Last night I went home at 7:44 PM after putting one final scoop out. Quill got on the feeder at 8:23 PM and may have gotten here sooner to eat walnuts on the scale. 
Quill at 8:54pm Nov 4, 2016The scale doesn't show on the trail cam. He stayed until 8:54 PM.
He was back on the feeder eating formula from 12:39 AM to 1:17 AM. Shortly a gray fox was on the feeder, which might be why cautious Quill left. He wasn't done. He probably knew there was some of the 7 cups (3 1/2 pounds) of formula left. He came back in during daylight at 7:55 AM. At 8 AM, the trail cam shows him looking down the driveway, which is exactly when I was driving in.
Quill at 8:00am Nov 5, 2016He'd eaten the entire 3 1/2 pounds of formula plus 2 pounds of walnuts. That's a lot for a 48-pound bear. Starting out at 32, he has gained half his weight--probably mostly in fat for fuel.
I can't tell if there is any dirt on him from a den. I'd like a good look at him in daylight. But in the meantime, I ordered a big dog house that is almost 3 feet wide and 4 feet long. It shipped today and will be here Thursday. 
Red squirrelI want to put it along the path where he leaves, put some straw by it, and see if he uses it. I'm probably wasting money. I don't know of something like that ever working. But maybe a right-sized plastic dog house stuffed with straw would get a second look. We can only try.
Also, I'm doubting myself on my sexual identification of him. The fleeting look at the bump might not have been far enough up on his belly and could have been the vulva. I want another look. I'll keep saying 'he' until I know to change.
Female pine martenI wish we had our old setup on the scale. It used to be that when an animal got on it, the computer would give a sound, a camera would start taking a picture every 10 seconds, and the computer would record the correct weight. But the camera got water in it, the program has a glitch, and the technical people are down in the Twin Cities. So I check the monitor downstairs and read it directly while the bear is on the scale. That allows me to see how the amount of food on the scale changes, too, so it's not all bad.
Pine marten femaleMidday, the female pine marten came for some date mash and then looked to see what I was up to as I snapped a portrait. About that time, a red squirrel was resting in good light on a forked, dead branch high in a white pine.
The temperature got up in the 60's after a 33°F start for little Quill.
Thank you for all you do.
