Abstract

RIOS, JUAN MANUEL; ZARCO, AGUSTÍN; MOSCA-TORRES, MARÍA E.  and  SABAT, PABLO. Diet of Phytotoma rutila (Passeriformes: Cotingidae) in the central Monte desert, Argentina. Gayana (Concepc.) [online]. 2014, vol.78, n.1, pp.21-24. ISSN 0717-6538.  http://dx.doi.org/10.4067/S0717-65382014000100003.

Botanical composition of the diet of White-tipped Plantcutter Phytotoma rutila in the central Monte desert from Argentina, was determined by microhistological analysis of excreta. In both sexes, the diet was composed by a high proportion of fruits (26.8%) and leaves (35.6%) from the shrub Lycium tenuispinosum (Solanaceae) and leaves from the tree Prosopis flexuosa (Fabaceae) (26.8%). P. rutila is a predominantly folivorous bird with a high consumption of fruit during summer, when these items are abundant, which shows an opportunistic behavior.
