Can you name all 18 species of Penguins? Don't be dissapointed if you can't because I probably couldn't either.
Birds Species by Family series : https://www.jetpunk.com/series/1263160/bird-species-by-family
Note 2: these 18 species are the ones listed on eBird. Wikipedia and the book that I was using gave conflicting information on what is a species or a subspecies.
You don't need to type penguin every time, just the first part of it's name
