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. 

3-2-2016 VILLALONGA RESERVOIR, VALENCIA - GREEN SANDPIPER (Tringa ochropus)




3-12-2015 JURONG, SINGAPORE - VIOLET BACKED STARLING (MALE) (Cinnyricinclus leucogaster)


The violet-backed starling (Cinnyricinclus leucogaster), also known as the plum-coloured starling or amethyst starling, is a relatively small species (17 cm) of starling in the family Sturnidae. It is the only member of the genus Cinnyricinclus. This strongly sexually dimorphic species is found widely in the woodlands and savannah forest edges of mainland sub-Saharan Africa. It is rarely seen on the ground, but instead found in trees and other locations away from the ground.


The violet-backed starling is a sexually dimorphic species with adults reaching a length of about 18 cm (7 in). The male has an iridescent violet head and back and pure white underparts. The female has a thrush-like appearance with brown, boldly-streaked upper parts and white, heavily-streaked underparts. Both sexes have yellow irises and black bills and legs.

The violet-backed starling is a common bird in Sub-Saharan Africa, occurring in most locations with the exception of the dense rainforest of the Congo Basin, and the more arid parts of southwestern Africa. It is found in open woodland, gallery forests, forest verges and clearings. In the Chyulu Hills of Kenya, it occurs at altitudes up to 2,100 m (6,900 ft).


The diet of the violet-backed starling includes fruits, seeds and arthropods. It sometimes hawks for insects in a manner similar to flycatchers. It largely feeds in the canopy, seldom foraging on the ground. The nest is usually located in a crevice in a tree within a few metres of the ground. Nesting material includes green leaves and dung. The female will incubate the clutch of two to four eggs, which are pale blue with reddish/brown spots, for 12–14 days. The male will help feed chicks until they fledge after about 21 days.

3-12-2015 JURONG, SINGAPORE - SACRED IBIS (Threskiornis aethiopicus)


The African sacred ibis (Threskiornis aethiopicus) is a species of ibis, a wading bird of the family Threskiornithidae. It is native to much of Africa, as well as small parts of Iraq, Iran and Kuwait. It is especially known for its role in Ancient Egyptian religion, where it was linked to the god Thoth. The species is currently extirpated from Egypt.

Wingspan is 112 to 124 cm (44 to 49 in) and body weight 1.35 to 1.5 kg (3.0 to 3.3 lb). Males are generally slightly larger than females.

The bald head and neck, thick curved bill and legs are black. The white wings show a black rear border in flight. The eyes are brown with a dark red orbital ring. Sexes are similar, but juveniles have dirty white plumage, a smaller bill and some feathering on the neck, greenish-brown scapulars and more black on the primary coverts.

This bird is usually silent, but occasionally makes puppy-like yelping noises, unlike its vocal relative, the hadada ibis.

3-12-2015 JURONG, SINGAPORE - BLACK NAPED ORIOLE (Oriolus chinensis)


The black-naped oriole (Oriolus chinensis) is a passerine bird in the oriole family that is found in many parts of Asia. There are several distinctive populations within the wide distribution range of this species and in the past the slender-billed oriole (Oriolus tenuirostris) was included as a subspecies. Unlike the Indian golden oriole which only has a short and narrow eye-stripe, the black-naped oriole has the stripe broadening and joining at the back of the neck. Males and females are very similar although the wing lining of the female is more greenish. The bill is pink and is stouter than in the golden oriole.

3-12-2015 JURONG, SINGAPORE - WESTERN CROWNED PIGEON (Goura cristata)


The western crowned pigeon (Goura cristata), also known as the common crowned pigeon or blue crowned pigeon, is a large, blue-grey pigeon with blue lacy crests over the head and dark blue mask feathers around its eyes. Both sexes are almost similar but males are often larger than females. It is on average 70 cm (28 in) long and weighs 2.1 kg (4.6 lbs).

Along with its close and very similar-looking relatives the Victoria crowned pigeon, Sclater's crowned pigeon, and Scheepmaker's crowned pigeon, it is one of the largest members of the pigeon family. The western crowned pigeon is found in and is endemic to the lowland rainforests of northwestern New Guinea; the other species of crowned pigeon inhabit different regions of the island. The diet consists mainly of fruits and seeds.


Hunted for food and its plumes, it remains common only in remote areas. Due to ongoing habitat loss, limited range and overhunting in some areas, the western crowned pigeon is evaluated as Vulnerable on the IUCN Red List of Threatened Species. It is listed in Appendix II of CITES.

The western crowned pigeon was first described by the German naturalist Peter Simon Pallas in 1764 and given the binomial name Columba cristata. A molecular phylogenetic study published in 2018 found that the western crowned pigeon was most closely related to Sclater's crowned pigeon (Goura sclaterii).

1-3-2016 - VILLALONGA RESERVOIR, VALENCIA - COMMON KINGFISHER (MALE) (Alcedo atthis)


As with all kingfishers, the Common kingfisher is very territorial, mainly because each day it has to eat about 60% of its body weight. They even defend their territory against their mates and offspring. Individuals are solitary for most of the year, roosting in heavy cover beside their favorite hunting spot. When another kingfisher comes into its territory, the birds will both sit on a perch at some distance from one another and perform territorial displays, usually the display of beaks and plumage. Fights occasionally occur, one bird grabbing the other one’s beak and trying to hold their opponent under the water. Their flight is very fast, causing their wings to seem like a blue haze. These birds communicate vocally and are well known for a long, trilling call like a repetition of the sound “chee”. During mating, the male whistles loudly to a female and will chase her through and above the trees. When diving for prey, their eyes are covered by a membrane and they rely on touch alone to know when they should snap their jaws shut.


The Common kingfisher in most parts of its range is indeed common, but it is under threat from river pollution, disturbances, and human developments. It is also vulnerable to bouts of severe winter weather, as it is unable to feed when bodies of water freeze over.
Common kingfishers serve as a good indicator of the health of an ecosystem. As they feed on small aquatic animals, toxins in the water affect them severely. A strong kingfisher population therefore usually means a healthy habitat. Common kingfishers are also important predators throughout their range of small fish from freshwater habitats, thus controlling their populations.

1-3-2016 - VILLALONGA RESERVOIR, VALENCIA - EUROPEAN MOORHEN (Gallinula chloropus)


The common moorhen (Gallinula chloropus), also known as the waterhen or swamp chicken, is a bird species in the rail family (Rallidae). It is distributed across many parts of the Old World.

The common moorhen lives around well-vegetated marshes, ponds, canals and other wetlands. The species is not found in the polar regions or many tropical rainforests. Elsewhere it is likely the most common rail species, except for the Eurasian coot in some regions.

The closely related common gallinule of the New World has been recognized as a separate species by most authorities, starting with the American Ornithologists' Union and the International Ornithological Committee in 2011.

The moorhen is a distinctive species, with 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. In the related common gallinule (Gallinula galeata) of the Americas, the frontal shield has a fairly straight top and is less wide towards the bill, giving a marked indentation to the back margin of the red area.

1-3-2016 - VILLALONGA RESERVOIR, VALENCIA - MALLARD (MALE) (Anas platyrhynchos)


Male Mallards have a dark, iridescent-green head and bright yellow bill. The gray body is sandwiched between a brown breast and black rear. Females and juveniles are mottled brown with orange-and-brown bills. Both sexes have a white-bordered, blue “speculum” patch in the wing.
Unlike larger waterfowl such as the Tundra Swan, which mate for life, Mallard pairs only stay together for a season. Courtship and pair formation begin each fall and winter. Groups of males display for a hen with a variety of behaviors, including head and tail shaking, head-bobbing, dipping, and whistling.

The female Mallard has between five and 14 light green eggs that she incubates for 30 days.

The ducklings are lead to water as soon as their soft, downy feathers are dry. ...

Most Mallard ducks live for one or two years, but some can live as long as 16 years!

Mallards swim with their tail held above the water.

1-3-2016 - VILLALONGA RESERVOIR, VALENCIA - 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.


The plumage of the Little egret is normally entirely white, although there are dark forms with largely bluish-grey plumage. In the breeding season, the adult has two long plumes on the nape that form a crest. These plumes are about 150 mm (6 in) and are pointed and very narrow. There are similar feathers on the breast, but the barbs are more widely spread. There are also several elongated scapular feathers that have long loose barbs and may be 200 mm (8 in) long. During the winter the plumage is similar but the scapulars are shorter and more normal in appearance. The bill is long and slender and it and the lores are black. There is an area of greenish-grey bare skin at the base of the lower mandible and around the eye which has a yellow iris. The legs are black and the feet yellow. Juveniles are similar to non-breeding adults but have greenish-black legs and duller yellow feet, and may have a certain proportion of greyish or brownish feathers. The subspecies nigripes differs in having yellow skin between the bill and eye, and blackish feet. During the height of courtship, the lores turn red and the feet of the yellow-footed races turn red.


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.

3-12-2015 JURONG, SINGAPORE - ASIAN GLOSSY STARLING (JUVENILE) (Aplonis panayensis)


The Asian glossy starling (Aplonis panayensis) is a species of starling in the family Sturnidae. It is found in Bangladesh, Brunei, India, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, Taiwan (introduced) and Thailand. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical mangrove forest. There is also a huge number of this species inhabiting towns and cities, where they take refuge in abandoned buildings and trees. They often move in large groups and are considered one of the noisiest species of birds. In the Philippines, it is known as kulansiyang, galansiyang, or kuling-dagat.


This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.


Fierce-looking, large songbird with a thick, decurved bill. Adult dark with greenish gloss in good light. Juvenile dark gray-brown above with a heavily streaked white belly. Most have ruby-red eyes, but birds in the central and southern Nicobar Islands have pale irises. Prefers urban and suburban areas; a common sight in cities, towns, parks, and farmland areas. Frequently seen perching on telephone wires, fence posts, and buildings, often in very large, noisy flocks. Native to Southeast and South Asia; introduced to Taiwan, where fairly common.
