Index of Subjects <html> <body> <font size=3>A very good guess I would say, Nancy. However Gannets are distinct from the others mentioned in that they dive from the air. I wonder how they ready themselves (or maybe they don't have to considering their short time under water?).<br> Angus<br><br> At 10:10 AM 2/15/2013, you wrote:<br> <blockquote type=cite class=cite cite="">I wonder if the loons, mergansers, razorbills etc are not scoping the water but rather immersing their nares (nostrils) in order to initiate the "diving response" to allow efficient use of oxygen while diving as outlned in this article (<a href="http://www.ducks.org/conservation/waterfowl-biology/diving-ducks-into-the-deep/page2"> http://www.ducks.org/conservation/waterfowl-biology/diving-ducks-into-the-deep/page2</a> ).<br><br> Cormorants, Gannets etc (Order Pelecaniformes) do not have external nostrils and would have no need to dip their heads in water to ready themselves for diving.<br><br> Just a guess.<br><br> Nancy<br> <br> </font><font size=2><b>From:</b> "iamclar@dal.ca" <iamclar@dal.ca><br> <b>To:</b> naturens@chebucto.ns.ca <br> <b>Sent:</b> Thursday, February 14, 2013 9:31:51 AM<br> <b>Subject:</b> [NatureNS] Razorbill inner St. Margarets Bay, HRM<br> </font><font size=3><br> All:<br><br> Paul Brodie phoned yesterday to report a Razorbill foraging off his house on Boutiliers Pt., inner St. Margarets Bay - first he's seen there in decades.
