Xenoglaux loweryi (Long-whiskered Owlet)

Wikipedia Abstract

The long-whiskered owlet (Xenoglaux loweryi) is a tiny owl that is endemic to a small area in the Andean mountains in Amazonas and San Martín in northern Peru. It is restricted to cloud forests with dense undergrowth and epiphytes at about 1,890–2,200 metres (6,200–7,220 ft) above sea level. In La Esperanza, the creation of a community run conservation area, supported by community based tourism is intended to ensure the survival of this and other endemic species.

EDGE Analysis

This diminutive owl eluded discovery for many years until 1976, when it was found in the northern Peruvian Andes. It was then another 25 years after its discovery before it was seen again, caught in some mist nets. The species has fascinated birdwatchers and scientists alike due to its remarkable and unique appearance. As its name suggests, it possesses long facial whiskers that protrude around the eyes and bill. The function of these whiskers is as yet unknown, but they are unique to this species and not exhibited by any other member of the Strigidae family. Habitat for this species is diminishing as the Peruvian forest is being cleared for timber, crops and livestock grazing.
