Prey Species Inventory

I did a bit of looking at my notes. Not sure I have this totally right yet, but I have the beginnings of a prey chart for this year. Someinteresting stuff on there! When the chicks came out, I noticed far fewer prey accounts. Herc and Max just didn’t make as many trips to the nestand I was too busy, at times, chasing down chicks to be able to watch what they were bringing into the nest. So, the last part seems a bit sparse. Anyway, here’s what I have:
