Abstract ∙ Hyacinth Macaws (Anodorhynchus hyacinthinus) feed largely on palm seeds and fruits. Here, we report a pair of Hyacinth Macaws feeding on termites. We visited the nesting tree of a pair of Hyacinth Macaws at the southern border of the Brazilian Pantanal on a monthly basis during one year. Macaws were present during four of these visits, and we recorded them foraging on arboreal termites in their nesting tree during one of the visits. Using their beaks, both macaw individuals repeatedly broke away bark pieces from decaying branches, and handled them with beak and feet to ingest termites found on the inner side of the bark. Nesting in decaying trees likely increases opportunities for Hyacinth Macaws to find termites, and the feeding behavior of these macaws indicates that they are familiar with and able to consume termites. This is the first report of termite consumption by this species.
Resumo ∙ Arara‐azul‐grande (Anodorhynchus hyacinthinus, Psittacidae) comendo cupins Indivíduos de Arara‐azul‐grande (Anodorhynchus hyacinthinus) consomem principalmente sementes de palmeiras e frutos. Reportamos aqui um casal de Araras‐azuis‐grandes consumindo cupins. Visitamos uma árvore de nidificação na borda sul do Pantanal brasileiro mensalmente durante um ano. As araras estavam presentes em quatro visitas, e registramos consumo de cupins presentes na árvore de nidificação em uma visita. As araras repetidamente retiravam com o bico pedaços de casca de ramos podres, e manuseavam os pedaços com o bico e os pés para ingerir cupins presentes na parte interna da casca. Nidificar em árvores senescentes provavelmente aumenta a oportunidade dessas araras encontrarem cupins, e o comportamento alimentar delas indica familiaridade e habilidade em consumilos. Esse é o primeiro registro de consumo de cupins por esta espécie.
