Actually a shade below 6 kHz, but not low enough to meet the core COFL standard.

Tick nearly reaches 4 kHz, maximum frequency nearly 7 kHz, approaching low end of PSFL range. Shape of middle note COFL-like, very similar to Warner Territory 10, but shape of final note is PSFL-like. Overall, PSFL-like intermediate.

The frequency range is intermediate. Emphasis of the tick is PSFL-like, although PSFL rarely show the middle note at all.

This intermediate note, with its long, flat, continuous middle portion, is like many from the zone of contact, which appears to stretch from central Oregon to western Montana.

This spectrogram shows an FPN just above a Song Phrase 1. Both are the right frequency for COFL: the FPN is below 7 kHz, the song phrase is below 6 kHz (a little lower than the example in the first spectrogram).
