I remember seeing Masked Lapwings (Spur-winged Plover, Vanillas miles) in Marlborough when on family holidays as a child. They self-introduced to the lower South Island of Aotearoa New Zealand from Australia in the 1930s and from the 1960s began a rapid spread.

They are now a common sight and sound around most of the country. This pair were resting on the mudflats at Motukaraka Point. Curiously, they each hopped away on one leg until out of the rockier area, whereupon they began walking normally.
