Do organisms only migrate during the winter season?

No, organisms do not only migrate during the winter season. While many species, particularly birds, migrate south to warmer climates during winter to escape harsh conditions and find food, others may migrate during different seasons for breeding, feeding, or avoiding extreme temperatures. For instance, some species may migrate in spring to reach breeding grounds or in response to seasonal changes in food availability. Migration patterns vary widely among species based on their ecological needs and environmental cues.
