A four-day faunal survey in Kerala's Periyar Tiger Reserve documented six previously unrecorded species, including one bird, one butterfly, and four odonate species.
The new discoveries include the golden-headed cisticola, the common onyx butterfly, and four dragonfly and damselfly species.
The survey involved 75 delegates from 21 organizations and expanded the reserve's cumulative checklists to 347 bird species and 284 butterfly species.
