I am not sure how fresh the meal was but when I checked around 5:45 there was a meal sitting on the ledge and nothing else...
Yes, Moonstar, you're right, there was a meal (bird) laying on the ledge already this morning, before Cade flew in, according to my husband. May have been a food drop that had been made very early in the morning by a parent.
Unless, of course, it was already there last night, which I hadn't noticed... Bird perched on the corner of the nestbox right now, sitting on "Cade's corner", so likely it's Cade!
We may see lots of flying around today, while it is overcast and not so hot and humid.
