But since most of the lands are under development, the owls are fast disappearing. As the owls feed on rodents, birds, reptiles and insects and spend longer time in agricultural habitats, they are being subjected to anthropogenic activities and other interferences.u00a0</div><div><br /></div><div>Mottled wood owls, which prefer deciduous forests are found only in India and inhabit mainly forested areas, where the use of pesticides is leading to problems as they eat rodents. Also, as they are tree-hollow nesting species, they are fast losing their nesting sites because of the felling of trees in their inhabited areas.u00a0</div><div><br /></div><div>Barn owls and brown fish owls occupy more diverse habitats, with the latter preferring more water bodies and evergreen forests in their habitat. Due to the rampant destruction of rivers and lakes in Deccan Plateau, the birds have almost disappeared and have gone to upper streams as they require greener patches.u00a0</div><div><br /></div><div>"We selected an area of 1,000 m radius around the nest in order to analyse the landscape features in all of the nest territories and visited each nest at least five times. We collected pellets of digestive foods, which were scrutinised by experts from Zoological Survey of India (ZSI)," said Dr Pande.</div><div><br /></div><div>The study, besides understanding owl habitats, also included data based on Pianka Niche Overlap Index (PNOI) which suggested that spotted owlets and Indian eagle owls had maximum food overlap in terms of mammalian, avian, reptilian and insect prey, followed by barn owls and mottled wood owls, which are generalist feeders without specific food preference, while brown fish owls had the less overlap as they ate fish.u00a0</div></div><div><br /></div><div><div><b>About Dr Satish Pandey</b></div><div>DR Satish Pandey is an Interventional Vascular Radiologist and Assoc. Professor of Radiology at BJ Medical College. He works in ecology and field ornithology and has made several video films on raptor ecology, marine ecosystem and conservation, has published more than 40 papers and has authored several field guides and popular books on ornithology, nature education, orchids and other subjects to promote conservation.</div></div>
