During the year 1999, a few members belonging to Wildlife Aware Nature Club, which is an NGO located in Tumkur had spread awareness about this wildlife sanctuary. Thereafter, people came to imbibe knowledge about the existence of Kaggaladu Bird Sanctuary. The regional inhabitants of Tumkur have asserted that Grey Herons have been building their refuge here ever since 1993. Some of the local residents made attempts to preserve these birds as they were impressed by their charm, while several others are of the opinion that such birds are messengers of prosperity and harmony. These people are so dedicated towards the species that they have stopped cultivating and harvesting tamarind inside the park. Some of these trees are privately owned while some had been donated by the state Government. The herons stay at Kaggaladu Heronry for around six months. They arrive here in February and stay till August. By the end of the month they migrate to another place. Within this time span they build nests, lay eggs and rear young ones.
Herds of blackbuck and the Great Indian Bustard are also said to wander in this sanctuary, according to the accounts of some villagers. Numerable foreign migratory birds are also found in the Kaggaladu Heronry Wildlife Sanctuary. In this bird sanctuary, one can find the birds in hundreds of number, but the big gathering of birds is not of the same feather. The tamarind trees have been maintained exclusively for birds shelter and nestling. It has been reported that, the villagers of Kaggaladu are very much attached to these migrating birds.
Kaggaladu Bird Sanctuary is also known to be the world's second largest sanctuary for painted storks, particularly in southern India. Several species of foreign birds also flock to this sanctuary. Kaggaladu Bird Sanctuary in Karnataka, thus, has also become a popular tourist destination. From Sira district the forest reserve is accessible from Sira and Tumkur by road.
