Online timer for 1 hour
Start a 1 hour countdown, put your phone away, and spend the interval gathering bird observations across the estuary. You can watch the mudflats, channels, and shoreline without repeatedly checking the screen, then return when the alert marks the end of a consistent survey window.
Back at the estuary after the alert, save the observations and begin another countdown if more coverage is needed. Several consecutive windows can separate changes in bird numbers or behaviour as the tide moves, while keeping each set of notes comparable. A short pause between them leaves time to record the location, weather, and direction of travel before attention returns to the birds.
A quiet mudflat may need the full window, whereas a busy roost or a rapidly advancing tide can make a shorter survey more practical. Let visibility, access, bird activity, and the size of the area determine the interval. If the chosen window regularly ends before the shoreline section is covered, narrow the survey area or allow longer next time rather than rushing the final observations.
Common questions
What could make this estuary bird survey window shorter?
An incoming tide that covers the feeding area, strong wind, glare, or birds moving beyond a safe viewing point can end the survey early. Save the notes with the actual finishing time so the shorter observation period remains clear.
What if one estuary section takes longer than the chosen window?
Finish the current observation without hurrying, then note the extra time separately. For the next survey, use consecutive windows or reduce the stretch of shoreline being covered.
