw. (Ardea cinerea, Lath.—Héron cendré, Temm.)" wood engraving by Thomas Bewick in his History of British Birds, volume 2, 1804

In Ancient Egypt, the bird deity Bennu, associated with the sun, creation, and rebirth, was depicted as a heron in New Kingdom artwork.[23]

In Ancient Rome, the heron was a bird of divination that gave an augury (sign of a coming event) by its call, like the raven, stork, and owl.[24]

Roast heron was once a specially prized dish in Britain for special occasions such as state banquets. For the appointment of George Neville as Archbishop of York in 1465, 400 herons were served to the guests. Young birds were still being shot and eaten in Romney Marsh in 1896. Two grey herons feature in a stained-glass window of the church in Selborne, Hampshire.[25]

The English surnames Earnshaw, Hernshaw, Herne, and Heron all derive from the heron, the suffix -shaw meaning a wood, referring to a place where herons nested.[26]

Black-headed heron

The black-headed heron (Ardea melanocephala) is a wading bird of the heron family Ardeidae, common throughout much of sub-Saharan Africa and Madagascar. It is mainly resident, but some west African birds move further north in the rainy season.

This species usually breeds in the wet season in colonies in trees, reedbeds or cliffs. It builds a bulky stick nest, and lays 2–4 eggs.

It often feeds in shallow water, spearing fish or frogs with its long, sharp bill. It will also hunt well away from water, taking large insects, small mammals, and birds. It will wait motionless for its prey, or slowly stalk its victim.

The black-headed heron is a large bird, standing 85 cm tall, and it has a 150 cm wingspan. It is nearly as large as the grey heron, which it resembles in appearance, although it is generally darker. Its plumage is largely grey above, and paler grey below. It has a powerful dusky bill.

The flight is slow, with the neck retracted. This is characteristic of herons and bitterns, and distinguishes them from storks, cranes, and spoonbills, which extend their necks. The white underwing coverts are striking in flight.

The call is a loud croaking.

Halsnøya, Rogaland

Halsnøya (locally called Halsne) is an island in Finnøy municipality in Rogaland county, Norway. The 4.9-square-kilometre (1.9 sq mi) island is the largest island in of the Fisterøyene archipelago. Halsnøya is located south of the island of Ombo, southeast of the Sjernarøyane islands, east of the island of Finnøy, northeast of the island of Fogn, and west of the island of Randøy. The island is only accessible by boat, with regular ferry service from the nearby islands and to the mainland.

The island is hilly with some forest, where there are deer and pine marten. The bird life is rich, including a large grey heron colony. The rest of the island is cultivated for farming or pasture land. The 214-metre (702 ft) tall Eikefjellet mountain is the highest point on the island.

Heron

The herons are long-legged freshwater and coastal birds in the family Ardeidae, with 64 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera Botaurus and Ixobrychus are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus Zebrilus, form a monophyletic group within the Ardeidae. Egrets are not a biologically distinct group from the herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks.

The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, Ardea and Egretta. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered to constitute a separate monotypic family, the Cochlearidae or the boat-billed heron, is now regarded as a member of the Ardeidae.

Although herons resemble birds in some other families, such as the storks, ibises, spoonbills, and cranes, they differ from these in flying with their necks retracted, not outstretched. They are also one of the bird groups that have powder down. Some members of this group nest colonially in trees, while others, notably the bitterns, use reed beds.

Lake Koman

Lake Koman (Albanian: Liqeni i Komanit) is a reservoir on the Drin River in northern Albania. Lake Koman is surrounded by dense forested hills, vertical slopes, deep gorges, and a narrow valley, completely taken up by the river. Besides the Drin, it is fed by the Shala and Valbona Rivers. The lake stretches in an area of 34 km2 (13 sq mi), its width being 400 m (0.25 mi). The narrowest gorge, which is surrounded by vertical canyon walls, is more than 50 m (0.031 mi) wide. The reservoir was constructed between 1979 and 1988 near the village of Koman with a height of 115 m (377 ft).The combination of specific topography and hydrological conditions, have contributed to the formation of different habitats. The golden jackal, red fox, european badger, eurasian otter, beech marten, european polecat are the primary predatory mammals. A high number of bird species have been observed in the region, including the common kingfisher, common quail, grey heron, eurasian wryneck, great spotted woodpecker and black-headed gull.The Lake Koman Ferry operates daily on the lake from Koman to Fierza. The ferry connects the city of Bajram Curri to the region of Tropojë. The journey takes about two and a half hours and is also popular with the foreign tourists. Smaller boats bring people and goods to remote villages, which are often far away from the lake, but can only be reached by water.

Nelapattu Bird Sanctuary

Nelapattu Bird Sanctuary is a bird sanctuary in Nellore district, Andhra Pradesh, India, near the village of Nelapattu. It has an area of 458.92 hectares. It is an important breeding site for spot-billed pelicans (Pelecanus philippensis).Nelapattu has two major plant communities, Barringtonia swamp forests and southern dry evergreen scrub.

Southern dry evergreen scrub covers most of the sanctuary, including the 288 hectares of Kalluru Reserved Forest and 88 hectares of unreserved forest. The dominant tree and shrub species are Manilkara hexandra, Maba buxifolia, Memecylon edule, Buchanania angustifolia, Zizyphus xylopyrus, and others.The Barringtonia swamp forests are found in the 83-ha Nelapattu tank. The predominant tree species is Barringtonia acutangula (Hijal). This tree also grows in uplands, but the tree species found at Nelapattu can grow in flooded conditions lasting for 5 to 7 months. The saplings can survive total submersion during the long duration of flooding.About 189 bird species can be found at Nelapattu Bird Sanctuary, 50 of which are migratory. In addition to the spot-billed pelican, it is an important breeding site for white ibis, openbill stork, night heron, and little cormorant. Other migratory water birds that visit the sanctuary include pintail, common teal, dabchick, shoveler, coot, spot-bill duck, grey heron, darter, black-winged stilt, and garganey gadwall.

Parika Nature Reserve

Parika Nature Reserve (Estonian: Parika looduskaitseala) is a nature reserve in Viljandi County in southern Estonia.

The nature reserve is situated in and around Parika bog, and consists of a system of bogs and small lakes. It is an important habitat for several species of orchid, including coralroot orchid, common spotted orchid and common twayblade, but also other e.g. Nymphaea candida. The bird-life of the nature reserve is also rich; species commonly found here include the lesser spotted eagle, black stork and grey heron. Two trails for visitors have been prepared in the nature reserve.

Purple heron

The purple heron (Ardea purpurea) is a wide-ranging species of wading bird in the heron family, Ardeidae. The scientific name comes from Latin ardea "heron", and purpureus, "coloured purple". It breeds in Africa, central and southern Europe, and southern and eastern Asia. The Western Palearctic populations migrate between breeding and wintering habitats whereas the African and tropical-Asian populations are primarily sedentary, except for occasional dispersive movements.

It is similar in appearance to the more common grey heron but is slightly smaller, more slender and has darker plumage. It is also a more evasive bird, favouring densely vegetated habitats near water, particularly reed beds. It hunts for a range of prey including fish, rodents, frogs and insects, either stalking them or standing waiting in ambush.

Purple herons are colonial breeders and build a bulky nest out of dead reeds or sticks close to the water' edge among reeds or in dense vegetation. About five bluish-green eggs are laid and are incubated by both birds. The young hatch about four weeks later and fledge six weeks after that. The International Union for Conservation of Nature notes that the global population trend is downwards, largely because of the drainage of wetlands, but assesses the purple heron's conservation status as being of "least concern".

Rotten Calder

The Rotten Calder is a river to the east of East Kilbride, South Lanarkshire, Scotland and along with the Rotten Burn it forms the southern and western boundaries of Blantyre.

It begins as the Calder Water at its source at Ardochrig, and is joined by the Cleughearn, Lea and Drumloch Burns around Langlands Moss which drain from the Eldrig Hills. This river has also been titled the 'West' or 'South Calder Water', although the latter title is shared by another river in Motherwell. Upon being joined by the Rotten Burn to the south-east of East Kilbride, the river becomes the Rotten Calder Water. 'Water' is a term used in Scotland to denote a small river.

The Rotten Calder runs through a romantic scenic gorge titled Calderglen, where it flows through East Kilbride Parish. This area of the gorge is under the jurisdiction of Calderglen Country Park, run by South Lanarkshire Council. Over 160 nature trails border the river on both banks, in addition to the forest which occupies the slopes, and ferns, mosses and liverworts on the rocky precipices. Otter, roe deer and European green woodpecker can be seen in the southern reaches of the park. Buzzards can be seen hunting over open areas by the river and the grey heron, grey wagtail and dipper are common sights too. The river flows by the site of the former Calderwood Castle (demolished 1947-1951).

The gorge of the Rotten Calder Water was celebrated in books and poems for its romantic grandeur and lush ivy-tied crags. Many traces of 18th- and 19th-century landscape additions can be traced in the park, as well as old mines, quarries, and religious sites. After passing under the General's Bridge at Stoneymeadow, the Water flows by Crossbasket Castle (House) in an easterly direction, and on through the former estates of Greenhall and Milheugh where the valley is seen to give way to wide flood plains.

After Milheugh the river again regains its steep gorge and flows through scenery before flowing into the River Clyde near Bothwell Castle. There are many waterfalls on the river, these are Millwell Linn, Flatt Linn (Crutherland Linn), Torrance Linn (Fairy Linn or Walk Fort Linn), Black Linn, Trough Linn, Calderwood Linn (Castle Falls), Crossbasket Linn, Horseshoe Falls, Old Horseshoe Linn, Small Falls, and Milheugh Falls.

East Kilbride Angling Club have the fishing rights and stock the river with brown trout each year. Permits are available from Lightbody Quality Butchers of Murray Square, East Kilbride.

The river flows via the north side of Blantyre and forms the eastern boundary of the Newton district of Cambuslang before joining the River Clyde opposite Daldowie.

The valley of the Rotten Calder includes hermitages, islets, caves, crannies, ancient markings, fountains, fairy wells, numerous waterfalls, over 200 nature trails, summerhouses, ruined castles, and steep cliffs.

Spencer Road Wetlands

Spencer Road Wetlands is a one hectare Local Nature Reserve in Mitcham in the London Borough of Sutton. It is owned by Sutton Council and managed by the London Wildlife Trust.From about 1895 to 1959 the site was subject to controlled flooding for watercress production. It was left then unmanaged, and colonised by willow woodland, until the late 1980s, and in 1991 the London Wildlife Trust took over the management. The site has reed swamps with wetland vegetation, woodland, a sedge-bed and a pond. Insects include the twin-spotted wainscot and crescent moths, and there are birds such as grey heron, reed warbler and kingfisher.The entrance at the corner of Spencer Road and Wood Street is kept locked and there is no public access.

White-faced heron

The white-faced heron (Egretta novaehollandiae) also known as the white-fronted heron, and incorrectly as the grey heron, or blue crane, is a common bird throughout most of Australasia, including New Guinea, the islands of Torres Strait, Indonesia, New Zealand, and all but the driest areas of Australia.

It is a medium-sized heron, pale, slightly bluish-grey, with yellow legs and white facial markings. It can be found almost anywhere near shallow water, fresh or salt, and although it is prompt to depart the scene on long, slow-beating wings if disturbed, it will boldly raid suburban fish ponds.

Łuknajno Lake

Łuknajno [wukˈnajnɔ] (German: Lucknainer See) is a lake in the Masurian Lake District of north-eastern Poland, in Warmian-Masurian Voivodeship. It lies approximately 5 kilometres (3.1 mi) east of the town of Mikołajki, close to the north-western corner of Poland's largest lake called Śniardwy. Łuknajno covers an area of 6.8 square kilometres (2.6 sq mi), and has a maximum depth of 3 metres (9.8 ft).

The lake is the site of a nature reserve, and since 1977 has been designated a UNESCO Biosphere Reserve and a Ramsar site, in view of its importance as a breeding ground for water birds such as grebe, rail, moorhen, grey heron, bearded tit, white-tailed eagle, osprey, rust-coloured kite, cormorant and black tern. The lake is known since many decades as the habitat of the mute swan (Latin: Cygnus olor) – nesting there every year from a dozen to tens of dozen of pairs, and in time of moult arriving in numbers reaching up to 2,000 birds. The lake is part of the larger protected area known as Masurian Landscape Park.
