I think this is another chiffchaff but always best to check. Help please

In my opinion it looks more like a Willow Warbler. However I'm not 100% certain. ChiffChaff is dingier, browner and less yellow in colour. Also more compact in shape. It's wings are shorter than a Willows and in my opinion your image is more reminicsent of a Willows. Your bird's tail is pointing downwards which is more characteristic of ChiffChaff but this is by no means definitive. ChiffChaff is more buff on flanks but supercilium is less strongly pronounced. This bird has a very pronounced supercilium. Leg colour is by no means a safe distinction since some ChiffChaffs have pale legs and Willows dark ones. Thanks for sharing. Nice pictures
