Is anyone else experiencing a large amount of passive mob spawns in their worlds?

My friend and I started a server not too long ago and I've started to notice the plains biome around us is spawning animals in huge groups. It's not really a problem since both our systems can handle it, but it is confusing, I've never seen anything like this in my solo worlds. Is anyone else experiencing this or something similar?
