Great Horned Owls are one of the more frequently heard hooting owls. In early January, I listened to a pair of Great Horned Owls hooting at first light. I extracted the audio below from a recording of that pair. This sample is no substitute for the real thing, but it nonetheless conveys the tempo and tone of their vocalizations. The spectrogram depicts the two different owl voices – the male (lower) and female (higher).
