Diglossa sittoides
The Rusty Flowerpiercer, *Diglossa sittoides*, is a small, agile tanager renowned for its specialized bill and distinctive coloration, making it a favorite among birders in its Andean range. Measuring approximately 11-13 cm (4.3-5.1 inches) in length and weighing around 10-14 grams, this species is characterized by its striking rusty orange underparts, dark slate-gray to black upperparts, and a unique, sharply upturned, hooked blue-gray bill.

This species typically inhabits humid montane forests, forest edges, shrubby clearings, and bushy slopes, often frequenting gardens and cultivated areas. It is found at elevations generally ranging from 1,500 to 3,000 meters (4,900-9,800 feet) above sea level.
Its diet primarily consists of nectar, which it obtains by piercing the base of flower corollas, supplemented by a significant intake of small insects and arthropods gleaned from foliage. Occasionally, small berries or fruits may also be consumed.
The Rusty Flowerpiercer is a highly active and agile diurnal bird, constantly moving through vegetation in search of food. Its primary foraging strategy involves perching at the base of flowers and using its unique hooked bill to puncture the corolla, extracting nectar without assisting in pollin...
