Provide supplementary food for woodpeckers to increase adult survival
Another analysis (Doherty & Grubb 2003) of the same data as Doherty & Grubb 2002 found that downy woodpeckers Picoides pubescens did not have higher nutritional statuses (judged by the size of feather growth bars) than woodpeckers in unfed control woodlots. The impact on three songbird species is discussed in ‘Provide supplementary food to increase adult survival – Songbirds’.
