摘要：The diet of the Blackburnian Warbler ( Dendroica fusca ) has been reported to include mainly insects and occasionally fruits. We observed this species eating Andean Oak ( Quercus humboldtii ) catkins in the Colombian Andes. Apparently an opportunistic exploitation of a temporarily superabundant resource, this phenomenon has been reported for other wintering boreal migrants. We briefly review the effects of flower consumption for the plant and possible benefits for the bird.
