Sti= ll they are far behind many of our other breeding warblers. Though not many= Bay-breasted, Canada or Tennessee approaching yet either. Of the ones I ch= ecked, Mourning are the farthest behind with only 1 report in the US so far= .

The birds move through North America = through Florida with majority moving north up the US east coast and through= Ohio and Mississippi Valleys and those that come here work their way up th= rough the eastern states eventually to Maritimes. In the fall as Lance says they make the crossing over the Atlantic to South= America. My info is from Dunn and Garrett "Warblers". There are a good n= umber of people in the Maritimes working on Blackpoll Migration who may be = able to explain sprin Migration better than what I have outlined. A search on ebird observations for the current year shows progress to date = for 2017: http://ebird.org/ebird/canada/map/bkpwar?neg=3Dtrue&env.minX=3D-153.4758045= 7279912&env.minY=3D10.523013815308705&env.maxX=3D18.78982042720088&env.maxY= =3D73.13533496238743&zh=3Dtrue&gp=3Dfalse&ev=3DZ&mr=3D3-5&bmo=3D3&emo=3D5&y= r=3Dcur Interesting the birds don't seem to go west of Northern Panama and seem to = cross over the Caribbean off Nicaragua. When we birded in Costa Rica we had= an excellent guide Steve Easley who on that trip saw his first Costa Rican= Blackpoll and this set off a rare bird alert for birders in Costa Rica.
