Boise, ID. My husband and I heard a big crash at 5am,like something had fallen off the roof. He found this feather mass on the ground just now. Said it feels like it has a membrane inside of it? This is in our side yard, about 4 feet of gravel between a fence and the side of the house.

Found this from 5 years ago, looks like someone found something similar. The creepy factor is someone talking about "death crowns" or "Angel balls" as folklore of a ball of feathers left when someone dies.

However in my research I may have found a probable explanation. When predatory birds (hawks) eat other birds they often first strip them of feathers. This usually means pulling off swaths of feathers from the breast of the prey bird. And with it can come the skin of the bird. This is tossed aside. A section of these feathers under the right conditions can form into a ball as the skin desiccates and pulls inward until you end up with a ball of feathers with skin in the center.

Anyway, that is what I found. Here is that old reddit post: https://www.reddit.com/r/whatisthisthing/comments/rjq11/ball_of_fluff_covered_in_feathers_found_in_the/
