We recorded interactions between frugivorous birds and plants in the Cerrado and we assessed the role and importance of birds as potential seed dispersers. We analyzed the distribution of recorded feeding events, bird-plant interactions, and bird species composition between savanna and forest formations and between the dry and rainy seasons. Samplings were carried out from August 2009 to October 2010 and from November 2011 to August 2012 by means of line transects and focal observations. We recorded 348 feeding events and 187 interactions involving 44 plant species and 60 bird species. Most of the feeding events were observed in the forests and during the dry season (χ2 = 39.529; gl = 1; p < 0.001). However, no significant difference was found in the number of interactions (χ2 = 15.975; gl = 1; p = 0.06) between the two vegetation formations and between seasons. The bird species composition differed between savanna and forest formations (ANOSIM, R = 0.238; p < 0.001) and between the dry and rainy seasons (ANOSIM, R = 0.223; p < 0.001). Most of the potential seed dispersers were generalist birds that preferentially occupy forests during the dry season. Records of feeding events in forest formations increased in the dry season, indicating that birds use these sites as foraging areas during this period. We suggest that the preservation of forests in predominantly savanna-like ecosystems such as the Cerrado is extremely important for frugivorous birds and for frugivore-plant interactions.

“…Synchronised fruit production may be a strategy to increase the attractiveness of the frugivorous species responsible for seed dispersal (Augspurger, 1981). The fruiting period coincides with the wet season, when many fruits of other ornithocoric dispersion syndrome plants are available in the same area, like: Davila rugosa Poiret (Dilleniaceae) (Francisco and Galetti, 2002a), Ocotea pulchella (Nees) Mez (Lauraceae) (Francisco and Galetti, 2002b), Pera glabrata (Schott) Baill (Euphorbiaceae) (Francisco et al, 2007), Rapanea lancifolia (Ruiz and Pavon) Mez (Francisco and Galetti, 2001) and Zanthoxylum rhoifolium Lam. (Rutaceae) (Silva et al, 2008).…”

The avian guild that consumes Miconia albicans (Melastomataceae) fruits and its phenophases were studied in a fragment of cerrado vegetation located in southeastern Brazil. The fruiting period ocurred between October and January, coinciding with the wet season. Nineteen bird species, mainly of generalistic diets, were registered consuming fruits in 96 observational hours. Species of the families Emberizidae, Thraupidae and Tyrannidae showed the largest number of visits, while those of the families Mimidae and Columbidae, with higher body mass, were responsible for a considerable number of consumed fruits. A correlation was found between body mass and average fruit consumption per visit. Tree height was a relevant factor for bird attraction. Results suggest that M. albicans may be useful in the recovery of degraded areas.Keywords: frugivory, ornitochory, phenology, Miconia, cerrado. Frugivoria por aves em Miconia albicans (MELASTOMATACEAE), em um fragmento de cerrado em São Carlos, sudeste do Brasil ResumoFoi estudada a guilda de aves que consomem frutos de Miconia albicans (Melastomataceae), bem como a fenologia dessa planta, em fragmento de cerrado no sudeste do Brasil. O período de frutificação ocorreu entre outubro e janeiro, coincidindo com a estação chuvosa. Dezenove espécies de aves, a maioria com dieta generalista, foram registradas consumindo frutos em 96 horas de observações. Espécies das famílias Emberizidae, Thraupidae e Tyrannidae apresentaram o maior número de visitas, enquanto aquelas das famílias Mimidae e Columbidae, de maior massa corporal, sobressaíram-se pelo número de frutos consumidos. Foi encontrada correlação entre massa corporal e consumo médio de frutos por visita. A altura das árvores foi um fator relevante na atração de aves. Os resultados sugerem que M. albicans pode ser útil na recuperação de áreas degradadas.

“…Thraupidae are among the most frequent seed dispersers of ornithochoric plants in Brazil (Galetti and Pizo, 1996;Gondim, 2001;Sick, 2001;Francisco et al, 2007;Figueiredo et al, 2008). Although Thraupidae did not efficiently disperse large seeds (Levey, 1987) and sometimes dropped the fruits under the mother plant (Sick, 2001), the small seeds of S. granuloso-leprosum were more easily consumed.…”

The goal of this study was to identify which bird species consume Solanum granuloso-leprosum fruits and disperse its seeds. 60 hours of focal observations were carried out between April and May 2006 on the edge of a deciduous forest fragment in the Uruguay River region, Rio Grande do Sul state, Brazil. Ten species were observed in total removing 443 fruits. Saltator similis removed 61.8% of the fruits, followed by Tangara sayaca (17.1%), Pipraeidea bonariensis (11.7%), and T. preciosa (6.8%), while the remaining six species accounted for only 2.5% of the fruits removed. Most fruit removal occurred early in the day or mid-afternoon. The most common feeding behaviors were picking (60.7%), followed by stalling (23%) and hovering (16%). Birds flew more than 10 m from the fruit plant in 62% of the removal events. All bird species observed here may be considered potential dispersers of S. granuloso-leprosum, as they moved the seeds away from the mother plant where strong competition and predation are likely to occur. Results also suggest that S. granuloso-leprosum may be useful in ecological restoration programs.Keywords: mother plant, ornitochory, pioneer plant, secondary fragment forest. Frugivoria e dispersão de sementes em Solanum granuloso-leprosumDunal (Solanaceae) por aves em Floresta Estacional Decidual ResumoO objetivo deste estudo foi identificar quais as espécies de aves consomem frutos de Solanum granuloso-leposum e dispersam suas sementes. Para tanto, 60 horas de observações focais foram realizadas entre abril e maio de 2006 na borda de um fragmento de floresta decídua na região do rio Uruguai, Rio Grande do Sul, Brasil. Dez espécies foram observadas removendo 443 frutos. Saltator similis removeu 61,8% dos frutos, seguido de Tangara sayaca (17,1%), Pipraeidea bonariensis (11,7%), e T. preciosa (6,8%), enquanto as restantes seis espécies representaram apenas 2,5% dos frutos removidos. A maioria das remoções dos frutos ocorreram no início do dia ou meio da tarde. Os comportamentos alimentares mais comuns foram picking (60,7%), seguido por stalling (23%) e hovering (16%). As aves voaram mais de 10 m da planta de onde removeram frutos em 62% dos eventos de remoção. Todas as espécies de aves observadas aqui podem ser consideradas potenciais dispersores de S. granuloso-leprosum, moveram sementes para longe da planta-mãe, onde a concorrência e a predação são mais susceptíveis de ocorrer. Os resultados também sugerem que S. granuloso-leprosum pode ser útil em programas de restauração ecológica.Palavras-chave: planta mãe, ornitocoria, planta pioneira, fragmento de floresta secundária.
