Short-tailed weasels change colors with the seasons.

• A. False
• B. They only change color in winter
• C. They change color every month
• D. True

Answer: (D)

Seasonal molt drives color change in short-tailed weasels. In many populations, they shed their summer brown coat and grow a white winter coat (ermine) to blend with snow, then molt back to brown as snow disappears. This cycle is tied to changing daylight and hormonal signals, not a monthly pattern. While the typical pattern is seasonal, some individuals in milder climates may not whiten as much or at all, but the overall behavior is a seasonal color change. So the statement is true because the species commonly changes fur color with the seasons to match its environment.
