Golden Mahseer is not a bird.
– Golden Mahseer (Tor putitora) is a species of fish, found in the Himalayan region.
– Indian Nightjar (Caprimulgus indicus) is a species of bird.
– Spoonbill is the common name for birds in the subfamily Plataleinae, known for their distinct spatulate beaks.
– White Ibis is the common name for several species of birds in the genus Eudocimus, belonging to the family Threskiornithidae (ibises and spoonbills).
The question requires basic knowledge of common animal names and classification. Identifying the Golden Mahseer as a fish readily distinguishes it from the other options, which are all birds.
