Birder's Bonus 216

'Alfie', a Eurasian eagle owl (Bubo bubo) is reportedly terrorising Norfolk. It's a frisky time of year and he's given to dive-bombing joggers etc (https://www.theguardian.com/environment/2022/mar/11/he-swoops-to-conquer-hormonal-owl-livens-up-norfolk-nights). 'Alfie' weighs about 4 kg with a wingspan of 2 M. Eurasian eagle owls are no longer native to the UK. 'Alfie' apparently escaped from an aviary in 2020 and seems to be thriving in the 'wild'. Escaped members of this species have even bred successfully in the UK (presumably when they have not been imprinted on their human handlers?).
