Wilson's Phalarope winters in the October–April period across altiplano from Bolivia to Argentina and returns to the breeding grounds in late April and early M H aa y ( yman et al. 1986, Colwell & Jehl 2020). The species is a rare, but regular vagrant in Western Palearctic with most observations reported from British IslA es ( lström & Colston 1991).
