In June, Google Scholar released its journal metrics for 2014 (actually June 2013 - June 2014): http://googlescholar...s-released.html
You can drill down and they actually have a category for birds. Interesting to see the results: http://scholar.googl...en&vq=bio_birds
Also interesting, you can click on each journal's h5 index to see the most-cited papers from the past 5 years. Lots of really interesting papers on those lists. Apparently others think so too!
