Can you tell me some signs for enemy presence/absence?

I know of the most common... *Three pile gold/stone, take diversion... *Relic, take diversion... *Four pile gold/stone, enemy is near... *>5 pile gold/stone, you are in his base... *Berries... Yay! Foun- Scout dead to TC before even finishing the sentence...

Are there any other signs? Bear in mind that this is not KOTD2 Arabia, so there are no Ostriches/Zebra distinction...
