This is the less common brown morph of the subspecies G. b. ucayalae. Compared to the red morph, the pale head streaking and tail banding are more distinct. Also note the white chin patch. The gray morph found in other populations does not occur in this subspecies. Sometimes spelled "Pygmy Owl" without the hyphen but see: http://www.museum.lsu.edu/~Remsen/HyphensBirdNames.htm.
