Got a pesky pigeon flock hanging out at your place?
Why not count 'em for Adam....
Adam Rogers is doing a study of feral pigeon colour varieties and this link http://youtu.be/yVmSjdpWDug
gives the Youtube recording of the winterwatch slot that has put his work into the public domain. Worth watching.
You can link directly into his web site at www.feralpigeonproject.com and enter your findings.
A hyper link to another fascinating study is
