The natures voice podcast comes from the Royal Society for the Protection of Birds (RSPB) and appears monthly. The subject matter is usual relevant to those with a casual interest in birds primarily in the UK although they do cover international topics as well. It is presented in a casual manner and the items are usually a conversation between the host and a member of RSPB staff or occasionally a celebrity birder such as Bill Oddie.
I look forward to each months podcast as they tend to be very topical and related to the happenings in that month.
Available from iTunes or from the RSPB website
