The article discusses how animals that provide more accurate signs of spring than the traditional Groundhog Day traditions. The article suggests that wildlife behavior, such as birds singing, frogs calling, and insects emerging as signs for spring, is more reliable than traditional predictions due to environmental cues such as longer daylight, warmer temperatures, and thawing soil rather than calendar dates. Climate change is shifting the timing of migration, breeding, and seasonal behaviors across North America, which are being influenced by shifts in daylight, temperature, and moisture. Groundhogs, also known as woodchucks, spend winter in hibernation and emerge when soil temperatures rise and soil temperatures thaw. The timing of groundhog emergence depends more on soil warmth and daylight than on whether the animal sees its shadow. Species such as spring peepers and wood frogs breed in temporary wetlands formed by snowmelt can often trigger frog choruses weeks ahead of schedule. Amphibians are often one of the most direct biological shifts of thick winter coats, making their seasonal shifts one of their seasonal changes.
