This is bird note.

These thin silver recalls coming from the forest belong to a survivor, the golden-crowned kinglet.

This bird weighs six grams, about the same as two pennies,

yet they winter as far north as Alaska and Nova Scotia.

With short days, intense cold and heavy snow,

how do Kinglets stay alive?

Biologist Bernd Heinrich found that the kinglets moved through the forest in small flocks and feed constantly at almost one peck per second throughout the short day.

By doing this, they take in enough tiny per second throughout the short day.

By doing this, they take in enough tiny caterpillars to maintain their internal furnace at

110 degrees Fahrenheit. And their insulation keeps them warm.

Their feathers make up 8% of their body weight,

equivalent to the weight of the clothing of an Arctic explorer.

When night falls, the flock huddles together to conserve heat, another of their superb adaptations

for survival. for
