Summary
As part of a general investigation into the energy and nutrient requirements of female birds during egg-laying, this study reviewed the evidence from previous published studies on the effects of supplementary feeding on the laying date, clutch size and egg size of breeding birds.
A review was conducted of published studies of supplementary feeding experiments in birds. Studies were classified according to the timing of food supplementation (i.e. whether started before or during the breeding season) and the length of time for which food was provided. The effect of supplementary food provision on the timing of egg-laying, clutch size and weight of eggs was summarised for each study.
