The weather in the Caribbean may seem like summer year-round, but the tropical heat doesn’t mean there are no seasons. Like most tropical areas, rainfall is a primary differentiator for Caribbean seasons, and rainfall drives changes in vegetation as well as wildlife populations. While many animals can, and do, breed year-round in this area, reproductive rates can increase dramatically when rainy weather boosts the amount of food available. Clouds of butterflies in the winter are a noticeable example, but many other species are going through a population boom more quietly right now.
