A few of us noted on the first morning that they were busily grabbing grubs/mealworms from underneath The Little Yellow Tree.
This reminded me of a Julie Zickefoose essay where she talked about feeding bluebirds and making them sick (as I remembered it) so I looked it up. I couldn't find the original essay, as it's in some book I must have given away, but I did find this:
I only bring this up because a friend and I joked about feeding them, but it doesn't seem unlikely that someone might try, which reminds me of a wintering vivid niltava (which isn't too dissimilar from a make bluebird) in Taiwan years ago that, when spring time came, didn't migrate back to wherever he was from because he had apparently gotten too attached to all the free mealworms the photographers fed him every day (or he had gotten too fat to make the flight).
Food for thought.
