We spent at least an hour below the dam watching dozens of gulls fly from the Columbia to a frozen pond and back. Unfortunately, none of them were Black-headed. Some other birders eventually showed up and told us that our target gull was roosting on a driving range.
We gunned it to School Flat Road and sure enough there they were. Twenty Rosy-Finches! Unlike with the Black-headed gull, we were able to spend some quality time with the rosy-finch flock. The members foraged on the ground, defended their personal space, and preened in a tree. Eventually, the flock flew behind a hillside and it was time for us to return to Portland, another successful trip to northeast Oregon in the books!
