'It seems that the archers in this fight stood up there... they fired many arrows, so I guess they did fire upon the melee uninterrupted. It's and about seventy feet up hill. A bunch of kobolds if you ask me. Luthal maybe you can make more sense of the tracks?'
Luthal nods his head and starts walking up the hill towards Zook, while Kolarred remains down by the battlefield. Zook walks around a bit more, spying what he can, waiting for Luthal to get up here to take a look at things. As the gnoll approaches, both of them hear a snapping of a twig another thirty or so feet up above where Zook saw the tracks of where the kobolds fired from
((DC 15 Listen check succeeds)). The two adventurers quickly throw looks at each other to confirm that the other one heard something too, and immediately they leap behind trees and bushes to hide.
Kolarred... down below... sees both Luthal and Zok duck down behind some cover, and his inspires him to also move below some cover down below, just in case.
Zook and Luthal strain to hear anything else as they remain hidden behind their bits of cover, and while no other sounds get heard, Zook does see a flash of light as the sun reflects off a pair of eyes hidden up the hill behind a bush of their own
((Spot check succeeds)). Based on the size of the bush and the way the eyes are placed and moving about, whatever or whoever is behind it is not that large.
