Olive Finch Arremon castaneiceps

  • Order: Passeriformes
  • Family: Passerellidae
  • Monotypic
  • Authors: Kimberly N. Voelker and David L. Slager



Olive Finch typically forages on or near the ground, advancing with hops (Hilty and Brown 1986, Ridgely and Greenfield 2001a). This finch occupies dense undergrowth and so is difficult to observe, but apparently is not especially shy and sometimes responds strongly to squeaking noises (Ridgely and Greenfield 2001b). In general, the behavior of Olive Finch is very poorly known, but is presumably similar to that of Sooty-faced Finch (Arremon crassirostris), its better-studied sister species in Central America (Ridgely and Tudor 1989).


Olive Finch presumably is territorial, but there are no data on territorial defense, maintenance, or fidelity, or for territory or home range size, for this species.

Sexual Behavior

Little information, but Olive Finch often is seen in pairs and so presumably is at least socially monogamous.

Social and interspecific behavior

Olive Finch is typically seen singly or in pairs.


No information.
