Spinks are small burrowing birds in the fifth episode of The Future is Wild series, occupying the frigid American Plains.
They are descended from quail.
Spinks feed upon tubers, and they face competition from the rattlebacks for this food source.
Once a year, the spinks emerge from their underground colonies to mate at nighttime, where the males sing and flutter their wings in an attempt to impress the females. While they're relatively safe underground, any Spink caught on the surface during the daytime becomes easy picking for the giant deathgleaners.
