Pigeon and Poultry Breeders, Friends or Enemies of the Northern Goshawk Accipiter gentilis ? A Long-Term Study of a Population in Central Poland
In this study, we focused on a goshawk population in central Poland (study area 105 km 2 , forests 24 km 2 , seven small forest complexes) which was monitored long-term (with high densities recorded in the 1980s of 16.3 pairs/100 km 2 despite persecution by farmers) to analyse how environmental fact...
