Distribution and biology of goshawk (Accipiter gentilis L.) in the Chřiby Upland, the Czech Republic

Popis výsledku v původním jazyce

In 2002-2006, mapping the goshawk (Accipiter gentilis L.) population was carried out at the SE edge of the Chřiby Upland. At the same time, the food spectrum of the predator was determined in detail in 2004. The studied area amounted to about 30 km2. Inthe area, 5 nest localities occurred. The size the home district of one couple was determined to be on average 3.5 to 5.5 km2. The food spectrum was analysed according to leftovers of food in nests and in the vicinity of the nests. In total, 387 leftovers of food were found. Birds represented 52%, mammals 42% and other animals (insect, reptiles etc.) 6% of prey. The population of goshawk was monitored from the period of a wedding flight to a period when young birds left their nest during the period of five years. The number of eggs was on average 2.9 per one nest. The total number of laid eggs was 73 during five years. The number of brood was on average 2.7 per one nest. Sex ratio was 47/53 per cent in favour of males. The total number
