5pm start on The Lord's Birthday (and my Dad's too - 71 today!), and sitting in the employer's premises at Cramlington at 00:15hrs and I thought I heard a
Tawny Owl.
Hearing things, thinks I. And then a few moments later and there it is again. Window open and after a wee while, voila!
Went to try and and locate it better, and it was coming from the SE, so perhaps near Valley Park.
