Glaucidium Passerinum

Glaucidium Passerinum

 

a pygmy owl of the order Strigiformes; the smallest owl among the fauna of the USSR. Its body measures about 17 cm in length, and it weighs between 56 and 78 g. The back is grayish-brown with light specks and the chest is white with dark spots. The Glaucidium passerinum is found in northern and central Europe and northern Asia; in the European part of the USSR it is found in coniferous and mixed forests as far south as Riazan’ Oblast, and in Siberia, to the southern borders. In the winter it migrates somewhat to the south. It nests in tree hollows, laying 4-6 eggs. The G. passerinum feeds on mouse-like rodents and small birds, storing food in tree hollows. It is rare everywhere and is protected by law.

Six species (Charadrius hiaticula, Circus aeruginosus, Glaucidium passerinum, Emberiza calandra, Lanius collurioides and Saxicola insignis) (Table II) were deleted from the previous species checklist (Zeng et al., 2016b) because of absence of distribution evidence or species misidentification.
However, this does not cover significant parts of the habitats of 17 endangered bird species listed in Annex I of the Birds Directive, thus putting at risk the conservation of species such as Tengmalm's Boreal's owl (Aegolius funereus) and the Eurasian pygmy owl (Glaucidium passerinum), as well as the white-backed woodpecker (Dendrocopos leucotos), the three-toed woodpecker (Picoudes tridactilus), the hazel grouse (Bonasa bonasia) and the black woodpecker (Dryocopus martius).

1993), where males and subordinates were taken disproportionately often by the Pygmy Owl Glaucidium passerinum. Also, young snowshoe hares suffer more from predation by Great Horned Owls than adults (Rohner and Krebs 1996).
(3) Birds may not yet have been acclimatized to hard winter conditions (e.g., Cooper and Swanson 1994, Liknes and Swanson 1996), which [TABULAR DATA FOR TABLE 7 OMITTED] could have resulted in starvation and, hence, increased exposure to predation by, e.g., the Pygmy Owl, Glaucidium passerinum, a year-round predator of small passerines in Fennoscandia (Orell and Ojanen 1979, Jansson et al.
