Kaggaladu, Bird sanctuary in Sira Taluk, Karnataka, India.

Kaggaladu is a village in Sira Taluk, Tumkur district, Karnataka, where tamarind trees serve as a heronry for painted storks and grey herons. The birds nest in the trees from February to August, and the village has been recognized as a bird sanctuary since 1999.

Grey herons nested on a single tamarind tree in Kaggaladu from 1993, according to villagers. Their numbers grew in 1996 after poachers disturbed a nesting tree at neighbouring Muddenahalli and killed some birds. In 1999 the Tumkur-based NGO Wildlife Aware Nature Club brought the heronry to outside attention, and the site is described as South India's second-largest painted stork sanctuary after Kokrebellur in Mandya district.

The village community views the tamarind trees as shared space where birds thrive, and sees nesting activity as a sign of good land health. This relationship between people and birds shapes how the area is valued and protected each season.

Kaggaladu lies 9 km northwest of Sira on the Sira-Changavara Main Road; Sira is about 120 km from Bangalore by road and 50 km from Tumkur, the district headquarters and nearest railway station, with Bangalore the nearest airport. The birds arrive in groups from late December or the first week of January, sometimes as late as March, and leave by the end of August. The nesting trees stand within the village itself, so visitors walk among them on foot.

Villagers do not harvest tamarind from trees they own or from government-owned trees, leaving the pods for the nesting birds. Some residents protect the herons because they see them as harbingers of prosperity. The heronry was first reported to the outside world in 1999 by the Tumkur-based NGO Wildlife Aware Nature Club.
