Diglossa major
The Greater Flowerpiercer (*Diglossa major*) is a captivating medium-sized tanager, measuring approximately 15-16 cm (5.9-6.3 in) in length and weighing between 17-21 grams (0.6-0.7 oz).

This species primarily inhabits humid montane forests, cloud forests, and forest edges, often venturing into shrubby clearings and páramo edges. It is typically found at high elevations, generally between 1,800 to 3,600 meters (6,000 to 11,800 feet) above sea level.
Its primary diet consists of nectar, obtained by piercing the bases of flowers with its specialized bill, supplemented significantly by a variety of insects gleaned from foliage and bark.
