The dietary laws concerning winged creatures often group species by their distinct behaviors and habitats. In this specific collection of forbidden animals, the focus rests entirely on creatures of the night. These species are classified primarily as nocturnal birds of prey [ביאור שטיינזלץ], and Talmudic tradition identifies this specific trio by the names karia, kapufa, and buta [נתינה לגר].
Beyond their nighttime hunting habits, some of these creatures share highly unusual physical traits. Two of the birds in this group are distinguished by a facial structure featuring jaws that strikingly resemble those of a human being [אדרת אליהו]. The final creature in this nocturnal trio is uniquely described as an animal completely lacking eyes [אדרת אליהו]. This distinct physical characteristic aligns with the understanding that this creature is actually a bat rather than a typical bird [רש״י].
