Safeguarding the Heart of the Cerulean Warbler’s World
The Tiny Traveler
The Remarkable Migration of the Cerulean Warbler
The Cerulean Warbler is a small, neotropical migrant that first arrives in Indiana in late April and is among the very first of our forest breeding birds to leave the state- usually in August.
Measuring a little over four inches long and weighing in at a mere eight to ten grams, the Cerulean Warbler weighs as two nickels in your pocket. Yet, these amazing birds navigate an annual migration route that takes them from their breeding grounds across the Midwest and Appalachian regions of the United States, south through Central America, and all the way to the east slope of the Andes Mountains from Venezuela to Peru for the non-breeding (winter) season.
We’re taking Action.
Indiana is home to the highest percentage of the Cerulean Warbler’s total nesting population. In March 2025, the Southern Indiana Cerulean Warbler BirdScape (SICWB) was launched as a collaborative effort with experts from more than a dozen organizations across The Americas to help protect and manage Cerulean Warbler habitats.
What to look for
The Cerulean Warbler’s Distinctive Plumage
The male cerulean is a beautiful sky-blue across the head and back, with bold white wing bars, and black wings and tail. Underneath, he is white with a dark blue “necklace” and streaks down the flanks.
The female is more aqua or sea-green in color, with a white supercilium stripe and yellowish-white underparts. It is important to note what the birds look like from underneath, as that is the most likely view you will have of them due to their affinity for staying high in the tree tops.
