1. ciconia — de Vaan
ciconia 'stork' [f. a] (P1.+) Derivatives: conea 'stork' (PL True. : 'Praenestinis conea est ciconia9). Cannot be connected with canire 'to sing', unless via *kph2n-. But I doubt that anyone would refer to the bill-clattering of a stork as 'singing' - unless in a very ironic way. The reduplication is probably part of the onomatopoeic formation, as in cicada.
