I drove up to Pueblo Mtn Park on Sunday to see the reported nesting Acorn Woodpeckers. Both the male and female Acorn Woodpeckers didn't show up right away but I wasn't able to get there until the hot midday. And I did not hear a Grace's Warbler singing though I didn't remember that they were further up the hill from last year and didn't go up there.
I observed both the male and female Acorn Woodpeckers spending a lot of time inside the nest hole, mostly separately but maybe together at one point. I did not observe any feeding behavior or even bringing food to the nest. When they approached the nest they went inside quickly. I did get some photos and have uploaded some onto my
Birds and Nature blog. I will upload the photos of the female tomorrow.
