SIR – I was surprised to read Kate Humble’s letter ‘Let’s do all we can to help save nature’ (Worcester News, March 29) for the RSPB’s Stepping Up For Nature campaign.

It seems a strange idea that the RSPB wants us all to help save nature, when the RSPB still continues to support the slaughter of the ruddy duck in this country. This breed of duck has been killed in the hundreds on many reserves simply because it breeds with the white headed duck in Spain (the white headed duck is in decline in Spain).

I stopped my membership of the RSPB many years ago because of these terrible killings.

I this they should call themselves the Royal Society for the Protection of Some Birds.
