Today the black-capped chickadee appeared an hour later (12 noon instead of 11), and worked on the limb cavity for about 6 minutes. You could see it taking out pieces of tree and dropping it to the ground. No nuthatches showed up but when a male house finch flew into the tree about 10 feet away and started singing, the black-capped chickadee left. The house finch has done quite a lot of singing from this tree since then on and off and as of an hour later, the chickadee hasn't returned. Maybe tomorrow?

I live in Summit county and I observe Chickadees and Nuthatches hanging around together all the time.

Is there a relationship between the two?

They are competitive for food sources and nest sites and often found together in similar habitat. I don’t believe anyone has discovered anything other than that between the two species (like some sort of symbiotic relationship).

Here in SE Larimer Cty we have Mountain chickadees and Pygmy nuthatches together. They both come and snatch sunflower seeds and I’ve not seen them fuss or fight with each other – or with the juncos hereabouts. – Dave Hyde/nr. Storm Mountain
