Steve,
Looks like there is research being done on this issue--seems like just in
Alaska.
But the researchers ask for input and reports on beak deformities.
Looks like they are interested in the lower 48, too. Or at least they'll know
related researchers on this issue:

Hello birders,
Eight days ago in the Cub Run RECenter woods (Fairfax county), I saw something
odd about a Ruby-Crowned Kinglet. I could not see the deformity well, and
forgot about it.
But this morning I found another R-C Kinglet with the exact same appearance in
a park south of San Francisco. (I think this post is at most 50% extralimital,
maybe less!!)
Each bird looked as if it had a third black bill, sticking out at about 45
degrees, above the "real" upper bill. I dismissed the first one assuming it was
just something stuck to the bird's forehead. But this one today forms a pattern
about 2,500 miles across.
Any ideas what I was seeing?
