A "Snowbird" Defined
The term Snowbird is used to describe people from the Northeast, Midwestern United States, or Canada who spend a large portion of winter in warmer locales such as Florida. Residents of northern Europe also flock to the warmer areas like Florida establishing second communities of seasonal residents.
Snowbirds are typically retirees, and business owners who can afford to be away from home for long periods of time or have a second home in a warmer location like Florida. Some snowbirds carry their homes with them, such as RV's and Watercrafters follow the east coast Intracoastal waterway.
It used to be that snowbirds were the wealthy who maintained several seasonal residences and shifted residence with the seasons to avail themselves of the best time to be at each location.
Many of these "Snowbirds" also use their vacation time to declare permanent residency in low, or no tax states (where the taxes are sustained by high tourism taxes), and claim lower non-resident income taxes in their home states. Some are reputed to use this dual-residency to absentee vote in both locales.
