Abstract
The Horned Sungem Hummingbird ( Heliactin bilophus ) is a typical savannah hummingbird inhabiting opened phytophysiognomies in areas of Cerrado, Caatinga, highlands and plains with low vegetation. There are few studies about its feeding habits and little known about its behavior patterns. Here we report the bird feed behavior on two plant species Amphilophium elongatum and Sinningia sp. Trough illegitimate visits to the floral nectary, H. bilophus obtained food acting as a nectar robber. This foraging strategy included new sources of food for the hummingbird and could represent negative effects to the related plant species. Keywords: bird-flower interactions; food resources; floral visitor.
Highlights
Comportamento pilhador do beija-flor chifre-de-ouro (Heliactin bilophus) (Aves: Trochilidae) em duas espécies de plantas dos gêneros Amphilophium Kunth (Bignoniaceae) e Sinningia Nees (Gesneriaceae)
Trough illegitimate visits to the floral nectary, H. bilophus obtained food acting as a nectar robber
There are cases where the visitors do not act in the pollination, accessing only the nectar of the plant through holes made at the base of the external part of the flower going directly to the floral nectar
