Photographing Small Birds with the Sony 200-600G Lens

With springtime well and truly here in the UK I visit a local gravel pit to try and capture images of the numerous summer migrants that have recently made there way to the UK. I don't go far and am soon surrounded by displaying Chiffchaff, Willow Warbler and Blackcap. A really enjoyable way to spend a a day close to home on a very small area of scrubland. Tell me in the comments what birds you can photograph close to your home and what's arrived for the spring. (or the season where you are, for my international friends!)
