Unidentified pteroglossus sp.?StillImageDrawing depicting: Unidentified pteroglossus sp.?Gould 2036-2041 share a dynamic which suggests the hand of Hart; all 5 include a principal bird perching, or in the case of Gould 2040 flying, in a downward diagonal.Drawing on tissue, with some marks of correction. Principal toucan ca. 18" long (Gould's birds are "the size of life" unless stated otherwise) plus 2 others more distant. Long, strongly-hooked bill, somewhat like Pteroglossus viridis or Pteroglossus humboldtii. Not found in the published editions of the Monograph of the Ramphastidae, or family of toucans. What the purpose of these drawings may have been is unclear; perhaps Gould intended a further revision and extension of the work.ku-gould:18295https://digital.lib.ku.edu/ku-gould/18295Gould 2036OrnithologyOrnithological illustrationelectronicimage/tiffThis work is free of known copyright restrictions.
