​Thanks to everyone who has offered theories to my query regarding disappeared hummingbirds.  This list is so helpful and heart-warming for amateurs like me. 

However, today, while visiting a farm on Tucker Hill Road in Thetford, I learned that they had half-a-dozen hummers zooming around their feeder until about a week ago.  Now, there are none there either.

I have never had this happen before, nor had she.  Troubling...

Hope there is not a disease going around.
