I have always found collective animal names fascinating, and always try to learn as many of them as possible. Over the years I have collected the ones that I've been able to confirm. Here, on this website, you will find a fairly large collection of collective animal names. Even though this list is by no means complete, it can get you started on your way to learning all of the animal collectives.
Simply select the first letter of the animal's name to which you would like to find out the collective name to. You will then see a list of animal names and their respctive name collectives. You can also use the search box at the top of the page to search for a specific animal name or a collective.
Additionally we have a small collection of male and female animal names, as well as baby animal names.
