There are few calls, a very old OLT one which seems to do best, a Raspy Coaxer & Pro Screamer from Primos, a button one which brought the last fox in the other night & a few homemade ones.
We usually don't get that many callouts during lambing time but this smallholding right in the middle of suburbia attracts good numbers of foxes thanks to some local residents & gets hit the worst.
bullmastiff, that is the lens cap.
