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]

Albertus Magnus [ca. 1200-1280 CE] (De animalibus, Book 23, 38): Daryatha is, in Aristotle's words, a bird without feet. When it falls to the ground, it crawls about on its breast and the elbow-joints of its wings in much the same fashion as a bat, except that the bat has underdeveloped feet connected to its tail. This bird appears only after rainy weather at the beginning of the summer and produces its young at this season. When the fledglings mature, the parent dies and leaves the young birds heir to its pathetic existence. - [Scanlan]
