Hi Keith and all

I think in spring the Migration is not over the Atlantic: =46rom South Ameri=
ca it is over the western Caribbean overflying most of the islands -although=
 more seen on Bahamas then elsewhere. The birds move through North America t=
hrough Florida with majority moving north up the US east coast and through O=
hio and Mississippi Valleys and those that come here work their way up throu=
gh the eastern states eventually to Maritimes. =20

In the fall as Lance says they make the crossing over the Atlantic to South A=
merica.  My info is from Dunn and Garrett "Warblers".  There are a good numb=
er of people in the Maritimes working on Blackpoll Migration who may be able=
 to explain sprin Migration better than what I have outlined.=20

A search on ebird observations for the current year shows progress to date f=
or 2017:

cur

Interesting the birds don't seem to go west of Northern Panama and seem to c=
ross over the Caribbean off Nicaragua. When we birded in Costa Rica we had a=
n excellent guide Steve Easley who on that trip saw his first Costa Rican Bl=
ackpoll and this set off a rare bird alert for birders in Costa Rica.=20

Cheers
Ken
