I haven't seen these birds before, but I'm not the best birder in the world, that's for sure! The birdhouse is an old bluebird birdhouse that has remained empty through the years. Boy, were Rick and I surprised to see two Bewick's Wrens entering the birdhouse from an opening by the roof, and then exiting through the entrance/exit hole, a few minutes apart. Squeaks were heard from the chicks inside.
This wren, which is described as "noisy and hyperactive," has a distinctive call. It ends with a lispy "twee, twee, twee." I've been wondering what bird was making those calls, so I'm happy to come face to face with this little bird with the white eyebrows. Nice to meet you, Bewick's Wren! Glad you brought your entire family to our place in Anchor Bay.
To hear their call, here is a link to the Cornell Lab of Ornithology: https://www.allaboutbirds.org/guide/Bewicks_Wren/sounds
