🍂 Animal Kingdom Through the Seasons: Biomes, Weather and Migration

Run a full year over one landscape in three biomes and watch day length, temperature, snow and leaf colour drive bird migration, bear hibernation, the deer rut, the snowshoe hare's white winter coat and frogs thawing out. A phenology graph compares temperature, daylight and food with animal activity, and a warming slider shows how camouflage and migration timing fall out of step.
