Description
This box had been used by eastern bluebirds in the breeding season 2019. At the end of September it was cleaned, taken down for repairs and remounted in late October. Several days later this big nest was found inside. Can someone suggest what species would have built this nest so late in the fall? House sparrows perhaps?

Whose Nest?
I think either a house sparrow or wren…. not sure.
