The Otteri Lake is situated on the North western side of the Zoological Park beyond the Birds enclosure. This lake receives the run-off water from nearly half the area of the Zoological Park. If both the monsoons are normal, water will be available throughout the year. A few years after the opening off the Zoological Park, the migratory birds started arriving at the lake. Since then the number of birds arriving to this lake has increased year after year. The bird’s census conducted on January 2011 revealed the presence of 16 species numbering 2374 birds.
