Migrates from Africa to Siberia twice a year on those tiny wings. Cascading silvery song announces spring.

- Habitat
- Open, young scrubby woodland with scattered trees and dense low ground cover for nesting — birch, willow, and alder stands, damp woodland edges with bracken/moss/bramble, heath, and regenerating clearings; also parks and large gardens
- Fakta menarik
- Despite weighing only about 9 grams, the Willow Warbler is one of the longest-distance migrant songbirds relative to its size, with eastern (Siberian) populations flying up to 12,000 km each way to sub-Saharan African wintering grounds, and it is one of the few Palearctic passerines to undergo two complete body molts per year.
- Sebaran
- Breeds across the Palearctic from Ireland and Britain eastward through Scandinavia, continental Europe, and Siberia to the Anadyr River basin; occurs across over 180 countries/territories; entire population migrates to winter in sub-Saharan Africa
