Food supplements were provided to Moorhens Gallinula chloropus during production of their first brood, to test whether food availability limited the number of broods they could rear in a season. Supplemented territories had shorter inter‐clutch intervals when individual differences were held constant, although they did not produce more broods. Because unmanipulated birds with short inter‐clutch intervals produced more broods, food availability may be one of several factors limiting the production of multiple broods and therefore reproductive success.
