Resumo: Nós analisamos as presas consumidas por quatro espécies de corujas que ocorrem no estado do Rio Grande do Sul, Brasil. As amostras foram obtidas a partir da coleta de uma egagrópila de A. clamator (N = 1) e 12 carcaças de Strigiformes atropelados (Tyto furcata: N = 5; Megascops sp.: N = 4; Bubo virginianus: N = 2; Asio clamator: N = 1) encontrados em rodovias do estado entre 2001 e 2019. Nós contabilizamos 40 itens alimentares representados por seis classes animais: Arachnida, Chilopoda, Insecta, Amphibia, Aves e Mammalia. Entre os itens ingeridos por T. furcata estavam a rã-manteiga (Leptodactylus latrans) e o rato-doméstico (Mus musculus). Megascops sp. predou principalmente artrópodes e uma pomba-debando (Zenaida auriculata). Os indivíduos de A. clamator predaram um roedor e Coleoptera, enquanto B. virginianus predou apenas roedores. A análise das presas consumidas por Strigiformes ampliou o conhecimento sobre a dieta do grupo no sul do Brasil.Palavras-chave: Asio clamator; Bubo virginianus; Megascops sp.; Tyto furcata. CONTRIBUTION TO THE KNOWLEDGE OF THE OWLS DIET (AVES: STRIGIFORMES) IN SOUTHERN BRAZIL.We analyzed the prey consumed by four species of owls that occur in Rio Grande do Sul state, Brazil. Samples were obtained from a pellet by Asio clamator (N = 1) and 12 Strigiformes road killed carcasses (Tyto furcata: N = 5; Megascops sp.: N = 4; Bubo virginianus: N = 2; Asio clamator: N = 1) found on highways of the state between 2001 and 2019. We counted 40 food items represented by six animal classes: Arachnida, Chilopoda, Insecta, Amphibia, Aves and Mammalia. Tyto furcata fed mainly on the butter frog (Leptodactylus latrans) and the house mouse (Mus musculus). Megascops sp. preyed mainly arthropods and an eared dove (Zenaida auriculata). The A. clamator preyed a rodent and Coleoptera, while both B. virginianus preyed only rodents. The analysis of prey consumed by Strigiformes increased knowledge about the group diet in southern Brazil.Grande parte das espécies de corujas apresentam hábitos noturnos e crepusculares, o que dificulta sua visualização e o estudo de seus hábitos alimentares (Sick 1997). A dieta dessas aves inclui variados artrópodes e vertebrados, como anfíbios, répteis, aves e mamíferos de pequeno e médio

We report the sighting of a specimen of Black-headed Gull (Chroicocephalus ridibundus) in Saint Peter and Saint Paul Archipelago (SPSPA), Brazil, in the mid-Atlantic Ocean. Chroicocephalus ridibundus is a Palearctic species that breeds throughout Europe. Part of the population spends winters in the Mediterranean and coasts of Africa, and a small breeding population remains in the northeast coast of North America. The specimen was on the island for 27 days, between 09 February and 06 March 2020. The gull was identified as a first-winter bird based on its plumage. We conclude that the vagrancy of yet another Old World species at the oceanic SPSPA in the western equatorial Atlantic Ocean was caused by the southwesterly trade winds of the Intertropical Convergence Zone. To our knowledge, this is the first documented record of C. ridibundus in the Brazilian territory.
