This for me is a must listen every week. This radio show from the Boston area of the USA, hosted by Ray Brown, deals primarily with the birds of that area but there are often items of more general interest. Having done a bit of birding in the USA I enjoy the weekly mystery bird competition as I try to figure out exactly what the bird heard and described is. Surprisingly since it is over 5 years since I was last in the USA I still manage to get some right!
A thoroughly entertaining listen
