Summary: | This is an Accepted Manuscript of an article published by Taylor & Francis in "Ringing and Migration". Published version available at http://dx.doi.org/10.1080/03078698.2016.1190610. Arctic Terns Sterna paradisaea have a record-long migration between their breeding grounds in the Arctic and wintering areas in the Antarctic. Nevertheless, return dtaes to north Norway were remarkably constant over a 35-y period (1981-2015), arriving in Troms within a 13-d time window in mid to late May. Since 1993, arrival dates have advanced by about four days. No relationships were found between arrival dates and large-scale weather proxies such as the North Atlantic Oscillation or sea temperatures, but when terns were approaching Troms, headwinds tended to delay arrivals whereas tailwinds advanced them. |
