Slaty-crowned Antpitta

The slaty-crowned antpitta or slate-crowned antpitta (Grallaricula nana) is a species of bird in the family Grallariidae. It is found in Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela. == Taxonomy and systematics == The taxonomic divisions and subspecific range limits of slaty-crowned Antpitta are far from resolved. As of 2024 the slaty-crowned antpitta has these six subspecies assigned: G. n. occidentalis Todd, 1927 G. n. nana (Lafresnaye, 1842) G. n. hallsi Donegan, 2008 G. n. nanitaea Donegan, 2008 G. n. olivascens Hellmayr, 1917 G. n. kukenamensis Chubb, C, 1918 What are now the two subspecies of the Sucre antpitta (G. cumanensis) were previously treated as subspecies of the slaty-crowned. Some authors have suggested that G. n. kukenamensis should be treated as a full species but this suggestion has not gained wide support. The Clements taxonomy does note it within the species as the "Slate-crowned Antpitta (Guianan)" distinguished from the other five subspecies grouped as the "Slate-crowned Antpitta (Slate-crowned)". == Description == "Grallaricula are very small Andean antpittas, found mostly in low dense vegetation (such as treefall gaps, stream edges, and bamboo thickets)."
