"Thank you very much for reporting this sighting! Y-17T is indeed one of our birds. It was ringed, with 311 conspecifics, in the colony “Utopia”, Texel, The Netherlands, on 27 June 2015, and is the fourth of this year’s chicks to be reported from the greater Channel area. We prepared a map (yesterday, so your bird is not on it yet) of all sighting so far. Please have a look at:
by clicking on the symbols, you will get details on ring numbers and dates (week numbers).
It is wonderful when project leaders reply with such a wealth of interesting information!

When ringed, it was a very average-sized chick, compared to all the others: its measurements and body mass were placed centrally in the cloud of data points. I guess that “being average” means exactly nothing!
