Birds aren't the only animals that migrate North and South through North America. During the Spring, the
Monarch butterfly heads North, reaching their Northern-most destination over 3 or 4 generations. The final generation makes the return trip to their overwintering location in a single generation. Unfortunately, Monarch populations are
declining precipitously. The World Wildlife Fund reports a 59% decline just this year. Read about what you can do to help
here.
