Jean C. Roche's album Birds of Venezuela. Available here on LP.
Jean C. Roché's Birds Of Venezuela, originally released in 1973. The bird on the cover is a potoo; this metal-looking bird is one of the sonorous curiosities of this mad nature, the sound that he produces essentially is a death song that David Toop heard on his 1978 expedition, but was unable to record, amazement playing its role.
LP - Standard LP.
