What’s happening (quick recap)
- Vocal duet: Jackie and Shadow exchange chortles (soft, staccato calls) and low pair-bond notes.
- Pre-season bonding: These sessions help reinforce the pair bond and coordinate nest work (“nestoration”).
- Calm conditions: Morning light + valley quiet = unusually crisp mic pickup of their calls and tail-feather quivers.

How to listen like a pro
- Chortles vs. whistles: Chortles = short, rhythmic; contact whistles = thinner and higher.
- Body language tells: Watch tail quiver and slight head dips during Jackie’s phrases—classic emphasis cues.
- Turn it up at 3:00: You’ll catch call-and-response pacing that often precedes short work sessions at the nest.
Why it matters now
- Season ramp-up: Pair-bond and territory calls typically increase as nest work and courtship intensify.
- Expect more sticks: After vocal sessions, look for stick deliveries, rail repairs, and bowl tidying in the coming days.
- Behavior to log: Note time, weather, and who vocalizes first—useful patterns for cam-watchers.
