The VWSG, made up of 140 volunteers, has contributed to monitoring of waders in Victoria and SE Australia for 40 years. We have a number of important monitoring around Melb, including Port Philip & Western Port Bay #SCBMelb21
2/5
Through long-term capture/banding/flagging in Vic, starting in 1974, our data have contributed to measuring population decline of waders across the East Asian Aus Flyway. REF: nature.com/articles/ncomm…
Note diff ⬇️trajectories in Curlew Sandpiper & Red-necked Stint. #SCBMelb21
3/5
These waders which we captured in Australia migrate to the Arctic to breed, annually.
Through fitting of geos on birds in Western Port Bay we find that Red-necked Stint (blue) and Curlew Sandpiper (orange) have similar migration routes, but different strategies #SCBMelb21
4/5
Curlew Sandpiper use fewer stop-over sites along migration, with more reliance on Yellow Sea than Red-necked Stint.
This "minor" difference may be driving differences in trajectories of ⬇️ population decline
Useful data for conservation strategies along EAAF #SCBMelb21 Image
5/5
Through data collected by our local heros, we can have a global impact for waders!

1/6 140 VWSG volunteers have been monitoring waders in SE Aus for 40 years. We have several important sites around Victoria, Tas & S. Australia for catching and banding waders. Data are used for pop monitoring, migration route, survival and repro rate assessment

2/6 Using geolocators we have revealed the AMAZING migration of Ruddy Turnstones. Flagging shows individuals return to exactly the same stretch of beach on King Island each summer. Adult birds migrate ~12,500km to Siberia to breed before returning
#ISTC20 #Sesh8
3/6 Curlew Sandpipers are experiencing drastic population declines. Through tracking, we find that they leave earlier, use fewer sites, are more site specific, and arrive later than Red-necked Stint, which has only minor population declines. #ISTC20 #Sesh8
