Crow Clone Technique

This jutsu appears to be similar to the Water Clone Technique, with the exception that after the clone has been destroyed the body will disperse into a flock of crows, which can continue to speak and maintain a physical form. The capabilities of the crow form is unknown. However, Itachi was able to cast his Sharingan Genjutsu while in clone form, so it is likely no more limited than other such clone techniques.
