          Abstract

          Insects are the staple diet of woodpeckers, but some species also habitually feed on fruits. A few woodpecker species are recorded as flower visitors for nectar intake. We report here on the blond-crested woodpecker (Celeus flavescens) taking nectar from flowers of two canopy species, Spirotheca passifloroides (Bombacaceae) and Schwartzia brasiliensis (Marcgraviaceae), in the Atlantic forest of south-eastern Brazil. Spirotheca passifloroides blooms for three months in the austral winter, whereas S. brasiliensis blooms for two months in the summer. Flowers of both species produce large amounts of dilute nectar. Celeus flavescens visits several flowers per plant touching the anthers and stigmas with its head and throat, and thus acts as a pollen vector. We suggest that woodpeckers may be more frequent flower visitors than previously thought, and that feeding on ripe fruits may be a simple behavioural step for the origin of nectar feeding by Neotropical woodpeckers.

          Insetos formam a dieta básica dos pica-paus, porém algumas espécies também se alimentam habitualmente de frutos e poucas espécies procuram flores para tomar néctar. Registramos aqui o joão-velho ou pica-pau-de-cabeça-amarela (Celeus flavescens) ao tomar néctar de flores em duas espécies de plantas do dossel, Spirotheca passifloroides (Bombacaceae) e Schwartzia brasiliensis (Marcgraviaceae), em Mata Atlântica do sudeste do Brasil. Spirotheca passifloroides floresce por três meses no inverno, ao passo que S. brasiliensis floresce ao longo de dois meses no verão. As flores de ambas as espécies produzem néctar abundante e diluído. Celeus flavescens visita várias flores por planta, tocando as anteras e os estigmas com a cabeça e o pescoço, assim agindo como polinizador. Sugerimos que visitas de pica-paus a flores sejam mais freqüentes do que o suposto e que se alimentar em frutos maduros seria um passo comportamental simples para a origem da tomada de néctar por pica-paus neotropicais.
