A guided walk-through. Site, conditions, observations, sign-off.
DuskWatch sessions are run by Stewards in the For Shorebirds cohort. Sign in with the cohort password and your initials.
Filled at session start, when you arrive at the observation point.
Pull from BoM Caloundra Aero or Brisbane Aero on a phone before the session. Three readings: now, 6 hours ago, 24 hours ago. Trends are computed automatically. Tests whether Terek arrival at KBR is anticipatory (birds reading a falling barometer ahead of foul weather) or reactive (shift only after the wind is up).
Add a row for every flock event during the session window. Times are stamped automatically — adjust if the event happened earlier than the moment you logged it.
Net arrivals by species per 30-minute block, estimated from flock-size midpoints. This is the input row for the Sanders/Handmaker analysis.
Three timed scans of the settled Terek flock — at sunset, at civil twilight, and at civil twilight +30 min where light permits. Estimate the percentage of the focal flock in each posture. Percentages should sum to 100 within each scan.
If the scope shows individually marked birds in the settled flock, log them here. Resightings of Australian-flagged Tereks (and any flyway flag combination) feed BirdMark, the EAAF colour-marked wader database. Branson et al. 2010 (Wader Study Group Bulletin 117: 27–34) is the foundational Terek-flag reference for the flyway. Eastern Australian Tereks have a distinct migration pattern from the better-studied Roebuck Bay cohort.
A new row for every disturbance event during the session — distance estimated to the nearest 25 m against landmarks; resettle time from flight to settled, with destination if the flock relocated.
Final check before queuing. Submitted records are held on this device and sync when the endpoint next responds.
