About the corvans

Corvans are a species of giant flightless birds (descended from present-day ravens) who use language and manipulate tools with their beaks and tongues, dextrous feet and adapted wings. They speak using their highly developed syrinxes.

They're just small enough to glide and fly short distances while carrying objects. Their leg muscles thickened because of a need to carry light cargo.

Corvans invented wheels shortly after they evolved and then spread all over the world in just a few millennia.

Vocal language

Corvan spoken language uses both the syrinx and the tongue. Since they have no lips and no teeth they cannot make labial or dental sounds. However, they can do a lot with their syrinxes and even produce two vocal tones simultaneously.

• non-tonal languages
• monotonal languages
• bitonal languages
  • some languages use simple JI ratios as suprasegmental phonemes

Sign language

Corvan sign languages mainly use tongue, wings, beaks, and feet. Deaf corvans are almost always congenitally deaf; it is very rare for a corvan to become deaf later in life, as avian cochleae are self-repairing.
