If you walk through countryside, you are likely to see some birds stalking alongside the cattle to seize the insects disturbed by their movement through grasses. Which of the following is/are such bird/birds? 1. Painted Stork 2. Common Myna 3. Black-necked Crane Select the correct answer using the code given below.

The Common Myna is an opportunistic feeder that frequently follows grazing cattle to seize insects flushed out from the grass, a classic example of a commensal relationship. In contrast, Painted Storks and Black-necked Cranes are primarily wetland-dependent species that feed on aquatic prey or forage in high-altitude marshes rather than following livestock in the countryside. This question tests the core concept of **commensalism** and the specific foraging behaviors of common Indian avifauna.
