Areale e habitat

The neblina metaltail is found from the northern part of Podocarpus National Park in Ecuador's Loja Province south to northern Piura and Cajamarca departments in Peru. It inhabits the edges of elfin forest and páramo, moist landscapes characterized by shrubby growth and small trees. ("Neblina" is Spanish for fog or mist.) In elevation it ranges between 2,600 and 3,650 m (8,500 and 12,000 ft) and is most common between 2,900 and 3,400 m (9,500 and 11,200 ft).

Comportamento

The neblina metaltail is resident throughout its range.<p>The neblina metaltail feeds mostly on nectar but details of its diet are lacking. Males defend feeding territories. In addition to nectaring, it catches small arthropods by sallies from a perch.<p>Very little is known about the neblina metaltail's breeding phenology. The only nest was found in August; a female was on it. The nest was a cup made mostly from moss with lichens on the outside placed in a small cavity on a rock face.<p>The neblina metaltail's vocalizations have variously been described as "a rather loud seet-seet-seet-ti-tttt...and 'a jerky, wiry chatter'."
