- Abstract
Spatial and temporal variation in shorebird use of tidal flat feeding habitats has been subject to limited monitoring, including in Moreton Bay, one of the most important shorebird areas in Australia. We present the results of 12 years of monitoring over a 17-year period (2004 to 2021) of shorebird use of an extensive and important area of tidal flats on the mainland shoreline of Moreton Bay at Brisbane Airport. The overall migratory shorebird population increased from September to peak in November and declined thereafter. The maximum count of migratory shorebirds feeding on the 96.5 ha of tidal flats each year ranged between 1,340 and 2,546. There was no significant trend in the average total count for any migratory shorebird species during the austral summer months (October to February) over the 11-year period 2009/10 to 2020/21 besides Pacific Golden Plover Pluvialis fulva, which showed a significant increase in average abundance. The relative importance of the Brisbane Airport foreshore tidal flats to a species' Moreton Bay population was greatest for Curlew Sandpiper Calidris ferruginea, supporting 16% of the Moreton Bay population on average but up to a maximum of 43%. While the Brisbane Airport tidal flats comprise just 1% of the tidal flat area in Moreton Bay, they support approximately 3.8% to 7.3% of the estimated total Moreton Bay population of migratory shorebirds.
