Sold for craft purposes, they also make perfect bird nests. They are much more spacious than wicker baskets and can hold up to a dozen sleeping societies, or the biggest of clutches, comfortably. They are also better ventilated than nestboxes and emit enough light so even timid bird aren't fearful to enter them. They allow easy nest inspections if positioned properly, at least compared to wicker baskets. And they're cheap! 2 dollars for a 6 inch (great for bigger birds or to accommodate a whole flock), 1 dollar for a 4 inch (good for one pair or 4 - 5 societies) For small cavity nesters, just snip a few twigs to create a little hole, and allow them to fill it to their hearts' content with grass or newspaper. For bigger birds which like a more open environment, just pull enough of the twigs away to create more of a half-covered nestbowl, and it becomes a canary's dream home. I've found all of my birds except my Javas like these for both sleeping and nesting, the Javas get a nestbox instead only because they're so large.
