Provide supplementary food for songbirds to increase adult survival
A replicated controlled study in a deciduous wood in southern Sweden in winter 1980 and spring 1981 (Enoksson 1990) found that, although wood nuthatches Sitta europaea made up 28% of all visits to supplementary feeding stations, there was no difference in the time devoted to different behaviours between five fed pairs and nine control pairs. Supplementary food consisted of 60 kg of sunflower seeds supplied continuously from December 1980 until March 1981 at nine feeders spread evenly across the experimental area. The author suggests that the lack of differences could be due to variations in the intensity of foraging, rather than the time spent foraging.
