Crows and Magpies to be culled?

On Sunday I read in the newspaper that there is going to be a cull of crows and magpies who are blamed for the decline in the population of songbirds such as the yellowhammer and skylark.  The RSPB have stated that the population drop is due to other factors such as removal of habital and food sources.  I am inclined to agree, who are we to interfere with nature in such a way?
