Birds of Puerto Rico: Although less than 3,500 square miles in size, the island of Puerto Rico punches above its weight regarding avian biodiversity. This Caribbean Island is home to over 350 bird species – both migrants visiting on their seasonal travels as well as year-round residents.
Most uniquely, Puerto Rico hosts 17 endemic bird species found nowhere else on the planet along with several non-endemic birds too. These birds likely evolved from ancestors that colonized the island millions of years ago. Over time, they diverged into separate species adapted to Puerto Rico’s varied ecosystems like lush rainforests, mangrove forests, cloud forests high in the mountains, and dry forests along the coasts.
The high level of endemism makes the birds of Puerto Rico of immense conservation value. Sadly, over half of the endemic species are now endangered as they grapple with threats like habitat loss and introduced predators. Protecting these avian gems is crucial.
This page gives an overview of the secretive endemic birds that call La Isla del Encanto – the Enchanted Island – their home. Each species has developed unique traits and behaviors to carve out a living in Puerto Rico’s forests, wetlands, and scrublands. Getting a glimpse of even one of these special birds in the wild is a magical experience.

Understand this diminutive species' undisrupted pathway reliance on habitat connectivity to counter migration needs.
Follow the extraordinary story of the Puerto Rican Amazon. Once abundant across mountain forests, this vivid parrot now relies on dedicated conservation to defy extinction odds. Learn about its distinctive red-crowned green plumage, role dispersing seeds, the intensive recovery effort when just 13 birds remained in 1975, and why protecting precious habitat remains key to overcoming threats for this critically endangered species.
Preview a striking rainforest specialist, the ebony Puerto Rican Bullfinch (Melopyrrha portoricensis) accentuated by bright splashes of orange, whose adaptation across wooded uplands can't safeguard its uncertain future outlook. Learn why targeted conservation pairing habitat protections with agricultural supports provides the integrated strategy needed to sustain this vivid and versatile island forager.
Follow a tiny metallic-hued hovercraft nimbly navigating the maze of mangroves, forests, and gardens spanning Puerto Rico. Well-adapted to myriad nesting sites, this Emerald hummingbird flits freely, relying on a diverse nectar supply to counter any migration need. Learn how keeping multiple doors open through habitat connectivity sustains this abundantly welcome wildcard across the island.
Preview a gleaming rainforest gem, the Puerto Rican Euphonia finch, recently proven genetically distinct from its Hispaniolan counterpart. Understand how substantiating this brilliant blue and yellow species as an endemic taxon underscores Puerto Rico's precious biodiversity. Explore outstanding questions about diet, breeding ecology, habitat range and conservation status needing research to inform appropriate protections.
Uncover the mysteries of an expertly camouflaged rainforest bird, the Puerto Rican Lizard Cuckoo, capable of vanishing before your eyes after beckoning you with its eerie yet alluring calls. Understand how mature broadleaf cover supports this specialist predator, efficiently capturing frogs, lizards, and insects high in the canopy to sustain its cryptic existence.
Rediscover a ghostly lost species - the Puerto Rican Nightjar - emerging phantom-like from rapidly vanishing subtropical dry forests still echoed by its mysterious calls. Learn about the nocturnal insectivore's distinctions, specialized habitat needs, threats from encroaching human activity, and why protecting this specialized niche remains essential to ensure the shy bird's continued existence.
Discover a uniquely vibrant island songbird, the Puerto Rican Oriole (Icterus portoricensis), where plumage bright as its voice contrasts prevailing theories on sexual dichromatism. Follow this adaptable species foraging on insects, fruits, and lizards across diverse wooded to developed areas as it steadfastly continues ancestral island lineages.
Discover a versatile nocturnal raptor, the Puerto Rican Owl (Gymnasio nudipes), stealthily ruling the island's forests and urban areas under cover of night. Follow its prowess capturing large insects and small vertebrates to sustain viable populations. Understand how this savvy Screech owl's adaptability across wooded to developed areas enables its continued success.
Check the brilliant hues of Puerto Rico's unofficial national bird, the Puerto Rican Spindalis (Spindalis portoricensis), flickering like an island flag across forests and farms where this frugivore finds refuge. Understand how although adaptable to human-altered areas, habitat integrity is still paramount to enduring conservation for this vivid and voiceful endemic songster.
Trail a voiceful rainforest insectivore, the Puerto Rican Tanager (Nesospingus speculiferus), through remote protected sanctuaries sustaining this species' specialized cloud forest niche now endangered by climate change and urban encroachment. Understand why this blue-hooded songster's reliance on undisturbed canopy cover makes conservation of prime breeding grounds an emergency for securing its future.
Marvel at Puerto Rico's tiniest rainforest resident, the diminutive 11-cm Puerto Rican Tody (Todus mexicanus), using masterful maneuverability to exploit dense broadleaf cover when hunting aerial and leaf-lurking insects. Trace survival adaptations from lower metabolic rates to intricate nest tunnel construction to clutch production aligned with seasonal food availability.
Follow the Puerto Rican Vireo's (Vireo latimeri) melodious voice echoing across lush rainforest canopies, where this prime songster and insect-hunter is now increasingly challenged by hostile cowbird invaders. Learn specific conservation actions to secure this species' specialized nesting requirements and protect fruit sources supplementing its distinctive territorial songs.
Check the skills of Puerto Rico's sole endemic woodpecker, the Puerto Rican Woodpecker (Melanerpes portoricen), adept at chiseling into aged tree snags and woody fruits across protected island forests and tree groves. Appreciate the woodpecker's role as ecosystem architect engineering cavities subsequently used by various secondary nesting birds.
Trace an endemic icterid, the radiant Yellow-shouldered Blackbird (Agelaius xanthomus), through extreme population plunges from habitat destruction to intensive recovery efforts centered on dry forests and mangroves. Learn how strategic protections aid this species' gradual rebound despite ongoing threats from cowbirds, rats, mongooses, and disease.
This review traces Puerto Rico’s treasured diversity of endemic birds, spanning parrots to hummingbirds, woodpeckers, songsters and raptors. While some species like the Puerto Rican Tody and Screech-Owl thrive island-wide thanks to adaptability, most now cling to shrinking niches as forests fall to urbanization.
Yet even well-adapted species remain vulnerable if climate change unravels delicate ecological balance. As stewards protecting the Puerto Rican Amazon’s last wild bastions or guiding the Yellow-shouldered Blackbird’s resurrection from just a dozen pairs, ongoing vigilance remains vital across managed and wild-land habitats.
Safeguarding sufficient rainforest to shelter the melodious Puerto Rican Vireo, intact dry scrub preserving the Adelaide’s Warbler, and mature peaked woodlands hosting the rare Elfin Woods Warbler is now an urgent responsibility. Conserving habitat purity allows birds to shift elevations while securing food resources key to breeding cycles and climate resilience.
Puerto Rico’s future relies on conserving these avian gems not only as moral imperative but also as ecosystem and cultural heritage.
Responsible development policies, public education, and community values centered on resource sustainability set the stage so Puerto Rico’s rare birds can continue brightening their island home.
