Seven peacocks were found lying dead on the banks of a river on the outskirts of Samadhiyala village in Khambha taluka on Saturday.
Preliminary investigation of the forest department pointed towards food poisoning as the cause of death of the birds.
"As no injury marks were found, food poisoning is suspected. However, nothing can be ascertained till the post-mortem is conducted," said deputy forest officer of Dhari east range.
It may be recalled that a large number of peacock feathers were found from a farmhouse near Samadhiyala village, giving rise to the suspicion of peacock hunting in the area. However, the forest department's investigation of Saturday's incident did not yield any links to poaching.
