I went out to take another quick look at the nest in the early afternoon. It was 95 degrees and I have problems with heat, so I was only going to take a teeny tiny peek. However, I just couldn't help myself, and had to stay for a few minutes and snap pics.

Mom seemed to be up over the nest (shading it?), rather than actually sitting on the eggs. It was certainly warm enough out there for the eggs, without any additional body heat. Does anyone know what the hummers actually do in this instance, as I am only guessing.
