Laughing dove

The laughing dove, known scientifically as Spilopelia senegalensis, is a small and slim pigeon. This bird is a resident breeder across many warm regions. It lives in Africa, the Middle East, and South Asia. It has also established itself in the wild in Western Australia. These birds prefer dry scrub and semi-desert habitats. They are often found in dry farmland or near human homes. Because they live near people, they can become very tame.

To understand how these birds live, we can look at their daily habits. They are mostly terrestrial, which means they spend much of their time on the ground. They forage in grasslands to find food. They eat fallen seeds, mostly from grasses, and other vegetable matter. They also eat small ground insects like termites and beetles. When they need water, they fly to waterholes. Like other members of the pigeon family, they can suck up water at the edge.

Reproduction for the laughing dove involves a very specific process. Both parents work together to raise their young. The male finds twigs and brings them to the nest. The female then places the twigs to build a flimsy platform. This nest is often built in a low bush or in crevices. The female lays two eggs, usually one day apart. Both parents help with incubating the eggs and feeding the babies. The eggs hatch after about 13 to 15 days. The young are altricial, meaning they are born helpless and need constant care. They are fed regurgitated crop-milk, which is a secretion from the parents' crop. The young birds fledge and leave the nest after 14 to 16 days.

Scientists have categorized several subspecies based on small differences in size and plumage. These populations live in different parts of the world. S. s. phoenicophila lives from Morocco to northwest Libya. S. s. aegyptiaca lives in the Nile Valley and is larger than other types. S. s. senegalensis is found in Africa south of the Sahara and west Arabia. S. s. cambayensis lives in parts of India and Pakistan. Finally, S. s. ermanni is found in places like Kazakhstan and China.

The history of studying this bird involves several famous naturalists. In 1760, the French zoologist Mathurin Jacques Brisson described the bird. He based his description on a specimen from Senegal. Later, in 1766, the Swedish naturalist Carl Linnaeus included it in his work, Systema Naturae. Linnaeus gave it the name Columba senegalensis. For a long time, the bird was placed in the genus Streptopelia. However, a molecular phylogenetic study in 2001 changed this classification. Scientists moved the bird to the genus Spilopelia. This name was originally introduced by Carl Sundevall in 1873.

An adult laughing dove has very distinct physical features. It has a long tail and bright red legs. The underside is pinkish brown, and the head has a lilac tint. Adults have a special patch on the sides of their necks. This patch is made of split feathers that look like a checkered necklace. This necklace is rufous and grey. Young birds do not have this neck marking yet. The bird is also known for its unique call. It makes a low, rolling sound that sounds like a chuckle.

The laughing dove is part of a larger, complex ecosystem. It faces many different challenges in the wild. Some birds, like the Jacobin cuckoo, may lay eggs in their nests. Predators such as the southern grey shrike or the lizard buzzard hunt them. They can also be affected by parasites, such as bird lice or the blood parasite Trypanosoma hannae. In Australia, some populations face a virus similar to psittacine beak and feather disease. Despite these challenges, they remain a widespread and common species.
