The bird~~-beak~~ beak sign of the oesophagus is used to refer to the tapering of the inferior oesophagus in achalasia. The same appearance (although it is difficult to see the similarity) is also referred to as the rat-tail sign.

The appearances although classically occurring in primary achalasia, can also occur in pseudoachalasia due to a gastric tumour involving the gastro-oseophageal junction.
