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)

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.

3-12-2015 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).
