Résumé :	Handling and bleeding are frequently used procedures in avian research and several studies show that they can exert short-term effects, such as elevation in corticosterone levels. However, the long-term effects of exposure to such manipulations are largely unknown, but could have important implications, especially for much of the long-term research on birds and experiments that involve longitudinal assessments. In this study, we evaluated the effect of handling and bleeding on some physiological and behavioural parameters. Hand-reared Great Tits Parus major originating from wild nests were used in two different experiments for other purposes. In these experiments, the birds were exposed to different frequencies of bleeding and handling events across a period of
