Online timer for 70 minutes
Starting a second 70 minutes at the estuary gives you another chance to check patches missed on the first pass, but keep the method consistent so the two sets of observations remain comparable. Follow the same shoreline sections, scan exposed flats and channels, and note where godwits, oystercatchers or other birds are feeding, resting or moving as the tide changes.
Keeping the second survey running while you record birds lets you concentrate on counts and locations, yet closing the tab or browser may stop the countdown or remove it from view. If your notes depend on a clear finish time, leave the page open and keep the device awake. A separate glance at the clock can provide a useful backup without interrupting the survey.
Repeating the estuary count later in a warm New Zealand morning may produce a different picture from the first session. Rising heat can bring glare over wet sand, make distant birds harder to identify and reduce your own concentration. Use shaded viewpoints where they still cover the same survey area, carry water, and spend shorter stretches looking through binoculars before returning to wider scanning.
Common questions
What could make the second estuary survey finish earlier than the allotted window?
Heat shimmer, strong glare or a rapidly covering tide may make reliable identification impractical before the countdown ends. Record the actual stopping time and the affected shoreline sections so the shorter session is clear in your notes.
What if the bird count continues after the planned survey window?
Finish the observation already under way, then mark any later records separately. This keeps the timed dataset comparable with the first run while preserving useful sightings from the extra minutes.
