Nick now:

Obviously speculation...

I've always thought that sensing magic would essentially be Ron's 
function in the HRH horcrux killing triumvirate.  He's usually good 
with sensory things/sense of direction.  He's the one who smells the 
Troll in SS, he's the first one to hear the Durmstrang ship in GOF and 
he also is good with sense of direction (finding their way to 
Trelawney's room in POA).  Plus he's the only one who grew up in a 
wizard family, so he may have a better feel for these things than 
people who grew up with Muggles.
