Provide supplementary food for wildfowl to increase adult survival Bird Conservation

A randomised, replicated and controlled trial at Karrak Lake in Northwest Territories, Canada, (Gloutney et al. 1999) found that female lesser snow geese Chen caerulescens caerulescens and Ross’s geese C. rossii used supplementary food to different extents during incubation and showed different physiological responses to food. However, both males and females of both species were either heavier, had heavier hearts, more body fat or larger flight muscles when fed, compared to unfed controls. Differences were apparent both after laying and at the end of incubation. Between 250 g and 400 g of cracked and whole corn, durum wheat or shelled rice was provided each day.
