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.

Describes large numbers of cattle kept on tall grass/bushes in savanna environments where cattle are moving and grazing.

A student could combine this with the general fact that moving large grazing animals can disturb small fauna in vegetation to hypothesise birds might exploit such disturbance.

States the savanna is 'natural cattle country' with pastoralists and cattle grazing on local grasslands.

Knowing Painted Storks occur in some open wetland/grassland regions, a student might check overlap of stork range with savanna grazing areas to assess plausibility of cattle-following behaviour.

Notes that livestock farming in equatorial/highland regions is handicapped by tall coarse grass and that few animals are kept—implying varied vegetation structure where animals move through tall grasses.

A student could infer that in areas with tall grasses, animal movement could flush insects from cover and then look for observational evidence of birds taking advantage.

Describes nomadic herders migrating regularly with livestock, implying regular, large-scale movement of cattle across landscapes.

A student might extend this to consider that repeated livestock movement creates opportunities (predictable disturbances) that foraging birds could exploit, then seek species-specific foraging reports.

Mentions ranching and replacement of tufted grasses by forage crops, indicating varied grazing systems and differing vegetation that influence how animals move through and disturb ground cover.

A student could use this to reason that in some grazing regimes (open pastures) insects are more likely to be exposed by cattle movement and so check whether Painted Storks forage in such pastures.
