Each year Turus Mara transport a bunch of enthusiastic scientists collectively known as TIARG - clumsily short for Treshnish Isles Auk Ringing Group, to camp on Lunga for the 3rd week in June.
They count and ring as many seabirds as they can manage in whatever varied weather conditions the Atlantic happens to throw at them. From this dedicated effort a 30 page statistical report is produced and filed to the Seabird Colony Register and the National Ringing Database (British Trust for Ornithology).
Real Serious Students of Birdlife can therefore find as much detail as floats their boat from these sources.
Below are the most recent Treshnish Isles Auk Ringing Group Reports as posted on the Hebridean Trust Website.
