Análise do conteúdo estomacal de algumas aves da Coleção Anatômica do Museu Paraense Emílio Goeldi, ocorrentes no Campus de Pesquisa da instituição

Abstract

Urban birds have very varied feeding habits, and may be: insectivorous, nectarivorous, frugivorous, granivorous and omnivorous. Published studies involving the analysis of the diet of birds are an important tool for the knowledge of species, which can be indicators for the analysis of environmental conditions, however, in the Amazon, there are still gaps regarding the food items of avifauna. The study aimed to qualitatively analyze the stomach contents of species captured in the boundaries of the Research Campus of the Emílio Emílio Paraense Museum (MPEG) and stored in the anatomical collection. We analyzed 34 stomachs belonging to 11 families: Rallidae, Psittacidae, Cuculidae, Trochilidae, Dendrocolaptidae, Furnariidae, Tyrannidae, Vireonidae, Turdidae, Thraupidae and Emberizidae. Of all the stomachs analyzed, 5 were completely full and only 4 were empty. In the specimens of Laterallus exilis and Thraupis episcopus fully intact and preserved seeds were found, showing that both are good seed dispersers. A representative of the species Synallaxis gujanensis was in reproductive period, presenting a large amount of plant material in its stomach. Coleoptera and Hymenoptera predominated in the stomach contents analyzed. The MPEG Research Campus still represents an important source of refuge, feeding and nesting for the studied avifauna.
