No Tawny Owls currently listed for placement
The Tawny Owl (Strix aluco) is a stocky, medium-sized owl which is common in woodlands across much of Eurasia. Its underparts are pale with dark streaks, and the upperparts are either brown or grey, with several of the eleven recognised subspecies having both variants. The nest is typically in a tree hole, and eggs and young are fiercely defended against potential predators. This owl is non-migratory and highly territorial, and many young birds starve if they cannot find a vacant territory once parental care ceases.
The Tawny Owl is a robust bird, 37-43 cm (14.5-17 in) in length with an 81-96 cm (32-38 in) wingspan. Its large rounded head lacks ear tufts, and the facial disc surrounding the dark brown eyes is usually rather plain. The nominate race has two morphs which differ in their plumage colour, one form having rufous brown upperparts and the other greyish brown, although intermediates also occur. The underparts of both morphs are whitish and streaked with brown. This species is sexually dimorphic; the female is much larger than the male, 5% longer and more than 25% heavier.
The Tawny Owl flies with long glides on rounded wings, less undulating and with fewer wingbeats than other Eurasian owls, and typically at a greater height. As with most owls, its flight is silent due to its feathers' soft, furry upper surfaces and a fringe on the leading edge of the outer primaries.
