Observation details
Vocals best match McCall’s rather than Northern. I posted this list to the Facebook Advanced Bird ID page to confirm subspecies. The reply that helps most from Nathan Pieplow: I agree with McCall's... the key distinctions on the spectrogram are the nearly flat shape of the tremolo calls, with the highest bump right near the beginning, and the vaguely two-parted quality of the trill call. There is also a consensus between the current owl literature and other birders is that this should be the expected subspecies in the southern parts of the county
