Paisley born Alexander Wilson emigrated to America in 1794. Reinventing himself as a pioneering naturalist he was the first person to attempt to document all the birds of North America.
In 1810 he watched in awe as a single flock of passenger pigeons took four hours to pass overhead and estimated the flock to contain over 2.2 billion birds.
Yet in just over 100 years, this, the most abundant bird in North America was gone forever as Martha the world’s last known survivor died on 1 September 1914 in Cincinnati Zoo.��
