api ca na vrkah sala-vrko ’nyatamo va naika-cara eka-caro va bhak-sayati.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
I do not know, but the deer might have been eaten by a wolf or a dog or by the boars that flock together or the tiger who travels alone.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Tigers never wander in the forest in flocks. Each tiger wanders alone, but forest boars keep together. Similarly, hogs, wolves and dogs also do the same. Thus Maharaja Bharata thought that the deer had been killed by some of the many ferocious animals within the forest.
