How is behaviour innate? How can animals replicate behaviour that they have never observed?

So, I know that some behaviour in animals is innate, I also understand why, but I don't understand how (except reflexes). Like, how do animals know mating rituals, or what to do when they see another animal, or how to hunt, or howl, etc.. And I know that there are instincts, but where do they come from? As in, what part of the brain, is it all subconscious? I'm sorry if I'm not explaining it well. I can't seem to find an answer on Google.

Those types of behaviors are similar to reflexes, they are “hard wired” and are initiated by an environmental cue. Often it is a series of behaviors that are initiated...an environmental cue initiated one behavior, and that behavior initiates a second behavior, and so on. Essentially, they are behavior patterns that do not need to be learned. Some texts that give a quick overview are Pierce and Cheney Behavior analysis and learning and Powell et al Learning and behavior.
