When we moved here, we were indundated with sparrows, starlings and crows. Over they years they have all but disappeared. As they disappeared, we had different birds appearing; nightingales, kingfishers, jays, woodpeckers and a whole host os smaller birds; ****, finches, buntings etc. Now all we have are the occasional pair of wood pigeons and a pair of magpies. Not a robin or blackbird in sight. We have started seeing small groups of parakeets and wondered if they could have any relevance?
