I found that Blackcaps love these purple callicarpa berries.
A pair came in October 2009 and stayed until March 2010.
Jan 2nd 2011 now and a pair have been visiting the garden daily for
a month or so. I wonder whether it is the same pair.
There are no Callicarpa berries this year but my rib of beef fat and
bread balls seem to be a hit.
