Doubleday's hummingbird (Cynanthus doubledayi) is a species of hummingbird in the family Trochilidae also known as the turquoise-crowned hummingbird. Some taxonomic authorities, such as the American Ornithological Society consider this bird to be a subspecies of the broad-billed hummingbird, while others consider it distinct.

Geographic Range

Cynanthus doubledayi is found along the Pacific coast of south-west Mexico.[3]

Diet

Hummingbirds in generally eat;[4]

  • 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.
