Monotonous speaker curtailed by "Cor blimey, naked bird" (6,6)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

Bet you didn’t know drongo is a Madagascan word, and the bird is any of 20 or so types scattered all over Africa and Asia. The “shrike” bit appears to identify the birds as shrike-like. The wordplay is almost as much fun. Monotonous speaker, DRONE is curtailed (lose the E), cor gives rise to GOSH and then blimey translates to CRIKEY, which you denude of its outer letters.
