Who's been stealing my blackcurrants?

Blackbird caught in the act.  Nikon D7000

5th July 2013

My black currants are starting to look juicy, but seem to have been disappearing.   There has been a lot of purple bird poo on the patio too in the last few days, suggesting the thieves may have wings.

With the help of a small radar (a RAT-150, one of our latest products being developed ...) I managed to catch one of the varmints in the act.

Not content with just eating up the fallen berries, this blackbird was attempting to snatch them in flight!
