Streptopelia ( Tekukur ) in Malaysia
Columbidae is a bird family consisting of pigeons and doves. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks, and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms.
The family contains 344 species divided into 50 genera. 13 of the species are extinct.
In English, the smaller species tend to be called "doves" and the larger ones "pigeons". The distinction is not consistent, however, and does not exist in most other languages.
Streptopelia is a genus of birds in the pigeon and dove family Columbidae. The genera Spilopelia and Nesoenas were formerly placed in Streptopelia, but have since been separated out.
Streptopelia contains 13 species. S. tranquebarica and S.bitorquata are found in Malaysia.
Spilopelia contains 2 species. Only S. chinensis is found in Malaysia.
Neosoenas contains 3 species, of whih one is now extinct. None is found in Malaysia.
Pigeon ( Merpati ) in Malaysia
Columbidae
is a bird family consisting of pigeons and doves. It is the only family in the
order Columbiformes. These are stout-bodied birds with short necks, and short
slender bills that in some species feature fleshy ceres. They primarily feed on
seeds, fruits, and plants. The family occurs worldwide, but the greatest
variety is in the Indomalayan and Australasian realms.
The family contains 344 sapecies divided into 50 genera. 13 of the species are extinct.
In
English, the smaller species tend to be called "doves" and the larger
ones "pigeons". The distinction is not consistent, however,
and does not exist in most other languages.
There are 35 species recognised in the genus of which 2 are extinct. 2 species are found in Malaysia : Columba livia domestica and Columba argentina.
Wild
rock doves ( Columba livia ) are pale
grey with two black bars on each wing, whereas domestic and feral pigeons ( Columba livia domestica ) vary in colour
and pattern.
Dove ( Merbuk ) of Malaysia
Columbidae
is a bird family consisting of pigeons and doves. It is the only family in the
order Columbiformes. These are stout-bodied birds with short necks, and short
slender bills that in some species feature fleshy ceres. They primarily feed on
seeds, fruits, and plants. The family occurs worldwide, but the greatest
variety is in the Indomalayan and Australasian realms.
The family contains 344 species divided into 50 genera. 13 of the species are extinct.
In English, the smaller species tend to be called "doves" and the larger ones "pigeons". The distinction is not consistent, however, and does not exist in most other languages.
Geopelia is a genus of small,
long-tailed doves in the family Columbidae. They are native to South-east Asia
and Australasia and are most often found in open country and scrubland. They
feed mainly on seeds which they find by foraging on the ground. They typically
lay two eggs in a simple nest of twigs and grass. Their plumage is mostly
greyish-brown with a pattern of spots or bars. The zebra dove and diamond dove
are commonly kept in captivity.
The genus contains five species:
● Diamond dove, Geopelia cuneate ( Australia )
● Zebra dove, Geopelia striata ( S.E.Asia )
● Peaceful
dove, Geopelia placida ( Australia,
New Guinea )
● Barred
dove, Geopelia maugeus ( Lesser Sunda
Islands )
● Bar-shouldered
dove, Geopelia humeralis ( Australia,
New Guinea )
Only Zebra dove ( Geopelia striata ) are found in Malaysia.
The zebra dove is popular in captivity and many populations have appeared outside its native range due to birds escaping or being deliberately released. It can now be found in central Thailand, Laos, Borneo, Sulawesi, Hawaii (introduced in 1922), Tahiti (1950), New Caledonia, the Seychelles, the Chagos Archipelago (1960), Mauritius (before 1768), Réunion, and Saint Helena.
Their call is a series of soft, staccato cooing notes. They are popular as pets because of their calls and cooing competitions are held to find the bird with the best voice.

Orangutan
Orangutans are great apes classified in the genus Pongo. They are the only extant genus of the subfamily Ponginae. All other genera under Ponginae were extinct : Lufengpithecus, Ankarapithecus, Sivpithecus, Gigantopithecus, Khoratpithecus.
Orangutans were originally considered to be one species. From 1996, they were divided into two species: the Bornean orangutan (P. pygmaeus, with three subspecies) and the Sumatran orangutan (P. abelii). In 2017, a third species, the Tapanuli orangutan (P. tapanuliensis), was identified.
All three orangutan species are considered critically endangered in the IUNCR Red List.
Etymology
The name "orangutan" is derived from the Malay words orang, meaning "man", and hutan, meaning "forest". The word was first attested in English in 1691 in the form orang-outang.
The orangutan was first described scientifically in 1758 in the Systema Naturae of Carl Linnaeus as Simia satyrus. It was renamed Simia pygmaeus in 1760 by Christian Emmanuel Hopp.
The name of the genus, Pongo, comes from a 16th-century account by Andrew Battel, an English sailor held prisoner by the Portuguese in Angola, which describes two anthropoid "monsters" named Pongo and Engeco. He is now believed to have been describing gorillas. French naturalist Bernard Germain de Lacépède used the term Pongo for the genus in 1799.
Phylogeny
In 2011, the Sumatran orangutan, following humans and chimpanzees, became the third species to have its genome sequenced. Subsequently in 2017, the Bornean and Tapanuli species had their genome sequenced.
Orangutans have 48 diploid chromosomes, in contrast to humans, which have 46.
Orangutans travelled from Sumatra to Borneo as the islands were connected by land bridges as parts of Sundaland during recent glacial periods when sea levels were much lower. The present range of Tapanuli orangutans is thought to be close to where ancestral orangutans first entered what is now Indonesia from mainland Asia.
