A few words which explains the title? Love the frame however!

Hello Ganesh Sir...
First of all sorry for late reply...
The group of Crows is known as Murder.
There are many reasons behind using this term mostly based on stories & also because Crows are scavengers, so it is believed that the presence of Crows is an Omen of Death...
This is how they got the name for there flock - MURDER...
Here it is my attempt to portray the Murder in concrete jungle...

And thanks for appreciation Sir...
