- Behaviour
- Jays are highly intelligent, bold, and noisy, with loud, harsh alarm calls. They are primarily arboreal but often visit ground feeders and gardens. They are known for caching acorns in autumn, inadvertently aiding oak regeneration across the UK.
- •Jays can mimic the calls of other birds, including Buzzards and Tawny Owls, particularly when alarmed.
- •A single Jay can bury and cache thousands of acorns in autumn; many are forgotten and grow into new oak trees.
- •Jays have a striking pattern with bright blue wing patches, white underparts, and a distinctive black malar stripe.
- •They are the only members of the crow family (Corvidae) in the UK with predominantly warm plumage rather than black or grey.
- •Continental Jays regularly migrate to the UK in autumn in 'invasion years', sometimes in large numbers when acorn crops fail in northern Europe.
