Movements and wintering areas of breeding age Thick-billed Murre Uria lomvia from two colonies in Nunavut, Canada

first_imgThe non-breeding movements of marine birds were poorly known until recently, but this information is essential to understanding the risk to different geographical populations from events on the wintering grounds. We tracked the migration routes and wintering areas of Thick-billed Murre Uria lomvia from two breeding colonies in eastern Canada: Coats Island in northern Hudson Bay and The Minarets, Baffin Island, during the period August 2007-May 2008 using geolocation loggers. Birds from The Minarets moved south rapidly post-breeding and wintered principally off Newfoundland and southern Labrador, or between Newfoundland and southern Greenland, remaining south of 55A degrees N until at least the spring equinox. Those from Coats Island remained in Hudson Bay until at least mid-November, after which they moved rapidly through Hudson Strait to winter in southern Davis Strait and the northern Labrador Sea, mostly north of 55A degrees N. Many individuals stayed throughout the winter in areas of heavy ice cover. Adults from the two colonies appear to be completely segregated in winter and those from Coats Island probably did not enter the area of the winter hunt in Newfoundland. Unexpectedly, some birds from The Minarets wintered in waters beyond the continental slope and outside the distribution of pack ice, demonstrating that particular individuals can be wholly pelagic throughout the winter. Coats Island birds returned through Hudson Strait as soon as open water areas became available in spring. Their sojourn in Hudson Bay coincided very closely with the occurrence of areas with < 90% ice cover. In spite of the relatively large error in positions obtained from geolocation loggers, our results demonstrated the value of these devices by uncovering a number of previously unknown aspects of Thick-billed Murre non-breeding ecology in the Northwest Atlantic. Comparison of the non-breeding ecology based on SST experienced in winter show that the winter niche is broader than hitherto assumed, demonstrating that separate populations may experience different selection in the face of climate change.last_img read more

Luke Messer’s answers to more than an hour of tough questions on national issues,” said Grassroots Conservatives leader Robert Hall.  “We liked that he sponsored a bill to get rid of a loophole that illegal immigrants use to receive tax credits. And he voted against the $1 trillion Omnibus spending bill in May 2017 that failed to cut domestic spending as proposed by the Trump administration. I feel he is a solid conservative and has the best chance to replace Joe Donnelly as U.S. Senator.”The straw poll was conducted using a point system in which each YES vote was 1 point and each NO vote was -1 point.Also in December, Messer led his primary opponents in an IndyPolitics poll on the Indiana U.S. Senate race.FacebookTwitterCopy LinkEmailShare Luke Messer won a recent U.S. Senate straw poll conducted by the Grassroots Conservatives in Bloomington, Indiana.Messer led all six primary candidates by an eight-point advantage in the Dec. 28th poll. Below are the results of the straw poll released by the Grassroots Conservatives this week:last_img read more
