John C. Dvorak shares a recording of a mockingbird that sits on his chimney and uses it as a resonance chamber to amplify its calls into his house. Dvorak placed an H2 recorder in his firebox to capture the sound, which he describes as a form of "MKUltra" psychological warfare due to its volume and lack of musical talent. The hosts joke about the bird's ability to mimic car alarms and rainbird sprinklers.
