What a name to give a bird! Debilitated ignoble thrush . . . :eek!:

When scientists fail to find a suitable name for a bird, they take revenge on it.

 

[l_raty]

When scientists fail to find a suitable name for a bird, they take revenge on it.

Yet, of course:
ignobilis = obscure, insignificant (literally: not-to-be-known).
debilis = weak, feeble (literally: disabled, not-able-to-do-much).

The meaning is closer to "lesser insignificant thrush" than to "debilitated ignoble thrush".
