I'm from Germany and I always try to improve my English. Lately, I've stumbled upon a website that deals with collective nouns, that is to say, names for various groups of animals.
I always thought you'd call, for instance, many owls just "a group of owls"; however, it said they are called "a parliament". Other examples are "a litter/kindle of kittens" and "a murder of crows".
I would never doubt the trustworthiness of this website, but is it really common for "normal" English speakers (people who aren't biologists etc.) to call groups of animals like that? Would not people be puzzled if I used those terms in everyday life?
