My neighbor came across this house sparrow nest with three little eggs in it, and called me to see it because she knows I love to paint all things bird-related. You may wonder why the title "Certain Teed." We are having a new roof put on our house and the sparrows included in their nest a very long piece of plastic packaging material from a Certain Teed product being used on the roof. The roof project just started five days ago, so it didn't take long for the nest builder to forage for interesting materials. Two scraggly feathers are also included in the nest.
