New insights from geolocators deployed on waders in Australia
Geolocators were deployed on waders in Australia for a third successive year, in Feb/Apr 2011 including on Eastern Curlew and Sanderling for the first time. Retrieval rates, in the 2011/12 austral summer, varied markedly between species. Technical performance of the geolocators was better than in pr...

Geolocators were deployed on waders in Australia for a third successive year, in Feb/Apr 2011 including on Eastern Curlew and Sanderling for the first time. Retrieval rates, in the 2011/12 austral summer, varied markedly between species. Technical performance of the geolocators was better than in previous years. However units on Greater Sand Plovers, migrating to breeding grounds in the Gobi Desert, China/Mongolia, again behaved erratically, and exhibited symptoms suggesting extraneous electromagnetic interference. Generally, for each species studied, the results confirm earlier indications that the first step of northward migration from Australia is a long non-stop flight. Subsequent movements to breeding areas are usually shorter with up to three stopovers in SE Asia or Siberia. Similarly southward migration strategies include at least one long nonstop flight, though this is usually the second (or later) leg of the journey. The timing of migration appears to be particularly related to breeding latitude. Eastern Curlews, which breed at relatively southern latitudes, depart from SE Australia from early March, reach the breeding grounds and lay eggs in April, set off on return migration in early June and, after a long stopover in the Yellow Sea, arrive back in SE Australia in early August.
