3-12-2015 SINGAPORE - YELLOW HOODED BLACKBIRD (MALE) (Chrysomus icterocephalus)

The yellow-hooded blackbird (Chrysomus icterocephalus) is a species of bird in the family Icteridae. It is found in grassy and brush areas near water in northern South America, and is generally fairly common. It is sexually dimorphic, and the genders resemble the respective genders of the larger yellow-headed blackbird of North America, though the male yellow-hooded blackbird lacks white in the wings.

In 2007, one was found in the Darien Lowlands of Panama. This was a rare vagrant, most likely from Colombia.

With a golden head, a white patch on black wings, and a call that sounds like a rusty farm gate opening, the Yellow-headed Blackbird demands your attention. Look for them in western and prairie wetlands, where they nest in reeds directly over the water. They’re just as impressive in winter, when huge flocks seem to roll across farm fields. Each bird gleans seeds from the ground, then leapfrogs over its flock mates to the front edge of the ever-advancing troupe.

The Yellow-headed Blackbird often nests in the same marsh as the Red-winged Blackbird. The larger Yellow-headed Blackbird is dominant to the Red-winged Blackbird, and displaces the smaller blackbird from the prime nesting spots. The Yellow-headed Blackbird is strongly aggressive toward Marsh Wrens too, probably because of the egg-destroying habits of the wrens. When the Yellow-headed Blackbird finishes breeding and leaves the marsh, Marsh Wrens expand into former blackbird territories.

The male Yellow-headed Blackbird defends a small territory of prime nesting reeds. He may attract up to eight females to nest within his area. The male helps feed nestlings, but usually only in the first nest established in his territory. The other females have to feed their young all by themselves.

In 1825, Charles Lucien Bonaparte, nephew of Napoleon Bonaparte, gave the first detailed description of the Yellow-headed Blackbird, which was collected in 1820 by Thomas Say and Sir John Richardson.

Because Yellow-headed Blackbirds always build their nests over the water, nestlings sometimes fall in and have to swim short distances to vegetation.

Pleistocene fossils of Yellow-headed Blackbirds (from 100,000 years ago) have been dug up in California, New Mexico, and Utah.

The Yellow-headed Blackbird’s scientific name, Xanthocephalus, means “yellow head.”

The oldest Yellow-headed Blackbird on record was at least 11 years, 8 months old. It was banded in Saskatchewan in 1983 and was found in Nebraska in 1995.

3-12-2015 JURONG, SINGAPORE - AUSTRALIAN PELICAN (Pelecanus conspicillatus)

The Australian pelican (Pelecanus conspicillatus) is a large waterbird in the family Pelecanidae, widespread on the inland and coastal waters of Australia and New Guinea, also in Fiji, parts of Indonesia and as a vagrant in New Zealand. It is a predominantly white bird with black wings and a pink bill. It has been recorded as having the longest bill of any living bird. It mainly eats fish, but will also consume birds and scavenge for scraps if the opportunity arises.

The Australian pelican was first described by Dutch naturalist Coenraad Jacob Temminck in 1824. Its specific epithet is derived from the Latin verb conspicere, meaning 'to behold', and refers to the 'spectacled' appearance created by its conspicuous eye markings.

The Australian pelican is medium-sized by pelican standards, with a wingspan of 2.3 to 2.6 m (7.5 to 8.5 ft). Weight can range from 4 to 13 kg (8.8 to 28.7 lb), although most of these pelicans weigh between 4.54 and 7.7 kg (10.0 and 17.0 lb). The average weight of four unsexed Australian pelicans was 5.5 kg (12 lb), making this the second heaviest Australian flying bird species on average, after the brolga, although the male of the more sexually dimorphic Australian bustard weighs a bit more at average and maximum weights (both birds are, of course, much smaller than the cassowary and emu). The pale, pinkish bill is enormous, even by pelican standards, and is the largest bill in the avian world. The record-sized bill was 50 cm (20 in) long. Females are slightly smaller with a notably smaller bill, which can measure as small as 34.6 cm (13.6 in) at maturity. The total length is boosted by the bill to 152–188 cm (60–74 in), which makes it rank alongside the Dalmatian pelican as the longest of pelicans.

Overall, the Australian pelican is predominantly white in colour. There is a white panel on the upper-wing and a white-V on the rump set against black along the primaries. During courtship, the orbital skin and distal quarter of the bill are orange-coloured with the pouch variously turning dark blue, pink and scarlet. The non-breeding adult has its bill and eye-ring a pale yellow and the pouch is a pale pinkish. Juvenile birds are similar to the adults, but with black replaced with brown and the white patch on upper wing reduced. Overall, their appearance is somewhat similar to several other pelicans, though the species is allopatric.

This species can occur in large expanses of mainland Australia and Tasmania. Australian pelicans occur primarily in large expanses of open water without dense aquatic vegetation. The habitats that can support them include large lakes, reservoirs, billabongs and rivers, as well as estuaries, swamps, temporarily flooded areas in arid zones, drainage channels in farmland, salt evaporation ponds and coastal lagoons. The surrounding environment is unimportant: it can be forest, grassland, desert, estuarine mudflats, an ornamental city park, or industrial wasteland, provided only that there is open water able to support a sufficient supply of food. However, they do seem to prefer areas where disturbance is relatively low while breeding. They may also roost on mudflats, sandbars, beaches, reefs, jetties and pilings.

The species became first known to occur in New Zealand from a specimen shot at Jerusalem in 1890 and small numbers of subfossil bones, the first found at Lake Grassmere in 1947, followed by records of other stray individuals. The bones were later described as a new (sub)species, Pelecanus (conspicillatus) novaezealandiae (Scarlett, 1966: "New Zealand pelican") as they appeared to be larger, but Worthy (1998), reviewing new material, determined that they were not separable from the Australian population. These fossils were first found in 1930.

Australian pelicans follow no particular schedule of regular movement, simply following the availability of food supplies. Drought frequently precedes movements. When the normally barren Lake Eyre filled during 1974 to 1976, for example, only a handful of pelicans remained around the coastal cities: when the great inland lakes dried again, the population dispersed once more, flocks of thousands being seen on the northern coasts. On some occasions, they are simply blown by the wind to new locations. It is a fairly regular visitor to the southern coast of New Guinea, as well as the Bismarck Islands and Solomon Islands. It occurs as a vagrant to Christmas Island, Vanuatu, Fiji, Palau and New Zealand. A population irruption occurred in 1978 into Indonesia, with Australian pelicans reaching Sulawesi, Java and possibly also Sumatra.

Australian pelicans feed by plunge-diving while swimming on the surface of the water. They work in groups to drive fish to shallower water, where they stick their sensitive bills in to snatch their prey. Some feeding grounds in large bodies of water have included up to 1,900 individual birds. They will sometimes also forage solitarily. Their predominant prey is fish and they commonly feed on introduced species such as goldfish, European carp and European perch. When possible, they also eat native fish, with a seeming preference for the perch Leiopotherapon unicolor. However, the Australian pelican seems to be less of a piscivore and more catholic in taste than other pelicans. It regularly feeds on insects and many aquatic crustaceans, especially the common yabby, prawns and the shrimps in the genus Macrobrachium. This pelican also takes other birds with some frequency, such as silver gulls, Australian white ibis and grey teal, including eggs, nestlings, fledglings and adults, which they may kill by pinning them underwater and drowning them. Reptiles, amphibians and small mammals are also taken when available. Reportedly even small dogs have been swallowed. The Australian pelican is an occasional kleptoparasite of other water birds, such as cormorants. Cannibalism of young pelicans has also been reported.

4-3-2016 OLIVA MARSHES, VALENCIA - BLACK REDSTART (FEMALE) (Phoenicurus ochruros)

The Black redstart (Phoenicurus ochruros) is a small passerine bird in the genus Phoenicurus. Like its relatives, it was formerly classed as a member of the thrush family (Turdidae), but is now known to be an Old World flycatcher (Muscicapidae).

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.

4-3-2016 CANAL LES FONTS OLIVA, VALENCIA - MUSKOVY DUCK (Cairina moschata)

The Muscovy duck (Cairina moschata) is a large duck native to the Americas. Although it is a tropical bird, it adapts well to cooler climates, thriving in weather as cold as −12 °C (10 °F) and able to survive even colder conditions.

Muscovy ducks are large birds. They are predominantly black and white, with the back feathers being iridescent and glossy in males, while the females are more drab. The amount of white on the neck and head is variable, as well as the bill, which can be yellow, pink, black, or any mixture of these. They may have white patches or bars on the wings, which become more noticeable during flight. Both, the males and the females of this species have pink or red wattles around the bill, those of the male being larger and more brightly colored.

Muscovy ducks are found in Mexico and Central and South America. Small wild and feral breeding populations occur in the United States, particularly in Florida, Louisiana, Massachusetts, and the lower Rio Grande Valley of Texas as well as in many other parts of North America, including southern Canada. Feral Muscovy ducks are also found in New Zealand, Australia, and parts of Europe. These birds usually inhabit wet forests, forested swamps, wetlands, lakes, rivers, streams, and nearby grassland and farm crops.

Muscovy ducks are agile and speedy birds. They are non-migratory and are active during the day; at night birds often roost in trees. Days are spent feeding by grazing on the ground or dabbling in shallow water. Muscovy ducks are social birds; they are often seen in pairs or small groups. They are aggressive ducks; males often fight over food, territory, or mates. The females fight with each other less often. Some adults will even peck at the ducklings if they are eating at the same food source. In order to communicate with each other, Muscovy ducks wag their tails, raise and lower their heads and use various vocalizations including hisses and quacks. Males have a low breathy call, and females produce a quiet trilling coo.

4-3-2016 OLIVA MARSHES, VALENCIA - EUROPEAN MOORHEN (Gallinula chloropus)

The Common moorhen (Gallinula chloropus) is a bird species in the rail family (Rallidae) found across many parts of the Old World. These birds live around well-vegetated marshes, ponds, canals, and other wetlands. The word 'moor' as a part of their name is an old sense meaning marsh.

Common moorhens have predominantly black and brown plumage, with the exception of a white under-tail, white streaks on the flanks, yellow legs, and a red frontal shield. The bill is red with a yellow tip. The young are browner and lack the red shield. The frontal shield of the adult has a rounded top and fairly parallel sides; the tailward margin of the red unfeathered area is a smooth waving line.

Сommon moorhens are widespread across Europe, Asia, and Africa. Populations in areas where the waters freeze, such as eastern Europe, will migrate to more temperate climates. In China, Common moorhens are largely resident south of the Yangtze River, whilst northern populations migrate in the winter. These birds live around well-vegetated marshes, ponds, canals, and other wetlands. They can even be found in city parks and urban areas.

Сommon moorhens are diurnal birds that spend their time swimming or walking along the shore. They forage beside or in the water, sometimes walking on lilypads or upending in the water to feed. They are often secretive but can become tame in some areas. Outside of the breeding season, Common moorhens prefer to spend their time alone; however, during the winter they may gather in groups to feed on sheltered lakes and ponds. To communicate with each other, these birds will give a wide range of gargling calls and will emit loud hisses when threatened.

Сommon moorhens have an omnivorous diet. They feed on a wide variety of vegetable material, seeds, and small aquatic creatures. The birds will also consume small fish, algae, insects, tadpoles, grass, berries, worms, and even snails.

Сommon moorhens are monogamous and territorial. They form pair-bonds that may last for several years. Pairs nest solitarily usually on top of thick mats of aquatic plants but may also nest in trees, shrubs, or on the ground in dense vegetation. Their nest is a wide shallow cup made with dead vegetation and lined with grass and leaves. Laying starts in spring, between mid-March and mid-May in Northern Hemisphere temperate regions. About 8 eggs are usually laid per female early in the season. Incubation lasts about three weeks. The chicks are precocial; they are hatched with eyes open and are covered in blackish down. Both parents incubate and feed the young. They fledge after 40-50 days, become independent usually a few weeks thereafter, and may raise their first brood the next spring.

Сommon moorhens are widespread across their wide range. However, in some areas populations of this species suffer from severe weather, habitat loss, pollution, and hunting. These birds are also sensitive to avian influenza disease and avian botulism which outbreaks can be a threat in the future.

It’s been discovered that their apparent nervous tic, the constant flirting of the tail, is exactly that: a nervous tic. But it has a purpose. The flicking reveals the bird’s white bottom, and this is a signal to a predator that the individual is awake and vigilant and therefore primed to flee from any planned attack. The closer the moorhen is to danger, or the more exposed it feels, the more rapidly it flicks.

The orange-red bill with a bright yellow tip is actually coded so other moorhens can tell how healthy an individual is - much as flamingos do. Scientists have shown the different colours on the bird’s bill are actually health indicators. The red seems to be related to low levels of bacterial infection, and the yellow to blood parameters such as resistance to infection. The brighter the colours, the more attractive the bird is deemed.

4-3-2016 CANAL LES FONTS OLIVA, VALENCIA - MALLARD (MALE & FEMALE) (Anas platyrhynchos)

The mallard is widely distributed across the Northern and Southern Hemispheres; in North America its range extends from southern and central Alaska to Mexico, the Hawaiian Islands, across the Palearctic, from Iceland and southern Greenland and parts of Morocco (North Africa) in the west, Scandinavia and Britain to the north, and to Siberia, Japan, and South Korea. Also in the east, it ranges to south-eastern and south-western Australia and New Zealand in the Southern hemisphere It is strongly migratory in the northern parts of its breeding range, and winters farther south.

The mallard inhabits a wide range of habitats and climates, from the Arctic tundra to subtropical regions. It is found in both fresh- and salt-water wetlands, including parks, small ponds, rivers, lakes and estuaries, as well as shallow inlets and open sea within sight of the coastline. Water depths of less than 0.9 metres (3.0 ft) are preferred, with birds avoiding areas more than a few metres deep. They are attracted to bodies of water with aquatic vegetation.

4-3-2016 OLIVA KIKOPORT, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)

You can find House Sparrows most places where there are houses (or other buildings), and few places where there aren’t. Along with two other introduced species, the European Starling and the Rock Pigeon, these are some of our most common birds. Their constant presence outside our doors makes them easy to overlook, and their tendency to displace native birds from nest boxes causes some people to resent them. But House Sparrows, with their capacity to live so intimately with us, are just beneficiaries of our own success.

Sparrows usually fly at the speed of 24 miles per hour. When needed (in the case of danger), they can accelerate to the speed of 31 miles per hour. Sparrow is a symbol of loyalty in Japan owing to its friendly nature and ability to live in groups. Sparrows can survive between 4 and 5 years in the wild.

Once one of Britain’s commonest birds, numbers have crashed in recent years. London lost three-quarters of its sparrows between 1994 and 2000.

In some urban areas the population has fallen by 99%.

The cause of the sudden decline remains a mystery, though many improbable theories have been put forward, ranging from unleaded petrol to the use of mobile phones.

When sparrows were at their most numerous a century ago, there were many sparrow clubs whose members competed to kill the most birds in a year.

Though a long-established resident of Britain, it’s not thought to be a native, but spread naturally north from North Africa.

Man has always had a love-hate relationship with the cheeky sparrow. They have been introduced successfully to numerous countries around the world, including both North and South America, East and South Africa, Australia and New Zealand.

4-3-2016 CAMI LES FONTS OLIVA, ALICANTE - LITTLE EGRET (Egretta garzetta)

The Little egret (Egretta garzetta) is small elegant heron in the family Ardeidae. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. At one time common in Western Europe, the Little heron was hunted extensively in the 19th century to provide plumes for the decoration of hats and became locally extinct in Northwestern Europe and scarce in the south. Around 1950, conservation laws were introduced in southern Europe to protect the species and their numbers began to increase.

Little egrets are sociable birds and are often seen in small flocks. They are diurnal birds and feed mainly in the early morning and in the late afternoon. They use a variety of methods to procure their food; they stalk their prey in shallow water, often running with raised wings or shuffling their feet to disturb small fish, or may stand still and wait to ambush prey. Little egrets also make use of opportunities provided by cormorants disturbing fish or humans attracting fish by throwing bread into the water. On land, they walk or run while chasing their prey, feed on creatures disturbed by grazing livestock and ticks on the livestock, and even scavenge occasionally. Little egrets are silent birds in general, however, at their breeding colonies, they make various croaking and bubbling calls. When disturbed, they produce a harsh alarm call.

3-1-2015 JURONG, SINGAPORE - NICOBAR PIGEON (JUVENILE) (Caloenas nicobarica)

The Nicobar pigeon or Nicobar dove (Caloenas nicobarica, Car: ma-kūö-kö) is a bird found on small islands and in coastal regions from the Andaman and Nicobar Islands, India, east through the Indonesian Archipelago, to the Solomons and Palau. It is the only living member of the genus Caloenas alongside the extinct spotted green pigeon and Kanaka pigeon, and is the closest living relative of the extinct dodo and Rodrigues solitaire.

1-12-2015 SIEM REAP, CAMBODIA - ASIAN COMMON TOAD (Duttaphrynus melanostictus)

Duttaphrynus melanostictus is commonly called Asian common toad, Asian black-spined toad, Asian toad, black-spectacled toad, common Sunda toad, and Javanese toad. It is probably a complex of more than one true toad species that is widely distributed in South and Southeast Asia.

The species grows to about 20 cm (8 in) long. Asian common toads breed during the monsoon, and their tadpoles are black. Young toads may be seen in large numbers after monsoon rains finish.

The wart patterns of the toads are unique and have been used for individual identification in studies.

The top of the head has several bony ridges, along the edge of the snout (canthal ridge), in front of the eye (preorbital), above the eye (supraorbital), behind the eye (postorbital), and a short one between the eye and ear (orbitotympanic). The snout is short and blunt, and the space between the eyes is broader than the upper eyelid width. The ear drum or tympanum is very distinct and is at least as wide as two-thirds the diameter of the eye. The first finger is often longer than the second and the toes are at least half webbed. A warty tubercle is found just before the junction of the thigh and shank (subarticular tubercle) and two moderate ones are on the shank (metatarsus). No skin fold occurs along the tarsus. The “knee” (tarsometatarsal articulation) reaches the tympanum or the eye when the hind leg is held parallel along the side of the body. The dorsal side is covered with spiny warts. The parotoids are prominent, kidney-shaped, or elliptical and elongated, and secrete milky white Bufotoxin. The dorsal side is yellowish or brownish and the spines and ridges are black. The underside is unmarked or spotted. Males have a subgular vocal sac and black pads on the inner fingers that help in holding the female during copulation.

Asian common toads breed in still and slow-flowing rivers and temporary and permanent ponds and pools. Adults are terrestrial and may be found under ground cover such as rocks, leaf litter, and logs, and are also associated with human habitations. The larvae are found in still and slow-moving waterbodies. They are often seen at night under street lamps, especially when winged termites swarm. They have been noted to feed on a wide range of invertebrates, including scorpions. Tadpoles grown in sibling groups metamorphosed faster than those that were kept in mixed groups. Tadpoles have been shown to be able to recognize kin. The 96h LC50 of commercial grade malathion for the tadpoles is 7.5 mg/L and sublethal levels of exposure can impair swimming.

1-12-2015 ANGKOR WAT, CAMBODIA - SIGNATURE SPIDER (Complex Argiope anasuja)

Argiope anasuja, is a species of harmless orb-weaver spider (family Araneidae) found from the Seychelles to India, Pakistan and Sri Lanka, in the Maldives and in the Brazil.

Female is about 8-12 mm long and male is 3.5-4.5 mm. After Cephalothorax greyish brown with hairs. Sternum heart shaped with hairy pubescent white patch. Palps bear spines. Legs greyish brown and hairy. Femora dorsally yellowish. Abdomen pentagonal and hairy. Dorsum yellowish with brown transverse bands. Three sigilla pairs distinct. Ventrum dark brownish with two longitudinal white patches.

29-1-2015 JALON, ALICANTE - LARGE TORTOISESHELL BUTTERFLY (Nymphalis polychloros)

The Large Tortoiseshell was once widespread across Britain and most common in the woodlands of central and southern England but while its numbers were always known to fluctuate, it declined to extinction by the 1960s. This butterfly has not been recorded from Ireland.

It is still common in some parts of Europe, but declining in others. There continue to be sporadic records in Britain, the majority from the south coast but some are considered to be of specimens released from reared stock rather than genuine immigrants.

There have been several suggested causes for its decline - including climate change, parasitism, and the effect of Dutch Elm disease on one of its primary foodplants.

3-12-2015 JURONG, SINGAPORE - WHITE BREASTED CORMORANT (Phalacrocorax carbo ssp. Lucidus)

The white-breasted cormorant (Phalacrocorax lucidus) is much like the widespread great cormorant and if not a regional variant of the same species, is at least very closely related. It is distinguished from other forms of the great cormorant by its white breast and by the fact that subpopulations are freshwater birds. Phalacrocorax lucidus is not to be confused with the smaller and very different endemic South Australian black-faced cormorant, which also is sometimes called the white-breasted cormorant.

3-2-2016 VILLALONGA RESERVOIR, VALENCIA - COMMON KINGFISHER (MALE) (Alcedo atthis)

The common kingfisher (Alcedo atthis), also known as the Eurasian kingfisher and river kingfisher, is a small kingfisher with seven subspecies recognized within its wide distribution across Eurasia and North Africa. It is resident in much of its range, but migrates from areas where rivers freeze in winter.

This sparrow-sized bird has the typical short-tailed, large-headed kingfisher profile; it has blue upperparts, orange underparts and a long bill. It feeds mainly on fish, caught by diving, and has special visual adaptations to enable it to see prey under water. The glossy white eggs are laid in a nest at the end of a burrow in a riverbank.

The common kingfisher was first described by Carl Linnaeus in the 10th edition of his Systema Naturae in 1758 as Gracula atthis. The modern binomial name derives from the Latin alcedo, 'kingfisher' (from Greek ἀλκυών, halcyon), and Atthis, a beautiful young woman of Lesbos, and favourite of Sappho.

The genus Alcedo comprises seven small kingfishers that all eat fish as part of their diet. The common kingfisher's closest relative is the cerulean kingfisher that has white underparts and is found in parts of Indonesia. 

The Common kingfisher (Alcedo atthis) is a small kingfisher widely distributed across Eurasia and North Africa. It is amongst the most colorful birds but despite its extraordinary colors, sometimes the Common kingfisher is difficult to see when it is in a dappled shade, and its colors are also not very obvious in flight. Furthermore, due to its shy nature, the Common kingfisher often remains hidden from a human's eye.

The Common kingfisher has the typical short-tailed, dumpy-bodied, large-headed, and long-billed shape. The adult male of the western European subspecies, A. a. ispida has green-blue upperparts with pale azure-blue back and rump, a rufous patch by the bill base, and a rufous ear patch. It has a green-blue neck stripe, white neck blaze and throat, rufous underparts, and a black bill with some red at the base. The legs and feet are bright red. The female is identical in appearance to the male except that her lower mandible is orange-red with a black tip. The juvenile is similar to the adult but with duller and greener upperparts and paler underparts. Its bill is black, and the legs are also initially black. Feathers are moulted gradually between July and November with the main flight feathers taking 90-100 days to moult and regrow. Some that moult late may suspend their moult during cold winter weather.

3-2-2016 VILLALONGA RESERVOIR, VALENCIA - GREY WAGTAIL (Motacilla cinerea)

The breeding season is April to July and the nest is placed near fast running streams or rivers on an embankment between stones and roots. The male in display, makes short flights up into the air and descends slowly with fluttering flight accompanied by a rapid series of chipping high notes. In Europe the nests are often made in holes in manmade structures. The clutch consists of 3–6 speckled eggs and multiple broods may be raised with declining numbers in the clutch in subsequent broods. The usual clutch size is five in Ireland and the breeding success is about 80% with predation of eggs or chicks being the main cause of breeding failure. The Canary Islands population typically have smaller clutches and the breeding season is not as short and well marked as in populations at higher latitudes. The incubation period is about two weeks with chicks fledging within a fortnight. They live for a maximum of 8 years in the wild.

These birds feed on a variety of aquatic invertebrates including adult flies, mayflies, beetles, crustacea and molluscs. They often forage along roadsides in winter, flushing with a sharp chi-cheep call and flying up further along the road but after some distance turning back to return to the original location.

In winter, they roost in small groups. Wintering birds have been known to return to the same sites, sometimes a small urban garden, each year.

Adults often have parasitic ticks, Ixodes ricinus, which can harbour Borrelia and thus can potentially disperse Lyme disease over a wide region. Coccidia such as Isospora sp. are known in this species. The common cuckoo is sometimes a brood parasite of this species, and kestrels may sometimes prey on them.
