peregrine
Pronunciation: /ˈpɛrɪgrɪn/
noun

Origin:
late Middle English: from Latin peregrinus 'foreign', from peregre 'abroad', from per- 'through' + ager 'field'. The falcon's name is a translation of the modern Latin taxonomic name, literally 'pilgrim falcon', because falconers' birds were caught fully grown on migration, not taken from the nest
