From the introduction:
"It is a well-known fact that birds play an important role in relation to agriculture. There is a general tendency to dwell on the harm they do, presumably because most land birds feed on grains, vegetable matter and fruits. The fact that most of them also feed on insect larvae, imagoes and adult insects, all of which can be pests of agriculture and horticulture, often goes unnoticed. Moreover their role as pollinating and seed dispersal agents is not fully realised or recognised, It will, therefore, seem unjust to brand them as "harmful" without evaluating the amount of good done by them compared to the harm they do. This contribution looks at Mynas (Family Sturnidae) from India."
