Bicolored Antpitta Grallaria rufocinerea

  • Order: Passeriformes
  • Family: Grallariidae
  • Polytypic: 2 subspecies
  • Authors: Harold F. Greeney



The foraging behavior of Bicolored Antpitta is not described in detail, but is presumably similar to other montane members of the genus. This species is among the many species of Grallaria which have been readily trained to show up and receive food at worm-feeding stations (Woods et al. 2011, Greeney 2012). Recently, Bicolored Antpitta has been observed following ant swarms (Nieto-R. and Ramírez 2006) and, based on the suggestions of Greeney (2012) it seems likely that it is a species that least occasionally also follows large animals such as tapirs and bears.


There are no published data on territorial defense, maintenance, or fidelity for Bicolored Antpitta. Territory size has not been well established either, but Renjifo (1991) estimated 1.6-5 birds along a 10 km transect, and Kattan and Beltran (1999) estimated 3.7-5.7 birds per 1 km transect.

Sexual Behavior

Not described (but see Vocalizations), probably monogamous.

Social and interspecific behavior

No published information; presumably is primarily solitary.
