Immature yellow Wagtail along the North Denes

On Saturday 18th July, in the afternoon, I was walking along the North Denes trying several paths when I was walking back along the middle path back to Links Road car park, I saw the fine immature Yellow Wagtail suddenly fly up and appeared further along the path, it was very flighty as it wouldn't tolerate any close approach and twice more it flew further along the path. Finally it perched on the bushes by the Links Road car park where I was able to get closer and took a few pics albeit slightly into the sun.
