noun: Traveling from place to place, also a course of travel, especially on foot.
From Latin peregrinari (to travel abroad), from peregrinus (foreign), from peregre (abroad), from per- (through) + ager (field, country). Ultimately from the Indo-European root agro- (field), which is also the source of agriculture, acre, peregrine, pilgrim (a variant of peregrine), and agrestic. Earliest documented use: 1475.
Banded peregrine falcons through the Midwest Peregrine Society work (midwestperegrine.umn.edu) have been documented "peregrinning" to Guatemala, Costa Rica and other countries.
