On Crowdin:
string subtitles.entity.warden.ambient has text "Warden whines"
string subtitles.entity.parrot.imitate.warden has text "Parrot whines"

But in game:
Parrot doesn't whine like warden but parrot imitates warden's tendrils clicking.
It means that string subtitles.entity.parrot.imitate.warden sounds like subtitles.entity.warden.tendril_clicks.
