How many of the five species of UK owl have you ever seen? They can be notoriously difficult to track down - most of them are out and about when the rest of us are tucked up inside, they come well camouflaged, and some make their homes in hard-to-reach places.
You might be more likely to hear an owl's call than to see it in the feather, but can you tell your tawny from your barn owl by sound alone?
Tawny owl (Strix aluco)
Large black eyes Streaked brown plumage
Female: sharp 'ke-wick' Male: wavering 'hoohoo'
Best time to hear
Autumn evenings when pairs begin courting, ready for nesting as early as February. Found in woodland habitats, but also churchyards, towns and cities with mature trees.
