With a predominantly black head and upper body, the Spangle-Cheeked Tanager’s breast and upper areas share a similar hue, accentuated by mesmerizing blue scaling on the breast, sides of the face, and neck. A rufous crown adorns the top of its head, while its wings and tail are edged in shimmering blue, complemented by a green rump and cinnamon belly.

While males and females bear a striking resemblance, males boast more extensive blue scaling, adding an extra dimension of splendor to their appearance. Juvenile birds, on the other hand, exhibit a more subdued version of their male counterparts, lacking the crown patch and displaying less visible scaling.

Endemic to Costa Rica and Western Panama, the Spangle-Cheeked Tanager finds sanctuary in forests rich with epiphytes, favoring canopy habitats ranging from 1,200 to 3,000 m (3,900 to 9,800 ft) above sea level. They can also be spotted in semi-open areas, forest edges, and secondary growth, showcasing their adaptability to diverse environments.

During the breeding season, these remarkable birds construct cup-shaped nests nestled among tree forks or branches adorned with epiphytes. Lined with bromeliad leaves, the nests provide a cozy sanctuary for the laying of two eggs, ensuring the continuation of their species.

Despite habitat pressures and human encroachment, the Spangle-Cheeked Tanager is classified as of Least Concern on the IUCN Red List. However, continued conservation efforts are essential to safeguarding its habitat and ensuring its long-term survival in the wild.
