After Šime and Ugo, another three Mediterranean Shags which were tagged with GPS loggers at Slovenian sea in summers 2013 and 2014, migrated to Croatia.
Mihi, Ante and Roko migrated to different parts of the Adriatic sea along the Croatian coast between mid-October and the end of December. The youngest among them, second-year Mihi, migrated the longest distance: it stopped merely 30 km before the town of Split and thus travelled almost 120 km further than Šime, the Shag which migrated in 2012 to the island of Molat. Mihi moved southwards already twice before its migration to Dalmatia: in February last year when it made a one week trip to coastal waters between the towns of Poreč and Rovinj, and then just a few days before the big leap, when it visited the same place for less than two days.
Our old acquaintance Ante migrated to its birth place on the Oruda island near Lošinj where it probably returned before. Adult Shags are very faithful to their breeding grounds. Ante will turn 5 in spring, and it has been sexually mature for two to three years.
Roko migrated to Kvarner, too. It travelled for four days to the destination and is still there: its GPS logger has been sending the data from the Unije island since 22. December. Unfortunatelly we already lost the signal from the other four.
