The analysis of the Kestrels' pellets likewise determines its usual food, though, as these pellets are not found in quantities together, like those of Owls, but here and there sparingly, the same amount of certainty cannot be guaranteed. Most of those that have come under my personal notice have been composed entirely of the wing-cases of all sorts of beetles and the wings of flies, and sometimes the remains of a small Vole or Mouse, but I have never discovered the remains of birds or Rabbits.
