Black-banded Woodcreeper

The black-banded woodcreeper (Dendrocolaptes picumnus) is a sub-oscine passerine bird in subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found discontinuously from Chiapas, Mexico, to Panama and in every mainland South American country except Chile and Uruguay. == Taxonomy and systematics == The black-banded woodcreeper's taxonomy is unsettled. The International Ornithological Committee (IOC) and the Clements taxonomy recognize these 10 subspecies. Clements arranges them in three groups. "Spot-throated" group D. p. puncticollis Sclater, PL & Salvin, 1868 D. p. seilerni Hartert, EJO & Goodson, 1917 D. p. olivaceus Zimmer, JT, 1934 "Black-banded" group D. p. costaricensis Ridgway, 1909 D. p. multistrigatus Eyton, 1851 D. p. validus Tschudi, 1844 D. p. picumnus Lichtenstein, MHC, 1820 D. p. transfasciatus Todd, 1925 "Pale-billed" group D. p. pallescens Pelzeln, 1868 D. p. casaresi Steullet & Deautier, 1950 BirdLife International's Handbook of the Birds of the World (HBW) does not recognize D. p. casaresi, apparently including it within D. p. pallescens. Subspecies D. p. transfasciatus and D. p. pallescens were each treated as separate species by some early 20th century authors but have been included in D. picumnus since about the middle of that century. D. p. transfasciatus is also sometimes proposed as a…
