With light brown eyes, the Common Myna possesses keen vision, allowing it to spot food sources and potential threats from a distance. This acute eyesight is essential for survival in its natural environment, aiding navigation and hunting.
Habitat and Distribution of the Common Myna
The Common Myna (Acridotheres tristis) is a highly adaptable species with a remarkable ability to establish populations in diverse environments across the globe. Here’s a summary of their habitat and distribution:
Origin
Native to Asia, particularly in the Indian subcontinent and Southeast Asia.
Global Spread
Introduced to various continents and countries for pest control and other purposes. The timeline of their introduction to different regions includes:
- Australia: Introduced in 1862.
- New Zealand: Introduced in 1874.
- South Africa: Introduced in 1902.
Habitat Preference
Common Mynas prefer urban areas where human settlements provide abundant food resources. However, they also adapt to various natural habitats such as forests, grasslands, and rural landscapes.
Expansion and Success
Common Mynas have shown remarkable success in rapidly expanding their territories post-introduction. They have become one of the most widespread bird species in regions where they have been introduced, demonstrating their adaptability and resilience.
Ecological Impact
While their success as an invasive species is noteworthy, it has consequences for local biodiversity. Their aggressive nature can lead to the displacement of native bird species and disruption of ecosystems, posing challenges for conservation efforts.
Behavior and Vocalizations of the Common Myna
The behavior and vocalizations of the Common Myna (Acridotheres tristis) indeed offer a fascinating glimpse into the complexity of this species:
Social Behavior
Common Mynas exhibit complex social behaviors similar to other members of the Starling family. They are territorial during the breeding season but form communal roosts outside this period.
Aggressive displays and confrontations determine a social hierarchy within their groups.
Vocal Abilities
Common Mynas are known for their impressive vocal abilities, showcasing various calls and songs. These include soft warbles, harsh squawks, and various other sounds.
Notably, they are adept mimics capable of imitating human speech and replicating man-made sounds such as car alarms.
Repertoire
Anecdotal evidence suggests that a single Common Myna can produce up to 18 distinct calls, including:
- Alarm call: A harsh ‘kruk-kruk’
- Contact call: Soft ‘pree-pree’ or ‘preer-preer’
- Distress signal: Loud screeching
- Song: Varied and often intricate
Regional Variations
There are regional variations in the calls and vocalizations of Common Mynas, indicating their adaptability and ability to adjust to different environments and social contexts.
