I'm fairly sure Hawks are unable to see invisible animals. Even after scouting a region with a Hawk I've often been surpried by Spiders.
Having a bird specialize in spotting invisible units would be a good addition to the game. I'd suggest that the new bird not have the abilioty to scout, forcing you to choose between carrying a Hawk or an Eagle (or whatever).
Heck, we could eventually even have 4 or 5 birds to choose from.
Of course, this would be a huge boost to the Scout class, so maybe the ability to carry birds would become a promotion instead of coming for free.
