Amazonian Grosbeak Cyanoloxia rothschildii

  • Order: Passeriformes
  • Family: Cardinalidae
  • Monotypic
  • Authors: Drew Fitzgibbon and Nicholas L. Block



The general behavior of Amazonian Grosbeak is poorly documented; this species typically remains concealed in dense understory vegetation, and is heard much more often than it is seen.


There is very little information on territoriality in Amazonian Grosbeak. At one site in southeastern Peru, one pair had a territory estimated at 15 ha in extent, and its local population density was estimated to be 1.5 pair/100 ha (Terborgh et al. 1990); a similar density, 2 pairs/100 ha, was estimated at a study site in French Guiana (Thiollay 1994).

Sexual Behavior

Little information, but Amazonian Grosbeak often is encountered in pairs, so it presumably is at least socially monogamous.

Social and interspecific behavior

Amazonian Grosbeak is solitary or in pairs, and only rarely associates with other species of birds (Hilty and Brown 1986, Schulenberg et al. 2010, Hilty 2003, Herzog et al. 2016).


No reports of predation on Amazonian Grosbeak?
