Does anyone have any good tips for persuading blackbirds not to throw bark
mulch over the lawn when foraging in the borders?
With a large garden and a lot of formal beds, the benefits of weed
supression are being offset by the time needed to clear up each day.
Any suggestions will be gratefully received.

They may be making a mess, but they wouldn't be doing it if they weren't
finding food. I think you have to balance the mess against the possibly,
even probably in the case of slugs and snails, harmful critters they are
eating.
