Chenopodium album
The chipping sparrow feeds on seeds year-round, although insects form most of the diet in the breeding season. Spiders are sometimes taken. "Taraxacum officinale" seeds are important during spring, and seeds from "Fallopia convolvulus", "Melilotus" spp., "Stellaria media", "Chenopodium album", "Avena" spp., and others.
