Nice seng pics. Also that big mess of branches and leaves in that tree top looks like some kind of primate nest to me when I first saw it. I am not a primate expert by any means but have seen them many times on different TV programs. I Googled it to see if there were any examples that looked close to your pics.
What do you think? Maybe somebody's monkey got loose and is living in that woods. Who knows.
I am with you Maya. Winters sure are tough there and it would be difficult to say the least for a primate to survive but who knows. I know there are a lot of people that have different Primates as pets and sometimes they get loose and never do come back. Who knows it maybe a baby Big Foot nest. lol . I have been in the woods most of my life. I have seen gigantic eagle nest, Squirrel nest and hawk nest and have never seen anything like that before.
It sure appears to be constructed and woven verses some branch(s) that got blow down from another tree and happened to land there.
I am sticking with my primate theory. It sure looks like a primate nest to me. Kind of far fetched though to say the least. It would be interesting to show that pic to a true primate expert to see what they say. If that nest is obtainable without too much trouble, I would love to see some pics perhaps with a zoom lens.
Maybe you could forward the pic to BFRO and see what they say.
