250 Dollars - Elizabeth II Great Bustard

The great bustard (Otis tarda) was extinct in Britain by the 1840s, hunted out over roughly three centuries of agricultural enclosure and unrestricted shooting. A reintroduction program on Salisbury Plain, begun in 2004 using birds sourced from Russia, has established a small but breeding population — the species' first wild reproduction in the UK in over 170 years. Niue's wildlife coinage series has leaned heavily on endangered and recovering species, issued under a licensing arrangement that has made the island one of the more prolific bullion program issuers despite having no meaningful domestic precious metals industry.
