Yellow- browed first one of the autumn!

On the early evening of Thursday September 27th, met Joshua C staring at the bush where The "Ninja" Yellow-browed Warbler still in favoured bush just south of 1st shelter belt south of Links Rd car park along North Denes slope seeing off all Chiff- Chaffs straying into its vigorously defended territory! Seen well but briefly about 4 times and also seen in flight chasing off all the Chiff- Chaffs! Also the Barn Owl hunting behind us on the N. Denes as well. YBW called as well around 10 times.
