Speak with birds

From Ardrana

The speak with birds spell empowers the priest to comprehend and communicate with any normal or giant bird that is not mindless. The priest is able to ask questions and receive answers from the creature, although friendliness and cooperation are by no means assured. Furthermore, terseness and evasiveness are likely in basically wary and cunning birds: the more stupid ones will instead make inane comments. If the bird is friendly and of the same general alignment as the priest, it may do some favor or service for the priest.

This spell originally appeared in this form in Powers and Pantheons for the AD&D game from TSR. Its use here is for the purposes of providing context for the campaign only.
