This week SNRG conducted its second Constant Effort Site (CES) Scheme session at Attenborough Nature Reserve.
Due to the amount of rain the past month, wellies were still very much needed! A total of 10 different species were encountered, including our first juvenile bird of the season at this site.
What is the Constant Effort Site Scheme (CES)?
The CES scheme is the first national standardised ringing programme within the BTO Ringing Scheme and has been running since 1983. Ringers operate the same nets in the same locations over the same time period at regular intervals through the breeding season at approximately 120 sites throughout Britain and Ireland.
The Scheme provides valuable trend information on abundance of adults and juveniles, productivity and also adult survival rates for 24 species of common songbird.
