About the Olivaceous Woodcreeper

The olivaceous woodcreeper (Sittasomus griseicapillus) is a passerine bird in subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found from central Mexico south through every Central American country, on the island of Tobago, and in every mainland South American country except Chile, French Guiana, and Suriname.

The olivaceous woodcreeper is the only member of genus Sittasomus. However, taxonomic systems vary in their treatment of the taxon, with some splitting it into two species. The International Ornithological Committee and the Clements taxonomy assign these 15 subspecies to the olivaceous woodcreeper; Clements distributes them among five groups.

"Grayish" group S. g. jaliscensis Nelson, 1900 S. g. gracileus Bangs & Peters, J.L., 1928 S. g. sylvioides Lafresnaye, 1850 S. g. perijanus Phelps, W.H. & Gilliard, 1940 S. g. tachirensis Phelps, W.H. & Phelps, W.H. Jr., 1956
