Autumn Equinox Natural Wonders
Monarch Butterflies Migrate South to Wintering Grounds in Mexico
The cooler and shorter days of autumn trigger changes that cause monarchs to migrate south. They develop reserves of body fat that are used to fuel their migration of 1000-3000 miles to Mexico. Along the way they must refuel with nectar sources. Goldenrod plant flowering coincides with the time of migration and is a critical energy source for them.
These videos were taken on Fire Island in the beginning of October, and give testimony to how many monarchs make this amazing migration in the Fall, and how Long Island is an important step along their journey. Every thing that flies by is a monarch!
Hawks, falcons, osprey, and other birds of prey give a great show as they migrate over Long Island in the autumn. Best places to see them are on the south shore beaches. They fly around with the speed and detemination of a jet-fighter pilot!
