American goldfinch eating giant ragweed (Ambrosia trifida) seeds at Chimney Rock Park IA 2K3A3488

I often see black-capped chickadees enjoying the nutritious giant ragweed seeds and today I found a flock of American goldfinches feeding on them. Many people hate giant ragweed and eradicate the plants on sight since its pollen does cause hay fever in the fall - but that's a shame since giant ragweed seeds are so beneficial to local songbirds as they prepare for a long hard winter ahead.
