Wolf excrement with wild boar: Unmistakable. Wild boar is a common prey in the Sierra de la Culebra, though it is unlikely wolves tackle full-grown male boars. Note the dark black excrement underneath. A wolf has marked its presence directly on top of a fox’s excrement. A reminder of who is the boss.
Wolf pawprint next to varied wild boar tracks. Note the pronounces claw marks. The claws of dogs (or at least domestic ones) are blunter as they are warn down these days by tarmasc. Tracking formed an important part of the trip.
Wolf excrement with red deer or roe deer. Commonest form of prey in the Sierra. There are some 1,200 red deer and 500 roe deer in the reserve. Each of the six or seven packs need a medium–sized red deer a week to survive, though as can be seen here their diet is varied. Count on an average of a kilo/day per wolf.
Wolf excrement with sheep. As noted here though a common prey in parts of Spain, wolves here in the Sierra eat very few sheep
A badger’s pawprint
And nearby two badger’s claws (I think) found in a wolf excrement. Badger is not a common prey for wolves as it will fight to the end and there are few citations in the Spanish literature. Maybe it was carrion.
