just sitting at the base of a comfy tree for a few hrs, you'll most likely see tons of stuff, from shrews to foxes and everything in between.
once you've been still for a good while and all the animals go about their business again, its the greatest thing to watch them oblivious to you...or more likely they half know youre there, but they dont feel your a threat and let themselves be seen by you.
keep a really warm old coat in the shed or away from 'human' smells and you'll increase your chances. smoke from th efire masks them pretty well.
there's a bit of an art to sitting v still for so long, can be very painful, but its best to move once and get comfy and settle again then keep shifting with leg/back pains etc
fantastic stuff
