And it is the chirping of the sacred birds, of whom it is said: (Ecc. 10:20) For a bird of the heavens shall carry the voice, the chirping of all birds, which are the holy souls, who chirp with many prayers, the speech of the ḥayot, who are the scholars of Torah. And because of it is stated: (Gen. 24:63) And Isaac went out to converse∞su-aḥ in the field... etc. ‘And there is no ‘conversation’∞siḥah but prayer.’xvBT Berakhot 26b
