What's That Racket?

The gulls started squawking at 1:30 this morning. I could tell they were very agitated about something so I unzipped my tent to look out (light all night). I saw a smallish 4-legged critter scurrying around the edge of camp and the gulls were buzzing it. I got out of my tent to get a better look and Ramona got up too. It was a mottled gray-white fox with a white-tipped tail. Ramona said it was in the 'red fox' family, but this mottled type was called a 'cross-fox'.
