23-3-2015 PENANG, MALAYSIA - COMMON FLAMEBACK (Dinopium javanense)


The common flameback (Dinopium javanense), also referred to as the common goldenback, is a small (28–30 cm), three-toed woodpecker in the family Picidae, found throughout South and Southeast Asia.

As shy and secretive birds, common flamebacks are unlikely to be found in urban areas. They live in a variety of habitats, ranging from moist open forests, to scrubs, and mangroves. Although they generally enjoy lowlands, they can reach altitudes of 1700m above sea level in India and in those cases prefer living in pine forests.

Their distribution ranges across Southeast Asia, from the Western Ghats in India to the Indochinese peninsula and several of the Greater Sunda Islands.

19-3-2015 JURONG, SINGAPORE - AMERICAN FLAMINGO (Phoenicopterus ruber)


The American flamingo (Phoenicopterus ruber) is a large species of flamingo native to the West Indies, northern South America (including the Galápagos Islands) and the Yucatan Peninsula. It is closely related to the greater flamingo and Chilean flamingo, and was formerly considered conspecific with the greater flamingo, but that treatment is now widely viewed (e.g. by the American and British Ornithologists' Unions) as incorrect due to a lack of evidence. It is also known as the Caribbean flamingo, although it is also present in the Galápagos Islands. It is the only flamingo that naturally inhabits North America.

It is a cultural icon for the U.S. state of Florida, where it was formerly abundant in the southernmost regions, although it was largely extirpated by 1900 and is now only an uncommon visitor with a few small, potential resident populations.


The American flamingo breeds in South America (in the Galápagos Islands of Ecuador, coastal Colombia and Venezuela, and northern Brazil), in the West Indies (Trinidad and Tobago, Cuba, Jamaica, Hispaniola (the Dominican Republic and Haiti), The Bahamas, the Virgin Islands, and the Turks and Caicos Islands), and tropical and subtropical areas of continental North America (along the northern coast of the Yucatán Peninsula in Mexico, and formerly southern Florida in the United States). It is a vagrant to Puerto Rico, Anguilla, Barbados, Honduras, and (following its extirpation) Florida, although some Florida populations are now thought to be year-round residents. The population in the Galápagos Islands differs genetically from that in the Caribbean; the Galápagos flamingos are significantly smaller, exhibit sexual dimorphism in body shape, and lay smaller eggs. They are sometimes separated as Phoenicopterus ruber glyphorhynchus.

Its preferred habitats are similar to those of its relatives: saline lagoons, mudflats, and shallow, brackish coastal or inland lakes. An example habitat is the Petenes mangroves ecoregion of the Yucatán.


Like other flamingo species, American flamingos will migrate short distances to ensure that they get enough food or because their current habitat has been disturbed in some way. One habitat disturbance that has been observed to cause flamingos to leave their feeding grounds is elevated water levels. These conditions make it difficult for Phoenicopterus ruber to wade, hindering their ability to access food. The flamingos will then abandon their feeding grounds in search of an alternate food source. While the flights are not as long as other migratory birds, flamingos still fly for periods without eating.


Mating and bonding behaviors of P. ruber individuals have been extensively studied in captivity. The American flamingo is usually monogamous when selecting a nest site, and incubating and raising young; however, extra-pair copulations are frequent.

While males usually initiate courtship, females control the process. If interest is mutual, a female walks by the male, and if the male is receptive, he walks with her. Both parties make synchronized movements until one member aborts this process. For low-intensity courtships, males and females walk in unison with their heads raised. In high-intensity courtships, males and females walk at a quick pace with their heads dropped in a false feeding posture. This high-intensity courtship stops at any point if either bird turns and the other does not follow, the heads are raised, unison movements are stopped, or the pace of movement is slowed. If the female is ultimately receptive to copulation, she stops walking and presents for the male. Long-term pairs do not frequently engage in courtship behaviors or in-group display. Pairs often stand, sleep, and eat in close proximity.


Courtship is most often seen among individuals that change partners often or are promiscuous. A spectrum of pairing relationships is seen. Some birds have a long-term partner throughout the year; others form pairs during periods of courtship and nest attendance. How long a relationship lasts is affected by many factors, including addition and removal of adults, maturation of juveniles, and occurrence of trios and quartets. In most pairs, both individuals usually construct and defend the nest site. In rare cases, one individual undertakes both duties. Within trios, the dominant pair begins the nesting process by choosing and then defending the site.

20-3-2015 BOTANICAL GARDENS, SINGAPORE - YELLOW VENTED BULBUL (Pycnonotus goiavier)


The yellow-vented bulbul (Pycnonotus goiavier), or eastern yellow-vented bulbul, is a member of the bulbul family of passerine birds. It is a resident breeder in southeastern Asia from Indochina to the Philippines. It is found in a wide variety of open habitats but not the deep forest. It is one of the most common birds in cultivated areas. They appear to be nomadic and roam from place to place regularly.

The yellow-vented bulbul was originally classified in the genus Muscicapa.

19-3-2015 JURONG, SINGAPORE - SILVER EARED MESIA (Leiothrix argentauris)

                              

The silver-eared mesia (Leiothrix argentauris) is a species of bird from South East Asia.
The species is generally resident although it has been reported as a winter migrant to Nameri National Park in Assam, India, which implies that the species may be an altitudinal migrant. The species has been introduced to Hong Kong from captive stock derived from caged birds.

25-2-2015 PEGO MARJAL, ALICANTE - 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.

16-1-2015 CARTAGENA, MURCIA - GREEN PEAFOWL (Pavo muticus)



The Green peafowl (Pavo muticus) is a peafowl species native to the tropical forests of Southeast Asia. Due to their natural beauty, these birds are still sometimes targeted by the pet trade, feather collectors, and even by hunters for meat. They are a much-desired bird for private and home aviculturists, despite their rather high-maintenance care requirements.


The sexes of Green peafowl are quite similar in appearance, especially in the wild. Both males and females have long upper-tail coverts (which cover the tail itself, underneath). In the male, this extends up to 2 m (6.6 ft) and is decorated with eyespots; in the female, the coverts are green and much shorter, just covering the tail. Outside of the breeding season, however, the male's train is moulted; distinguishing the sexes during this period can be difficult unless they are observed quite up close. The neck and breast feathers (of both sexes) are highly iridescent green and resemble dragon scales. In the male, the scapular, median, and greater wing coverts are blue; the lesser coverts are green and form a triangle of scaly shoulder feathers (when the wing is closed). The secondaries are black and, in some subspecies, the tertials are brown and/or barred with a faint pattern. The female has blue lesser coverts and lacks the triangle at the wing-shoulder. Females also have neck scales fringed with copper, as well as more barring on the back, the primaries and alula. Both sexes have shafted crests, are long-legged, heavy-winged, and long-tailed in silhouette. The crest of the female has slightly wider plumes, while those of the male are thinner but taller. The facial skin is double-striped with a whitish-blue; beside the ear is a yellow-orange crescent. The dark triangle below the eye (towards the eyebrow) is bluish-green in the male, and brown in the female. Seen from a distance, they are generally dark-coloured birds with pale vermillion- or buff-coloured primaries, which are quite visible in their peculiar flight; this action has been described as a true "flapping" flight, lacking the gliding that one associates with many birds.


Green peafowl were widely distributed in Southeast Asia in the past but are now only patchily distributed in China, Cambodia, Indonesia, Myanmar, Lao People's Democratic Republic, Thailand, and Viet Nam. These birds are found in a wide range of habitats, including primary and secondary forests, both tropical and subtropical, as well as evergreen and deciduous. They may also be found amongst bamboo, on grasslands, savannas, scrub, and farmland edges. In Vietnam, their preferred habitat is dry, deciduous forest close to the water, and away from human disturbance.


Green peafowl are forest birds that usually spend time on or near the ground in tall grasses and sedges. At night family units roost in trees at a height of 10-15 m (33-49 ft). During the day they can be found in small groups spending their time foraging on the ground, drinking, preening, and resting in the shade. They look for their food by scratching around in leaf litter either early in the morning or at dusk. Green peafowl are generally silent. The males usually call from their roost sites every morning and at dawn and dusk and have a loud call of 'ki-wao'. The females' call is a loud 'aow-aa' ” repeated at short intervals; males, however, may also make a similar call.


Green peafowl are believed to be polygynous; this means that one male can mate with more than one female. However, males are solitary and do not display in leks; they are highly territorial and form harems with no pair bonds. In captivity, these birds have been observed to be strongly monogamous (one male to one female). Breeding occurs between April and June and during this time males perform courtship displays to attract the female. When the pair is formed, the birds will nest on the ground in a very protected site laying 3 to 6 eggs. Incubation usually lasts during 26-28 days by the female alone. Chicks are precocial; they are hatched with their eyes open and are able to leave the nest very soon after hatching. The young can fly 2 weeks after hatching but usually remain in the family group until the next breeding season.


Green peafowl are threatened due to loss of habitat and hunting for their beautiful feathers as well as for food. Although there is no natural range overlap with the Indian peafowl, hybridization is still another threat where the Indian peafowl is introduced as they produce fertile hybrids. In captivity, hybrids are called "Spalding" peafowl and are used by breeders to create different breeds. Through backcrossing, some hybrids become almost indistinguishable from pure Green peafowl. As the species as a whole is sometimes called "Java peafowl" in aviculture, the subspecies of Green peafowl are also mixed in captivity and there are many captive birds of unknown provenance. In some areas of their native range, captive Green peafowl have sometimes been released in the vicinity of a breeding station even though their true origins remain unknown. Wild Green peafowl also suffer from poisoning in some areas as they are regarded as a crop pest by farmers.


Population numberAccording to the IUCN Red List, the total Green peafowl population size is around 15,000-30,000 individuals. This includes 10,000-19,999 mature individuals. Currently, this species is classified as Endangered (EN) on the IUCN Red List and its numbers today are decreasing.
