27-5-2023 TABIN RESERVE, BORNEO - CHANGEABLE HAWK EAGLE (Nisaetus cirrhatus)


The changeable hawk-eagle (Nisaetus cirrhatus) or crested hawk-eagle is a large bird of prey species of the family Accipitridae. More informal or antiquated English common names include the marsh hawk-eagle or Indian crested hawk-eagle. It is a member of the subfamily Aquilinae, with signature feathers, absent in tropical raptors from outside this subfamily, covering the tarsus. It was formerly placed in the genus Spizaetus, but studies pointed to the group being paraphyletic resulting in the Old World members being placed in Nisaetus and separated from the New World species. It is a typical “hawk-eagle” in that it is an agile forest-dwelling predator and like many such eagles readily varies its prey selection between birds, mammals or reptiles as well as other vertebrates. Among the members of its genus, the changeable hawk-eagle stands out as the most widely distributed, adaptable and abundant species. Individuals show a wide range of variation in plumage from pale to dark, varying with moult and age giving rise to the name "changeable". 

18-5-2023 SEPILOK, BORNEO - SOUTHERN PIG TAILED MACAQUE (Macaca nemestrina) (FEMALE) (COURTESY OF MRS VALERIE FISHER)


The southern pig-tailed macaque (Macaca nemestrina), also known as the Sundaland pig-tailed macaque and Sunda pig-tailed macaque, is a medium-sized macaque that lives in southern Thailand, Malaysia, and Indonesia. It is known locally as berok.

M. nemestrina is mainly terrestrial, but also a skilled climber. Unlike almost all primates, these macaques love water. They live in large groups that split into smaller groups during daytime when they are foraging. They are omnivorous, feeding mainly on fruits, seeds, berries, cereals, fungi, and invertebrates. A study in peninsular Malaysia found them to be the primary, and perhaps the only, seed dispersers of the rattan species Daemonorops calicarpa and Calamus castaneus.

There is a hierarchy among males, based on strength, and among females, based on heredity. Thus, the daughter of the alpha female will immediately be placed above all other females in the group. The alpha female leads the group, while the male role is more to manage conflict within the group and to defend it.

Female gestation lasts around 5.7 months. She will give birth to one infant every two years. Weaning occurs at 4–5 months. Sexual maturity is reached at 3–5 years.

In Thailand, they have been trained for 400 years to harvest coconuts.

This macaque is mostly found in rainforest up to 2,000 metres (6,600 ft), but will also enter plantations and gardens.

It is found in the southern half of the Malay Peninsula (only just extending into southernmost Thailand), Borneo, Sumatra and Bangka Island. There are reports of the species having been present in Singapore before 1950, but these were likely escaped pets. The only pig-tailed macaques in Singapore today are introduced monkeys.

18-5-2023 SEPILOK, BORNEO - BLUE THROATED BEE-EATER (Merops viridis)


Blue-throated bee-eaters practice asynchronous brooding, which means that chicks hatch at different times, often pairing with siblicide. Older chicks are not only larger and able to withstand larger wounds from other siblings, but also have the ability to monopolize the food they are fed by parents. There has been several observations of migration between islands in southeast Asia or onto mainland of Asia. One notable seasonal spring migration occurs from Sumatra, across the Strait of Malacca, and ending on the west coast of Malaysia. They also migrate from southeast Asia to breeding grounds in western China during breeding season.

Conservation status of the blue-throated bee-eaters is of "least concern" due to their large distribution and stability of its population as of 2016. However, deforestation may be its biggest threat, destroying its habitat and decreasing other bird diversities.

28-5-2023 TABIN RESERVE, BORNEO - NORTH BORNEAN GREY GIBBON (Hylobates funereus) COURTESY OF MRS VALERIE FISHER

The eastern grey gibbon or northern grey gibbon (Hylobates funereus) is a primate in the gibbon family, Hylobatidae.

Formerly, the eastern grey gibbon and western grey gibbon (H. abbotti) were considered conspecific with the southern grey gibbon (H. muelleri), but more recent studies indicate that all three are distinct species, and both the IUCN Red List and the American Society of Mammalogists consider them such. However, they can still hybridize with one another where their ranges meet.

 It is endemic to northeastern Borneo, and is found in Kalimantan, Sarawak, and Brunei. It ranges from Sabah south to the Mahakam River in East Kalimantan, and west to Baram in Sarawak. 



23-5-2023 SAKAU RIVER LODGE, BORNEO - STORM'S STORK (Ciconia stormi)


This stork was first described by Blasius in 1896, and named after the German sea captain Hugo Storm, a collector of zoological specimens in the West Indies. In Thailand, it is known as "nok kra su um", which refers to the birds’ fishing procedure by stalking along the bank of a stream in dense forest.

This species is very similar and closely related to the woolly-necked stork whose range partially overlaps with that of Storm's stork. Although Storm's stork has long been considered a separate species, it has also been previously treated as a subspecies of the woolly-necked stork in the more recent past. However, Storm's stork is characterised by a yellowish-orange facial skin patch around the eye that is absent in the woolly-necked stork; and the neck is black and white, whereas it is completely white in the woolly-necked stork.
The bulk of the world population of this stork occurs on Borneo; occurring in Kalimantan (Indonesia), Swarak, Sabah (Malaysia) and Brunei. It is also found throughout Sumatra, although its range there was previously considered to be restricted to the south east. Despite being widespread on both of these islands, the population occurs at low densities and only one or a few individuals have ever been sighted together, with the largest number being 12 during an observation in Brunei. Smaller numbers live in some parts of peninsular Malaysia, where it appears to be particularly rare.

Pomacea maculata is a species of large freshwater snail with an operculum, an aquatic gastropod mollusk in the family Ampullariidae, the apple snails.

The common name of its synonymous name Pomacea insularum is the island applesnail.

Together with Pomacea canaliculata it is the most invasive species of the family Ampullariidae. It is considered as about the 58th worst alien species in Europe. 

10-6-2023 SINGAPORE GARDENS - SCARLET SKIMMER DRAGONFLY (MALE) (Crocothemis servilia)

The scarlet skimmer or ruddy marsh skimmer, Crocothemis servilia, is a species of dragonfly of the family Libellulidae, native to east and southeast Asia and introduced to Jamaica, Florida, and Hawaii.

It is a medium sized blood-red dragonfly with a thin black line along the mid-dorsal abdomen. Its eyes are blood-red above, purple laterally. Thorax is bright ferruginous, often blood-red on dorsum. Abdomen is blood-red, with a narrow black mid-dorsal carina. Anal appendages are blood-red. Female is similar to the male; but with olivaceous-brown thorax and abdomen. The black mid-dorsal carina is rather broad.

It breeds in ponds, ditches, marshes, open swamps and rice fields.


10-6-2023 SINGAPORE GARDENS - ORIENTAL MAGPIE ROBIN (Copsychus saularis)


The Oriental magpie-robin (Copsychus saularis) is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but now considered an Old World flycatcher. They are distinctive black and white birds with a long tail that is held upright as they forage on the ground or perch conspicuously. Occurring across most of the Indian subcontinent and parts of Southeast Asia, they are common birds in urban gardens as well as forests. They are particularly well known for their songs and were once popular as cagebirds.

The oriental magpie-robin is considered the national bird of Bangladesh.

25-7-2023 MONTE CORONA, VALENCIA - SOUTHERN GREEN STINK BUG (Nezara viridula),


Nezara viridula, commonly known as the southern green stink bug (USA), southern green shield bug (UK) or green vegetable bug (Australia and New Zealand), is a plant-feeding stink bug. Believed to have originated in Ethiopia, it can now be found around the world. Because of its preference for certain species of legumes, such as beans and soybeans, it is an economically important pest on such crops.

Several distinct morphs can be distinguished by the pattern of their exoskeleton coloration. The most common morph is predominantly green (Nezara viridula f. smaragdula), a less common morph is green with white or yellowish front margins on the head and the thorax (Nezara viridula f. torquata Fabricius, 1775) and a very rare morph has a uniformly orange or yellow (occasionally pink) coloration (Nezara viridula f. aurantiaca).

25-5-2023 SUKAU, BORNEO - JUNE BEETLE (Subfamily Melolonthinae)

Melolonthinae is a subfamily of the scarab beetles (family Scarabaeidae). It is a very diverse group; distributed over most of the world, it contains over 11,000 species in over 750 genera. Some authors include the scarab subfamilies Euchirinae and Pachypodinae as tribes in the Melolonthinae.

Unlike some of their relatives, their habitus is usually not bizarre. They resemble the Rutelinae in being fairly plesiomorphic in outward appearance. Like in many Scarabaeidae, males have large fingered antennae, while those of the females are smaller and somewhat knobby. In the Melolonthinae, this sexual dimorphism is particularly pronounced. Many species have striking – though rarely brilliant or iridescent – hues and bold patterns of hairs.

Being often quite sizeable and swarming in numbers at certain times, for example the Amphimallon, Phyllophaga and Polyphylla "june beetles" or the Melolontha cockchafers – all from tribe Melolonthini – feature widely in folklore. Some Melolonthinae are economically significant pests. Other than the Melolonthini, the most diverse tribes are the Ablaberini, Liparetrini, Macrodactylini, Tanyproctini and Sericini.



 

18-5-2023 SEPILOK, BORNEO - PACIFIC SWALLOW (Hirundo tahitica)


 The Pacific swallow (Hirundo tahitica) is a small passerine bird in the swallow family. It breeds in tropical southern Asia and the islands of the south Pacific. It is resident apart from some local seasonal movements. This bird is associated with coasts, but is increasingly spreading to forested uplands. The hill swallow and the welcome swallow were formerly considered conspecific.

23-7-2023 RIO SERPIS VILLALONGA, VALENCIA - LITTLE EGRET (Egretta garzetta)

The adult little egret is 55–65 cm (22–26 in) long with an 88–106 cm (35–42 in) wingspan, and weighs 350–550 g (12–19 oz). Its plumage 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.


 

23-7-2023 MONTE CORONA, VALENCIA - IBERIAN GREEN FROG (Pelophylax perezi)

The Perez's frog (Pelophylax perezi), also known as Iberian waterfrog, Iberian green frog or Coruna frog, is a species of frog in the family Ranidae.

It is not considered threatened by the IUCN.


16-5-2023 KOTA KINABALU NAT PRK, BORNEO - YELLOW BREASTED WARBLER (Phylloscopus montis)


The yellow-breasted warbler (Phylloscopus montis) is a species of Old World warbler in the family Phylloscopidae. It is found in Indonesia, Malaysia, and Palawan Island in the Philippines. The species is most common on the islands of Sumatra and Borneo in Indonesia. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.

The species nests in mid-February and breeds February-April. It builds domed nests with a side entrance out of grasses and bryophytes. Nests are found among roots under the overhanging lip of an eroded bank or other similar place. It forages for food alone or with small parties of not more than five birds.

The yellow-breasted warbler was previously placed in the genus Seicercus. A molecular phylogenetic study published in 2018 found that neither Phylloscopus nor Seicercus were monophyletic. In the subsequent reorganization the two genera were merged into Phylloscopus which has priority under the rules of the International Commission on Zoological Nomenclature.

The yellow-breasted warbler has a large range and a steady population size. From the perspective of conservation biology, this species is classified as one of least concern, meaning it does not appear to be threatened or vulnerable to extinction at the present time.

16-5-2023 KOTA KINABALU NAT PRK, BORNEO - WHITE BROWED SHRIKE BABBLER (Pteruthius aeralatus)


 The white-browed shrike-babbler (Pteruthius aeralatus) is a bird species found in the eastern Himalayas and Southeast Asia from northern Burma to southern Cambodia. Like others in the genus it is found in montane forests. Males and females have different plumages and variations occur through its range with several populations being treated as subspecies. It is part of a cryptic species complex and was earlier lumped as a subspecies of the white-browed shrike-babbler. Clements lumps this bird into the white-browed shrike-babbler.

24-5-2023 SUKAU RIVER LODGE, BORNEO - WRINKLED HORNBILL (Rhabdotorrhinus corrugatus)


The wrinkled hornbill or Sunda wrinkled hornbill (Rhabdotorrhinus corrugatus) is a medium-large hornbill which is found in forest in the Thai-Malay Peninsula, Sumatra and Borneo.

This is a forest species and eats mainly fruit, such as figs, although it will also eat small animals such as frogs and insects. Wrinkled hornbills do not drink, but get the water they need from their food. Their call is a harsh "Kak-kak", or a deep "Row-wow" which can be heard for miles.

These birds are monogamous and remain in a pair for life. They use holes found in trees for nests, and the female will plaster over the entrance with mud and droppings, leaving a nesting mother and her chicks only a small hole, too small for them to exit. They are fed exclusively by the male, who regurgitates food for them. After several months, when the chicks are ready, the female will break out of her nest. 




16-5-2023 KOTA KINABALU NAT PRK, BORNEO - CHESTNUT HOODED LAUGHING THRUSH (Pterorhinus treacheri)


The chestnut-hooded laughingthrush (Pterorhinus treacheri) is a species of bird in the laughingthrush family Leiothrichidae endemic to Borneo. Described by the British ornithologist Richard Bowdler Sharpe as a distinct species in 1879, it was subsequently considered a subspecies of the chestnut-capped laughingthrush until 2007, when it was again raised to species status by the ornithologists Nigel Collar and Craig Robson. It is 22–24 cm (8.7–9.4 in) long, with a chestnut brown head and chin, with grey feathering on the top of the head. The upperparts and the side of the neck are slaty-grey, with a long white wing patch. The throat, breast, and upper belly are dull yellowish-brown, with purer grey flanks and a reddish-brown vent, lower belly, and thighs. It has a yellow half eye-ring behind and below the eye, while the tail has a blackish tip. Both sexes look similar, while juveniles are duller than adults.

The species inhabits montane and hill forest, forest edge, disturbed vegetation, and cultivated areas in mountains in the north-central and southeastern parts of Borneo. It is mainly found at elevations of 600–2,800 m (2,000–9,200 ft), but can be found down to 200 m (660 ft) and as high as 3,350 m (10,990 ft). It is omnivorous, feeding on arthropods, fruit, and flowers. Breeding occurs from February to April and in October, with the species building cup nests and laying clutches of two bright blue to greenish-blue eggs. It is classified as being of least concern by the International Union for Conservation of Nature due to its very large range, fairly large population, and a lack of significant population decline, but its numbers are thought to be decreasing and it is threatened by habitat destruction and habitat fragmentation.
