Pigeons are destroying the plants in one of my planter tables

This spring I had sown a few things in my planter table, but nothing really came. What was appearing where dents in the soil and a dill plant that got picked of.

One day my husband saw pigeons feasting in the planter table. For that we have an easy solution. We tied a rope criss-cross over the plant space and pigeons can not land here anymore.

Now the dill can grow and I planted lettuce seedlings which grew well and we are eating off already.

The second planter table, strangely enough, did not get touched by the pigeons. The herbs I planted this spring and a second batch of lettuce I planted only recently as a succession planting.
