Bird

A Bird was a type of animal, found on Earth and many other planets. Some intelligent species seem to be descended from birds, like the Jacondan, the Valnaxi, the Dethak, and the Shansheeth. The unnamed species of Mr and Mrs Pakoo was also birdlike. The planet Pheros was inhabited by intelligent robotic birds made of living metal and the Devil-Birds of Corbo were also robotic.

Birds were also used by Humans to study the effect of certain chemicals, as in the case of their use to test a new chemical weapon in 1942. (DW: The Curse of Fenric)

Birdie was named after his fondness for birds. (K9TV: Mutant Copper)

Examples of non-sentient birds include ostriches, ravens, dodos, parrots, sparrows and the didus.
