I had a Lesser Goldfinch doing a Western Wood-Pewee call in my backyard in Stanislaus County a couple weeks ago. I wondered if it might have heard an early migrant or if it just remembered the call from a previous season. Does anyone know if there has ever been a study of how long goldfinches, or even mockingbirds, for that matter, retain songs/calls they’ve learned to mimic?
