Hi John,
It's unfortunate that the winds forecast necessitated the take-down of the =
monitoring equipment! It would be amazing to find out more about how the fa=
llout birds leave. Questions such as: When they leave, answering questions =
of how long they hang on in the province after landing; What routes they ta=
ke to leave; How they leave--whether there is a mass outflow or do they jus=
t straggle along as they leave?=C2=A0
I also wonder how the familiarity of the territory affects how they leave? =
In other words, we have no reason to believe--as far as I can tell--that th=
e birds which have ended up here have ever been to this area. Some of them =
perhaps, but the fact they end up here in this situation wouldn't have any =
bearing on where these individuals have their breeding grounds. Does famili=
arity with the territory influence how swiftly they can recover and find th=
eir way back on a track to their normal wintering grounds? The Magnolias in=
your last report, are they back on track quickly because they are individu=
als who were breeding here? Were they swept in from a nearer area than all =
the catbirds, tanagers, grosbeaks, etc.?
All questions I ponder... and have to say, your last reports gave a glimpse=
...but how much more we could learn if the stations were still up and we co=
uld see more of their migration, since they are still here. The reports are=
still coming in, and as people move away from the hotspots and check other=
areas, they are discovering more birds in pockets where they find suitable=
cover and food. These areas are not always right at the coast, though ofte=
n within several km of the ocean. I hope the data being accumulated will be=
examined for these facts as well (where the birds found a spot to recover =
and how they move out from there--ebird being a major data source for this)=
. Though the lack of birders--except for those who frequent the hotspots an=
d check out areas already reported to harbour vagrants--will mean many are =
missed. At least until they end up in one of the funnels in the Southwest; =
hopefully the diligence of birders in the exit areas will give a good snaps=
hot of the departure patterns.=C2=A0
=C2=A0
Which brings me back to my original thought--how awesome it would be to be =
able to have nocturnal migration records of their movements!=C2=A0
John, are there any stations still in operation?
thanks again for your dedicated work!

Hi All,
The last report for this year=E2=80=99s autumn nocturnal migration in Yarmo=
uth County is posted on my webpage at the following links.
=C2=A0
Carleton: http://johnfkearney.com/Carleton_Yarmouth_County_2017.html
=C2=A0
Cape Forchu: http://johnfkearney.com/Cape_Forchu_Yarmouth_County_2017.html
=C2=A0
Although migration volume was low this week, the report provides some data =
on the historic fallout of 26-30 October from a nocturnal perspective.
=C2=A0
