The applications have stretched into conservation, working with the Vermont Natural Resource Conservation Service (USDA) to create a successful and broadly deployed haying program for intensive dairy farms that balances both bird and farmer needs.<\/p>\n\n\n\n<p>Today, the project, known as the Bobolink Odyssey, is a long-term life-cycle study. In this study system, nestlings of both species and sexes return to breed at a very high rate on or very near the fields they were born.&nbsp; This behavior allows us to track lineages of birds, a highly unique opportunity for migratory songbirds. Our goal is to follow these lineages for as long as they last, and to know everything we can about them: number of offspring produced, annual survival, dispersal within the landscape, mate selection, timing and location of nesting, and perhaps most fantastic, migration.&nbsp; We continue to track Bobolinks and Savannah Sparrows with geolocators and other mind-blowing technologies like satellite tags and nanotag.<\/p>\n\n\n\n<p>Many project collaborators including: <a href=\"https:\/\/web.archive.org\/web\/20160303070432\/http:\/www.uvm.edu\/rsenr\/faculty-staff\/allan-strong\">Allan Strong,&nbsp;<\/a>University of Vermont, <a href=\"https:\/\/www.une.edu\/people\/steven-e-travis\">Steve Travis<\/a>, University of New England, <a href=\"https:\/\/web.archive.org\/web\/20160303070432\/http:\/www.nrcs.usda.gov\/wps\/portal\/nrcs\/detail\/vt\/contact\/?cid=nrcs142p2_010675\">Toby Alexander<\/a>, NRCS Vermont, <a href=\"http:\/\/www.kovachlab.com\/\">Adrienne Kovach<\/a>, University of New Hampshire, <a href=\"https:\/\/www.umsl.edu\/~parkerp\/ParkerLab.html\">Patty Parker<\/a>, University of Missouri StL, and <a href=\"https:\/\/web.archive.org\/web\/20160303070432\/http:\/vtecostudies.org\/about-us\/staff\/rosalind-renfrew\/\">Roz Renfrew<\/a>. &nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"927\" height=\"1024\" src=\"https:\/\/sites.une.edu\/perlutlab\/wp-content\/uploads\/sites\/9\/2019\/04\/migration-map-927x1024.jpg\" alt=\"\" class=\"wp-image-109\" srcset=\"https:\/\/sites.une.edu\/perlutlab\/wp-content\/uploads\/sites\/9\/2019\/04\/migration-map-927x1024.jpg 927w, https:\/\/sites.une.edu\/perlutlab\/wp-content\/uploads\/sites\/9\/2019\/04\/migration-map-272x300.jpg 272w, https:\/\/sites.une.edu\/perlutlab\/wp-content\/uploads\/sites\/9\/2019\/04\/migration-map-768x848.jpg 768w, https:\/\/sites.une.edu\/perlutlab\/wp-content\/uploads\/sites\/9\/2019\/04\/migration-map.jpg 1015w\" sizes=\"auto, (max-width: 927px) 100vw, 927px\" \/><figcaption class=\"wp-element-caption\">Migration map for 17 Bobolinks that nest in Shelburne, VT and winter in Bolivia, Paraguay or Argentina. <\/figcaption><\/figure>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This project started in 2002 to answer a fairly simple question\u2014how do grassland songbirds respond to &hellip;<\/p>\n","protected":false},"author":11,"featured_media":107,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"folder":[],"class_list":["post-105","page","type-page","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 -
