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: http://ebird.org/ebird/canada/map/bkpwar?neg=3Dtrue&env.minX=3D-153.47580457= 279912&env.minY=3D10.523013815308705&env.maxX=3D18.78982042720088&env.maxY=3D= 73.13533496238743&zh=3Dtrue&gp=3Dfalse&ev=3DZ&mr=3D3-5&bmo=3D3&emo=3D5&yr=3D= 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 Sent from my iPad > On Apr 25, 2017, at 11:42 AM, Laviolette, Lance <lance.laviolette@lmco.com= > wrote: >=20 > Hi Keith, > =20 > In the fall Blackpoll Warblers fly from the northwest across Nova Scotia a= nd out over the Atlantic Ocean to the southeast.
