A group of Magpies is most often called a ‘tiding’, though several other collective nouns are used too: a ‘mischief’, a ‘conventicle’, a ‘congregation’, a ‘charm’, a ‘tribe’, a ‘gulp’, and a ‘tittering’. The word ‘tiding’ is widely thought to trace back to the Old English ‘tidan’, meaning ‘to make a noise’. That link makes sense given how loud and distinctive a Magpie’s call is, especially when the birds gather in numbers.
