Behaviour
Chestnut-sided warblers forage in shrubs and hold their tails cocked.
Why they matter
Chestnut-sided warblers were rare when eastern forests were intact and increased as clearings grew back. They depend on young, shrubby forest.

Eggs — Usually four
Incubation — About 11 to 12 days
Chicks — Fed by both parents
Lifespan — Several years
Living around people
- Young forest clearings support them.
Misconceptions
