This is the smallest and the most common and widespread of the three tree-finches. It is a small Darwin’s Finch with a short and stubby rounded bill. Males are black hooded, olive-brown on the back and white on the belly; while females are browner and streaked, including on the breast. This is often one of the commonest of the Darwin’s Finches along with the Small Ground-Finch (Geospiza fuliginosa). The Small Tree-Finch however is found only in areas with forest, agricultural areas with threes, or in the arid or transition zone where taller shrubbery is found. They mostly forage up in the foliage, rather than on the ground. Food appears to be a mix of seeds, fruit and insects. Where found with the Large Tree-Finch (C. psittacula) the Small Tree-Finch is more common and has a wider habitat breadth, while the Large Tree-Finch tends to be found in areas with larger and older trees.
