Urbanisation imposes new constraints on wildlife, as cities are characterized by multiple abiotic and biotic modifications of the natural environment. Studies of paired bird populations show reduced breeding success in urban as compared to rural habitats, however, the mechanisms involved are not well understood. In particular, alterations of the environment in cities are likely to provoke an increase in the level of physiological stress, which may directly or indirectly affect reproductive decisions and consequently reproductive success. I will present new data obtained in populations of great tit (Parus major) and blue tits (Cyanistes caeruleus) breeding in Ile de France, investigating how physiological stress relates to breeding success.
