Abstract
(1) Trade-offs between brood size and offspring growth and survival were manipulating the size of 221 great tit Parus major L. broods between 1983 (2) Nestling mass, wing length and tarsus length were inversely related to Hatching date also affected nestling growth, but its effect differed between Intrabrood variability in nestling size increased with brood size. (3) Nestling survival was inversely related to brood size. Small nestlings suffered mortality than large ones. The difference in nestling survival rate between categories was too small to equalize their productivity. (4) Fledgling survival to the autumn and to the following breeding season inversely related to brood size; fledglings from reduced broods survived better from control... (More)

The fledglings increased with their size as nestlings and decreased with their hatching (5) The sex-ratio among independent fledglings was affected by brood size tion; proportionally more males survived in enlarged than in reduced broods. (6) Dispersal distance of juveniles was not affected by brood size, size hatching date, whereas it was affected by sex.
