Common myna

The common myna (Acridotheres tristis), often referred to as the Indian myna or Afghan starling, is a member of the Sturnidae family in the order Passeriformes. Listed as one of the world's most invasive species, it has become a significant agricultural pest, causing economic losses in various regions where it has successfully established populations.

This bird is highly opportunistic, feeding on a wide variety of plant and animal sources. In agricultural environments, it infests vineyards, stone fruit orchards, and berry plantations. It causes substantial damage to crops by pecking at ripening fruits, which significantly reduces both the quality and the quantity of the marketable harvest.

The biology of the common myna is characterized by a high degree of ecological plasticity. They are highly territorial, nesting in tree cavities or man-made structures. They have a prolonged breeding season and are capable of multiple clutches per year, which, combined with high chick survival rates, leads to rapid population growth and expansion into new agricultural areas.

The impact of common myna is not limited to physical destruction of produce. By damaging the skin of fruits, they leave them susceptible to secondary infections, such as fungal rots, leading to post-harvest losses. Furthermore, they are highly aggressive and displace native bird species, causing ecosystem imbalances that can indirectly affect natural pest control processes on farms.

Integrated pest management strategies to mitigate damage include:

• Deployment of agricultural netting to physically exclude birds from crops.
• Utilizing bioacoustic devices that broadcast predator calls to deter flocks.
• Installation of physical deterrents on farm infrastructure to prevent nesting.
• Strategic management of water sources and waste food to reduce the attraction of the site to the birds.
