Mr. Sibley, who puts the goldfinch on his cover, tells us they're sociable birds who like to hang with each other. This may explain why I had two in the echinacea yesterday and have three there right now plus six in the dogwood. Including a mother and her two chicks, who're demanding to be fed. These are such small birds that to see the chicks flapping their tiny wings and opening their miniature beaks is like watching dollhouse toys come to life.
