Crop - below the neck and you will see a blug on the breast at the top.
After work I met Janice and Doug to watch the red tails. The oldest one gave us a nice show on the branch. We could also see th other 2 eyas futhur in the nest. Dad was sitting on top of the condo then government building. Female brought in food prior to Janice arriving.
The most interesting thing last night was the size of crop on the oldest eyas (crop is where the food when they eat it goes) and last night it seemed to get bigger and bigger. We figured that is why he was so quiet. Will post some shots later.
