Fiery-throated Hummingbird

Panterpe insignis

Se vedete la gola in buona luce, non c'è modo di confondere questa bellezza: nessun altro colibrì combina ogni colore dell'arcobaleno su gola e petto. In scarsa luce, potrebbe essere scambiato per altri colibrì piuttosto grandi come il Colibrì di Talamanca. Cercate la coda blu-nera scura, il becco di media lunghezza con rosa alla base e il groppone blu, o semplicemente aspettate che giri la testa. Sessi simili. Si trova in foreste montane e ai margini, principalmente da 1500m al limite degli alberi. Visita frequentemente le mangiatoie.

Identificazione

The fiery-throated hummingbird is 10.5 to 11 cm (4.1 to 4.3 in) long. Males weigh 5.9 to 6.2 g (0.21 to 0.22 oz) and females 4.9 to 5.2 g (0.17 to 0.18 oz). Within each subspecies the male and female are alike. All have a mostly black bill with a pink base to the mandible and a small white spot behind the eye. The nominate P. i. insignis has a glittering royal blue crown and the rest of the face and nape are black. The back is bright metallic green that becomes bluish green on the uppertail coverts. The tail is blue-black. The center of the throat is brilliant rosy coppery orange and the sides are golden green. It has a violet-blue patch on the center of the breast and the rest of the underparts are bright green to blue-green. Subspecies P. i. eisenmanni is slightly smaller than the nominate but has a much shorter bill. The black of the neck extends onto the upper back and the blue-violet of the chest extends into the belly. The uppertail coverts are mostly blue.

Areale e habitat

The nominate subspecies of fiery-throated hummingbird is found from the Cordillera de Tilarán in north-central Costa Rica southeast to Bocas del Toro and Chiriquí provinces of far western Panama. P. i. eisenmanni is restricted to the Cordillera de Guanacaste in northwestern Costa Rica. The species inhabits a variety of wooded landscapes including montane forest, cloudforest and elfin forest. It also occurs in more open landscapes like the lower edge of páramo, secondary forest, and pastures with many trees. It mostly remains in the forest canopy but occurs in shrubs low down at the forest edge and in clearings. In northern and north-central Costa Rica it occurs at elevations from 1,600 m (5,200 ft) to summits at up to 2,000 m (6,600 ft); further south in higher mountains it ranges between 2,200 and 3,200 m (7,200 and 10,500 ft).
