Sources : Dariata
Thomas of Cantimpré [circa 1200-1272 CE] (Liber de natura rerum, Birds 5.42): Dariata, as Aristotle says, is an oriental bird. It lacks legs, using its chest, beak and other things for crawling. There is only one kind of them, which does not appear until after the rain which is at the end of summer, and appears only at this time. She makes a nest and produces young, and when she has nursed the young to flight and made them capable, she immediately dies and leaves her children, who imitate her life and death, but who will die at a later time. - [Badke translation/paraphrase]
