After Having Coyotes eat the Hams off of a Deer one evening while I walked to get my truck & drive back in to it(about 20 minutes total)..I started from that day on leaving my t-shirt & Orange vest on top of my Deer when I leave it to go get my 4-wheeler or truck. I figure my smell on that t-shirt & the Orange vest keeps critters off until I get back? Never had a problem with BUzzards...but We absolutely HAVE had them kill Newborn calves. They love the afterbirth & will gather around Mama Cow & distract her while the ones at the rear do the Damage. Like a pack of Hyenas ?
