I am thinking of pruning my (Leylandii) hedge. I know from the past
that blackbirds, the only birds other than starlings and pigeons I
have ever seen in my garden, nest in them. I also noticed today that
blackboys were trying to convince blackgirls that mating time is
nigh.

Is the time wrong now to prune my hedge? When is it a good time to do
so?

Thanks in advance,
Kostas
