RESUMO
Nest and or nest site reuse within and between breeding seasons was reported by the Euler's Flycatcher (Lathrotriccus euleri), the Sepia-capped Flycatcher (Leptopogon amaurocephalus) and the Gray-hooded Flycatcher (Mionectes -rufiventris) in forest fragments from southeastern Brazil. Nest and or nest site reuse between some years was frequent within a single breeding season by the Sepia-capped Flycatcher. Nest reuse, however, was not related to nesting success in the previous breeding attempt. Nest turnover rates (movement to a new site between years) were low for L. amaurocephalus, intermediate for L. euleri and high for M. rufiventris.

Foram registrados vários eventos de reutilização de ninho ou do sítio de nidificação dentro e entre estações reprodutivas por Lathrotriccus euleri, Leptopogon amaurocephalus e Mionectes rufiventris em fragmentos de floresta do sudeste do Brasil. A reutilização do ninho ou do sítio de nidificação ocorreu entre estes tiranídeos e foi freqüente dentro de uma única estação reprodutiva para L. amaurocephalus. A reutilização do ninho, contudo, não foi relacionada ao sucesso das tentativas anteriores. As taxas de retorno ao ninho foram baixas para L. amaurocephalus, intermediárias para L. euleri e altas para M. rufiventris.
