Wire-crested thorntail

The male wire-crested thorntail (Discosura popelairii) has a distinctive long, thin crest of wire-like feathers extending from the forehead, along with narrow tail feathers ending in small spatule-like tips. Males are more ornate than females, which lack the crest and elaborate tail.

The species inhabits the Andean foothills of Colombia, Ecuador, and Peru, typically at elevations between approximately 600 and 1,800 meters. It favors humid forest edges and clearings with abundant flowering plants.

The wire-crested thorntail is affected by ongoing deforestation and habitat fragmentation across its limited Andean range. Conversion of forest to agriculture and pasture has reduced the availability of the flowering plants the species depends on for nectar.

The wire-crested thorntail was described in 1846 and given the scientific name Discosura popelairii. It belongs to the Trochilidae family and shares its genus with other thorntail hummingbird species found in the Neotropics.
