Hi thank you for asking the question
If the number of insect eating birds reduces there are many ways hoe the ecosystem will be effected
First of all if the insect decrease the food available for there natural predators i.e the birds will be decreased and due to the shortage of food the number of birds will also fall down eventually
Due to the increase in number the damage caused by the birds to the plants and the fields will increase causing loss to the farmers.
