In reply to John Rogers (The Press, April 27) regarding the early arrival swallows, we too have also noticed the presence of these birds.

These welcome birds nest in number every single year in the barns and outbuildings where our swan rescue charity is based, and we saw our first swallow arrive on April 14.

Coincidentally, the bird-ringing group of which I am a qualified and licensed bird ringer, caught and rung its first swallow of this year on the March 31 near Sheffield, which is extremely early for this species.

Furthermore, a large number of mute swans throughout the local area have nearly finished nesting, and in one case a pair have hatched six cygnets by April 13; nearly a month early.

Should we be worried? I think so. This is yet another sign that we humans are slowly destroying this planet, the amazing wildlife, and slowly but surely ourselves.

We have to learn that we must live alongside wildlife, not continuously persecute it.

When will those who shoot, hunt and kill for fun learn to respect our wildlife like those of us who spend all of their time and efforts in saving these creatures?

Please, take a little thought for your actions, before it is too late.
