| Re: Pigeons and their drinking habits I've been in touch with the RSPB and they've given me this explanation.
Apparantly all birds have tongues although they are significantly different from the equivalent mammalian structure, this means that most birds do not have the muscle structure to drink continuously and have to use gravity to do the work. The pigeons do not have an extensive tongue but they have a different muscle structure in the throat due to their communication abilities and it is this that allows continuous drinking. |
