In the last half hour, I have learnt that terms of venery refers to words for groups of animals , many of which are listed in the Book of St Albans (1486), which is also called the Book of Hawking, Hunting and Blasing of Arms. A group of crows is referred to as a “murder of crows”. There are many more weird and amusing terms at https://en.wikipedia.org/wiki/List_of_English_terms_of_venery,_by_animal, although some of them like “a crash of rhinoceroses” have a post-1486 flavour to my mind.
I have also learnt that “venery” has two more meanings – first as a historical term for hunting game (or the hunted animal itself). An alternative and unrelated meaning is “the practice or pursuit of sexual pleasure”….(source Wikipedia).
