Anton has been studying the ecology of migrant waders on the steppe lakes of European Russia (the Republic of Kalmykia, the Volgograd and Astrakhan Regions) since 2001. He is interested in interspecific relationships, competition and ecological segregation of closely related species of waders. Anton met Prof. Tamas Székely in 2003 at the International Wader Study Group conference in Cadiz (Spain) and became interested in breeding biology of Kentish plover (Charadrius alexandrinus).

Since 2006 Anton has studied this species at the Elton Lake in Russia – one of the largest salt lakes in Europe (surface area of this lake is about 150 km2). In 2012 he also took part in the expedition on Sakhalin Island (Far East of Russia), where we were studying migration of Spoon-billed sandpiper Calidris pygmaea and other waders. In 2017-2018 he took part in expeditions to the Kamchatka Peninsula, where he and his team studied the ecology of migrating waders (primarily colour marking Great Knot (Calidris tenuirostris) at one of the important stopover sites on the East Asian-Australasian Flyway.
