Br\u00fcnnich&#8217;s guillemot populations in the North Atlantic Ocean and Barents Sea are decreasing, and the species is facing several threats: oil spills, bycatch, hunting and oceanic change influencing prey availability are the most important ones. The methods used in mapping migration routes for birds have developed extensively in the recent decades, and traditional bird bands are very often supplemented with geolocation or geo light sensors, so-called GLS tags. An international group of researchers have compiled their data from different GLS studies on Br\u00fcnnich&#8217;s guillemots breeding in the North Atlantic, the Barents Sea and North America in order to build a complete overview of the migration paths for the different populations of the species.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Read the article:<\/h4>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"http:\/\/dx.doi.org\/10.1016\/j.biocon.2016.05.011\" target=\"_blank\" rel=\"noreferrer noopener\">Migration and wintering of a declining seabird, the thick-billed murre&nbsp;<em>Uria lomvia<\/em>, on an ocean basin scale: Conservation implications<\/a><\/li><\/ul>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr.jpeg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"769\" src=\"https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr-1024x769.jpeg\" alt=\"\" class=\"wp-image-3713\" srcset=\"https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr-1024x769.jpeg 1024w, https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr-300x225.jpeg 300w, https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr-768x577.jpeg 768w, https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr.jpeg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption><strong>The father accompanies the Br\u00fcnnich&#8217;s guillemot chick on their way towards the wintering areas.<\/strong><br>Photo: Tone Kristin Reiertsen<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p class=\"has-sizing-medium\">The results form the work shows that the most important wintering areas for Br\u00fcnnich&#8217;s guillemots are off Newfoundland and Labrador, along the west coast of Greenland and around Iceland. There was strong correspondence between wintering area and breeding population status: stable populations breeding in Canada and Northwest Greenland wintered mainly off Canada, whereas declining populations from Svalbard and Iceland wintered mainly off West Greenland and around Iceland. In some of the populations, there was a clear tendency for the females to leave the breeding grounds earlier than the males, who stay with the chick in the first period after fledging. The study corroborates earlier discoveries and emphasizes the importance of a coordinated international management effort for migrating seabirds.<\/p>\n\n\n\n<p class=\"has-sizing-medium\">Contact person:&nbsp;<a href=\"http:\/\/www.seapop.no\/profiles\/hallvard-strom\">Hallvard Str\u00f8m<\/a>, Norwegian Polar Institute<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A recent study now provides an overview of the migration routes and wintering areas of &hellip; <\/p>\n<p class=\"read-more-link\"><a href=\"https:\/\/seapop.no\/en\/2016\/08\/wintering-areas-are-important\/\">Les videre<span class=\"screen-reader-text\"> \u00abWintering areas are important\u00bb<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":3713,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_uag_custom_page_level_css":"","footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-3712","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-uncategorized"},"acf":[],"uagb_featured_image_src":{"full":["https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr.jpeg",1200,901,false],"thumbnail":["https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr-150x150.jpeg",150,150,true],"medium":["https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr-300x225.jpeg",300,225,true],"medium_large":["https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr-768x577.jpeg",768,577,true],"large":["https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr-1024x769.jpeg",1024,769,true],"1536x1536":["https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr.jpeg",1200,901,false],"2048x2048":["https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr.jpeg",1200,901,false],"default":["https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr-1200x700.jpeg",1200,700,true],"square":["https:\/\/seapop.no\/wp-content\/uploads\/2021\/02\/polarlomvi-med-unge-tkr-400x400.jpeg",400,400,true]},"uagb_author_info":{"display_name":"Erlend Lorentzen","author_link":"https:\/\/seapop.no\/en\/author\/erlend\/"},"uagb_comment_info":0,"uagb_excerpt":"A recent study now provides an overview of the migration routes and wintering areas of &hellip; Les videre \u00abWintering areas are important\u00bb","_links":{"self":[{"href":"https:\/\/seapop.no\/en\/wp-json\/wp\/v2\/posts\/3712","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/seapop.no\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/seapop.no\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/seapop.no\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/seapop.no\/en\/wp-json\/wp\/v2\/comments?post=3712"}],"version-history":[{"count":3,"href":"https:\/\/seapop.no\/en\/wp-json\/wp\/v2\/posts\/3712\/revisions"}],"predecessor-version":[{"id":4325,"href":"https:\/\/seapop.no\/en\/wp-json\/wp\/v2\/posts\/3712\/revisions\/4325"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/seapop.no\/en\/wp-json\/wp\/v2\/media\/3713"}],"wp:attachment":[{"href":"https:\/\/seapop.no\/en\/wp-json\/wp\/v2\/media?parent=3712"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/seapop.no\/en\/wp-json\/wp\/v2\/categories?post=3712"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/seapop.no\/en\/wp-json\/wp\/v2\/tags?post=3712"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
