Celebrate the Caribbean Endemic Bird Festival (CEBF) with us! Our theme in 2025 is “Shared Spaces: Creating Bird-friendly Cities and Communities”—highlighting the crucial role bird-friendly cities and communities can have in addressing the decline in bird populations caused by threats like habitat loss, predation, and climate change. Have fun learning about a new endemic bird every day. We have colouring pages, puzzles, activities, and more. Download for free and enjoy learning about and celebrating nature!
Endemic Bird of the Day: Puerto Rican Euphonia
The Puerto Rican Euphonia is a triple threat: dazzling plumage, a melodious voice, and undeniable charm! Endemic to Puerto Rico, it’s affectionately known by locals as Canario del País or simply Eufonia. If you’re lucky, you might catch this lively little bird flitting through the canopy in places like El Yunque National Forest, Luquillo Experimental Forest, and the Carite, Maricao, and Guánica State Forests.
Adult males are striking, with a vivid orange-yellow forehead and a sky-blue cap that extends from the crown to the nape. The rest of the upperparts are a rich violet-blue, offset by a bright yellow rump and upper tail coverts. Their underparts start with a yellow throat that deepens to an orange-yellow on the breast and belly. Females, while more subdued, are equally beautiful—olive-green overall with a sky-blue cap with a sky blue helmet and yellowish forehead patch. Their yellow throats gradually deepen to a muted olive-yellow on the remaining underparts.
You’ll find these fashionable birds in a range of habitats, including mountain forests, lowland dry forests, and even shade-coffee plantations. They’ve been recorded in the Tabonuco, Palo Colorado, Palm, and Elfin (Dwarf) forests. Although usually high in the canopy, Puerto Rican Euphonias often come lower to forage along forest edges and in clearings—especially wherever mistletoe (Loranthaceae) grows, one of their favorite foods. They also snack on other small fruits like Yerba Capitana and Capulín (Muntingia calabura). Energetic and vocal, they hop busily through the trees, calling out with sharp “chit-it” notes and a cheerful “wheeee.” Their song is a rapid mix of squeaky, tinkling, and whistled notes.
Though much remains to be learned about their breeding behavior, we do know that Puerto Rican Euphonias nest year-round, with activity peaking from March to June. They build dome-shaped nests 3–20 meters above the ground, tucked into forks of branches or nestled near epiphytes. The nests are crafted from moss, lichen, and bark, bound with spider silk and lined with banana leaves and soft bark fibers. Clutch size ranges from 2 to 4 white eggs speckled with mauve or reddish-brown.
This species faces ongoing threats from deforestation, and hurricanes—bringing strong winds and tree fall—can also limit fruit availability. Supporting local environmental efforts to remove invasive species and restore native trees is key to making forests more resilient. With continued conservation, the Puerto Rican Euphonia and other forest birds can continue to thrive across the island. Learn more about this species, including its range, photos, and calls here.
