Quill was busy last night. Too late for the update, Quill was on the scale at 8:19 PM. I waited for him to get off and move to the bowl of formula. 
QuillInstead, he slipped off the scale and left. I suspect it was because of the gray fox that caused him to leave a night or two ago. After I poured 2 pounds of pecans onto the scale, it read 19 pounds. With him on it, it fluctuated between 66 and 66.5, so let's say it was 66.25, meaning he weighed about 47.25 with a presumably empty stomach. After he left, the scale read 18, so he ate a pound of pecans and left weighing about 48.25. He's gaining weight!
He wasn't done, though. He had more weight to gain. He was back briefly at 1:15 AM and again from 1:56 to 2:23 AM, 3:06 to 3:41 AM, and 3:48 to 4:05 AM, consuming 2 1/2 pounds of formula (5 cups) and another pound of pecans to leave the scale reading 17 pounds. I'm anxious to get another weight on him.
Encouraged by how much formula he ingested, I went overboard with 7 cups this morning. He hasn't been back yet, but we'll measure how much is left in the morning to see what his capacity might be. There are also a couple pounds of walnuts on the scale (out of pecans), some peanuts in the shell in the feeder, and some yogurt raisins--all put out after dark so the squirrels and blue jays don't take them. The trail cam will tell the story.
After an interview with Time Magazine this morning, I saw the story online this evening at http://time.com/4550059/bear-attack-montana-todd-orr/ . I panicked when I saw they quoted me as saying bears (black, grizzly, and polar combined) kill 6-12 people per year. Luckily, I could call back and say the right number for the combined killings is "a couple." I fortunately caught the author, who is changing it.
Thank you for all you do.
