Distribution and biology of goshawk (Accipiter gentilis L.) in the Chřiby Upland, the Czech Republic
In 2002–2006, mapping the goshawk (Accipiter gentilis L.) population was carried out at the SE edge of the Chřiby Upland, the Czech Republic. At the same time, the food spectrum of the predator was determined in detail in 2004. The studied area amounted to about 30 km2. In the area, 5 nest localitie...
