The message
from "David Hill" contains these
words:

My biological control of caterpillars has wings.....the Robins and the Tits
do a very good job here.

Perhaps you have more mixed planting. My vegetable area is somewhat away
from other parts of the garden. I have planted native hedging etc to
encourage the birds more, but until it grows more and until I experiment
more with companion planting, the birds I guess will continue to flock
to other parts of the garden instead.
