          Abstract

          We identified the avian assembly that consumes Miconia ligustroides (Melastomataceae) fruit and described its phenophases in a fragment of cerrado vegetation located in southeastern Brazil. The fruiting period occurred between March and June, a period of food shortage. In 2005 and 2008, we registered eighteen bird species consuming fruits, during 156 hours of observations. Species of the families Thraupidae and Tyrannidae were the most representative in the number of visits and fruit consumption. Short visits (less than three minutes) and low incidence of defecation apparently indicate that seeds may be released far from the parent-plant, suggesting dispersal efficiency by the studied assembly. Owing to its characteristics, we believe Miconia ligustroides may be useful in the restoration of degraded areas.

          Identificamos a assembleia de aves que consome frutos de Miconia ligustroides (Melastomataceae) e descrevemos a fenologia dessa planta, em um fragmento de cerrado no sudeste do Brasil. O período de frutificação ocorreu entre março e junho, um período de escassez de alimento. Em 2005 e 2008, foram registradas 18 espécies de aves consumindo frutos, ao longo de 156 horas de observação. Espécies das famílias Thraupidae e Tyrannidae foram as mais representativas em número de visitas e consumo de frutos. Visitas curtas (menos de três minutos) e a baixa incidência de defecação, aparentemente, indicam que as sementes devem ser liberadas longe da planta-mãe, o que sugere eficiência na dispersão pela assembleia estudada. Em função de suas características, acreditamos que Miconia ligustroides pode ser útil na restauração de áreas degradadas.

              Birds and mammals are important seed dispersers and their diversification in the Cretaceous may have created niches for many plant specialists on scattered resources. Maintaining sexual recombination through wind pollination in such sparse populations is difficult, and so angiosperms with their sophisticated systems for insect pollination were favored in many critical situations.
