Wagtails are pretty frisky and will only give a moment's notice to make an image before they move on. The image has been made well with the wagtail looking in the direction of water and the habitat nicely depicted. As Sabyasachi beautifully pointed out, the entire nexus of how one species feeds another and contributes to the entire ecosystem being maintained is critical and its good that there are some places where it can still be seen. Thanks for sharing.
