Resumo
This note first describes two instances of Peregrine falcons (Falco peregrinus tundrius) capturing fish in different places in Brazil. The first record was in the Ibirapuera Park, municipality of São Paulo, where an adult male swept and captured a fish on the lake's surface, as a typical fishing raptor's strategy. The second one was an adult female catching fish in a salty lagoon in the municipality of Florianopolis. She used vertical diving, surprisingly dipping into water. In both circumstances, falcons had the opportunity to capture birds but they still opted to fish. Although Peregrine falcons mostly prey on birds, there are already some records of feeding on mammals, reptiles, and insects. There are some possible reasons why Peregrine falcons would go fishing, but advanced studies are necessary to test them.
