The checklist of birds at the Nanjarayan tank Bird Sanctuary in Tiruppur touched 187 when a Forest Department watcher spotted a Pied Avocet (Recurvirostra avosetta), a shore bird, on Tuesday.
Experts said the sighting of the bird in the sanctuary is significant as it is a vagrant that is rarely spotted in inland water bodies.
According to the Nature Society of Tiruppur, the Forest Department watcher Sivamani sighted the bird on Tuesday morning and shared the photo of the uncommon bird with members of the society.
