How many Javan mynas are there in the world?

The Javan myna is one of the most frequently spotted bird species in the forests of Singapore and is found in more numbers than the Common myna. Although the estimated population of the Javan myna birds was recorded to be about 168,000 in Singapore in the year 2000, their population has deteriorated vastly in Singapore, Malaysia, and Indonesia. There are only 2500 to 9000 mature individuals at present. These mynas are often confused with the jungle myna (A. fuscus) and great myna (Acridotheres grandis). To clear out this confusion, the International Ornithologist's Union suggests not to use the name "White-vented myna" to this species. Javan myna is under the direct threat of bird trade.

Where does a Javan myna live?

Javan myna (Acridotheres javanicus) is native to Java and Bali. These myna species are introduced to Taiwan, the Malay Peninsula, SE Thailand, Singapore, Borneo (Sarawak and Kalimantan), Sumatra, Puerto Rico, Lesser Sundas, and probably in Japan. They are not native to Singapore.

What is a Javan myna's habitat?

The mynas are spotted extensively in the cultivated areas, flooded grasslands, cities, plains, and fields. They move swiftly to their foraging sites and return to their roosts. They travel to the north during their periods of migration in January.

How long does a Javan myna live?

Normally, the common myna can live for about five years in the wild. However, several other species of myna have a life expectancy of about 12 years. Although the exact lifespan of Javan myna is not known, we can assume that they may live for about 5-10 years in wild habitats. However, most of the birds, who are under the threat of bird trade, succumb to harsh environments and lose their lives.

How do they reproduce?

Mynas are birds that breed throughout the year when they are provided with abundant fruits, seeds, and other food. Their peak breeding season reaches in the months of April and May. The Javan myna population is completely monogamous. Males start showcasing various acts of courtship displays and also engage themselves in duels with other birds. They became extremely vocal and territorial during their breeding season. Both male and female individuals build their own nests made of grasses and other similar materials and tuck their roosts within a naturally-made tree hole. This height is usually about 32 ft (10 m) from the ground. Other areas where they settle their nests are the crown of the palm, in the base of a bird's-nest made of fern, within the holes of the wall, bridge, building, or other man-made structures. Due to this, it is also called Javan myna cavity dweller. Their clutch size is usually about two to five eggs. Javan myna eggs are slightly bluish in color and their incubation period is about 13-14 days. Javan myna juvenile is browner than the parents.

What is their conservation status?

According to the IUCN Red List, the Javan myna (Acridotheres javanicus) is a Vulnerable species. Their population trend is decreasing day by day. Human activities including bird trade, climate change, lack of a safe environment, and scarcity of food have culminated into their significant drop in population. These bird species and their eggs are also attacked by birds of prey like eagles, vultures, and hawks.
