clamatory
Crying out, calling out; claiming, demanding.
rare
Some persons say that it [the "clivia"] was a clamatory, others, again, that it was a prohibitory, bird. We also find a bird mentioned by Nigidius as the “subis," which breaks the eggs of the eagle.
Where it comes from
Probably from the stem of Latin clamatus + -ory; equivalent to claim + -atory. Compare exclamatory, declamatory, reclamatory.
