Cerulean Warbler

*Top 50 Target Species (Seen, but never photographed)

In Ecuador, the Cerulean Warbler is an uncommon but regular boreal migrant, wintering in humid montane forests on the eastern Andean slopes, typically between 800 and 2,000 meters. This small, sky-blue songbird favors mature forest canopy and often joins mixed-species flocks, gleaning insects from leaves and twigs with agile, acrobatic movements. Its global population has declined sharply due to breeding habitat loss in North America and deforestation in its Andean wintering grounds, prompting its IUCN listing as Vulnerable. Conservation efforts in Ecuador, including habitat monitoring near Sumaco Napo–Galeras National Park, aim to protect key wintering sites and raise local awareness of this migratory jewel.
