Foraging behavior of kaempfer's woodpecker (celeus obrieni), a bamboo specialist
Because of the patchiness of their habitat, its perceived low conservation value, and tendency to burn, bamboo-specialist birds are vulnerable to habitat loss. We documented the habitat use and foraging strategies of Celeus obrieni, Kaempfer's Woodpecker, in forested cerrado (savanna) with patches o...

Because of the patchiness of their habitat, its perceived low conservation value, and tendency to burn, bamboo-specialist birds are vulnerable to habitat loss. We documented the habitat use and foraging strategies of Celeus obrieni, Kaempfer's Woodpecker, in forested cerrado (savanna) with patches of the bamboo Guadua paniculata near Pium, Tocantins, Brazil. We surveyed for C. obrieni, measured vegetation structure at 30 sites where it was detected and 23 where it was not detected, then compared vegetation characteristics through nonmetric multidimentional scaling and one-way analysis of similarity to determine whether C. obrieni was specializing on particular habitat characteristics.
