Hornbills select nest sites based on the availability and type of fruiting trees, as well as on the availability and quality of nest site cavities in their particular habitat. Some oriental pied hornbills have demonstrated tree species preferences for nest site selection. In Rajaji National Park in India, oriental pied hornbills nest in a variety of tree species such as "Bombax ceiba", "Careya arborea", "Cordia myxa", "Lagerstroemia parviflora", "Mitragyma parviflora", "Terminalia belerica", "Shorea robusta", and "Syzigium cumini".
