Range of russet-backed oropendola (in green) |
The russet-backed oropendola (Psarocolius angustifrons) is a species of bird in the family Icteridae. It is found in wooded habitats in the highlands of the northern and central Andes and the Venezuelan Coastal Range, and in lowlands of the western Amazon. It is generally common and widespread. Males are larger than females, but otherwise the genders are similar. Its plumage is mainly olive and brown, and the outer rectrices are contrastingly yellow. The lowland nominate subspecies has a black bill, while the highland subspecies all have pale bills. These have been regarded as separate species, but as they hybridize freely, all major authorities now regard them as a single species.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
