It's incredible the number of nests I check that I know should have young that are empty. I don't have grey squirrels or magpies in my area so I'm sure that crows are responsible for the majority of these nests being empty. I know it's nature, but this does annoy me. Crows are at an all time high in my region and maybe there numbers are just too high. I'll probably get lambasted for this, but it's just the way I feel. Am I going over the top? |
Taking the great tit as an example, clutch size usually in the 6-11 range. If we take an average of say 8, and half were males and half were females and reached breeding status, the population could double each year with out predation and could possibly be treated as a pest specie like the house sparrow was years ago.
