'A Life With Loons'

Radio 4 last night at 11.30 pm for half -hour had a really interesting programme;
'A Life With - Loons'. In North America - a scientific approach on breeding/ringing/longevity/plumage/calls/feeding/migration etc. It's well worth catching up with if it's repeated - or on the computer i player !!?

TONIGHT - Radio 4 - 11.30 pm - 'A Life With - Ospreys'
