Food Preferences of Winter Bird Communities in Different Forest Types

摘要: Food availability for forest birds is a function of habitat type, management regime, and season. In winter, it also impacted by variations in the weather. current study we assessed food preferences wild bird populations two types (spruce beech) during months November 2010 to April 2011 Schwabische Alb Biodiversity Exploratory, south-western Germany. Our aim was investigate whether local communities preferred fat-rich, carbohydrate-rich or fruits determine how structure, seasonality weather conditions affected preferences. We found higher activity beech forests eleven resident species. observed clear preference fat-rich all both types. Snow cover at stations but did not affect Periods extreme low temperatures increased activity.
