There's been a good deal of discussion nationally about consistently early reports on the "hummingbird maps." There's a definite disconnect between unusually early dates on these maps and the reports to eBird, which is gathering a huge amount of data from birders and has a verification process in place. The earliest eBird reports are consistently later, while some of the dates appearing on the "humminbird map" are extremely early. There's a good article on this gap and factors that might account for it in the most recent issue of North Ameican Birds. Apparently one of the stumbling blocks in sorting this out is difficulty in gaing access to any verification or documentation of the most extraordinary of the early "map" dates. Right now we're still a bit out in front of expected arrivals (to quote the article) "A century of bird study in New England has established that the vanguard of Ruby-throated Hummingbirds arrives in mid-April with the big push of migrants coming in late April and early May." Last spring the "map" reported 5 hummers in CT and Mass from March 14-23 without documentation. Birders reporting on eBird found their first ones on April 21 (CT) and April 24 (MA).
If you see an early one, make every effort to document it in some way.

On a whim,I checked the hummer migration site last nite ( http://www.learner.org/jnorth/maps/humm_ruby_spring2013.html )
and found reports of hummers in CT and RI. We were thinking it's way to early for the feeders to be out.
