Columba livia or blue rock pigeon is easily available and plenty in numbers everywhere. It's body is big in size than many other bird species. The study was carried out in Jodhpur, both in urban and rural/sub urban areas in the year 2023. For the study road side survey and interviewing people to know the recent population of Columba livia and other birds, religious and mythological aspects etc. The result shows that people are much more religious and bird feeding was seen nearly in each society, there is a space bird feeding so called "Kabutaron ka Chabutara". Artificial bird houses are also built in rural areas, mostly residing by Columba. Mythological aspects also help to increase population size. Columba population is an indirect danger for other birds, as its big size keeps the other birds away from the feeding, nesting sites, bird houses. Thus indirectly it creates adverse effect on population of other avian fauna nearby.
