Qualitative and Quantitative Changes in a Guild of Forest Owls : Eurasian Pygmy Owl ( Glaucidium passerinum ), Ural Owl ( Strix uralensis ), Tawny Owl ( Strix aluco ), Boreal Owl ( Aegolius funereus ) at Kamenný Hrb – Bankov Sit
A guild of forest owls was evaluated in 1989 − 2021 in a 5.2 km2 site in Slovakian Volovské mountains in Western Carpathians. Only the Eurasian Pygmy Owl (Glaucidium passerinum) declined in this near 30 year period from 8 to 5 territories and that local decline is referred to the increased pr...
