Like many in the corvid family Rooks are attached to many legends, myths, lore and superstitions. In Shropshire, it was believed that rooks never carried sticks to their nests on Sundays or Ascension Day, but simply sat quietly on trees and did not work. It was also believed to be futile to wear new clothes on Easter because the rooks would fly above and poop on them.
Quite the opposite was said to be true as well. Some believed if you were hit by bird poop it was because you did not wear new or nice enough clothes on Easter. It was the Rook that was believed to make the decision if your Easter attire was nice enough. And it was the Rook who would carry out the punishment as well. It was a dirty job but somebody had to keep those English people well dressed on Easter.
Rooks deserting a rookery were (and in some places still are) also thought to be an indication of a death coming. They were also looked to for predicting weather conditions for many. Such was the case in Devon, England where it was assumed that should the Rooks stay in the vicinity of their nests in the middle of the day, or return to the rookery early, then rain would follow, but if they flew far away, then fine weather would follow instead. And in Yorkshire, the saying went that if the rooks congreated on dead branches of trees, rain wuold come before nightfall, but if they perched on live branches it would be fine and dry.

The rook is a predatory bird, cunning and intelligent, it will do most anything to survive. This is true for most corvids. But because of its sneaky nature it has gotten a reputation. The root of its name “rook” means ‘to rook’ or cheat someone. The distrust for rooks has long since held true in many places. In 19th century London a criminal ladened slums in the East End were referred to as a ‘rookery’. This was indicative of the rook’s sneaky nature but also a comment on the way they build their nests very close together—crowding in—similar to the slums. The name Rook is descendant of the Latin word frugilegus which means acquisitive. Fitting for the bird as Rooks often like to take objects including twigs and other nesting materials from other nests. ((Tate, Peter (2008). Flights of Fancy: Birds in Myth, Legend and Superstition.
