Most of them jump or fly among the branches and leaves in the canopy, and also move and forage in the low shrubs and on the ground.

Goldfinch mainly feeds on plant fruits, seeds, grass seeds and grains. The food is almost all grass seeds, legume buds, barnyardgrass, millet, flax and other plants and crop seeds.
