The term "shite-hawk" is believed to have originated as military slang by the British Army in India and Egypt, as a derogatory term for the black kite (Milvus migrans), which was despised by soldiers for its habit of stealing food from their plates:[2][3] At the transit camp the British soldier normally made his acquaintance with the kite-hawk [i.e. black kite], known familiarly as the 'shite-hawk'. 'There used to be thousands of them,' remembers Charles Wright. 'When one drew one's food from the cook-house and went to take it across to the dining room to eat at the tables underneath the sheds, these kite-hawks would swoop down and take the lot off your plate if you weren't careful. So you had to walk waving your arms above the plate until you got it under cover.' — Charles Allen, Plain Tales from the Raj[4] Probably a shite-hawk.
Actually hawks do not eat dead rotting prey like vultures. Hawks actively capture fresh prey on their own and devour it.
Was about to post this but glad someone did. I don't expect facts will dissuade him, but kudos to you for trying.
Hawks will eat carrion, most raptors will if hungry. https://www.hawk-conservancy.org/wp-content/uploads/2016/11/IMG_9771.jpg https://en.wikipedia.org/wiki/Anterior_cingulate_cortex This is the bit of your brain that does not work so well.
