About the Garden Bird Feeding Survey
The GBFS commenced in 1970/71 to examine the increasingly popular activity of providing food for birds in gardens during winter and is the longest-running study of its kind in the world. With food and feeders changing so much over the years, the GBFS has played an essential role in examining the effects on birds using these resources. This unique dataset has been used in a number of studies, illuminating the effect garden feeding has had on birds over the past 50 years.
