Common Myna (Acridotheres tristis)
The Common Myna (Acridotheres tristis) is a medium-sized passerine bird belonging to the family Sturnidae. It is native to South Asia but has also been introduced to other parts of the world, including Australia, New Zealand, and the United States. The Common Myna is a highly adaptable bird that can thrive in a range of habitats, including urban areas, agricultural lands, and forests.
Physical Characteristics:
The Common Myna measures around 23-26 centimeters (9-10 inches) in length, with a wingspan of approximately 35-41 centimeters (14-16 inches). It has a distinctive brownish-gray plumage, with a yellow bill and legs, and a black mask around the eyes. The bird has white patches on the wings and tail, which are visible in flight. The male and female share similar coloration and markings, with little sexual dimorphism.
Diet:
The Common Myna is an omnivorous bird that feeds on a variety of foods, including insects, fruits, seeds, and small animals. It is known to scavenge for food in urban areas, often raiding garbage cans and other waste sources. The bird is also an important pollinator and seed disperser in some areas.
Reproduction and Lifecycle:
The breeding season for the Common Myna typically occurs between December and June, depending on the location. These birds are monogamous and form pair bonds that can last for several breeding seasons. They build a nest in a variety of locations, including tree hollows, buildings, and other structures. The nest is made of twigs, grass, and other plant materials.
The female lays 4 to 6 pale blue or greenish-blue eggs, which are incubated by both parents for around 16-18 days. After hatching, the chicks are fed and cared for by both parents until they fledge, or leave the nest, at about 18-22 days old. The young birds become fully independent within a few weeks of fledging.
Conservation Status:
The Common Myna is currently listed as a species of “Least Concern” by the International Union for Conservation of Nature (IUCN) due to its wide distribution and stable population. However, the bird has been introduced to many parts of the world, where it has become a significant pest, competing with native bird species for food and nesting sites. In some areas, the Common Myna is also considered a crop pest. Efforts to control or eradicate the bird in these areas are ongoing.
