Kokkarebellur Bird Sanctuary, usually shortened by the colloquial usage to Kokrebellur is a village in Maddur taluk of Mandya district of Karnataka, India.

During the season of migration of birds, large colonies of spot-billed pelicans and painted storks are seen nesting, mostly in tamarind trees.

In 1976, Neginhal established viable solutions by introducing a compensatory scheme to benefit the villagers for furthering the cause of proliferation of this breed of pelicans.

Village women turning sentimental about the birds returning to their homeland say:[4] For us, these birds are like a daughter coming home for delivery....The main species that nest in Kokkarebellur – the spot-billed pelican (Pelecanus phillipensis) and painted stork (Ibis leucocephalus) are given the conservation status of "near threatened category" in the IUCN Red List of 2008.

The pelicans have grey and grayish white plumage, short stout legs, large webbed feet, flat and enormous bill with an elastic bag of purple skin hanging below the throat (that facilitates to collect fish from water surfaces), with length or height in the range of 127–140 centimetres (50–55 in) with tufted crown at the back of the head and lay a maximum of three chalk white eggs at a time.

The spot-billed pelicans are protected by law in India and also in several other countries of the region (Sri Lanka, China, Myanmar, Thailand, Cambodia and Laos) to avert threats in the form of tree felling for agricultural purposes.

The list of planned activities involved cover the following:[1] ‘Hejjarle Balaga’(ಹೆಜ್ಜಾರ್ಲೆ ಬಳಗ)(meaning "relatives of pelican") of the Mysore Amateur Naturalists (MAN), an NGO, works in unison with the villagers in providing protection to these birds.

The villagers with support from volunteers of the NGOs tend to the injured hatchlings/fledglings that fall from the trees by housing them in exclusively built pens, nurse and feed them with fish caught from nearby water bodies.

The branch road to the village is 12 kilometres (7.5 mi) from the highway at the ‘Coffee day’ landmark, close to Maddur.
