Gunji jackdaw

A Gunji jackdaw was a large bird.

A resident of Deep Space 9 dreamt up a pair of Gunji jackdaws when everybody's dreams (and nightmares) became the truth in mid-2369 when the station's inhabitants were studied by an advanced alien species.

Odo had to herd the two jackdaws safely through the promenade.
