The Common Sandpiper is a small species of sandpiper with plain brown and white plumage and greenish-grey legs. A rare visitor to Brisbane, almost all records are of solitary birds. The species prefers the muddy banks of waterways, but also occasionally visits traditional wetlands and swamps, mudflats and grasslands.
A shy species of muddy riverbanks and verges, the Common Sandpiper, despite its name, is anything but common in the Brisbane region. A migratory species like most other Calidrids, the birds breed in the Palaearctic over the Boreal summer before migrating south to their wintering grounds in Africa, Asia and Australasia.
Within the Brisbane LGA, Common Sandpipers have only occurred at a handful of locations, almost exclusively in the eastern half of the region, although the odd bird does turn up in the Lockyer Valley inland, so it is likely birds may visit suitable habitat in western Brisbane too. While superficially similar to certain other shorebirds, Common Sandpipers have a very distinctive feeding behaviour, with birds dashing from spot to spot, bobbing their head and tail while pausing to feed. The species has never occurred in large numbers in Brisbane (unlike many other shorebird species), with a high count of just 4 birds at once (Wright 2018), and only a handful of multiples.
Birds have only been recorded in Brisbane in the warmer months from September to March, although it is possible that some (particularly younger or non-breeding) birds may overwinter. As a species dependent on suitable muddy riparian habitat, Common Sandpipers are somewhat threatened by habitat destruction in Brisbane and more broadly across their range, although they do not appear to be as threatened as many other shorebird species thanks to their decreased reliance on large mudflats and their versatility in adapting to less ideal habitats.
Note: the astute Atlasser would be aware that there are a handful of other sandpiper species that share ID similarities with Common Sandpipers. The most likely of these species in Brisbane is the [Wood Sandpiper], which probably turns up most years but, like this species, is underreported. Other species, such as the Green, Solitary and Spotted Sandpipers, share a number of features with the Common Sandpiper, but all of these constitute nationally significant rarities and are highly unlikely to occur. It pays to check though!
Distribution and Habitat
Common Sandpipers are broadly distributed across much of the world, although within Australia they are more patchy, occurring mostly around the coastline with a few records further inland. They are quite rare in South East Queensland, and within Brisbane have almost exclusively been recorded on the eastern shores of the city, with the westernmost record being a single bird at Oxley Creek Common in 2013 (Wunsch 2013). It is probable that the odd bird visits suitable habitat in the western suburbs, especially given birds occur farther west in the Lockyer Valley, although given the paucity of data recorded from this area and the comparatively poorer shorebird habitat present it is not surprising that there are no records to date.
The distribution of birds within Brisbane shows a clear seasonal trend, with the species only being present over the summer months, as would be expected given their migratory behaviour. There are no records of overwintering birds, although if birds were to stay year-round it is plausible they would remain in the same locations and not move between sites within the LGA without external pressures.
Seasonality and Breeding
Common Sandpipers have never been reported breeding in Brisbane, which is unsurprising given they are long-distance migrants and almost exclusively breed at high latitudes in the northern hemisphere. The peak in this species’ reporting rate, both in Australia and in Brisbane, coincides with the Austral summer / Boreal winter, as birds leave the breeding grounds to avoid the harsh winter weather, wintering in the temperate Brisbane (and more broadly subtropical or tropical) climate before returning to the Palaearctic to breed.
Trends
Given this species’ rarity in Brisbane, there are no clear trends apparent within the data to suggest whether this species is declining, stable or increasing locally. Given that the worldwide population is quite stable, although with some small declines, the population is probably stable within Brisbane, although with local habitat changes this may change. More data is needed to verify this either way.
Information Gaps
- Determine whether this species is underreported
- Collect more data for this species
- Identify the flight paths and breeding sites of Brisbane birds to aid in conservation
Key Conservation Needs
- Protect key habitat all along the flyway, from Brisbane to Lapland
