I have recently found a lot of nests that are made with small wood chips inside the nest. The nest is so strong that I cannot pull larger pieces of wood from it without destroying the entire nest. This is the first year that I have noticed this type of nest. I have lived in Oregon since birth and have had a need for wood for the fire all my life. I am unable to load my pictures from my phone to my computer at the moment. But if you would like pictures I can text to someone. Should I be concerned about these nests? There are a lot of them in this wood pile
