The Chestnut-sided Warbler is like the cheerful muffin of the bird world, sporting bright yellow crowns and bold chestnut streaks on its sides that look like cinnamon swirls. This lively little hopper zips through bushes with endless energy, snatching insects mid-air like a tiny, feathered ninja. Its sweet, buzzy song is the perfect soundtrack for summer, making it impossible not to smile when you hear it!
