Lisa, you are surely correct about the reddish appearing in the previous pic. Looks more like that whittled bark than leftover food.
Still just the one egg by noon today. About 9:00, there's a short view of HD gathering grasses from the pasture near the creek, then he brought a talon-load to the nest. Nice camera work from our intrepid, eagle-eyed cam ops!
HD has been on the nest the most today, and is calling for HM to take a turn, at 12:30.
