AI Summary

Researchers used tiny backpacks on yellow‑rumped warblers to track their movements, revealing that these small songbirds travel in circuitous routes rather than straight paths during migration. The study focused on the warbler’s distinctive buttery yellow patch above its tail, a trait that helps identify the species in dense spruce forests. The data collected from the backpacks provide new insights into the species’ migration patterns.
