Any chance of a closer view? Wasps make hives in that shape, and some are very intricate, but that looks more structured than any of the pictures I have seen. Some species of birds make similar shaped nests and are more into "weaving" in the fashion of your pic. The bottom of the object in your picture seems to be "sprouting" bits of whatever material it is made of.
The last pic looks like the "nest" is woven around a small branch...the thing that keeps stumping me is the almost perfect symmetry and the color...it really looks like a woven gourd. I have spent a few hours looking at wasp nests and images of "pendulous" bird nests as there are a number of birds in your area that make nests of that sort, just not that "fine"
Here is the contact info for Cornell University dept of Ornithology. They are the "bird folks" and I think if you e-mailed them the pics, they could confirm if this is indeed a bird's nest or not.
Thank you, themoonhowl, for your suggestion to contact Cornell! Here is their surprising reply:
I posted your photos here at the Cornell Lab of Ornithology to draw on the wide expertise we have here. Not surprisingly, I got back a wide range of responses. The consensus, however, says that this is actually a pine cone. Hereís a link to photos of one pine cone from the UK:
