Scientists have found that the number of birds feeding on insects has dropped significantly in Europe over a 25 year period – even more reason to protect insect populations.
The study included data from 1990 to 2015 and found a 13 per cent decrease in the number of insect-eating birds in Europe.
The scientific paper which was published in journal Conservation Biology attributed the decline to loss of grasslands and the use of land for agricultural uses.
Omnivorous birds have not declined as much as birds that feed on insects. Insectivore populations in Europe have however significantly declined.
