Abstruse Goose: Tradeoff

AG has found a fatal flaw in one of the Just-So stories that naturalists tell, that is, they’re either saying that creatures in fancy dress get sexually selected while the ones in sweats and sneaks don’t; or else they’re saying creatures in quiet camouflage don’t get noticed and eaten.  So which is it?  I can think of cases where both are true — swanky male goldfinches vs little grey-brown sparrows that look like dead leaves.  C’mon naturalists, I’m waiting.
