Message: <blockquote data-quote="Jos Stratford" data-source="post: 3599630" data-attributes="member: 12449">I do not recall saying I did not have an idea of what things were like before 4G in Lithuania - my observations and my feeding stations pre-date the arrival of 4G by more than ten years and for the species I mentioned at the sites I observe, I can say there has been no decline. You asked specifically about Tree Sparrows - I also maintain a feeding station at my home near Vilnius (ie. not the locality I provided the earlier data) and for this I have figures from the winter of 1999/2000. This is not very far from a 4G tower, as is everywhere in Lithuania (remember this country has the best 4G coverage in Europe, 3rd best in the world).Tree Sparrows have actually shown a sustained increase at this site - winter total in 1999/2000 was 41 birds, the number similar the next couple of winters too. This pre-dated 4G. Numbers thereafter, running through and beyond the period that 4G arrived (from 2010), have gradually increased year-on-year to reach an average winter number of about 80, even higher some winters.Great Tits, with some annual variation, have been largely stable - 316 birds in winter 1999/2000, basically the same today. Same picture with Blue Tits, though even greater variation year to year, but 86 in 1999/2000, similar average wintering numbers today.I am certainly not saying 4G is not having negative effects in Greece or indeed anywhere else, but I would be interested why populations here do not seem to be crashing in the manner you report.</blockquote>
