Webworm Nest at Tx Black Walnut Tree

At a city park in June, I noticed a conical item high on a Texas Black Walnut tree. I took some pix and a zoom-in/out video. Although details weren't great, the item looked "aerated". Returned with someone else who brought a monopod and higher-resolution camera. Over about a week, posted some images and zoom-out video to LinkedIn for gathering opinions on what the item could be.
