Moss Bird Nest? Wisconsin, USA

Someone is starting a moss nest in one of our bluebird boxes. Any ideas what it could be? My googling is failing me.

Most likely black-capped chickadee this time of year and in a box. My bird nest guide describes it as

a moss base and cup of plant down, fiber, hair, wool, feathers, and spiders’ cocoons

Thank you!
