A = microphone cannot withstand too much of the rain, wind, and snow that = comes with this time of year. =20 I have occasionally recorded vagrants in the late fall. If = hurricane-driven vagrants are any example, birds will try to go = =E2=80=9Cback home=E2=80=9D or to their intended destination. I would = not assume that our recent rare warblers, vireos, sparrows, and = hummingbirds have succumbed when they disappear but have, hopefully, = built up some fat reserves and are continuing their journey. =20 John =20 From: naturens-owner@chebucto.ns.ca = [mailto:naturens-owner@chebucto.ns.ca] On Behalf Of Carmel Smith Sent: November-03-16 09:21 To: naturens@chebucto.ns.ca Subject: Re: [NatureNS] Nocturnal Migration for the 4th Week of October =20 Thanks John, and Lance, for adding to the knowledge base on migration. = It's an amazing phenomenon, and the more we know the better.=20 One last question occurs to me, hearing the recent reports of all the = vagrants, including not a few rare-for-this-area warblers:=20 =20 Do any of these make their way "back home?"=20 =20 And, John, when do you make your last Nocturnal Migration report?=20 =20 These misdirected birds do get observed by birders over a period of = time, and often stay where they landed until suddenly they are no longer = there, presumably perished through cold/lack of food or from predators. = A few, particularly seed-eaters, can make it through at feeders. But it does occur to me to ask now if there is any nocturnal monitoring = going on late into the Fall, and if some of these don't find their way = to a more forgiving climate before the snow flies? Would a lone bird = leave and strike out across the water so late in the year? Would it call = as they do in groups? Thanks for your patience in indulging my curiosity! Carmel Smith Midville Branch, NS =20 =20 On Wednesday, November 2, 2016 12:00 PM, "Laviolette, Lance" < = <mailto:lance.laviolette@lmco.com> lance.laviolette@lmco.com> wrote: =20 Hi Carmel and others interested in bird migration in Nova Scotia, I can add a bit to John=E2=80=99s excellent information. As John has written, bird migration has been shown to be weather related = and sporadic. In the fall the biggest peaks usually correspond to the = passage of a cold front and winds from the northwest. There are usually = a small to moderate number of pulses of migration through the season. As the season progresses the species that the peaks are composed of = change. The data that John sent out to us illustrate this change through = the migration season very nicely. Here are his top five species during = the weeks he detected peaks this year: 4th Week of August American Redstart Common Yellowthroat Northern Parula Black-and-White Warbler Magnolia Warbler 2nd Week of September Northern Parula Common Yellowthroat Blackpoll Warbler Black-throated Green Warbler Magnolia Warbler 4th Week of September Common Yellowthroat Savannah Sparrow White-throated Sparrow Lincoln's/Swamp Sparrow Yellow-rumped Warbler Warblers dominate in the first part of the season and for the most part, = sparrows dominate later. This is a similar result to what other studies = have found and what Nova Scotia birders are very familiar with. To fill in more of the picture, flycatchers move through mid to late = August, Blackpoll and Palm Warblers move in late September and kinglets, = chickadees, Dark-eyed Juncos, Blue Jays and American Robin movements = peak in October. There will of course be some shifting of the timing depending on if = you=E2=80=99re located up where Fritz is in Cape Breton or where Alix is = in Pubnico.
