However a much higher concentration of birds were found above the island. The authors suggest that this is because the birds rely on the islands for landmarks or as a place to rest in an emergency.<\/span><\/p>\n<p><a href=\"http:\/\/canadianfieldnaturalist.ca\/index.php\/cfn\/article\/view\/1577\" target=\"_blank\"><span style=\"text-decoration: underline;\"><span>Original research paper<\/span><\/span><\/a>\u00a0published in the <em>Canadian Field-Naturalist\u00a0<\/em>on\u00a0<strong>July 7, 2014<\/strong>.<\/p>\n<p><span style=\"text-decoration: underline;\"><span><strong>Names and affiliations of selected\u00a0authors<\/strong><\/span><\/span><\/p>\n<h4><span style=\"color: #000000;\">Daniel Mennill, University of Windsor, Ontario<\/span><\/h4>\n","protected":false},"excerpt":{"rendered":"<p>New audio recordings confirm that Lake Erie is not a barrier to bird migration, but that birds pick their routes so as to stay above islands if possible.
