Comportamento

The rose-bellied bunting forages alone or in pairs in the lower to mid-level of its habitat. Its diet consists of seeding grasses and fruit from trees and bushes.<p>Two rose-bellied bunting nests have been described. One found in late July had freshly laid eggs, the other had eggs well along in incubation in late June. The nests were open cups of dead leaves and bark lined with finer material; they were placed in crotches of small saplings. One clutch had three eggs and the other four. No other information about the species' breeding phenology has been published.<p>The rose-bellied bunting's song is "a sweet, slightly burry warble" [1]. Its call is "a wet 'plik' or 'plek'" [2].
