The whole time I was there, the only thing I saw was an adult fly from the north to the horizontal branch above the nest. He/she did not bring any food. After about 6 minutes, the eagle flew away without visiting the nest. I did not hear any calling from the eaglet or the adult. It did rain on and off while I was there, so hopefully the eaglet was just trying to stay dry.
I really hope someone will see the eaglet tomorrow.
