Insects
Small insects, larvae, insect eggs, and spiders are critical food sources for hummingbirds.
Sap
Whennectar is scarce, hummingbirds will sip tree sap from wells drilled by woodpeckers.
Ashes and Sand
Some hummingbirds have been observed eating ashes and sand in small quantities.
More close observation and study are needed to determine how critical this food source may be for hummingbirds.
Fruit
Certain ripe or juicy fruits may attract hummingbirds.
