A family of eastern bluebirds might be wintering in the park. At least six bluebirds perched on the fence and the fence posts of The Bison and Elk Enclosure in the morning on the first day of December.
A few of them flew to a tree outside of the fence as I walked by. The rest went the other way and landed on a tree inside of the fence. One of the bluebirds in the nearby tree was a young female. I saw an adult female bluebird in this tree in May.
According to the map in my bird book (Peterson Field Guide to Birds of North America), this area is a hundred miles north of the winter range of the eastern bluebird. On January 1, 2016, a flock of eastern bluebirds sampled the berries in the bushes near the garden a short walk west of this tree.
Have these bluebirds decided to stay all year in the park? Did they summer to the north and stop here instead of traveling further south? Are they late on their migration travels?
The bluebirds observed me with silent curiosity. They know where they have been and why they are here. I am left to wonder.
