I never intended to equate the probable frequency of finding Broad-winged 
Hawks and Cape May Warblers here in winter. My argument was that, since a 
few individuals of both species winter in the southern U.S., it should not 
be impossible to find either straying (or lingering) farther north on very 
rare occaisions. Since Cape May has been found in Missouri in winter 
casually,  why not Broad-winged Hawk once in a blue moon?

Of the two species, Broad-wing is somewhat more likely than Cape May to be 
found in the U.S. in winter. A very few individuals of  both species winter 
on the southern tip of Florida, but Broad-wing is found a little farther 
north than Cape May. A very small number of Broad-wings also winter in 
southern Louisiana, and perhaps in Texas.

It is possible that Broad-winged Hawk is actually more frequent than Cape 
May Warbler as far north as Missouri, but that, for good reasons,  fewer 
records of it are accepted. Most Cape Mays found in winter appear at 
feeders, where they can be closely and often repeatedly observed (and 
perhaps photographed) by many observers. If a Broad-wing were to show up 
here, it would normally be farther from the observer(s); only one or two 
observers would be likely to see it, and it  would probably be seen on only 
one occaision.

Given unequal opportunities to make good IDs of Broad-winged Hawks and 
built-in skepticism about winter Broad-wing reports, there is probably no 
way to compare how often the two species actually show up here in winter.

I concur with Dave's suggestion that, since mistaken ID's of Broad-wing are 
so common in  winter, MBRC probably should require a good photo before 
listing it as a winter vagrant.
