Baudó oropendola

The male Baudó oropendola is about 46.5 cm (18.3 in) in length and the female is slightly smaller at 40 cm (15.7 in). This bird is similar in appearance to the black oropendola (Psarocolius guatimozinus), being largely black with chestnut-brown upper parts, but the patches of bare skin on the cheeks are pink, the mantle and wings are more rufous-brown and the flanks are rather more chestnut.[2]

This species is endemic to a small area around los Saltos and de Baudó, in the Chocó Department of north-west Colombia, an area of occupancy of about 4,570 km² (1,764 sq mi). The bird has only been observed in a few isolated locations in river valleys at the edge of humid rainforests, but more recently birds have been sighted in the river valleys of the Rio Siviru and Rio Tipicay near Bajo Baudó, and a location has been found on the coastal plain with sixty inactive nests suspended from Bactris gasipaes palms and Guazuma ulmifolia trees in secondary growth between a banana plantation and the edge of the mature forest.[1]

The International Union for Conservation of Nature has assessed the conservation status of P. cassini as being "endangered"; this is because of the small number of locations from which it is known, and the degradation of its habitat as deforestation takes place for logging, the creation of oil palm plantations, agricultural activities and road-building.[1] It is estimated that the total population of the bird numbers between 1000 and 2500 individuals and is likely to be declining. However the bird is little-known, and there may be other breeding colonies at present unknown; if that proves to be the case, the bird's status may need to be changed to "vulnerable".[1]
