The link brings you to a YouTube video of a hawk kettle. It would have been better for the lens to be pulled back to a wider angle-- it would be a natural tendency for someone to want to 'zoom' in. But the interactions of the birds is clear. A guess would be that the swarming birds evoked an image of water boiling in a kettle.
The proper name for a group of hawks is not a flock,however it is referred to a kettle of hawks.
A group of hawks is called a cast, aerie, or kettle. the only hawk you are likely to find in groups is the Harris and it is found in Arizona and Texas. I live in Georgia and have groups of 5 or 6 hawks that circle our open pasture. Don't know what kind they are, as my camera won't zoom that far, but close enough to tell it is hawks.

A watch is a Kettle in Cockney rhyming slang: KETTLE & HOB becomes FOB WATCH. The old fashioned watch that hung on a persons waistcoat. ------------------ A watch is called a Kettle because kettles are often mistaken for watches. In order to simplify things, watch was later renamed to kettle. This watch/kettle confusion dates back 1963.
