Male Eastern Bluebird. Their vibrant blue feathers during breeding season are easy to spot between the trees, even under low light conditions.
Shortly after our return from Oregon I saw a pair of Eastern Bluebirds inspecting a nest box I have built for this particular species a couple years ago. I saw both, the female and the male last weekend again and my hopes grow that they may take possession of the place and built a nest. The biggest competitors are the House Wrens and the first one has already arrived. Last year a male wren stuffed a lot of loose little twigs and branches into the hole and as I later found out, all on top of a bluebird nest. The wrens are much more aggressive and the bluebirds had no chance. We have several bird boxes for the House Wrens but they have their own mind and choose whatever place they like the best. Since we had a breeding pair of Eastern Bluebirds in 2020 in another nest box I still hope it will happen again.
The colors of the female are much more subdued. After a male has attracted a female to his nest site, the female actually builds the nest. Both parents feed the brood.
