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.
