Eurasian woodcock
A four-day survey was conducted on 1–4 December 2016, organised under the aegis of the Periyar Tiger Reserve (PTR) and found the presence of 13 new bird and 16 butterfly species that were undetected earlier. The newly found bird species included Eurasian woodcock ("Scolopax rusticola"), steppe gull ("Larus fuscus barbensis"), grey-necked bunting ("Emberiza bruniceps") and paddyfield warbler ("Acrocephalus agricola").
