Birds and bugs drop

So far in Minecraft (not including Dungeons and Legends), there are only two birds (chickens and parrots), two insects (bees and silverfish), and three arachnids (spiders, cave spiders, and endermites [I looked this up, and mites are technically arachnids]), which means that we need a "birds and bugs" drop that can add some new mobs. It can add some of the things that are present in the other games, like hawks and toucans (Dungeons); and butterflies and dragonflies (Legends).
