I. yariguierum has been reported (blue squares; unfilled squares = unconfirmed records). All A. I. yariguierum records post-date Paynter (1972). Also shown are known ranges of/i. /. elaeoprorus (unfilled red circles); A. I. caucae (purple-filled circles); and^i. /. spodionotus (unfilled pink ellipses) in Colombia, based on specimens, published literature, data fi-om Project Biomap and additional sight records reported to the authors. Apparent gaps in distribution are partly due to observational lacunae, sometimes exacerbated by deforestation, and partly due to ranges of congeneric ecological competitors (see Remsen & Graves 1995). The southernmost record of ^. /. elaeoprorus in the West Andes and the northernmost, from the Serrania de San Lucas, are from data supplied by Project Biomap. Both require confirmation. Observadons from the East Andes in Cauca are of birds with a strong white speculum (J. Idrobo in litt. 2005) and therefore appear more likely to be of A. I. caucae than A. I. spodionotus. Of this group, A. I. yariguierum emerges as the taxon known from the largest number of localities in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Ornithologists' Club.
