Hi Laurie, this is not a bird’s nest. This is most likely a fungus/slime mold in the genus “Reticularia.” They often grown on decaying wood, and can change a lot within even just a few hours. If you check the google images for “Reticularia” you’ll see that some have this same “plastic bag” look to them, which indicates they are a bit further along in their fruiting cycle. Thanks for sharing!
