Super intelligent crows will definitely obfuscate the fact that they are flying down to Crow generals in order to provide real-time battlefield intel. They might for example use some kind of signalling system based on flocking behaviour or drop-deliver short coded messages - crows are capable of simple tool use.

Crows feast well after a gory battle. Maybe al fresco eyeball buffets are a quid pro quo for the potentially dangerous reconnaissance of active battlefields.
