What is the definition of Water Wagtail?

The water wagtail is a rather cheeky little bird, basically a tiny aquatic acrobat that dances on the water's surface, flapping its iridescent wings like a butterfly on a hot summer day. It's the bird equivalent of a daredevil stunt performer, but instead of a tightrope, it's a pond!
