Pigeons and doves

Order Columbiformes (Pigeons)
Family Columbidae (Pigeons)
The sandgrouse used to be grouped in the same order but has since been separated (Order Pteroclidiformes) and placed between the waders and pigeons. This order contains not only pigeons but also the extinct dodos. The passenger pigeon of North America joined the extinct dodos in 1914. There is really no good distinction between pigeons and doves, although the latter are generally smaller. We'll use 'pigeon' to refer to both. Pigeons are see-eaters or frugivores. They produce crop milk to feed their chicks. The world has 308 species of pigeons.

There are 12 species to be found in Singapore. The most common is the Rock Pigeon. The Zebra and Spotted Doves are two very common brown pigeons in Singapore. They can be distinguished by their size and body patterns. The Spotted Dove is larger and has spots on the back of the neck, while the Zebra Dove is smaller and has bars at the back of the neck. The Red Collared Dove does look like a brown pigeon at a distance, but up close they look red (female looks brown) and there is a black collar instead of spots and bars. The next pigeon one is likely to encounter is the Pink-necked Green Pigeon. This is a colourful pigeon. The other 7 are uncommon or rare.

Rock Pigeon (Columba livia)

(Tan KH) (Lau SY)
Previously known as Rock Dove, it is officially known as Rock Pigeon now. It is commonly simply called 'pigeon'. In Singapore, it is feral, which means their ancestors escaped from domestication into the wild. Being highly adaptable, they have been successfully introduced to all over the world. They have many morphs, from all white to black-and-white, white-and-brown to blue-and-grey. Due to their uncanning ability to return to their point of release, they were used as homing pigeons. They were also bred for food. They are now more of a pest and their droppings carry diseases.
