YBW Number 3?

After the torrential rain of yesterday, I was keen to get out this morning and it just felt rare! Sadly, I only had an hour before I had to head off for some survey work. A quick check of the West Cliffs produced 3 Mistle Thrushes, 5+ Chiffchaff and more Robins and Goldcrests than recent days. Redpoll and Siskin overhead. Then, just as I was about to leave a Yellow-browed Warbler called from pretty much the exact same spot as the one I found on 7th October. I am guessing this is most likely a new bird as I haven't seen that bird since 11th October, but I would like to see it to be sure.
