Abstract
Experimentally hand-feeding nestlings of enlarged (+ 3 nestlings) broo ds reduced female weight loss during the nestling period in a single-b rooded Great Tit Parus major population in Scotland but did not affect nestling size. The result is consistent with the existence of a trade -off in parental care between reproductive costs and benefits.
