Remove or control predators to enhance bird populations and communities Bird Conservation

A meta-analysis of 20 published studies (Côté & Sutherland 1997) showed that predator removal had a large, positive effect on hatching success – with removal areas showing higher hatching success on average than 75% of control areas – and led to a significant increase in post-breeding population size (i.e. autumn density), although no significant impact was detected on breeding population size.
