That’s very frustrating re. the hog house survey – isn’t that always the way!
It can get a bit confusing with male and female hogs, especially as it sometimes seems as if they teleport. You look away for a second and there is a completely different hog there in the same position when you look back.
It’s really good the hog is still using your hog house. I wonder if he is planning on hibernating, especially as he was closing ‘the door’ after himself. Maybe he was going to hibernate and then the female turned up and distracted him? I understand the summer nests are less elaborate.
It is interesting that they no longer seem that interested in each other. The remaining male here is beginning to get less and less interested in the females and one of the females just runs off if she sees him coming. She must be quite an old hog now, and perhaps realises that it is too late in the year to be getting pregnant now.
