The Koel (Eudynamys spp.) is a large, cuckoo-like bird found in the Indian subcontinent, Southeast Asia, and China. There are several species of Koels, with the most common being the Asian Koel (Eudynamys scolopacea) and the Indian Koel (Eudynamys scolopacea scolopacea).
I'm assuming you're referring to "Koel" as in the Indian bird, and "xxx" might imply a specific type of image, possibly an "xxx" rated or explicit image, but since I don't have further context, I'll provide a general reference about Koel images.
Some species of Koels are considered threatened due to habitat loss and hunting. The Asian Koel is listed as Least Concern on the IUCN Red List, but other species, such as the Indian Koel, are considered Near Threatened.
