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 question describes a commensal relationship where birds benefit by feeding on insects disturbed by the movement of cattle through grasses. 1. Painted Stork is primarily a wetland bird feeding on aquatic life and larger insects in marshy areas. It is not typically associated with stalking cattle in general countryside grasslands. 2. The Common Myna is an adaptable omnivore commonly found in association with humans and livestock. It is frequently observed foraging near cattle, stalking alongside them to seize insects and other small invertebrates disturbed by their movement. This behavior fits the description perfectly. 3. The Black-necked Crane is a high-altitude wetland bird, primarily feeding in marshes and meadows on plant matter, snails, insects, etc. It is not known for the specific behavior of following cattle through grasses in general countryside. Therefore, the Common Myna (2) is the bird most likely to exhibit this behavior.
