Triclaria

Triclaria malachitacea is a midsized green parrot in which males have a unique blue abdominal (belly) patch sometimes extending to the lower breast, and with a relatively long tail for Androglossini. It is another Atlantic Forest endemic found in the lower montane forests of southeastern Brazil ( Forshaw and Knight, 2010). Apparently, the striking and presumably convergent evolution in the plumage of the underparts of this species and that of a similarly sexually dichromatic suboscine passerine Calyptomena hosii of Indonesia has never been noted (fig. 8). Study of the drivers of this convergence would surely be rewarding and presumably may relate to the function of blue in displays of birds inhabiting forests and the forest strata at which the blue is functional in those rainforests (see Endler, 1993).
