A team of researchers in England is seeking volunteers to help them understand the evolution of bird bills. The team is from the University of Sheffield's Department of Animal and Plant Sciences and they are scanning 10,000 bird bills.  Once completed, this will be the largest study of bird bills ever undertaken.

How can you help? The 3D scans are incredibly detailed but before the team can use them they require a process called landmarking. Landmarking involves placing points on features of the bill that are common to all specimens. The team will use the landmarks to mathematically describe the shape of bills so that they can compare and test how they differ among species. Visit their website at www.markmybird.org to sign-up and start landmarking.
