how did the farmers suffer after they killed al the birds eating their crops
Answers
Answer:
1. They provide pest control.
Modern history is filled with stories of birds saving potato fields, fruit orchards, and cranberry bogs from insect devastation. Now researchers are studying the phenomenon more formally, trying to quantify birds' value as living pest controllers.
Consider the case of the coffee berry borer. These tiny insects invade individual coffee berries and spend almost their entire lives inside, making those beans unsellable. There are no safe pesticides that kill the insects, and attempts to control them with parasitic wasps have shown, at best, limited success.
But black-throated blue warblers, American redstarts, and other birds feast on the borers when the insects are first drilling into the berries. A researcher at one site in Jamaica's Blue Mountains calculated the birds' pest-control value at $125 per acre, or nearly one-eighth of the total crop value of $1,044 per acre.
