The exploration of the effects of urbanization on bird demography has attracted much
attention, and several studies found lower reproductive success in towns, which suggested …

Ambient temperature is assumed to be the major cue used by passerines to synchronize
their laying and hatching dates to the expected peak of prey availability. While laying eggs …

The short favorable period of time available for the growth in seasonal environments could
constrain the resources allocation between growth and other life-history traits, and the short …

The timing of breeding often has a profound influence on the reproductive success of birds
living in seasonal environments with rapidly changing nestling food availability. Timing is …

Varying the timing of reproduction in response to local environmental conditions is a key
factor influencing reproductive success. We used 19 yr (1991 to 2009) of data on breeding …

Variation in ambient temperature affects various life stages of organisms. It has been
suggested that climate change not only implies higher global temperatures but also more …

Capsule The onset of incubation relative to clutch completion is highly variable in Great Tits
Parus major, and has important consequences for the duration of the incubation and …

After laying the first egg, a bird can, to a certain extent, adjust the hatching date of the brood
to environmental conditions. However, costs of this adjustment have remained largely …

Birds can, to a limited extent, delay hatching after laying the first egg to synchronize hatching
date to peak food availability by increasing the laying interval between eggs or postponing …

Egg size variation in a Mediterranean Great Tit Parus major population. Egg size variation
