Can anyone identify this bird, depicted in an unsigned watercolour probably made in 18th century? It is labelled "The Water Lark or Bather" but I can only find one late 19th century source which equates "Water Lark" with Water Pipit (that is, about a century after this painting would have been completed). If the painting is life-size, which is very likely, the bird's height was around 12cm and the length (tip of tail to tip of beak) was around 17cm. The source of the specimen is not stated but the painting is associated with either England or (?eastern) North America.
