Diet

Hummingbirds in generally eat;[3]

  • Nectar;
  • Insects;
    • Spiders
    • Larvae
    • Insect eggs.
    • Other such small insects

Insects provide critical nutrients like fat, protein and salts that nectar does not provide.

  • Sap;

Sap is consumed when nectar is unavailable and contains enough scructose to sustain the hummingbird's energy use.

  • Pollen;

Although pollen is not directly consumed an amount of pollen is stuck to the Hummingbird's beak thus being ingested, only about 10% of ingested pollen is actually digested and provides a small amount of protein.
