Show Notes

Yellow-eyed Juncos sometimes make a migration of sorts — not from north to south, but from the high mountains to the lowlands or the other way around. It’s called altitudinal migration. In the warm summer months, some Yellow-eyed Juncos prefer to nest at higher elevations. In winter, however, the scarcity of food pushes them back down to the valleys.
