This a link about the articles, reports, papers and reports with serious scientific reports along with reports and latest survey reports. Published monthly you also get access to all post British Birds Journals online going back to the first edition in 1907. It is not cheap to subscribe. But in my opinion it is best monthly journal as well the other well known monthly bird magazines.
