Dave and John,
I'ld like to thank you for spotting my deliberate mistake so quickly and pointing it out. However, haveing seen a yellow looking wagtail i just assumed it would be a yellow wagtail. How strange to have two yellow types and one being called grey. I had a look in the
Gallery and now know that a real yellow wagtail also has a yellow head.
I will be more careful next time and check before posting. I've leant something new today.
Thanks guys
BWD
