Thanks John, and Lance, for adding to the knowledge base on migration. It's=
an amazing phenomenon, and the more we know the better.=C2=A0
One last question occurs to me, hearing the recent reports of all the vagra=
nts, including not a few rare-for-this-area warblers:=C2=A0
Do any of these make their way "back home?"=C2=A0
And, John, when do you make your last Nocturnal Migration report?=C2=A0
These misdirected birds do get observed by birders over a period of time, a=
nd often stay where they landed until suddenly they are no longer there, pr=
esumably perished through cold/lack of food or from predators. A few, parti=
cularly seed-eaters, can make it through at feeders.
But it does occur to me to ask now if there is any nocturnal monitoring goi=
ng on late into the Fall, and if some of these don't find their way to a mo=
re forgiving climate before the snow flies? Would a lone bird leave and str=
ike out across the water so late in the year? Would it call as they do in g=
roups?
Thanks for your patience in indulging my curiosity!

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 an=
d 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 migra=
tion 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, sp=
arrows 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, chickade=
es, Dark-eyed Juncos, Blue Jays and American Robin movements peak in Octobe=
r.
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 Pubni=
co.
All the best,
Lance
