This video about a parakeet nest in India says about itself:
18 April 2015
The rose-ringed parakeet (Psittacula krameri), also known as the ring-necked parakeet, is a gregarious tropical Afro-Asian parakeet species that has an extremely large range.The rose-ringed parakeet is sexually dimorphic. The adult male sports a red or black neck-ring and the hen and immature birds of both sexes either show no neck rings, or display shadow-like pale to dark grey neck rings.
This parrot species now also lives outside its original African and Asian homeland.
I have quite often seen ring-necked parakeets outside my window: one, two or three birds. However, today was special with a flock of ten parakeets. Nine in one tree, one ring-necked parakeet in the next tree. I had never seen so many of them there.
