A load of micro UAVs with chemical sensors covering a large area at low level assuming you can successfully avoid branches might be more practical.
If a single uav detects a candidate scent the others nearby could swarm to confirm and perhaps give a better idea of corpse size.
Maybe just send them round looking for concentrations of flies?
