Long-tailed Tit (Aegithalos caudatus)

Yes, I believe this to be a common bird for you living in the UK, however its' a lifer for me. It was really quite difficult to get a picture of these fellows as they almost never stay still. Some visitors were watching me with amusement as I went about after the bird. Yes, London Wetland Centre was a very enjoyable place to be in, I spent two days there, also met an old english gentleman centre volunteer who had lived in Singapore during his army days.
