On the 9th of September 2007 during a full-day birdwatching tour through madeira nature with Madeira Wind Birds, one Dunlin of the subspecies alpina was observed in Ribeira da Janela, Seixal. The observers were Helen & Paul Colto from UK, Catarina & Hugo from Madeira Wind Birds. The main characteristics that allow the observers to identify it as the ssp alpina of a Dunlin were its longer bill, its clearer head and breast with the distinct black belly and the bright rufous colour near the wing.
