grey wagtail
This is a striking bird that is found next to brooks and on floodplains, but can be found also near water purification plants. This yellow bird tears up and down with its long thin tail and is therefore easily recognizable.
and they have a sharp call that is often given in flight.

White troated dipper, Grey wagtail, and a flowering creeping bellflower on an illustration from Thorburn.
White-throated dipper and the Grey wagtail occupy the same habitat (fast moving brooks) , and feed on the aquatic insects and crustaceans. But the grey wagtail is more flexible and has a much larger distribution. The white-troated dipper hunts mostly by walking above the water, clenching to the rocks, sometimes diving. The Grey wagtail walks mostly near the border and feeds mostly on flying prey.
These birds feed on a variety of aquatic invertebrates including adult flies, mayflies, beetles, crustacea and molluscs.
