Megjegyzések:	The frequency of extreme meteorological events such as heat waves and rainstorms is predicted to increase withclimate change. However, there is still little information about how extreme weather influences reproduction inanimals. It may not only affect breeding success but might also alter offspring sex ratio if males and females aredifferentially sensitive to meteorological conditions during development. We investigated the relationship betweenmeteorological conditions and reproductive success over 6 years in a house sparrow population in central Europe.We found that hatching success increased with the number of extremely hot days (daily maximum >31?C) anddecreased with the number of extremely cold days (<16?C) during incubation, although the latter effect held only forclutches with relatively short incubation periods. Fledging success was unrelated to weather variables. However, thefrequency of extremely hot days had a negative effect on fledglings' body mass and tarsus length, although both ofthese traits were positively related to average temperature. Additionally, fledglings' body mass increased with thelength of period without rainfall before fledging. Male to female ratio among fledglings did not differ from 1:1 and didnot vary with weather variables. The magnitude of the effects of extreme meteorological events was usually small,although in some cases comparable to those of ecologically relevant predictors of reproductive success. Our resultsindicate that meteorological conditions have complex effects on breeding success, as the effects of extreme weathercan differ between different aspects of reproduction and also from the effects of overall meteorological conditions.
