The Indian Roller (Coracias benghalensis) is a captivating member of the roller bird family, renowned for its striking plumage and impressive aerial acrobatics. This beautiful bird is widely distributed across West Asia, the Indian Subcontinent, and Sri Lanka, where it is a familiar sight in various open habitats. Its presence is significant, even being chosen as the state bird by several Indian states, highlighting its cultural and ecological importance.

Measuring approximately 33-33 cm in length, the Indian Roller is a medium-sized bird. Its most distinguishing feature is its dazzling array of colors, predominantly various shades of blue and green, which shimmer beautifully in the sunlight. These vibrant hues make it easily recognizable and a favorite among birdwatchers.
Habitat
Indian Rollers thrive in open grassland and scrub forest habitats. They are frequently observed perched along roadside trees and electric or telegraphic wires, using these elevated spots as vantage points for hunting. Studies on their roosting behavior reveal that after waking, they spend a few minutes preening before flying around their roosting sites. Favoured perches also include trees and shrubs, demonstrating their adaptability to different arboreal structures.

The diet of the Indian Roller is primarily insectivorous, consisting mostly of insects. However, these opportunistic hunters are not limited to insects; they also skillfully catch and consume a variety of other small prey, including small lizards, frogs, small rodents, and even snakes. This diverse diet showcases their adaptability and role as effective predators in their ecosystem.

During the breeding season, male Indian Rollers are particularly noted for their spectacular aerobatic displays. These elaborate aerial maneuvers are a key part of their courtship ritual, designed to attract mates. While specific nesting details are not provided in the data, these displays are a clear indication of their breeding activities.
