All I know is that the meeting will be held at the Heide Spa Hotel in Bad Düben (http://www.heidespa.de/) from 14-17 ...

Re: smithsonianus with GPS to Norway

I am a bit late with this, but I checked the flight path of this bird and it does not look quite right. The link has changed; the Google Earth file is now on http://www.mass.gov/eea/agencies/dcr/water-res-protection/watershed-mgmt/gull-study.html. If you look at the flight path and the data in Googl...

The underwing coverts are too pale for GBBG, the pattern on scapulars and (upper)wing coverts appears too thin/delicate, and the pattern on inner primaries is not too good either.
