- Glaucidium passerinum
Identification
Length: Males 15.2-17cm (6-6.7"); females 17.4-19cm (6.8-7.5")
Weight: Males 50-65g (1.76-2.3oz); females 67-77g (2.36-2.7oz)
Mainly dark rufous to greyish-brown above, with whitish spots; breast streaked brown and off-white, with mottled brown flanks; marked white half collar around nape; tail brown to grey-brown, with 5 narrow, off-white bars; round head, no ear tufts; face whitish with brown streaks; eyes yellow; bill yellowish; legs and toes are feathered.
Variations
The subspecies orientale has paler upperparts with purer white and more sharply defined spots. Also the breast and flanks are more strongly marked brown.
Distribution
Boreal forests of Scandinavia, Finland, Estonia, Latvia, Lithuania, northwest and central Russia across to Siberia, including Sakhalin and some parts of northeastern China. Also occurring in mountains of central and eastern Europe, particularly in the Alps (France, Italy, Switzerland, Austria, Germany, Slovenia), the Carpathian Mountains (Slovakia, Romania) and the Ore mountains (Germany, Czech Republic).
Adults are generally resident, but sometimes move to lower altitudes (south) in severe winters. Immatures often roam about in Autumn and Winter, and have even been seen as far west as Britain.
Taxonomy
The Eurasian Pygmy-Owl is sometimes considered to form a superspecies with the Collared Owlet, the Pearl-spotted Owlet, the Northern Pygmy Owl and the Mountain Pygmy Owl. However, new DNA evidence denies a close relation to the Northern Pygmy-Owl of North America.
Subspecies
Two subspecies are recognized[1]:
- G. p. passerinum:
- Scandinavia, mountains of Europe to Siberia, Sakhalin and north-eastern China
- G. p. orientale:
- Central and eastern Siberia to Manchuria
They intergrade in western Siberia and the Altai Mountains.
First described by Carolus Linnaeus in 1758.
Habitat
Mainly coniferous forest in the boreal zone and corresponding montane coniferous and mixed forest in higher mountains. Prefers semi-open mature forest with clearings. Nest sites are usually found in moist or swampy areas, near a water source and with groups of younger spruces nearby.
Behaviour
The smallest European owl, it often perches at the top of trees.
Diet
Eurasian Pygmy Owls hunt for small mammals, especially voles, and small birds. They rely on surprise, sitting on a perch and waiting for their prey. They hunt tits and finches, but also woodpeckers and thrushes. Their preferred time is at dusk or dawn, but they also hunt in daylight hours and can be seen sometimes in the middle of the day, sitting on the top of a tree.
Breeding
Breeding season is from April to July. Eurasian Pygmy-Owls nest in natural holes or holes excavated by woodpeckers. They also accept nestboxes. Usually 4 to 7 eggs are laid which are incubated by the female while the male is hunting. The incubation takes about 30 days and after another 30 days the young are fledged. They're fed for another month by their parents before they are chased out of the parents' territory.
